After going undercover in episode 5, the NATs will learn the art of surveillance. In “Quantico” Season 1, episode 6, the FBI trainees will be tasked with keeping an eye on someone. However, according to the synopsis for "God," it’s not just a random assignment.

“The NATs learn surveillance by putting it into practice with Miranda and her troubled son, Charlie,” the synopsis reveals. Last time audiences saw Charlie (J. Mallory McCree), he told Miranda (Aunjanue Ellis) that he might be up for parole soon. If he’s under surveillance, it would seem that he finally got out. This isn’t good news for Miranda, who was the one to put her son in jail.

While the agents learn about Miranda’s personal life, they’ll also have their own troubles. Despite their hookup in episode 5, Shelby (Johanna Braddy) doesn’t want to get close to Caleb (Graham Rogers). She “tries to keep Caleb at a distance,” the summary says, but Raina (Yasmine Al Massri) takes the opposite approach with Simon (Tate Ellington). The twin “opens the door to a closer relationship with Simon,” but how will her sister Nimah (Yasmine Al Massri) feel about that?

Alex’s (Priyanka Chopra) romance with Ryan (Jake McLaughlin) isn’t mentioned, but the promo video reveals that it’ll definitely be explored in episode 6. Jake looks like he wants to tell his love interest about his secrets, but will the agent actually reveal that he was sent to spy on her?

As Alex’s man contemplates telling her the truth in the past, she’ll try to learn the truth about who is framing her in the flash-forwards. “In the future, Alex is helped when she tries to hack into an FBI computer,” the synopsis teases. So, who could lend a hand with such a dangerous mission? Viewers will have to tune in to see which former classmate steps in to help Alex next.

“Quantico” Season 1, episode 6 airs Sunday at 10 p.m. EST on ABC.
