The CW has now released some preview images for “Back To Normal,” the Tuesday, April 26 episode of The Flash.

In the episode, a meta-human with super strength named Griffin Grey (guest star Haig Sutherland) mistakes Harry (Tom Cavanagh) for Earth-1 Harrison Wells and kidnaps him, demanding that Wells cure him from his current condition. Realizing another brilliant Wells could help track Griffin’s location, Barry asks Jesse (guest star Violett Beane) to help. Meanwhile, Wally (Keiynan Lonsdale) corners Joe (Jesse L. Martin) about The Flash.

The Flash returns with new episodes April 19 — you can see photos from that episode “Versus Zoom” here. Photos from “Back To Normal” can be found below.
