Lets just hope that when Flash: Rebirth is finished, Barry is once again dead and Wally is once again the Flash. I like the idea someone had about Barry being the Black Flash now. I don't know how it would be done, but I wouldn't mind seeing Wally put in a position were he has to stop Barry Allen. Imagine Wally walking around, wondering what to do with his life now, with Barry back as The Flash, everyone loving the fact that Barry is back. And again, I don't know how it would be done exactly, but Wally is put in a position were he must stop Barry. Wally West defeating Barry Allen and once again becoming Th Flash would be the definitive moment in Wally's life.
