I've always wondered what the rationale was behind slapping that particular origin onto pre-crisis Jason. I mean, I get the feeling the similarity is supposed to feel interesting and coincidental rather than painful, but the story itself really doesn't do enough to make it work, I think. And it really does beg the question of what they were hoping to gain in replacing Dick with a kid who essentially IS Dick. Hmm.
That said though, OMG the art is gorgeous. Especially Dick. Gah.
