In episode 18 of the CW's “The Flash," Barry (Grant Gustin) had some help from Felicity (Emily Bett Rickards) and Ray (Brandon Routh) from "Arrow" in stopping Brie Larvan (Emily Kinney) and her deadly robotic bees. Well, Barry will need all the help he can get in episode 19, titled "Who is Harrison Wells?" It looks like the superhero is gearing up to finally confront Dr. Wells (Tom Cavanaugh) about his Reverse Flash identity.

According to the synopsis for the episode, there will be more crossover fun as Joe (Jesse Martin) and Cisco (Carlos Valdes) travel to Starling City to recruit Captain Quentin Lance (Paul Blackthorne) for their investigation of Dr. Wells. Plus, Barry will have to contend with a new enemy, Hannibal Bates (Martin Novotny), who can change his appearance to look like anyone he touches.

However, the promo for the episode previews what fans really want to see – Barry confronting Dr. Wells. The teaser shows Barry visitng the scene of the car accident where Eobard Thawne (Matt Letscher) killed Wells’ fiancé and took control of his body. It appears that Joe and Barry will find the real Wells’ deceased body – the proof Barry needs to finally tell Caitlin (Danielle Panabaker) and Cisco the truth about their boss. What will happen, though, when Barry reveals what he knows to the scientist himself?
