So much to love here. Amanda Pays and John Wesley Shipp in the same episode was fantastic (bring on Hamill!). The Reverse Flash was such a badass, and that reveal at the end was something that...well, I think it was unexpected because it was so expected. Like Niltusk said, they have a way of twisting things 1,000,000 ways on The CW, and, while it could be that Wells isn't the Reverse Flash, there's a good chance it is. All that I can say, though, is damn...talk about playing the long con. Going back in time and killing his mother, I can see, but spending decades, in real time, becoming a respected scientist in order to be there when he's created...that's commitment. There's still a part of me that wonders if Wells isn't a future Barry, though. Maybe he was more akin to the Silver Age Flash, with no tragedy in his life, and, without that extra motivation, he failed to avert the "crisis (whatever theirs may be)," so he went back in order to make sure that he had something else to rush the process; sacrificing the thing you loved the most for the greater good. I doubt that would ever be the case and I could see about a billion and one plot holes in such a notion, but I'm thinking aloud here.
I wonder if it's not as clear cut as we don't want to think it is. Wells is Eobard Thawne, and the reason he didn't kill Eddie Thawne is because doing so would also undo his existence.
