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.
