Laurel Lance (Earth-1)

''For her Earth Two equivalent, see Laurel Lance (Earth Two). For her mother of the same name, see Dinah Lance. For other people who used the Black Canary identity, see Black Canary.''

"Dinah Laurel Lance, always trying to save the world."

- A common saying to Laurel by those closest to her

Dinah Laurel Lance (1985-2016), known simply as Laurel Lance, was a citizen of Star City and one of its most beloved public servants. Laurel was the eldest daughter of Dinah Lance and Quentin Lance, the older sister of Sara Lance, and the on/off romantic interest and longtime friend of Oliver Queen. She was a lawyer who held the position of Assistant District and was previously a former legal aid attorney. However, after the death of her sister she was inspired to take up vigilantism and received training from Ted Grant and later by her close friend and her sister's former lover, Nyssa al Ghul. She eventually joined Team Arrow and became known as the Black Canary, the second Canary of her beloved city.

Laurel was fatally stabbed by Damien Darhk during his prison escape and passed away surrounded by the team just moments before her father arrived. Following her death, her actions as Black Canary were made public by Oliver Queen in order to preserve her reputation as a hero to Star City; her identity as Black Canary is left on her own tombstone.

Early life
Laurel was born in 1985 to Quentin and Dinah Lance, and she had a younger sister named Sara. When she was 7 years old she met and became friends with Oliver Queen, she also met and became friends with Tommy Merlyn at that time as well. When Laurel was 20 years old, at one of Tommy's parties, when her sister Sara snuck out of their house to spend alone time with Oliver, their father and the cops later arrived and Sara was grounded. Sara would later come to believe that it was Laurel who tipped off their father to sabotage her chances with Oliver as Laurel apparently knew about the crush that Sara had with him at the time, however, it remains unknown as to whether or not Laurel actually did this. One month after Tommy's party, Laurel and Oliver began dating and fell in love despite Oliver's reputation as a "frat boy" as her father liked to call him.

In 2007, when she was 22 years old, Laurel broached the topic of them getting a place of their own, citing that they had been together even longer than their friends who were already moving in together. Oliver initially agreed, but later panicked, instead of telling Laurel that he was not ready to move in with her yet, he impulsively cheated on her by having a one-night stand with Samantha Clayton. Oliver then invited sister, Sara, on the Queen's Gambit with him. Shortly after the Queen's Gambit went down, she found out from Oliver's mother, Moira, that Sara was on the Gambit when it went down and, and she realized that Oliver was cheating on her with her sister.

Devastated and angered by her Oliver and Sara's betrayal, Laurel found herself unable to mourn for her sister because of her mutual anger and grief ultimately becoming emotionally numb to it. Following her sister's death over the next 5 years, her parents divorced and her father became an alcoholic with Laurel bailing him out the last 5 years. Laurel also went law school, eventually graduating with offer to work at a prestigious law firms in the country in San Francisco. Laurel eventually turned down that offer to work City Necessary Resources Initiative, CNRI for short. Laurel also became involved in a causal relationship with Tommy over the last 5 years, never becoming serious with him despite Tommy's desire too.

Season 1
As Laurel was working on a case against Adam Hunt with her best friend and coworker Joanna de la Vega, she learned on television that Oliver had survived the boating accident but also learned that Sara did not. Oliver later came to CNRI to apologize to her, but Laurel wasn't interested as she was still angry at him for his betrayal and blamed him for Sara's death. She later went to Oliver's welcome back party to apologize to him for being too harsh on him. Asking if her sister suffered and that she would be here for him if he needed to talk about what happened, Oliver lied and told Laurel that the island did not change him and that she should stay away from him otherwise he will just end up hurting her again. Laurel tells him that the island did change him as he is more honest now. Laurel would be informed that all the money that Adam Hunt stole was returned to his victims, she would later meet with Tommy to discuss that she and Oliver are over but that he is not the kind to be in a serious relationship with.

Laurel helps a client whose father, an honest man, was murdered by Martin Somers. She ran into Oliver again at the courthouse where his death in absentia was being revoked, leading to another bitter moment between the two. Later, Oliver went to her apartment to apologize for pushing her away once again and to eat ice cream with her, mentioning that he missed it while he was on the island. They began to reconnect, but the house was attacked by the Chinese Triad at Martin's behest.

Oliver got in trouble with Max Fuller while at his club and was dragged to a back room to be beaten up by his goons as payback for sleeping with his fiancée at their rehearsal dinner. Tommy tried unsuccessfully to protect him but it was Laurel who quickly took down Max and got him to let them go. Oliver found out that Laurel and Tommy had slept together while he was on the island and tried to talk to Laurel about it, but she told him they did't need his forgiveness or his blessing and left the club. She later spoke with Tommy about what happened.

When Peter Declan was wrongfully accused of murdering his wife, Laurel pointed out that he shouldn't die for someone else's crime. At first the information she found was not enough to free him so she went to the prison to talk to him. While at Iron Heights Prison, Laurel was attacked by the bodyguard of the man who actually killed Declan's wife, but The Hood saved her. Horrified by The Hood's violence, Laurel described him as a "monster" to her father.

