After the explosive revelation of who the real terrorist is, more mysteries will begin to unfold when "Quantico" returns for the second half of the season.

In the breathtaking midseason finale, viewers discovered that Elias Harper (Rick Cosnett) was the real culprit behind one of the bloodiest terrorism acts in New York City. And after admitting that he was forced to frame Alex Parrish (Priyanka Chopra), he ended his own life by throwing himself out of the window.

Executive producer Joshua Safran explained Elias's involvement in the terrorism act in his recent interviews after the midseason finale.

"Elias definitely is a terrorist, but whether he is a pawn of a larger mastermind or whether he acted alone is going to form sort of an arc of episodes moving forward," Safran explained in an interview with TVLine. 

However, the danger in New York remains as another bomb threatens to blow up another part of the place. This means that Alex and the FBI need to find the other terrorists.

Speculations claim that another one of Alex's friends from the Quantico training facility is the one behind the new threat.

Caleb Haas's (Graham Rogers) mysterious trip to the first bombing site weeks before it exploded placed him on top of the suspect's list. But is he the real terrorist?

Safran chose not to answer the question, saying: "I cannot answer that, but of course, it is an interesting development that the bank that Mark Raymond is depositing his money in is the same bank that would come to be the emergency command center at a later date."

But fans of ABC's hit drama thriller will only find out the truth behind the next terrorism attack when the series returns on March 6, 2016.
