Question 1 :
Will memories, to whomever it may be applicable to, of the pre-flashpoint timeline be restored to the rest of DCU ? So far heroes such as Wonder woman, Aquaman and likely many others arent showing any signs recollection.
Question 2 : Since, as far i know, Pre-Flashpoint and New 52 Superman are the same person, shouldnt Batman or Wally clear that up for the older (original) Superman by now?. Can you imagine how the older superman would feel if he realized that it was actually his younger albeit new 52 self that died? It would be profoundly saddening, weird and awesome all at the same time! It would reinforce Superman's commitment to the League.
