Jay Garrick from Earth 2 comes to visit and stop the Sand Demon. Luckily, after the lackluster previous episode, Episode 2 is back on track to the usual awesome! The Flash of Two Worlds introduces the multiverse and sets up our main villain in flawless fashion! The two Flashes, Barry and Jay, have great chemistry with one another and make it a fun experience to kick off Season 2. Furthermore, it creates mystery better than Season 1 ever could. Who is Zoom? Jay? Wells? Patty? The world may never know...until Episode 15. I love 2x02 and it should've been the premiere for this season. Definitely going above the last at an 8.6/10.
