Following the producer’s preview that debuted yesterday , The CW has released an extended trailer for the 19th episode of “The Flash,” which you can check out in the player below. Titled “Who is Harrison Wells?” the episode is officially described as follows:
“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.”
Wendey Stanzler directed the episode written by Ray Utarnachitt & Cortney Norris. “Who is Harrison Wells?” will air on April 21.