After Oliver was arrested by her father under suspicion of being the vigilante, Oliver asked Moira to go ask Laurel to defend him. Laurel reluctantly agreed hoping to get through her father but only ended up arguing with him about how Oliver is not to blame for Sara's death or the fact that her mother left them afterwards. During Oliver's polygraph, Quentin questions him about the scars on his body with Oliver revealing to him and Laurel that he was tortured and that he believes he killed Sara, saddening Laurel. Laurel later meets with Oliver in private at his party, where she reveals that her mother left him and her after Sara's death in hopes that Oliver will understand him. Oliver asks why she doesn't hate him, Laurel admits that she did for a long time but was so busy thinking about her family that she did not stop to consider what happen and now knows that happen on the island was more that he deserved. Admitting that she did not know about his scars and asking to see them, Oliver reluctantly showed them leading to an intimate moment between them in which they kissed. Laurel later appeared after Oliver was cleared of all charges, questioning his polygraph results. Oliver told Laurel that he did want to be seen as damaged, Laurel ultimately admitted that they were clearly still attracted to each other but made it clear that nothing could ever happen between them again.

CNRI lost its biggest sponsor and Tommy suggested throwing a fundraiser for them. Laurel was initially suspicious of his motives, but considering that CNRI needed the money desperately, she went along with it. After seeing Tommy caring for the drunk Thea, Laurel indicated to Tommy that she might be interested in a relationship.

Laurel agreed to go on a date with Tommy. When his father cut him off, she comforted him and told him it was not his money what she found attractive. She encouraged Tommy to ask Oliver for a job and they argued over his insecurities, although they made up soon afterwards.

Laurel went to the Queens' Christmas party with Tommy. After Adam Hunt was killed, Laurel realized that the Hood was only trying to protect her.

After Joanna's brother, Danny de la Vega, died suspiciously in a fire, Laurel asked her father for help. He refused on the grounds that the death was not suspicious, but she stole his phone to contact The Hood. She asked for help investigating Danny's death and they worked together, discovering that Danny's murderer was a man otherwise believed to be dead, Garfield Lynns. Lynns attacked a fundraiser being held for the fire station and Laurel was briefly trapped inside with Oliver. Quentin told Laurel she should keep hold of The Hood's phone as she would find better use for it, although he was actually planning to use her to capture The Hood.

Laurel had dinner with Malcolm Merlyn and Tommy.

When Thea got in legal trouble, Laurel asked her father to get her a deal by reminding him of the trouble that Sara got into in her youth. As part of her plea bargain, Thea had to work at CNRI with Laurel for some time.

Laurel found out that the criminal Cyrus Vanch had been released from prison and asked The Hood for help finding evidence against him. When he had something to offer, he called her and she left a date with Tommy to meet him on a rooftop, not knowing her father was tracking her to capture The Hood. Laurel and Quentin had an argument because he was furious at her for contacting The Hood, while she was furious with him for setting her up and putting her in danger. Laurel was then kidnapped from her apartment by Vanch, who used her as bait to attract The Hood. After her father and The Hood rescued her, she told her father to stay away from her for his earlier actions. The Hood told her he saw how much danger he put her in and informed her he was going to stay away. Laurel's relationships with both Tommy and her father suffered as a result of her activities with The Hood.

Laurel and Thea had a break from working at CNRI and walked through the Glades. Suddenly, Thea's purse was snatched by a man (Roy Harper) who managed to escape. Thea tracked Roy down and Laurel helped by passing on the information to her father so he could arrest Roy.

Laurel helped Tommy celebrate his birthday and comforted him when his father turned up, encouraging Tommy to attend a ceremony in which he was going to receive an award. Afterwards, Laurel received a surprise visit from her mother, Dinah, telling her that she thought Sara might still be alive.

Laurel invited her father to breakfast, not telling him that Dinah would also be attending. She encouraged her father to help Dinah investigate whether or not Sara survived the sinking of the Queen's Gambit in order to prove to Dinah that Sara was really dead.

Laurel got caught up in the investigation but ultimately managed to prove that the photo Dinah has found was not actually Sara. Dinah's confession that she allowed Sara to go on the Gambit with Oliver was what allowed Laurel to reconcile with her. Laurel asked her mom to keep in touch when she went back to Central City. Meanwhile, Tommy distanced himself from Laurel even though she needed him.

Laurel got furious when her father tried to prove Tommy and Oliver were selling Vertigo at Verdant.

Laurel tried to help a family, but the couple was murdered by an assassin. She took in their orphaned son, Tyler, making herself a target when the assassin went to tie up loose ends. She, Tommy and Tyler temporarily stayed at the Queen Mansion, where she briefly discussed about the past with Moira. Later, Oliver comforted Laurel, which Tommy saw and misconstrued though he did not say anything at the time. The assassin was killed by Oliver and Laurel and Tommy were safe to go home, while Tyler's grandparents had been reached and could take care of him. Soon afterwards, Tommy left Laurel, lying and telling her that he was not ready for a relationship.

Laurel confronted Tommy over him leaving her, saying that she still loved him and believed he loved her too, so they could work to overcome whatever was the problem. He told her that Oliver was still in love with her and she should be with him instead. When Laurel went to Oliver and asked him to tell Tommy that he no longer loved her, he refused, saying that he had too many lies in his life and that he was still in love with her. A week later, Laurel went to Verdant to talk to Oliver about how maybe they still belong together and that she ready to admit that she still had feelings for him; however, Oliver lied and told her that nothing between them had changed. Laurel later visited her father, where she revealed that the reason Tommy broke up with her was because of Oliver in which Quentin surprisingly states that he has been different since he came back. Oliver later went to Laurel's apartment, telling her that he might finally be ready to be with her telling her that she knows him better than anyone and that she is more important to him than anyone. Hoping that he did not wait too long, Laurel kisses him telling that he didn't as they began having sex. Laurel was unaware that Oliver had previously encouraged Tommy to reconcile with her and he had been on his way to do just that as witnessed the two of them kissing.

