In "Go," the previous episode of "Quantico," the new agent trainees (NATs) continued with their training and also received their first ever exam.

Quantico mentor Miranda (Aunjanue Ellis) handed the NATs their test paper and a pencil and left the room. To their surprise, the trainees found that the paper had nothing on it. But Alex (Priyanka Chopra) started to think that it was a piece of evidence that they need to work on.

They discovered that there were only 60 pieces of paper when there were 61 of them. Ultimately, they found out that Brandon Fletcher (Jacob Artist), who's supposed to be with the group, did not participate in the test.

Then the door lock was busted, locking the trainees inside the room with a broken air conditioning unit just when Brandon left. This means the NATs should figure out a way to get out.

When all the panic and adrenaline set in, it was later revealed that everything was just a test. Many of the NATs passed it with flying colors, but Elias (Rick Cosnett) didn't and had to leave the academy.

Meanwhile, in the present-day, fans of "Quantico" were glued to the screen as they watched their favorite Alex framed for the bombing that happened at Grand Central Station. Chopra's character continued to look for clues that should help clear her bad reputation.

She, together with Simon (Tate Ellington), discovered that one of the twins was spotted in the station before the bombing occurred. The two eventually found Raina (Yasmine Al Massri) and asked her for some answers, but what they discovered is that it wasn't her at the station, but her twin, Nimah.

In the next episode of "Quantico," another terrorist attack may be happening. While agents are busy trying to figure out who's behind the first attack, there could be another one waiting to happen.

The problem with that is it's the presumed guilty Alex who made the conclusion, and she might have to find different ways to convince the FBI of the imminent attack.

"Quantico" will return with a new episode titled "Over" on Sunday, Nov. 15, at 10 p.m. EST on ABC.
