Re: A Lonely Place of Dying When Damian starts being an okay guy, I think it'll be more Dick's influence than Bruce's DNA.
It's probably going to go that way, but the fact that Morrisson has spent so much time making a big deal out of Damian's genetics means that the only way for it to stop mattering would be if he's revealed not to Bruce's son after all. He's already Robin because he's Bruce's biological son.
