I can't never remember which of the topics were being used for this one... so I'll just put it in a new one.
I guess this episode was a mid season finale of sorts.
I'm not up on my comic book lore, and even less when it comes to the Flash. I don't know what the Doctor is, if he's even a comic book character.
I'm not sure I fully understand what happened in the episode at the end there. The Reverse Flash is a remote controlled Wells robot? But that doesn't make sense to me at all. Wells doesn't make sense to me at all. Can't grasp what his game is.