Laurel visited Oliver at the Queen Mansion because he left while she was sleeping. Worried he was getting scared again, Oliver assured her that wasn't the case and told her that she has always seen the best in him and that the island brought out the person that she always saw; leading them to passionately kiss. He also told her to stay out of the Glades that night, but when Moira confessed in a press conference about the Undertaking, Laurel went to CNRI to try and save valuable files for her clients' livelihoods. While she was there, her father called her and told her to get out. She left during the earthquake but got trapped under falling rubble when the building collapsed. Tommy arrived to save her life but was tragically killed in the attempt while her father prevented her from trying to get back to him.

Season 2
A year after the earthquake and CNRI's destruction, Laurel became an assistant district attorney. She was present at a mayor's event that was interrupted by The Hoods, who threatened the district attorney, though Laurel managed to take him down. Immediately after, one of them pointed a gun at her before she could do anything else. Her father, demoted to officer rank, tried to ask her questions about the attack but his boss intervened. Oliver arrived and they talked about how she regretted sleeping with him, feeling that she cheated on Tommy. Later, Laurel met Oliver again at Tommy's grave. They agreed on being friends and she told Oliver how she was going to help the district attorney take down The Hood, still unaware that The Hood and Oliver were one and the same.

Laurel made plans to catch The Hood, determined to bring him to justice for his crimes. When he went to talk to her, she revealed that she was also angry because it looked like he had the opportunity to save Tommy life, but did not. He later went to talk to her again she revealed that she had set a trap for him.

The Canary rescued The Arrow from Laurel and the police. When Quentin angered the serial killer he was hunting down, the Dollmaker, the man targeted Laurel, kidnapping her and attempting to kill her while Quentin watched. The Arrow arrived just in time to save Laurel's life and The Canary killed the Dollmaker. Laurel realized her misplaced guilt was aimed at the wrong person and that she really blamed herself.

Laurel was having a hard time from recent events, and began drinking heavily and taking anti-depressants, almost getting arrested for a DUI. Both Oliver and Quentin attempted to get through to her but failed. The Canary, revealed to be Laurel's younger sister Sara, was shown to be watching over Laurel.

Laurel was put on Moira's prosecution and was able to convince the DA to offer Moira a plea bargain - life in prison as opposed to the Death Penalty (in case she was declared guilty). Oliver took her out for dinner in order to protect her from the Assassins pursuing her sister Sara. Afterwards, she made a pass at Oliver, who gently refused her and made it clear that he just wanted to be there for her as a friend, not reignite their romance. Tearfully, she then asked him why everyone in her life seemed to end up running away from her. Laurel noticed that her apartment was open and when Oliver investigated he found a knife, which he hid from her. After Oliver left, Laurel took some anti-depressants.

Laurel was appointed lead prosecutor in the Moira Queen case to replace ADA Donner, who had been poisoned with Vertigo. While reviewing the case notes, she discovered Donner's "trump card" (that Moira had an affair with Malcolm Merlyn). Disturbed by what she found, she tried to convince Moira to protect her family by not taking the witness stand, warning that she was obligated to prosecute the case to the best of her ability and would be forced to present Donner's evidence in court if Moira testified. However, Moira still decided to testify and Laurel had to reveal the affair, making a strong case for a guilty verdict. When she encountered Oliver immediately after mercilessly cross-examining Moira, she tried to avoid him, distraught and guilt-ridden at her actions in court.

Sin and Thea sought help from Laurel about Max Stanton. Laurel discovered that the Blood drive Max donated blood in required a psych test, which was unusual but not illegal, meaning that she could not help Sin further.

Laurel began investigating Sebastian Blood, whom she found suspicious. She questioned him about his past and his connection to Cyrus Gold, asking her father to help her get more information on Sebastian. In the course of her investigation, she discovered the name of Maya Resik, Sebastian's aunt who was confined in a psychiatric institution. She visited Maya, who revealed that she was not Sebastian's aunt, but actually his mother. Maya told Laurel that Sebastian murdered his father and had her committed to hide his crime.

Laurel later got a call from St. Walker's Hospital learning Maya Resik passed away and suspected that she was murdered by Sebastian to prevent her from telling anyone else that he murdered his father. She asked Donner to help investigate the case but Donner refused, not believing Maya was murdered due to her being sick and the lack of evidence about Sebastian murdering his father (Donner did not believe Maya's words because he thought she was insane). Laurel sought help from The Arrow, who helped her search for the files that would prove Sebastian's guilt. Though they were successful, the files had already been removed. Laurel arrived home discovered that her apartment had been ransacked and was arrested by Officer Daily. She tried to pin it on Sebastian but her father did not believe her as she was in possession of prescribed drugs stolen from him. Oliver helped Laurel clean up her apartment after she was released but was knocked unconscious by The Masked Man, who kidnapped Laurel. She woke up at the Starling Cannery with the Masked Man taunting her. Laurel screamed she knew he would pay but the Masked Man grabbed her and told her she knew nothing. The Arrow showed up and engaged the Masked Man in combat. After overpowering The Arrow the Masked Man drew a gun and was about to shoot him, however Laurel picked up a gun and shot and killed him before he could do so. However, when The Arrow removed the man's mask it turned out to be Daily. Laurel was fired by Donner for her drug use and for seemingly being wrong about Sebastian.

