That still really doesn't account for where Dana is or what her status would be. IIRC correctly she died in Bludhaven as she was being treated in a clinic there. She was Tim's step mom. Would Bruce be able to adopt Tim if she was still alive? If she's dead then how did she die in this continuity, since Bludhaven is still standing?
Jack's death also raises other questions since it's connected to the surrounding events in Identity Crisis.
