Watch the Promo for The Flash “Who is Harrison Wells”

The promo for the next all new episode of The Flash has been released. The episode is called, “Who Is Harrison Wells” and will air next Tuesday, April 21.

In the episode, “Joe (Jesse L. Martin) and Cisco (Carlos Valdes) head to Starling City to continue their investigation of Dr. Wells (Tom Cavanagh). While in town, the duo enlists the help of Captain Lance (guest star Paul Blackthorne), and Cisco meets the Black Canary (guest star Katie Cassidy), who asks him for a favor.

Meanwhile, back in Central City, Barry (Grant Gustin) races to catch a meta-human named Hannibal Bates (guest star Martin Novotny) who can transform himself into every person he touches – which includes Eddie (Rick Cosnett), Iris (Candice Patton), Caitlin (Danielle Panabaker) and even The Flash.”

I can’t wait to see Laurel and Captain Lance interacting with The Flash cast. What did everyone think of tonight’s episode?

UPDATE: We have added the extended promo above!
