In The Man In The Yellow Suit (S01E09),
Kill Eddie? We've been shown that Wells is in fact Reverse-Flash in this continuity. So why wouldn't he kill Eddie instead of leaving him alone?
EDIT: Thanks for all the answers, but seeing as how the question was asked before we learned the true identity of Wells and it was answered by the episode itself, I'm only going to upvote answers that provided a theory or answer that made sense or correctly guessed what was going to happen.