Laurel grudgingly agreed to have dinner with her father at his request. When this turned out to be a ruse to get her to attend a drug rehab meeting, she angrily left. She met with Joanna for a job offer, only to learn that disbarment proceedings were being filed against her, making her unemployable. Laurel showed up at Verdant, got drunk and made a scene. Oliver took her keys and got her a cab. When she arrived at her apartment, she saw her sister Sara.

Laurel did not overdose, but was poisoned by a member of the League of Assassins. She told Quentin that she saw Sara, although she was under the impression that it was a hallucination. Soon after, her mother was kidnapped and Quentin tried to comfort Laurel. Quentin revealed to her that Sara was alive but received a call regarding Dinah's location. Laurel followed her father and discovered that Sara really was alive. After the whole Lance family was reunited, Laurel told Sara that everything that ever happened to their family after she left with Oliver was her fault and asked her get out of the apartment out of anger.

Laurel still wanted nothing to do with Sara, refusing to go to her homecoming party. Quentin persuaded Laurel to host a family dinner, hoping he could reconcile with his ex-wife Dinah. At the dinner, things quickly went downhill when Laurel realized that Oliver and Sara had rekindled their relationship. She exploded in rage, arguing with Oliver about her blaming everyone else for everything that had gone wrong ih her life. Finally, a visibly hurt Oliver said he was done with her and walked away. This seemed to shake Laurel, who went to Verdant to apologize to Sara and later showed up at an Alcoholics Anonymous meeting with her father.

Laurel saw that Sara was clearly being pushed away by Oliver and tried to give Oliver advice on how to handle it.

Donner offered Laurel her old job back, if she agreed to prosecute the case against Frank Bertinelli. When Helena Bertinelli took over the courthouse in an attempt to kidnap Frank, Laurel was taken hostage and The Canary arrived to rescue her. In the stress of the situation, Laurel was about to drink again to but got dissuaded by The Canary. In an act of bravery, she insisted on staying until all the hostages were freed and helped The Canary battle Helena's thugs. However, Laurel got recaptured after the masked vigilante was defeated by Helena. Laurel tried to persuade Helena to let the hostages go by explaining that they had a great deal in common, but the Huntress responded by slipping out of the courthouse and taking Laurel along with her. Later, when The Canary defeated Helena in battle, Laurel convinced her sister not to kill Helena.

Afterwards, DA Spencer apologized to Laurel for Donner's having used her in his scheme to lure the Huntress out of hiding, but said that Donner had no authority to reinstate Laurel. Laurel then blackmailed Spencer into rehiring her by threatening to reveal Donner's scheme to the public if she was not given her old job back. She quoted Helena, mentioning that someone recently told her that 'once you let the darkness inside, it never comes out'.

Laurel visited Sebastian prior to his debate with Moira Queen and apologized for suspecting him of murdering his father. Laurel was later visited by Slade Wilson, who revealed Oliver's identity as The Arrow.

Laurel has a hard time dealing with Oliver's identity, mainly because revealing the Arrow's identity is the only thing that could release Quentin Lance from prison. After she sees Sara's wounds, Laurel is nearly heartbroken on learning her sister's true identity. Quentin is then attacked by a prison inmate and Laurel rushes to see him. Quentin then persuades her to keep the secret about Oliver Queen after telling her to think about the difficulties the vigilante has to face. Laurel, finally at peace with the vigilante's identity forces the D.A. to release Quentin and then visits Oliver and hugs him, saying that he is one of the few people she values in her life.

After Moira Queen's death, Laurel resumed her investigation of Sebastian Blood, confiding her suspicions to her father and asking him to help her. She managed to plant a bug in the mayor's office, allowing Kelton to hack his computer and search his files. They discovered proof of his involvement in Moira's death in the form of a press release offering his condolences to the Queen family, dated the day before Moira was killed. Given Oliver's disappearance, Laurel contacted Diggle and Felicity. She appeared all of a sudden at the Arrow's hideout and revealed to Oliver that Slade told her about his secret identity. She insisted that Oliver should continue fighting for the sake of his family and friends and not surrender to Slade, stating that she knew him better than anyone else and that he never gives up.

None of this seemed to sway him, but then she informed the team that Mayor Blood was working with Slade, and emphasized that this was no longer just a personal conflict between him and Slade, but involved all of Starling City, which finally galvanized him into action. When Team Arrow left to confront Slade's army, Laurel asked to join them, though Oliver refused as she would not be safe. Nonetheless, she ended up following them. When one of the Mirakuru-enhanced prisoners began choking the Arrow, she bashed the prisoner with a pipe, distracting him and allowing the Arrow to gain the upper hand. When she and the Arrow were cornered by Slade's soldiers, Oliver shot an explosive arrow towards the ceiling, causing a cave-in.

Laurel got trapped by rubble from the cave-in, but managed to escape by following Oliver's instructions to shoot an explosive arrow with his bow. Oliver was reluctant to leave her, but she told him the city needed him more than she did. On her way to the police station to meet her father, she was attacked by one of Slade's soldiers, but the Canary appeared and rescued her. Laurel told Sara that she knew about her being the Canary and encouraged her dejected younger sister, who believed herself to be beyond redemption. She witnessed Sara rescue a child from a burning building, then both of them reunited with their father at the police station.

Laurel was later abducted by Slade, who wished to avenge Shado's death by killing her, whom Slade believed to be the woman Oliver loved. However, Oliver managed to trick Slade and defeated him, saving Laurel. Sara gave her black jacket to Laurel afterwards.

