Henry Allen (Earth-Prime)

"Joe, the look in my dad's eyes that night... It was the same look in Birch's eyes when they arrested him. Look of an innocent man... desperate not to lose his son... Begging someone to believe him. And you do. Yeah, I do. I just keep thinking about all the time my dad lost. All the birthdays we spent, separated by plexiglass. I can't let Birch and his son go through that if he's innocent."

- Barry Allen and Joe West
