User blog comment:ImperiexSeed/Caitlin's statement in 2x17 "Flash Back"/@comment-3423279-20161014220058/@comment-3481504-20161015001359

If Caitlin was right about this, then there's nothing else going on, they all can only move their bodies as fast as Barry. They could've easily left this part out of the episode, and by adding it, they really diminished Zoom and the RF.
