Re: yay matching icons.
Given that it happens only shortly after Jason telling Dick, and I quote, "I guess that's why 'Dad' always loved you best", I doubt daddy-issues solving is in the close future.
I'm okay with Damian, but I would love him a lot more if it turned out Bruce wasn't really his father. Thematically it's better if the Batfamily isn't blood-related, I think, and it'd provide interesting momentum to Damian's character himself.
