CW's 'The Flash' Ep 19 Spoilers: Will Grant Gustin's Barry Allen "Break" Candice Patton Iris West's Heart? [WATCH]

Major revelations take place in Episode 19 of The Flash on the CW network. As the identity of Harrison Wells (Tom Cavanagh) and The Reverse-Flash comes into question, will Barry Allen (Grant Gustin) watch his friends fall apart and find Iris West (Candice Patton) "heartbroken" in the aftermath?

In our previous recap, The Flash found himself with a bomb strapped to his wrist thanks to the Trickster (Mark Hamill). In the flashbacks, the Reverse-Flash revealed himself to be Eobard Thawne (Matt Letscher), a murderer displaced in time. After causing a car crash, Thawne took possession of Harrison Wells' body and killed the original host. Realizing Iris was snooping around Mason Bridge's disappearance, the scarlet speedster revealed his secret identity to Eddie Thawne (Rick Cosnett).

In our recent recap, Felicity (Emily Bett Rickards) and Ray Palmer (Brandon Routh) helped out the scarlet speedster against Brie Larvan (Emily Kinney), the Bug-Eyed Bandit. While Iris and Eddie's relationship is on the rocks, Barry revealed his suspicions about Wells to Caitlin Snow (Danielle Panabaker) and Cisco (Carlos Valdes). With memories from the alternate timeline, Cisco has been having nightmares, reliving his death at the hands of Harrison Wells.

In an interview with Blastr, Patton reveals Iris will make a shocking discovery about Eddie, Barry and Joe (Jesse L. Martin), "She's going to be pissed! How can she not be? When that moment happens, Iris will be so justified in being angry. She's a happy-go-lucky kind of girl, so it will be nice to see her expel all of these feelings on Joe and Barry about lying. This is her father and best friend. Joe, Barry and Eddie are really the only men in her life, and those are the people she trusts, so for them to be lying about something that's so huge -- she's going to be disappointed and heartbroken."

Panabaker also reveals in the joint interview that Caitlin will find her loyalty tested, "She's an incredibly loyal person, and she came back to work for Dr. Wells after the particle accelerator exploded. What that took, how much faith she had to have in him to come back after that -- so he's on the highest possible pedestal. Anything to suggest It would be devastating, to have that reality crumble in front of her. She's not going to want to hear it, for sure."

The Flash continues Tuesdays at 8pm on the CW.
