The Flash: New “Who Is Harrison Wells?” Footage Released

The CW has released the latest extended look at The Flash‘s next episode, “Who Is Harrison Wells?”

For people who’ve been watching the show, that answers should be easy: Eobard Thawne/The Reverse Flash—time displaced sociopath who stole the real Well’s identity several years ago. But for the Flash’s cast, those revelations are just coming to light. With Reverse Flash’s mystery unraveling, Cisco and Joe head to Starling City to unearth a corpse that could very-well be the real Harrison Wells’. And back in Central City, Barry has a difficult time convincing Caitlin that her mentor is indeed the Reverse Flash.

Check out the trailer below, which contains a few guest appearances from Starling City’s finest (well, after The Arrow).

“Who Is Harrison Wells?” airs on April 21 at 8:00 p.m. on The CW.
