I think I would love to see Thawne take Barry's face. He did it to Wells. I doubt it will happen but it would give a nod to RF having reconstructive surgery to look like Barry. Also, putting on the costume would nod to Thawne traveling back in time and acting as Barry Allen along side Wally
IF ONLY! Now that would be a very special episode. What is The Flash's version of pink kryptonite? It needs to be introduced ASAP.
