Who Is Quantico's Elusive Bomber? Join Our Ongoing Investigation

Look sharp, NATs: Your next assignment is a crucial one.

If you’ve been following ABC’s Quantico, you know thatthe person responsible for blowing up New York’s Grand Central Terminal is somehow connected to recent graduates of the FBI academy— and that rookie Agent Alex Parrish is Suspect Number 1, though she claims she’s being framed.

As the Sunday-night drama has made us very aware, it’s often very hard to distinguish between truth and lies. And when you consider that every member of Alex’s class (including Agent Parrish herself) has been trained to deceive when necessary, the job of finding the Grand Central bomber becomes an even bigger — and more important — mission.

Is Alex being framed, as she claims? If so, who’s involved in the deception? What’s his/her/their motive? And how far up the Bureau’s chain of command do the lies go?

That’s where you come in. Based on what we’ve seen so far, we’ve assembled dossiers on the most likely suspects, starting with Alex herself. Click through the gallery below to absorb all the intel on her classmates and superiors, then hit the comments with your thoughts on who might be behind the crippling terrorist act.

We’ll be updating everyone’s file as the season progresses, so make sure to bookmark this page and return every week!
