Fair play, you have to give Harry Wells some props for his honesty here. With Barry having been noticeably slower during his battle with Tar Pit, Wells, with no real prompting, openly admits to having fitted the Scarlet Speedsters suit with a device that sapped some of his speed. It was a major WTF moment for audiences and for Team Flash, with nobody expecting Wells to come out with that reveal. Of course, this honesty went down like a lead balloon as Wells soon found himself locked up in one of S.T.A.R. Labs ever-convenient holding cells.
