Candice Patton Previews Challenges Are Ahead for Barry & Iris on Tonight's 'The Flash'

Barry and Iris will be getting over their biggest challenge yet on The Flash tonight.

Candice Patton teases that there will be a “little bit of tension” between them as Barry (Grant Gustin) becomes obsessed with DeVoe.

“Iris is going to be a little worried about how serious he’s taking this DeVoe character,” she shared with TVLine. “There’s a lot more than meets the eye with him and it kind of ends up driving Barry crazy, because he thinks he knows more about this guy, that he’s not all that he’s cracked up to be, or that he’s portraying himself to be. It pushes Barry to do some things that could possibly get him in trouble.”

Tonight will all be about Iris and Barry working together and her trying to stop him from obsessing.

“I think she thinks, ‘Barry, you’ve got to take a step back, or you could end up in a lot of trouble. You can’t go after people like that. There are laws and rules,’” Candice says.

The Flash airs TONIGHT @ 8PM ET/PT on The CW.
