A “Harbinger” of things to come, or a visit to Earth 2? Or both?
The CW has released a trailer for the second half of The Flash’s second season. It features Killer Frost, The Reverse Flash (actor Matt Letcher, who we learned will be coming back to the show), and what seems to be a version of Iris West staking claim on Barry Allen. The promo is titled “Everything Will Change”.
The Flash returns with all new episodes on January 18.
