Henry Allen

"When you need me, I will be here, but right now, Central City doesn't need you to be Henry Allen's son. It needs you to be the Flash, my kid, the superhero."

- Henry Allen to his son.

Dr. Henry Allen is the father of Barry Allen, the husband of the late Nora Allen, and a good friend of Joe West. Along with the people at S.T.A.R. Labs, and Joe and Iris West, he also knows Barry's secret; that his son is the Flash. After Eobard Thawne was erased from existence, Barry was given a recording where the former confessed to murdering Nora Allen. Henry was released from prison, though he told his son he had to leave town as he didn't want to get in the way of his son being a hero.

Biography
When his son, Barry, was 11 years old, a tornado-like blur came in to their home, and in the middle of the tornado seemed to be a figure. Henry held Barry back, and before either of them could do a thing, the blur murdered Henry's wife and swept Barry 20 blocks away from his home. Following Nora's death, her murder was pinned on Henry and he was sent to jail in Iron Heights Prison.

Henry disallowed Barry from seeing him as he didn't wish him to see his father in jail. However, Barry eventually snuck in by running to the prison. Henry assured Barry that he couldn't help him in any way, so instead he wished him to be the good boy that both of his parents believed he was.

Incarceration in Iron Heights
In late 2014, Henry was still incarcerated in Iron Heights. He had Barry come to visit him, and despite him previously having told to change his name out of embarrassment, Barry stated that he was incredibly glad that he didn't, as he was more than proud to be Henry's son.

Eventually, Joe went to visit Henry. Joe explained that Barry was fine, he had just felt like it was long since due that he visited Henry. He promised that he finally believed Henry, that he knew he hadn't killed Nora, and he was finally reopening the case. He apologised, though Henry stated that he never cared about Joe's belief in him, but his belief in Barry. Suddenly, The Mist entered the room and began suffocating the guard. He soon moved on to Joe, causing him to choke, before Barry came, in disguise, and saved him with a counteracting injection. Henry watched as the seemingly unidentified man saved Joe's life. Barry turned towards his father, blurring his face so he wouldn't recognise him; Joe soon came back to life and Barry ran off to stop The Mist. Barry later came to visit his father. He expressed how he missed his mother, which led to Henry telling a story about when Barry learnt to walk: being a late bloomer, Nora believed that he'd walk when he had some place to go. Finally he learnt how to walk, but rather than walking, he ran in to his mother's arms, finally having some place to go.

When the man in yellow reappeared in Central City, Barry visited his father again, saying he had had his mother's murderer but let him escape, and saying that because he had failed to stop him, he was now partly responsible for Henry's imprisonment. Henry told Barry not to blame himself, that the man in yellow had already taken enough from their family, and that Barry should live his life rather than let Nora's killer take anything more from them. He also revealed that he had long known about Barry's unspoken love for Iris.

During Barry's investigation of Clay Parker's breakout of Iron Heights, Joe arranges for Henry to be moved by a police officer past the crime scene so that him and Barry could enjoy a short time together. Later, without Barry's acknowledgement, Henry asks around the inmates for information on Clay so as to assist the investigation. Barry tells Henry to not endanger himself anymore, which Henry consents to. Despite this, Henry stays in contact with Joe and continues to search for more information. As a result he is stabbed and beaten by Julius, an inmate working under Marcus. He reveals that he continued to investigate because he wanted to be there to help Barry like Barry did for him. At Barry's insist, he tells him Julius harmed him.

The next day Henry is seen in his infirmary bed, discussing Barry's recent date. He then mentions The Flash in the newspaper, recollecting the time he witnessed The Flash save Joe from The Mist. Henry then notes the coincidence of him recently being harmed by Julius and of The Flash extending Julius' prison sentence due to his breakout, comparing it to The Flash saving Joe, implying that he believes Barry is The Flash. Barry denies being The Flash, saying that Henry would have been the first to know. Henry then states that if The Flash were his son, that he'd first tell him that the world is dangerous and that he should be careful. Second, he would tell him that he is a hero who is saving many lives, and lastly that his father would be proud of him, leaving a teary-eyed Barry looking up at Henry.

Henry was later kidnapped by James Jesse, who wanted to use him and his connection to the CCPD as an bargain in case his plan failed. However, Barry ended up rescuing him at the last minute and subsequently confirmed his father's theory of him being the Flash by removing his mask.

Before returning to prison, Henry received a small tour or S.T.A.R. Labs and thanked all members of Team Flash for being there for Barry.

Personality
Henry is kind, caring, sympathetic, compassionate, selfless, and intelligent, he is a loving husband and father, as he loved his wife Nora very much, when the Reverse-Flash stabbed her in the heart with a knife, he did everything he could to save his wife, he was devastated by her death, he loves and cares about his son Barry.

He used to be good friends with Joe West, until the latter chose to believe he was guilty of killing his wife, when Joe came to visit him, Henry was not happy to see him, partly because he did not visit him for 14 years, and mainly because he believed he was a murderer, despite his anger towards Joe, when the latter was poisoned by Kyle Nimbus, he called a guard for help.

Joe and Henry eventually reconciled when Joe came in to tell Henry he now believes Henry is innocent and vowed to get him out sooner or later.

As some may expect, after multiple clues, Henry eventually discovered that Barry is indeed the Flash. However, when an incident in Iron Heights caused Henry to be stabbed, Barry immediately questioned his father for the name of the person who did it. He was surprised to hear that his father had assisted Joe with an investigation for the end-purpose of helping out Barry. Upon the resolution of the case, Henry held a photo of "the Flash" that Iris had caught, which was front-line paper (and it was a clear resolution photo), which showed his face, which Henry had seen twice. While it was never confirmed, by his exchange with Barry in a conversation about "what Henry would tell him" if the Flash were indeed his son, it was strongly hinted that Henry had put the pieces together.

Henry is also adamant in pertaining his son's life above his own, to be full and lively. Evidenced by his refusal to support Barry in going back in time to prevent his wife's murder. While Henry was indeed sad over this decision, at the prospect of regaining Nora, he reaffirmed to Barry that neither he "nor Nora would approve undoing history" to change the person Barry had become. Henry cited that he didn't want Barry's current growth to be undone by changing history. He even went to further state that while he was in awe of the man that which Barry had become, he also affirmed that Nora would have been equally proud and would also object to his plans to save her.

Henry could be considered someone who "gave up on" his own life, but not in a suicidal sense - He realized his son had a bigger purpose than him, largely because of the impact that, as "the Flash", had changed Central City, and may have eventually realized the full-scope of what he would or could become. Through this, Henry supports his son, and while he may not agree with his judgement, like going back to stop Eobard from killing Nora, his wife, Henry objected, but reaffirmed to his son why it was better. Henry has all but given up on getting out of jail, and even tried to persuade Barry from pursuing "the man in yellow", AKA, the Reverse Flash, throughout the first season. It could be argued that, while Henry now knows what Barry could do, he believes there is a natural order, and that with Henry being sentenced to life in prison, there is a reason he is in there. And, in some instances, it shows that Henry believes his "reason" for being in there, was for Barry.

Through this, Henry has accepted his wife's being gone, and has learned to live with it, but also learned to live "alone", in that he realizes he can't be apart of Barry's life. And while he wants to, badly, he wants Barry's life to be his own, and not allow Barry to undo his own growth for the sake of him or his wife.

Due having a history with science from his path to being a doctor, Henry believes the natural order of things should not be interfered with. As a result, he protested against Barry going back in time to save Nora, even if it meant Henry would be able to raise Barry with his wife, and his lost honor as a doctor and innocent man would be restored.
