Intentions
To protect Earth-1 and beyond from threats that no hero could stand alone. They also fight crime in the name of justice.

The First Alliance:
Felicity Smoak visits Barry Allen in Central City to see his superpowers for herself, meets and helps Team Flash, and assists them in defeating Leonard Snart, aka Captain Cold.

"Flash vs. Arrow"
Barry goes to stop a bank robbery, but is too late to catch the robber. However, he notices that the people in the bank are for some reason, extremely aggressive with each other for a few minutes. During a meeting, Eddie mentions catching The Flash due to him being a number 2 LIL at the crime scene, thinking his intentions getting around is suspicious, though this was rejected by the captain. After talking with them, he took the captain's food before heading to S.T.A.R. labs. Caitlin also gave some advice to Barry about involving Iris whether as the Flash or as Barry.

The police department is able to find the robber via tracer that was hidden in the money. When the police find the robber in a warehouse, one of the officers looks at the robber straight in the eye, causing the officer to become aggressive, and starts attacking the other officers. Barry, as Flash, goes to save the other officers, but hits the floor while saving Joe. Before the aggressive officer can shoot at Joe and Flash, the Arrow shoots the officer down to prevent him from shooting. The Arrow then compliments Flash on his mask before leaving.

At an old warehouse on the outskirts of Central City, Barry and Oliver meet up with Felicity and Diggle. While Diggle is in shock of Barry's speed even throwing his fries in the air, Felicity and Oliver reveal that they are in Central City trying to track down someone who uses razor-sharp boomerangs. Diggle states that he had a cousin who got struck by lightning once, but only developed a stutter. Barry suggests that they team up, but Oliver declines. Barry then takes Felicity to S.T.A.R. Labs, where Felicity works with Cisco to run tests on a boomerang that Oliver recovered. Diggle exclaims to Oliver about freaking out on Flash's speed which he just walks away. At S.T.A.R. Labs, Joe and Dr. Wells talk to Barry about how they don't trust the Arrow, but Barry does trust him and tells them they don't even know him.

The next day, Iris talks to Eddie about the Flash, who Eddie believes should not be out on the streets. At Iris' coffee shop, Oliver and Felicity meet Barry, where Oliver reveals that he found out the bank robber's name: Roy Bivolo. Iris appears giving Felicity and Oliver their coffee, she drags Barry away in private and expresses her amazement and excitement that he knows Oliver Queen. After being persuaded by Felicity, Oliver reluctantly teams up with Barry, believing that Barry only thinks he wants Oliver's help.

At the police station, Joe reveals that the Arrow showed up again last night, and Eddie tries to convince Singh to create a task force to take down the Flash. Singh turns him down, and Iris is hurt when she finds out that Eddie is against the Flash.

Later that day, Barry goes to the warehouse to train with Oliver, who tells him that when he goes into the field, he should be wary of his surroundings. He demonstrates this by shooting an arrow at Barry, who catches it before it can hit him, but gets shot in the back by two automatic crossbows.

At S.T.A.R. Labs, Felicity talks to Caitlin about a theory that different colored lights can change people's emotions, like red causing rage. They think of this because people who turned aggressive claim that before they started acting, they saw some red light. Later, Felicity talks to Dr. Wells, who asks Felicity if she can let him know who the Arrow is, so he can trust the Arrow more, Felicity refuses, saying that it is not her secret to tell. Dr. Wells accepts this, saying he will try and find out using other means.

Barry then comes some time later to S.T.A.R. Labs, and finds out where Bivolo is hiding. Against Felicity's advice, Barry goes in alone to Bivolo's hideout, where Bivolo uses his powers to use make Barry aggressive, and uses it to escape.

Back at S.T.A.R. Labs, Barry is checked by Caitlin, and claims he saw red before Bivolo escaped, yet doesn't feel aggressive. Before Barry leaves, he angrily complains to Caitlin about her constant nagging. He then goes to the warehouse where Oliver is waiting, and Barry starts on a rant against Oliver, and says he doesn't want his help anymore. Barry then goes to the police department, where Eddie is still trying to convince Singh about a task force against the Flash. Barry then starts raging towards Singh and Joe when confronted about the Bivolo case.

That night, an enraged jealous Barry, as Flash, goes to find Eddie, and is about to attack him. Joe goes to S.T.A.R. Labs, and tell the gang that Barry's eyes were glowing red, and he's raging. They decide they need to stop Barry fast, and ask Felicity to call Oliver Queen, revealing that Wells has found out that he's the Arrow, and in the process revealed Oliver's secret identity to the rest of the Flash team. Before Flash can hurt Eddie, he is pulled away by the Arrow, causing Barry to fight Oliver. As Flash and Arrow are fighting, Cisco, Diggle, and Caitlin argue who would win the fight. Oliver is eventually able to restrain Barry, allowing Joe and Dr. Wells to use a device of flashing multicolored lights to stop Barry's rage. Barry apologizes to Oliver for the things he said earlier, Oliver changes the subject and reminds Barry that they still have to catch Bivolo.

