The underground task force risks everything in a mission that they might fail. Meanwhile, Shelby (Johanna Braddy) is caught in the middle of the Haas brothers — Clay (Hunter Parrish) and Caleb (Graham Rogers).

On the next episode of "Quantico" season 2, titled "MHORDER," the task force will be risking their lives to go out into the open on a mission to break the bond between the eight collaborators.

"With all the collaborators unveiled, the team uses Clay and Maxine's (Krysta Rodriguez) engagement party to entice them into one place. The mission: turn one against the others. But everyone's lives are put at risk when one member of the team makes a surprising decision," the episode listing on The Futon Critic reads.

However, it appears that the members of the task force will initially fail their mission. As seen from the episode 19 promo, Alex (Priyanka Chopra) tells her team, "They're playing us. We could all be walking into a trap."

Later on, a scared Ryan (Jake McLaughlin) says that the collaborators will kill each and everyone involved in the task force before he is seen fleeing the building with Alex. It is possible that one member of their group might switch sides at the last minute, which puts all of them in danger.

Meanwhile, Shelby is caught in a bad mess between Clay and Caleb.

Previously on "Quantico" season 2, Caleb warned Shelby that he will make her life "a living hell" if she doesn't stop whatever is going on between her and Clay. Given Shelby's history with Caleb and his dad, she will be making things worse by continuing to throw herself to Clay, who happens to be engaged to Maxine.

Will Shelby continue her secret relations with Clay?

"Quantico" season 2 airs every Monday night at 10 p.m. EDT on ABC.
