Robin has a revelation and comes to realize the path in front of him becoming Nightwing, is something he doesn't want. In this scenario though, he doesn't want to be just another bird. He wants to prove he's was more than that. More than some youthful ward that was once the ideal protégé of Batman. Practically like Bruce's own son. No longer to being Batman's youthful ward,or faithful companion. What if he became someone else someone besides, Robin: The Boy Wonder. Perhaps someone's new protégé, a new sense of direction, thus bringing a new path, a new destiny. Who better would that be, to fill the void that Batman once filled? Well I suppose you'll have to, riddle me that...
