actually they've been playing it smart so far. Now that we live in a world where people like Jason Todd, they can do stuff with him in that specific universe, especially since Jason is still the 2nd Robin, but Bruce didn't want Tim to know about him due to his own failure. Crazy thing is Joker of all people had a valid reason in trying to kill him (being that if he let Jason free,, he would continue to kill his own people for no reason beyond being mere henchme helping his plans out). And even crazier...Harley Quinn thought Joker was going too far, got kicked out the room, then called Batman up to stop it...then Bruce ****ed up by saving Joker of all people first. That way it gave Jason a reason to have a hatred for Bruce in this world, and it explains why he was never in Batman TAS ...and even better...Batgirl getting pregnant isn't canon
