Quantico episode 4
Alex has only 24 hours left to find the real culpritABC

Quantico is entering the final phase of season 1 and fans are on the edge of their seats to know the real face behind the bombing of the Grand Central Terminal. Till now agent Alex Parrish was the prime suspect who was running away from the FBI in order to find the mastermind, who is one among the rookies who joined the academy, to protect the US from terrorists.

In the upcoming episode, another government group, HIG, will come to interrogate Alex and Ryan and ask her to investigate each of her friends to find the mastermind before the bomb explodes. The team has only 24 hours left to find the real culprit and it appears that Bollywood star Priyanka Chopra's character will finally locate him/her.

The official synopsis of episode 10 reads: At Quantico, an emergency disciplinary hearing causes deep secrets to be spilled, while in the future Alex works covertly with her team to find the real bomber before her time runs out.

In the previous episode, Caleb, Elias, Natalie and others tried to prove Alex's innocence by establishing a timeline. They conclude that their friend was drugged and kidnapped and then supposedly transported to the Grand Central Terminal before or after the bombing.

Simon Asher's role in the entire event is still suspicious and executive producer Josh Safran has hinted that a lot about his character will be revealed during the upcoming episode. "Simon's journey has always been such that he is repeatedly pushed to the side and sort of not given the credit he deserves, even though every time he proves himself, and yet at the first chance, people still push him away. This is a tipping point for his character, and you're gonna learn a lot more about Simon in the next episode," he told Entertainment Weekly.