Off-camera, Bivolo is caught and placed in a particle-accelerator chamber. Oliver then explains to the Flash team why he chose to keep his identity a secret from them. Later that night, Flash goes to apologize to Iris about attacking Eddie, but believing that Eddie was right all along about him being dangerous, says to him to never contact her again. The next day, Felicity and Oliver go to the coffee shop, saying they are going back and want some coffees for the road. While Felicity and Iris get the coffees, Barry again apologizes to Oliver for the things he said in the field and reveals that he had feelings bottled up inside, but he just never realized it before. Oliver accepts his apology and assures Barry that he can always talk to him about anything, he also gives Barry advice about Iris to let her go, saying that guys like them never get the girl. Before leaving the coffee shop, Oliver sees Samantha Clayton, an old girlfriend of his. The girlfriend later talks on the phone with someone, and says she's picking a hot chocolate for them. Before hanging up, she says, "Mommy will be home soon", implying it may be Oliver's child from the Arrow episode "Seeing Red".

"The Brave and the Bold"
Oliver, Dig and Roy are at a location that is owned by the mysterious man. Both Arrow and Roy shoot at the bombs inside the home, before going inside and learn that A.R.G.U.S. were there as the boomerang man killed an A.R.G.U.S. agent. Despite being told to let it go, Arrow doesn't. Heading back to the Foundry, Felicity tells them who the victim was.

The next day, Felicity receives a visit from Cisco and Caitlin who wanted to see the foundry so she brings them there.

Dig approaches Lyla for information. At the same time, the man shows up at A.R.G.U.S. using the dead guy's id. He then injures a security guard. Lyla tells Dig that it is handled until the alarm went off. The man is killing multiple men.

Dig calls Oliver and gets them to go but Caitlin thinks that they won't get there in time. Dig and Lyla are in a gun fight.

Oliver begins to torture the guy for information, surprising Barry. Barry got upset about it. Barry then brings the guy to Lance before returning and talking to Oliver about his tactics. When Oliver talks about his tragedies, Barry mentions about seeing his mother die. Oliver then tells him if his way is too hard that he knows his way home.

In the foundry, Lyla approaches Oliver to talk about his relationship with Barry.

Dig, Cisco, and Roy were driving together discussing the meta human issue. Cisco however brings up Lyla as Dig's "wife" to which Roy and Dig say that she isn't the wife.

Oliver and Barry arrive at the location and they learn that Digger isn't there but left behind a phone.

In the Foundry, Lyla and the others learn that Digger found them and so Lyla pulls out a gun and begins shooting at Harkness. Felicity grabs a bomb but doesn't throw it until after Lyla is hit by a boomerang. Felicity is freaking out that Lyla isn't breathing.

Dig shows up along with the others and Dig asks Barry to take Lyla to a hospital.

Above in Verdant, Cisco, Roy and Felicity were hanging out when Thea brought them drinks. Roy thanks Thea for the night off. Cisco asks who Thea is and learns that she is Roy's ex and Oliver's sister. Caitlin then shows up. The Star Labs employees worry about how they are not taking it seriously as they give their bad guys nicknames.

Barry and Oliver talk about how he is trading pieces of himself to torture people. Barry tells him that he is full of crap and that Oliver is still human due to his experiences.

Felicity then enters and tells them where Harkness is. He happens to be at a train station. Barry and Oliver head there with Flash removing the innocent people before they talk to the man. He tells them that he had planted bombs around the city and gave them 90 secs for the bombs. Flash rushed off while Oliver stayed behind. Oliver hits Harkness as Flash has to figure out what to do with the bomb. Barry grabs Roy and puts him in front of one of the bombs and then does the same with Caitlin, Felicity and Cisco.

Oliver and the Captain are surprised when they stopped the bombs. The Flash shows up as Oliver doesn't kill the man but stops him from surprising him with an arrow in the back.

Dig is at the hospital when Lyla wakes up and calls her sweetie. He asks her to marry him, to which she says yes. They kiss briefly.

Caitlin promises to send them the results of the arrow that shot Sara. Barry and Oliver return and find out that Cisco had Oliver made a new costume that was better material, along with Barry having a place for his uniform for when he's in town. They promise to do something just the two of them before Barry leaves town.

Barry and Oliver head out alone to fight each other in a friendly fight. Barry tells Oliver that he can inspire people as himself.

When the Legends let time crumble in order to release and defeat Mallus, the barrier between worlds softened. History is now infected with "Fugitives" – magical creatures from myths, fairy tales, and legends. Having been expelled throughout time by people like Constantine, these Fugitives are now returning to our world in droves and making a real mess of things.
