'Quantico' Episode 8 Spoilers: Are Nimah & Raina Really Innocent? Actress Teases 'Suspicious' Future

The FBI gained the upper hand against the innocent agent on Sunday, and soon Alex (Priyanka Chopra) will find herself in an intense interrogation while Ryan's (Jake McLaughlin) life is on the line. In the past, Simon's (Tate Ellington) instincts will put him in dire straits when Anne Heche guest stars.

"At "Quantico," the NATS attend a class with guest speaker Dr. Susan Langdon, played by Anne Heche. Dr. Langdon is a former agent and profiler who tasks the trainees with looking at serial killer cases to find the one victim that doesn't fit the case, but when Simon becomes too good at finding things that don't belong, it's his life that becomes endangered," ABC teased. "In the future, Alex is interrogated by a highly sophisticated FBI team while Ryan's life hangs in the balance."
