One of the more interesting details I noticed was the hints of what happened to them after they died. RSOB implied Damian went to hell which is why he's so focused on making amends. RHATO Futures End had it revealed via Jasons' thought boxes that he was in heaven before he was yanked out "kicking and screaming" to return to life. Which might be a huge contributing factor for why he was so miserable when he came back. He didn't want to leave which might be why his soul was missing before Talia put him in the pit. (*1) How would they react to learning where the other was?
I speculated Bruce trying to figure how how Jason came back since his return. How about an actual investigation or at least having them find out Bruce is determined to find out the truth. There's no way I buy the greatest detective just shrugging off the mystery of Jasons' resurrection.
