"Quantico" Season 1 episode 10 will finally reveal Simon's (Tate Ellington) biggest secret.

ABC just dropped the synopsis for "Quantico" which revealed that one of the trainees will be cut out from the team. "An emergency disciplinary hearing at Quantico results in deep secrets being revealed," the first half of the synopsis reads.

In Season 1 episode 9, fans learned that Simon is close friends with a man who also creates bombs professionally. According to International Business Times, it is possible that Simon's relationship with the character will be revealed in the upcoming episode, and this could cost him his training.

In the flash forward scenes, it was revealed that Simon was thrown out of the program because of something that he did. Now, there's a huge chance that it could have something to do with the bomb. 

Meanwhile, "Quantico" will also focus on Alex (Priyanka Chopra) and her team trying to find the real bomber.

In other news, showrunner Josh Safran recently told Entertainment Weekly that more details about Simon will be revealed in episode 10. Unfortunately, he didn't say whether or not this would have something to do with him being thrown out of Quantico.

"This is a tipping point for his character, and you're gonna learn a lot more about Simon in the next episode. In fact, I might hasten to add that you will find out everything about Simon in the next episode," he said.

Meanwhile, Safran also weighed in on Sunday night's biggest twist. In "Guilty," Alex was able to gain back the trust of all of her friends from Quantico.

"Yes, everyone is Team Alex with the exception of Clayton. You'll find out in the next episode just what the FBI does and does not know about Liam and Alex's plan that transpires at the end of this episode," he said.

"Quantico" Season 1 airs Sundays at 9 p.m. ET on ABC.