Return of the Church of Blood
Following his injury, Quentin was taken to the hospital and placed in to a medically-induced coma, in which he stabilized. Laurel constantly stayed by his bed, so much so that a doctor insisted she take some time off from her father. Laurel decided to take the woman's advice, and went outside to call her sister.

Sometime later, Laurel began questioning Hoshaw Tolibao after he held a woman hostage at gunpoint. He claimed to need no lawyer, as he was righteous and his god, Brother Blood, would protect him. Laurel, shocked at the information, relayed it back to the team, who came to the conclusion that someone else had to have taken up the name. Laurel watched over an unconscious Roy, commenting on how he resembled her father. She later went to visit her father. While she was there Sara also visited, which caused Quentin to wake after weeks of being in a coma.

Sara's death
Five months after her abduction by Deathstroke, Laurel was assigned to prosecute Vincent Steelgrave, after Steelgrave was apprehended and delivered to the police by the Arrow. Once Laurel presented the evidence gathered by the Arrow, Steelgrave accepted the plea for fifteen to twenty years. Laurel met Oliver Queen in front of Starling City Courthouse, as Steelgrave was being transported to prison, and told him about Steelgrave in a celebratory mood. When Oliver asked her why she had invited him there, Laurel led him to a speech her father was giving nearby. The two listened as Captain Lance announced that the Starling City Police Department had disbanded the task force charged with capturing the Arrow.

Laurel's father was hospitalized that night after a failed attempt to capture Werner Zytle with the Arrow. Laurel visited her father at the hospital in the morning and berated him for still going out in the field despite his health problems. When asked why he kept pushing himself, Lance told Laurel that was the only life that he knew and stated he did not know what he was otherwise. Laurel answered by saying that he was her father, and she needed him. That night, Laurel met Sara, who had just arrived in Starling City, at a rooftop. The two sisters warmly embraced each other, and Sara asked Laurel how their father was. When Laurel answered seeing Sara would help him, Sara asked her not to tell Captain Lance she was there. Laurel was called in to backstop the interrogation of Zytle at the police station by his boss. As Laurel was leaving, Sara fell down from the rooftop, having been shot in the chest with three black arrows. Seeing her sister's death, Laurel hugged Sara's body as she cried. Not knowing where else to take her body, Laurel took Sara to Arrow's headquarters. Oliver, along with Roy and Felicity, found her in the morning, covered in Sara's blood, still crying by the body.

When Oliver promised Laurel he would find Sara's killer, she told him that when she had thought Sara died aboard the Queen's Gambit, all she could do was scream with rage, but this time she was going to help catch the killer. Oliver objected she should take care of herself and her father, prompting Laurel to say telling her father about Sara's death before they caught the killer would kill Lance. Laurel left, saying a bar was the last place she should be then. When Diggle found a mercenary archer, Simon Lacroix also known as Komodo, by going through the A.R.G.U.S. database, the Arrow followed Komodo as the mercenary was trying to kill a man named Erlich Kelso. Laurel watched the fight between the Arrow and Komodo on street cameras from the Arrowcave with Felicity, and was furious when Komodo escaped. Laurel went to the hospital Kelso was held under protective custody and lied her way through the police officers at his door. She harshly questioned Kelso and tortured him until Kelso told her they were working for a deal to build a pipeline for Amertek Industries. Before he could say more, Kelso was killed by Komodo who shot him with a single arrow through the heart from the building across. Captain Lance arrived at the hospital, worried about Laurel, and confronted her about the lie Laurel told his officers. When answered she needed to talk to him, Lance asked her to go home and let the police handle it. Despite seemingly agreeing, Laurel contacted Felicity to meet her at Verdant so she could tell Team Arrow about what she learned from Kelso.

By following the money Amertek paid Kelso and his partners, Felicity discovered an Amertek board member named Tom Weston had authorized the payments. Theorizing Komodo was paid to stop the deal, they determined his next target would be Weston who was attending Ray Palmer's Star City Pledge event. When Laurel tried to go after Komodo, Oliver argued she would be killed if she went and told her he would catch Komodo this time. Unwilling to stay behind, Laurel took a gun and went after Komodo anyway. She caught up to them just as the Arrow subdued Komodo. Seeing her with the gun, the Arrow tried to talk her out of revenge. Komodo denied having killed Sara, but was unable to convince Laurel as she pulled the trigger only to discover the Arrow had taken the bullets out of the gun. Back at Verdant, Oliver told Laurel Komodo's alibi of being in Blüdhaven had checked out. He told her it would take time to capture Sara's killer because the trail had run cold and urged Laurel to talk to her father about it. Following Oliver's advice, Laurel went to the precinct to talk to her father, but she was unable to tell her father when Lance's medication reminder's alarm went off. She sidestepped by apologizing for lying to her father the day before. At night, Laurel and Team Arrow put Sara to rest in her old grave from when she was presumed dead after the Queen's Gambit accident. Back at home, Laurel sat by herself with Sara's black leather jacket.

Training with Wildcat
Next week, Laurel was assigned the case of a break-in allegedly perpetrated by Tom Bronson. She went to the Wildcat Gym to question Bronson's fighting teacher Ted Grant. When he was told that witnesses had placed Bronson at the scene the previous night, Grant claimed Bronson was with him at the time, causing Laurel to angrily accuse Grant of perjury. Despite admitting to nothing, Grant answered that some people in Starling City were dealt bad hands and that he was willing to lie to keep a good kid who made a mistake. Seeing Laurel's rage, Grant invited her to train in his gym in order to work off her rage.

