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

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

No official synopsis for the episode has been released, but it looks like Barry travels to the future to try and find out the identity of Savitar. Once in the future, he will come across a number of our favorite characters only to find them in places he never expected.

Just one question, why do we have to wait a month?
