If you were Nightwing would you stay part of the Bat-family? I know the kind of immediate response is yes but really think about it on the New 52 continuem. Your Dick Grayson, your parents were killed infront of you in your teen age years, a man takes you in (batman) trains you to be a superhero, and within 1- 2 years you have a fallout, leave and become NW, at some point you make up and kinda do your own thing, seeing each other from time to time.
Now if in DOTF, Bruce kept all these secrets from you that have so far ended up getting two people killed, your circus attacked, and whatever else happens in DOTF. Would you stay a member of the Bat-family. think about it really, Bruce and Dicks partnership isnt nearly a solid as it was pre-52, they only stayed partners for a few years at most and Dick was pretty much grown up before he met Bruce and from what I see in the NW comics, Dick really doesnt want bruces help for whatever reason, Like funding the carnival or whatever. it could be Dick just wants to be his own man or there could still be a little bit of tension between bruce and dick. and the last time Dick stood up to bruce in Court of Owls, Bruce punched him in the face. I dont know about you guys but if I had someone treat me like Bruce treats Dick, I dont think id stay around much longer.