In her next AA meeting, Laurel confessed she was feeling rage over something she could not say and admitted she did not know what to do with it, before listening to a woman named Erica share being beaten by her boyfriend. After the meeting, Laurel told her father Erica was giving a similar share every month and that it had been getting worse. When asked if he knew the boyfriend had eight assault charges against him, Quentin answered that he knew but the police acting on the confessions would defeat the purpose of the anonymity of AA. Deciding to take justice into her own hands, Laurel followed Erica's boyfriend and assaulted him with a baseball bat while wearing a ski mask and her sister's jacket. Laurel managed to get a few hits at first, but was soon overwhelmed and beaten severely. She was taken to the hospital where she was visited by his worried father who pleaded her to promise never to do something like that again. Laurel promised and told him she had made a mistake. Breaking her promise, she went to Verdant to speak with Oliver Queen. Seeing Laurel's injuries, Oliver asked her what had happened. Laurel told him and asked him to train her so she could get justice outside of a court room. Oliver flatly refused, saying Sara would never forgive him for it. Having been denied by Oliver, she went back to Grant instead who accepted training her. After she left the Wildcat Gym, Laurel went to the cemetery to visit her sister's grave where she encountered Nyssa al Ghul who had also come to pay respects. After praying in Arabic, Nyssa offered Laurel her condolences as well as her father's, causing Laurel to retort angrily she did not want their condolences. As Nyssa was leaving, Laurel stopped her by saying Sara would not have been killed with arrows in the chest if she had not met Nyssa. Nyssa answered she had found Sara alone and starving, and that she loved and protected her. Seeing Sara's jacket on Laurel, Nyssa told her she had given it to Sara and Laurel was not fit to wear it before leaving the cemetery.

Next morning, Laurel was contacted by Oliver Queen and told before her death, Sara had asked her father for information about something named "Jansen." Heading to the precinct, Laurel questioned Captain Lance about what Sara had asked about. Her father explained that Sara had been in Starling, but asked him not to tell Laurel, and that he had given her the last known address of Ken Zhi Jansen. Seeing Nyssa walk into the precinct, Laurel went to confront her. Nyssa figured out Laurel had not told her father about Sara's death, and although believing he had the right to avenger his daughter, she did not reveal it to Quentin because Laurel asked her not to. Quentin gave Laurel Jansen's address, and she went to wait in the Arrow's headquarters as the Arrow, Arsenal, Nyssa, and John Diggle went to investigate the address.

When they returned, Oliver explained to Laurel Malcolm Merlyn was alive, and Sara had been tasked to find him. Hearing that Oliver had tagged Merlyn with a tracer arrow when he had a clean shot at him, Laurel angrily asked him what he would do when he found him. She pressured Oliver into killing Merlyn, but Oliver adamantly refused, causing Laurel to storm out of the room. Outside, Nyssa caught up to her and promised that they would find Merlyn, and she would kill him.

When Nyssa kidnapped Thea Queen to set a trap for Merlyn the next night, Oliver asked Laurel's help in tracking them down. Laurel did not find anything specific to Nyssa or Thea, but she discovered the smoke signal Nyssa was using to send Merlyn a message on city cameras. She went back to the foundry and gave the location to Oliver so he could rescue his sister. After the rescue, Oliver returned with Nyssa and told Laurel Merlyn had not killed Sara, as well as warning Nyssa to stay away from Merlyn as long as he was in Starling City. When Laurel asked Oliver if he was sure, he told her he would not let Merlyn leave otherwise. Nyssa visited Laurel while she was training at the gym, and told her she had proven to be worthy to wear Sara's jacket.

When the cyber-terrorist group, Brother Eye, shut down power in the Starling City, Laurel was called in to the police department to act as the district attorney, because the DA was visiting at the Coast City. Protesters gathered in front of the Starling National Bank after the Brother Eye threatened to reset the balances of every accounts to zero in banks. Trying to make sure no one got hurt during the protest, Laurel pushed the boundaries of her authority and sent an emergency service unit to the bank, but the riot squad only served to exacerbate the situation. Before the protest turned violent, Arrow and Arsenal interfered and dispersed the crowd by using teargas on them. Captain Lance was furious when he learned Laurel had gone behind his back and escalated the situation. After he calmed down, he asked Laurel to talk about whatever was hurting her, but she refused to say anything about Sara's death. Captain Lance accepted her refusal, but urged Laurel to speak to someone else, saying secrets hurt. Laurel took her father's advice the next morning, and confided in Ted Grant about her sister's murder. Grant stated he now knew how to teach her and promised to help her deal with her anger.

She kept training with Ted Grant who also started to use grappling against her during the boxing sparring. After the training they decided to have dinner together. When they returned a body was strung up in the gym and The Arrow confronted Ted. Laurel came in between and said Ted could not have done it as he was with her after closing the gym. She talked with her father who questioned her relationship with her trainer. She left the gym and walked straight past Carrie Cutter who observed the crime scene. Talking with Oliver she said Ted was innocent and had lots of (former) criminals in his gym who might want to send a message. Oliver questioned that she trained with him after he refused to learn her to fight, and told her she had to watch out with Ted.Laurel learned about the body in Ted his hideout and that he was a former Vigilante. She identified the victim as a former magician assistant. Ted told them that both are related to a hotel where a drug dealer got killed before he stopped being a vigilante. Oliver asked Laurel if Ted was aware why she was training and that she wanted to get in Sara her footsteps. Laurel said she can handle it and Oliver said she plays a dangerous game.

