Revenant - a person who has returned, especially supposedly from the dead.
After the disastrous attempt to force Batman to kill the Joker, Red Hood is trying to pave his own way as Gotham's newest vigilante. Estranged from the Bat Family, Red Hood is attacked by the Court of Owls and saved by a familiar face. Although this Talon doesn't remember him, he still asks for help. Well, he did just save his life. How can Jason refuse?
