I can't believe this thing is still a popular post. I have been away about two years.
A lot has happened since then.
The Elongated Man is finally back (something smells fishy, I hope they don't kill Sue off or make her a villain). Apparently, the Flashpoint thingy with Barry's mom somehow altered Sue's genetics and made her a light-brunette. But hey, I'm telling you. Wally is black now. Are we even allowed to comment on that? I think the proper reaction should be the same as if Jimmy Olsen became black-haired. We all know that's not the traditional look, and we'd probably want a comeback for the next continuity, but it's not a big deal as long as we get the right characterization. With light-brunette Sue, I can just hope somebody paints her hair.
Anyway, I do hope at some point this wally gets to be the only Flash for a long season.
