So I have admittedly not read any of Heroes in Crisis, relying on the threads to fill me in on what's going on. I am a huge Wally West fan, as I consider Mark Waid's run with the character to be one of the greatest of all-time. But I have opened up to Barry and have enjoyed the New 52 Flash. Having said that, Rebirth's moment of Barry embracing Wally and finally remembering him was one of my favorite moments in comics over the last decade, and I would probably say one of my favorite moments in 30 years of reading comic books.
I would easily give that moment back just so Wally wouldn't have come back and couldn't be used in HiC. This just sucks. There's no other way to put it.
