The CW's The Flash returned to screens last week and brought with it a great episode that laid the foundations for what could be a very troubling season ahead for Barry Allen's Scarlet Speedster. For this second episode of Season 2, Flash of Two Worlds, we have the comic book Golden Age Flash, Jay Garrick, stepping out of the shadows to warn Barry of an impending threat and to do his best to assist this world's Flash. That threat, of course, is Zoom; a dark and twisted speedster from an alternative world. With another villain-of-the-week brought in for Barry to tackle in this episode, we were also introduced to a few new faces, saw some problems arise for certain members of the S.T.A.R. Labs team, and were most impressively given our first real look at the 'big bad' who's set to cause havoc for The Flash throughout this season. As such, here's the pick of Flash of Two Worlds' WTF moments that had you in shock, in awe, or that just brought a warm fuzzy feeling to your inner comic book nerd.
