Even after Batman lost Jason, he did go on to, loose Stephanie too. It almost seems as though he didn't take anything from his experience with Jason. Also, I agree with Kagome 654's comment about Jason's death in the first place. He wasn't killed off to enrich story-lines, it was a 1-800-kill'em vote by fans. Sure, some really great writing came about afterwards, but none of that is invalid if he comes back. Instead, there could be a newer turn of story. Batman could forever mourn Jason's death, which would be the same song and dance as with his parents, or there could be development towards the two facing off with each other. Sure, they briefly fought in Winick's Under The Hood, but it was handled roughly and almost like a violent quickie in a closet = cramped and unsatisfying (I did like his idea of bringing Jason back, and the fact that it would really cause friction in Batman's life, it needed to be handled with greater care though). There are tons of issues to be explored with these two: Batman's guilt, Jason's anger and possible Lazarus pit insanity, Batman father issues (rampant in all his kids, but probably the most for Jason IMHO), their differing ideologies since Jason was killed, he's got a completely new reason to be hard on criminals. Batman, while suffering losses, only was affected indirectly. What about all the unresolved issues of Jason's past dependance on Bruce? Before he died, he was almost following in Dick's footsteps with struggling for independence (albeit in a much darker fashion), but then he died. Is there any lingering childish rebellion? Is part of Jason's current actions influenced by never gaining his own identity away from Dick's shadow and Bruce's demands? There are a lot of things that could be done if given to the right writer. Sorry for the rant, I just really like Jason's character, always have. It's very disappointing to see him handled less like a character to be developed and more like a handy 'Batman angst' plot device.
