Yeah, but slowly getting back in the harness, dragged in by wannabe Nightwings that need nursemaiding.
His kind of memory loss is temporary, probably only lasting this long because he actually wants it to. He seems to have repressed a desire to come to a dead stop, and it's come to the fore thanks to the amnesia. Because of it, he avoids anything that might trigger complete recovery. I regard this as an interesting exploration of a previously hidden part of his character. Hopefully this will continue to be reflected and explored when the amnesia is gone. I wouldn't mind a less boring Nightwing. This is kind of exciting. Much better than just killing him off.
Because let's face it. Robin, for him, was a long long time ago. He's his own man now. As were Arsenal and Donna.
