OMG. What does that mean for Dick? He shouldn't have to give up being Batman, he earned it, and TBH, it was blatantly obvious that despite anything that ever happened between them, Bruce had always intended that, if anyone, Dick be his sucessor. Also, what does it mean for Tim? He more or less became Red Robin because Dick wouldn't let him continue as Robin and he wanted to find Bruce, so when he does that, then what? Go back to Gotham? Hey, maybe he could become the proper new Nightwing (Not that thing with Christopher Kent, that was dodgey, I mean, I know Superman was where the idea came from, but Nightwing should remain in the Batman family as whoever the sucessor to Batman is. Not to mention the only other option is Damian becoming Nightwing in a few years which would be horrible, it would be Jason as Nightwing all over again.
