"you and me, searching for batman" hmm... wasn't that Tim or am i missing something?
i can’t think of any other scenario so it looks like the writers nuked red robin (which was i guess of dubious canon status anyway because of tim’s new 52 origin and….non-timness) in favor of highlighting damian and his one acceptable brother.
i could be wrong, i didn’t read the issue because i don’t follow nightwing or teen titans, but DC seems to only be invested in dick and damian’s relationship, and damian as bruce’s son is like an abstract concept (i.e. they’ll mention it loads but bruce and damian?? interacting??? what is that????).
