'The Americans' Season 4 Spoilers: Will Keri Russell, Frank Langella Discover Gabriel's "Visceral Attack?" [WATCH]

The Season 3 finale of The Americans made its way on FX. With Season 4 already being planned, will undercover spy Elizabeth (Keri Russell) and Philip Jennings (Matthew Rhys), discover their handler, Gabriel (Frank Langella), has a "visceral attack" planned for them?

In our previous recap, Claudia (Margo Martindale) met with Gabriel (Frank Langella), telling him she still wanted to recruit Paige for the Center. Because she doesn't know who her family is, Elizabeth asks Paige to go with her to Russia and visit her dying grandmother. With his pretend marriage crumbling, Philip took off his hair piece, removed his glasses, and revealed his true self to Martha (Alison Wright).

In our recent recap, Philip had to kill and frame one of Martha's co-workers to make the FBI look away from her. After getting the fake defector arrested, Stan Beeman (Noah Emmerich) was given the go-ahead to continue his investigation against Oleg (Costa Ronin), but he is nowhere closer to saving Nina (Annet Mahendru). Elizabeth had a chance to say goodbye to her dying mother.

Before the end credits, Philip was able to tell his wife that he wanted to leave the spy business. Elizabeth was filled with hatred as President Reagan declared the Soviet Union an "evil empire." Unable to control herself, the teary-eyed Paige called Pastor Tim and confessed her parents weren't Americans; they're Russians.

In an interview with Deadline, co-showrunner Joel Fields reveals viewers will continue to see Gabriel in the fourth season, "Frank brings such instant depth and complexity to the part. You know that Gabriel loves Philip and Elizabeth. But you can also feel, on a visceral level, what he's been through as a Soviet. And if he needs them to do what they don't want to do, he's going to use everything in his power to make sure they do it."

Co-showrunner Joe Weisberg adds, "Frank just gives you the sense of history, the history of a man who's been through a lot, but also that particularly sad, deep, yearning history of Russia that, frankly, Tolstoy and Dostoevsky make one feel. It's just awesome to be able to write for him."
