Notice how the Reverse-Flash that Barry faced in the episode had lenses over his eyes, like Hunter Zolomon. On the other hand, the suit that Wells was looking at didn't have lenses over the eyes, like Professor Zoom.

This lends credence to the theory that the Reverse-Flash that killed Barry's mother is a future version Eddie, who like Hunter Zolomon in the comics, is out to hurt Barry; while Professor Zoom (Wells) has much grander plans in store.
