Quantico returns on Sunday (10/9c, ABC). A drama about FBI trainees at the FBI Academy in Quantico, Virginia. One of them is a sleeper agent, who will engineer a major terror attack on the US.

The midseason premiere picks up three months later in the future timeline following the bombing at the FBI command center, which claimed 32 lives.Here are three things to expect on the mid season premiere.

Who died?

Of the 32 people killed in the bombing, one of them is someone we already know and with whom are very familiar. The person’s identity will be revealed in the opening minutes of the episode.

To expect nothing but the truth

The three-month time jump sets the stage for the congressional hearing about the bombing. Everyone believes Elias (Rick Cosnett) acted alone — except Alex (Priyanka Chopra), who is adamant that he was working for the real terrorist. But she has absolutely no evidence to prove it and is pressured to move on.

Where did Liam take Alex? Unfortunately, we don’t get a definitive answer yet, but you’ll get a clue that something definitely went down on New Year’s Eve.

New NATs

Well, technically they’re old NATs. At Quantico, Liam (Josh Hopkins) and Miranda (Aunjanue Ellis) bring in the class of trainees who had arrived at the academy a couple weeks earlier to face off with Alex & Co. in a Battle of the Classes Color War. The new faces, who are sticking around for the rest of the season, are Drew Perale (Lenny Platt), an ex-football player; Will Olsen (Jay Armstrong Johnson), an uber-smart rocket scientist; and Iris Chang (Li Jun Li), a former startup entrepreneur.

“We tried to bring in the new class actually a couple of times in the first half of the season,” Josh Safran, Executive Producer said to TV Guide . “It was just always on the docket because at actual Quantico, there are, I think it’s like 12 classes at all times. They’re [coming in] every two weeks, so you’re there with a thousand people basically. … And I wanted to bring them in. We just couldn’t [fit them in the first half] and then Ryan left, Simon left.”
