Spoiler:
I don't understand the significance of the ring or why it seemed to control the yellow suit or even change its color. It looks a lot like Barry's suit but if it is capable of changing colors and being remote controlled (or acting independenly?) at Flash speeds then the similarity between the suits must be only superficial. Anyway, it really looked like there was someone in the suit during the fights so I can't see how Wells could have pulled it off by himself. But are we meant to take it that this was all a ploy by Wells to take the device without suspicion falling on him?
I am starting to think Eddie is the most sympathetic character in the show. He keeps being set up as Barry's opponent in all sorts of things but he's actually a pretty nice guy, risks his carrier to go after a clearly dangerous vigilante (which seems entirely reasonable and I wonder why no one else is doing it) and he's being lied to by his partner for no good reason. I hope they don't make him turn evil when he eventually uncovers Barry's identity.
