The whole team travels to Earth Two (which is why they look so different and are getting cozy), and we get our very first real look at Caitlyn Snow’s (Danielle Panabaker) alter ego, Killer Frost!
Oh, and yes, the Reverse-Flash (Matt Letscher) is back too.
The Flash returns on Tuesday, January 19 @ 8PM on The CW!
WHAT DO YOU THINK of this new Earth Two promo for The Flash?
