Watch the Extended Promo for The Flash “The Once and Future Flash”

The extended promo for the next new episode of The Flash has been released. The episode is cslled, “The Once and Future Flash” and it will air on April 25.

What did everyone think of last night’s episode? I love the twist with Caitlin, but I hope they don’t make her permanately a villain. It would be cool if they found a way for her to be Killer Frost and good at the same time.
