I want to see his Bruce hug all his sons and tell them he loves them. Even though he's not the most affectionate guy I really think it would make a really powerful and lasting impact on his boys. They see him as a father figure and just want to know that he loves them back like family. They all lost their first family and they can find it again with each other.
Yes the authors were horrible to Jason, I think that if Jason ever met his authors he would kill them, for killing him and then for bringing him back just to be tortured further. I mean nowadays super hero's can't retire, marry, settle down, or even die!
What Bats messed up with in this relationship was that he tried to be Jason's mentor, when what Jason really needed was a father, not a mentor. What both Jason and Bruce needed was exactly this; a hug, a reconciliation of what they both want and need, one, that is to say filial love, a family. Because at the end of the day, when the anger that dominates both of their lives has run its course, they both have nothing, and desire the same thing. Personally though, I think it shouldn't be long before the two reconcile, since it was never Jason's destiny to go rogue like he did, but I do like him taking the Red Hood mantle, and maybe him using it as a hero.
