The FBI agents on “Quantico” are always moving on to the next mission, but Alex will actually have a moment to look back on some of the tragic events of Season 1 soon. In Season 2, episode 6, she’ll remember someone she lost last year.

“At the Farm, the trainees learn their next task is to decide on a drone strike, which triggers Alex’s memories of Simon’s sacrifice,” the synopsis reveals. Simon (Tate Ellington) died while driving a nuke into the ocean to save his friends and the country. Alex (Priyanka Chopra) will have to keep herself together while she participates in this exercise.

It’s not going to get any easier for her, though. On top of any emotional scars she has to deal with, there is also the Harry Doyle (Russell Tovey) situation. In the last episode, he revealed himself as an MI-6 agent who is legitimately in the U.S. for FBI training in some sort of exchange program. The Brit knows Alex and Ryan (Jake McLaughlin) are FBI, and he demanded answers from the duo. However, they might not share much. “Nimah [Yasmine Al Massri] advises Alex and Ryan not to trust Harry,” the synopsis says.

Leon (Aaron Diaz) gets close to an FBI agent in “Quantico” Season 2, episode 6.

It won’t just be the field agents getting into trouble. It sounds like Shelby (Johanna Braddy) is getting into a forbidden romance. “Meanwhile, Shelby and Leon’s [Aaron Diaz] relationship reaches the next level,” the synopsis reveals.

As previously reported, Braddy told International Business Times that her new relationship would be more mature. “There’s definitely a new romance, yes, and it’s a completely different type of relationship than Caleb,” Braddy said. “It’s very different. It’s not so youthful.”

In the future, Alex doesn’t have anyone to advise her about who she can rely on. “Alex questions if she can trust Lydia [Tracy Ifeachor], leading to combat between the two,” the episode 6 summary reveals. Watch Alex confront her former teacher in the episode 6 promo video below:

Episode 6 is title “Aquiline.” All of the Season 2 episode titles are CIA cryptonyms, but this one isn’t complicated. Aquiline was an “aerial reconnaissance program” in the early 1960s, according to the Washington Post. It was all about drones, which makes sense with this week’s lesson.

“Quantico” Season 2, episode 6 airs Sunday, Nov. 6 at 10 p.m. EDT on ABC.

Lydia (Tracy Ifeachor) and Owen (Blair Underwood) teach their students about drones in “Quantico” Season 2, episode 6. Ryan (Jake McLaughlin) and Alex (Priyanka Chopra) need to decide who they can trust in “Quantico” Season 2, episode 6. Alex (Priyanka Chopra) must handle a lesson that brings up difficult emotions in “Quantico” Season 2, episode 6.
