One lesson learned from Escape from Earth-2, as also demonstrated earlier in the season, is that Zoom can pretty much brutalize the Scarlet Speedster whenever he gets the urge. This time, Zoom brought back the phasing power and stepped inside Barrys holding cell before laying the smackdown on the Sultan of Speed. Again, The Flash proved to be not even close to being a match for the insane powers of Zoom. This was a stark reminder that this villainous speedster can f*ck up Barry Allen whenever he so chooses.
