Spoiler: showSo theory we came up with at work. They've already said they plan to use Wally West, what if what Cisco said was right and there were 2 flashes there when Barrys mom gets killed, and the flash that saved Barry was Wally West. Also theory that Dr Wells is Eddies son/grandson etc from the future. And Eddie will turn into Hunter Zoloman at the end of the season after Barry steals Iris. But most of all, Flash Rings for everyone!!!!!