Laurel later learned that Oliver had Ted arrested after they found the real killer. Roy told Laurel he probably killed Sara while he was still suffering from the Mirakuru. Laurel asked why and he said he remembered doing it. Laurel was confused as Felicity said the DNA did not match with Roy. Oliver said she needed to focus on Ted right now. Laurel talked with Ted who was in custody. He told her his former partner Isaac Stanzler who helped him during his days as a vigilante. The both of them chased criminals in a way to make the glades safer. He told her Isaac was the one who killed the drug dealer. He said he told Isaac to flee the city to avoid revenge from the drug dealer his gang. Ted got released from prison and he and Laurel talked after which Isaac ambushed and captured them. He forced Laurel to drive them away in their car. He accused Ted of leaving him when he need them the most. As they talked Laurel called Team Arrow. Oliver and Roy gave chase and Laurel used the distraction to toss Isaac out of the car as he tried to shoot Roy. However the car crashed and Oliver and Diggle had to drag Laurel and Ted out of the burning vehicle.

In the hospital she and Oliver talked and he told her he did not want to train her in order to protect her and that he always would look out for her. He also told her Roy did not kill Sara as he remembered killing an officer with an arrow during his Mirakuru-induced rage. Laurel later talked with Ted and said that his training made her doing the right things. She said she wanted him to help her become a vigilante.

While Laurel was mourning at Sara's grave, Thea came up to Laurel and asked why she was there. Laurel told Thea that Sara had died and told her Quentin could not know about it because of his heart condition.

Felicity added that Laurel had a light that Sara never had, and that she should stop trying to be her sister instead of herself.

She takes risks, like contacting the vigilante and can't resist saving people from tough situations, from when Tommy and Oliver were going to get beat up in the night club Poison, to innocent people on trial.

However, Laurel shows she had a big heart, being open-minded and inquisitive, having a tendency to see the best in the people around her. While her anger towards Oliver for supposedly getting Sara killed and cheating on her with Sara made her harsh towards him, at first, a situation exacerbated by the fact that there was still a spark between them. She humored Oliver when he admitted that she should hate him for what he did to her and her sister, but she eventually came around to forgiving him, realizing Sara was also as much to blame. She even wants to get along with her father again, after he used her as bait for the Hood. She was also one of the few people seeing the good person Oliver was inside, even through the snob-front he presents on the outside. When first meeting the Hood, she was disturbed by his methods, she could eventually realize he was, in his own way, trying to help Starling City.

Due to the events of the Undertaking as well as her kidnapping and emotional dilemmas, her personality takes a harsh fall. She also didn't want to face her own guilt, for being partly responsible for Tommy's death, so she tried to blame the Arrow for something that wasn't his fault, until she was captured and almost killed by Barton Mathis. She starts using drugs and alcohol, like her father, to cope with her pain; eventually she loses the respect of her father and Oliver, even losing her job as an ADA. She is reluctant to admit that she has a problem, and spirals deeper and deeper into her addiction.

When Sara returned alive and well, though she was shocked at first, Laurel viciously rejected her. Laurel kept on trying to blame people in general for ruining her life, this behavior of hers continued, until Oliver coldly criticized and corrected her on her actions, and being pressured by her father she began to go to AA meeting groups and tearfully reconciled with her sister welcoming her back. Laurel began displaying her former personality, showing some bravery and stubbornness as she refused to leave without her colleagues who were being taken hostage by Helena. She managed to convince the Canary to help her free the hostages.

Although she eventually seeks help for her addiction and reconciles with her friends and family, it seems that her experiences have left their mark and brought out a darker, harder, manipulative side of her character, as demonstrated when she blackmails DA Kate Spencer into giving her her old job back, and to have her father released from conviction when he was arrested for aiding the Arrow. Later on after discovering Oliver and Sara were the respective vigilantes Arrow and the Canary Laurel not only accepted these facts she confronted them on her own terms; she comforted and inspired them to carry on their crusades during their crisis of faith when Oliver was depressed following Moira Queen's death, and Sara's self-depreciation believing she wasn't a hero due to her time with the League of Assassins while participating in the fight against Slade Wilson's siege of Starling City.

After Sara was killed, dying right in front of her, Laurel was struck with grief, shock and forced herself not to tell it to her father (out of fear it would cause him a heart attack). She became angrier, reckless, and was fueled with a desire for revenge; she sought to help people like her sister did as she tried to assault a man that abused his girlfriend to honor her sister's memory. Determined not to fall into addiction again, she needed "another way" and asked Oliver to train her in combat. When Oliver refused, she turned to boxing as an outlet, then learning of Ted Grant's vigilante past she became his apprentice, asking him to train her. To deal with her pain, and with Oliver's supposed death being the catalyst, she decided to take up her sister's mask, begin to actively fight crime out on the streets and act as The Black Canary. Despite a lot of objections and being unsuccessful at first she kept doing it and slowly became better.

