Alex (Priyanka Chopra) will be tortured until she reveals the truth in the upcoming episode of "Quantico."

In the episode titled "LCFLUTTER," the promo reveals that the Citizens' Liberation Front will not show mercy until they get what they want. Last episode, Alex helped Lydia (Tracy Ifeachor) secure the computer drives that allegedly contain sensitive information for the extremists. When they got them from a vault, Lydia then turned on Alex and knocked her out. When she regained consciousness, Alex was tied up. Lydia told her she was CIA and she did not wish to destroy the drives. She then alerted the CLF so they could find Alex quickly.

In the trailer, Alex is shown being tortured by the group. Since she will not talk about where the computer drives are now - even though she is suffering a lot - her friends are brought one by one. Dayana (Pearl Thusi) is one of them. She is tortured in front of Alex until the latter spills her secret. In the clip, Alex is telling the other woman to be strong and withstand the pain. She does not wish to see her friend die, but she also does not want the CLF to get the drives. Will she withstand the torture until the end?

Meanwhile, the synopsis (as per CarterMatt) reveals that Owen (Blair Underwood) is planning another advanced training at The Farm. Last episode, he let the trainees decide whether a drone strike should be ordered to take out the terrorists. Alex and the others were unified in their decision when they decided "no." This time around, he will be training them on interrogation techniques. There is a twist though. He will be the one on the hot seat. Elsewhere, Shelby (Johanna Braddy) will go undercover to learn Leon's (Aarón Díaz) secrets.

"Quantico" season 2 airs Sundays at 10 p.m. EST on ABC.
