Bruce comes back from the dead and wants to make things better. Bruce comes back from the dead and Tim was the one who brought him back, so it's obviously Tim who'll know best how to help him reconnect with everyone.
It's Tim who should give him advice on how to bond with Dick. Dick has always been his idol, after all. Tim would know best how to bring him back, and he does. He gives good advice and the two of them begin to get closer.
So Bruce asks about Jason, too. Asks about how to bring his son back into the fold and Tim wished for a brief and brutal moment that it weren't so obvious who the favorite was.
Tim told Bruce to give Jason his space, to loosen his rules, and make it clear that no matter what the Red Hood did, no matter what the Batman believed in, Jason was always welcome. Bruce would always want him.
It worked. Bruce wasn't surprised. Tim was a special sort of bitter.
Bruce asked again for Damian and Tim had to push down his anger. "That boy tried to kill me," Tim wanted to say. "I hate him and I want you to hate him too so that I can remember a time when we had something in common," Tim didn't say, but he got close.
He instead told Bruce how Damian liked art and animals and loved hearing stories of the wonders of Batman.
He told Bruce just how much Damian loved being Robin. Told Bruce to tell Damian what a good Robin he was.
God bless or maybe damn him, but he did and it worked and Tim wanted to start screaming and clawing at something because that would have never worked if Tim tried it and it wouldn't have stopped Damian from cutting his line--something Bruce did not and would never know about.
Bruce asked about Babs. How should he make sure she knew that she was a part of the family? That they loved her and not just for the work she did?
He asked about Steph. How should he make sure she knew that she was more important than his rules and that, if something else should go wrong, she didn't need to run away?
He asked about Duke. He never got the chance to get to know him before leaving--not as well as he wanted to, at least. How should he let him know that he was just as much a son as everyone else? That, whether or not his parents woke up, he'd always be welcome?
He asked about Cass. How should he show her that he loves her even though he has nothing to teach her? How can he convey how much he cares about her, his first daughter?
Bruce gets brought back from time and he makes things better. He brings his family back together by following Tim's advice.
Tim brings his dad back from the dead and Bruce changes, becomes a better father.
Bruce changes, but not everything can.
That, Tim thinks, is why Bruce never calls Tim his son.
