Alex might finally make some progress on her search for the terrorist on “Quantico” Season 1. Without the Voice calling her, the agent has to find another way to track down the bad guys. It seems reconnecting with Caleb may lead her to someone who knows everything in episode 19 of the ABC drama.

“Alex [Priyanka Chopra] continues to search for the terrorist, and in the process, discovers some familiar faces — including one who knows the terrorist’s endgame,” the synopsis teases. Who will the “familiar faces” be? Well, the guest stars for this episode are all recurring characters, so it’s hard to say which one has information on the bomber.

Among the former classmates Alex is working with is Shelby (Johanna Braddy). If Alex is willing to work with the southern belle, she must realize that Shelby was also being controlled by the terrorists when she drove the car that took Simon (Tate Ellington) and Will (Jay Armstrong Johnson) away. In the trailer for episode 19, titled “Fast,” Shelby says that she and Alex might be going on a suicide mission.

Of course, this episode will also show the present day timeline. Photos of a training exercise reveal that Iris (Li Jun Li) is still around. She couldn’t pass the security protocol in the last episode, but it doesn’t look like she was kicked out. She might even be thinking about her future with the FBI.

“It’s career day at Quantico as the NATS meet representatives from various FBI branches to help them decide their future paths,” the synopsis reveals. It sounds like their training is almost over, which makes sense because executive producer Joshua Safran revealed that audiences won’t see much more of the present day timeline after this installment.

“The end of the next episode, the very last moments pretty much — not pretty much — tell you directly what the rest of the season is going to be,” Safran told Entertainment Weekly. “From the very end of 19 on, we’re pretty much in real time in the New York storyline and the master plan is revealed.”

“Quantico” Season 1, episode 19 airs Sunday, April 24, at 10 p.m. EDT on ABC.
