The Flash rewrite the universe with his Flashpoint but somehow when it’s all done. John Constantine finds himself waking up in his old bedroom. The world isn’t colliding anymore but there’s a small voice of teenage girl waking him up.

“Bloody hell… what are you doing in my room?” He slowly gets up from the bed. His head hurts before the girl frowning at him as she says that she’s his daughter.

The universe is now resetting, this is the new universe after Flashpoint but somehow John still has the old memories about his old universe. Especially when the old one…he doesn’t have a daughter.
