Anger: The Huntress wouldn’t torture someone to find out who killed Barbara Gordon... would she?
Bargaining: Black Canary starts looking for Lazarus Pits and that weird "resurrection lightning" from the Lightning Saga.
Depression: Power Girl had a lot of unresolved issues with Barbara Gordon. Looks like they are staying unresolved.
Acceptance: Batman and Commission Gordon have seen a lot of death. While you don’t get used to it, you do accept it.