After she was injected by one of Werner Zytle's Vertigo-filled throwing darts, which caused her to see a hallucination of Sara and was almost killed by the latter, she finally realized that Oliver was right (that she was using vigilantism and adrenaline to avoid facing the fact that Sara was dead and she was never coming back); Laurel finally came clean to her father about her sister's death which cost her her relationship with him, though they admit they'll always love one another. Even after she learned Malcolm Merlyn was her sister's killer, and even attempted to take him down which ends very badly for as she is no match for Malcolm, she ultimately took Ted's advice not to train to defeat Sara's killer, but to train for herself, as well as Felicity's advice not to follow in Sara's footsteps but "to be herself". After striking up an unlikely friendship with Nyssa al Ghul who shared stories of Sara with her, and offered her further training, Laurel started to regain her sense of self-discipline and control. She ultimately became a proficient fighter in her own right effectively becoming an official member of Team Arrow, even impressing and being accepted by Oliver.

In the final moments of her life she confessed to Oliver that despite all their complications and history together she truly did still love him and told him he was and always will be the love of her life.

Abilities

 * Peak of human physical condition: After months of training with Ted, Laurel was in top physical condition with fast reflexes and was strong enough to lift a grown man on top of a desk. She later received additional training from Nyssa who taught her the ways of the League of Assassins.
 * High-level intellect/Master Lawyer: Laurel was a respected and highly attorney, graduating law school with an offer to work at successful law firm in San Francisco and later offered the position of District Attorney. Her ability to use the legal system to her advantage allowed her help others and herself both inside and outside the court, while looking at every aspect before making up her mind. Laurel's experiences as a lawyer make her a capable investigator and she has exceptional instincts, as she was correct on her assumptions on Sebastian Blood's corruption. As after learning from Slade Wilson that Oliver is the Arrow she was able to gather the evidence to prove his claims and as a result figure out her sister's identity.
 * Expert hand-to-hand combatant: Originally Laurel was a capable hand-to-hand combatant, this was due to Quentin making her take self-defense classes. Once Laurel decided to become a vigilante, she began further training in Boxing and advanced combat training under Ted Grant. Her training allowed her to match street thugs such as the Red Scarfs, however, she still gets injured from time to time. Nyssa al Ghul, who stated that her fighting style was competent but could be improved offered her training in the ways of the League of Assassins. Over time, Laurel's fighting skills improved enough for her to hold her own against multiple fighters whether they were street thugs or members of the League. After five months, Laurel was now more than capable of defeating multiple enemies of advanced training such as H.I.V.E. soldiers or League members with only minor occasional assistance. Laurel's fighting style seems to be a mixture of Boxing, Judo, and techniques and tactics from the League of Assassins.
 * Expert stick fighter: Throughout her career as a vigilante Laurel had used several weapons such as a stick, her sister's batons, and finally her choice weapon of a tactical tonfa. Laurel's skill with her tonfa had been improved through trial and error, with her later ultimately becoming able to hold her own and later defeat members of the League of Assassins. During confrontations against H.I.V.E. soldiers Laurel had been shown to occasionally wield two tonfas in combat occasionally. While helping Mari against Eshu, Laurel used a metal bo-staff instead of her tonfa, yet she showed impressive skill while using the weapon during battle.
 * Expert Interrogator: As an ADA, Laurel is skilled in interrogating suspects this was demonstrated when she threaten to send one of Brick's men to Belle Reve where he can be killed if he did not aid her. Laurel was also capable of torture, such as when she pressed further on Kelso's injury when she was looking on information on Simon Lacroix. However, it should be noted that she did this under extreme emotional distress after Sara's death and does not believe in torture.
 * Expert driver: Laurel had the ability to drive multiple vehicles and is skilled at it, she is able to pursue enemies in various ways using different vehicles using either a car or a motorcycle.
 * Skilled markswoman/Firearms: Laurel's father taught her how to use gun and she legally owns several firearms. She used a shotgun on Mr. Blank to slow him down long enough for Oliver to rescue her and Tommy, she was also able to kill officer Daily in order to save Oliver's life as the Arrow.
 * Network: Being the assistant district attorney and the daughter of a police captain, she had her own connections with the district attorney's office and the SCPD. Laurel also had contact with Cisco Ramon, who provides her tech such as her new sonic device or her sister's White Canary suit.

Equipment

 * Pistol: Laurel was very proficient in using guns. She kept one holstered on her left leg though rarely uses it, in only of times of emergencies
 * Black Canary suit: Laurel wore a black leather suit while fighting crime as Black Canary. The suit was a modified version of the one used by her late sister. She also wore a black mask and used to wear the blonde wig prior to abandoning it to hide her identity from her enemies.
 * Tactical tonfas: Laurel later used a Tactical Tonfa or side-handle baton, like the one used by police officers. She is able to wield this weapon proficiently while fighting enemies including League of Assassins members. After, five months, she has adopted a second tonfa when facing Hive, to help her deal with multiple skilled opponents.
 * Canary Cry: An updated version of the sonic device that both Sara and Laurel used. This device was made by Cisco Ramon as a favor to Laurel.

Former equipment

 * Expandable batons: After taking her role as Black Canary, Laurel took Sara's bo-staff to fight crime. The staff consists of a pair of expandable batons to fight. They are able to combine into a bo-staff. Laurel later abandoned this weapon in favor of a Tactical Tonfa.
 * Sonic device: Laurel used the sonic device of her sister to stun two criminals and break their car windows. Laurel later abandoned this device when she asked Cisco to make her a modified version the sonic device.

 * Like on the show, Dinah Laurel Lance is Black Canary in the original comic. She possesses the meta-human ability of a super sonic scream, which she can deploy to shatter objects and incapacitate her opponent. This ability is called the "Canary Cry". This has not happened in the show yet, though Sara and later Laurel produced a mechanical version of it. However her Earth-2 counterpart does indeed have this ability.
