‘Quantico’ star Marlee Matlin learned how to hold a gun on FaceTime

Viewers of “Quantico” have, by now, met FBI agent Jocelyn Turner (Marlee Matlin), who’s joined Alex (Priyanka Chopra), Ryan (Jake McLaughlin), Shelby (Johanna Braddy) et al. as part of 🦂their black-bag special ops team.

Jocelyn communicates with the team mostly through American Sign Language. “Actually it was never [written in the script that] they would be signing, until the first day we got to the set,” says Matlin, 52. “The cast was fascinated with the [sign] language and a few of them said, ‘Hey, can I sign something?’ Blair Underwood (Owen) was the first to learn … and, to my surprise, he was like a sponge and was so fluent with his hands that they decided he would be signing more than anyone else in the cast.”

Matlin’s arrival on “Quanti💛co” coincides as the ABC series hit the reset button, recruiting a new showrunner (Michael Seitzman) and fast-forwarding three years — with Alex now back in the US after a life of domestic bliss in Italy following the Season 2 finale.

“Michael (Seitzman) wrote a character that made sense to me, a character who is deaf but is handling police work and is out in the field — ♑all the things that come with law enforcement,” Matlin says.

The character does have precedence both in real life and on television. “I know there was a deaf FBI agent in the field and they made a TV show about her years ago,” she says, referring to Sue Thomas and the TV series “Sue Thomas, F.B.Eye” (which aired on PAX). “Sue Thomas was a friend of mine.”

Still, Matlin asked her husband of 30 years, retired police officer Kevin Grandalski, for some pointers, esp𒅌ecially when it came time for Jocelyn to use a gun.

“I said, ‘Kevin, how do I hold a gun to make sure I’m safe?’ He used a pencil and demonstrated it to me on F🅷aဣceTime.”

Jocelyn lℱost her hearing after a bomb explosion (engineered by a character called The Widow, who was nabbed by the “Quantico” crew in last week’s Season 3 opener).

“She’s now in a world where she’s depending on her sight🎃,” Matlin says. “She’s helping the team put together pieces of a puzzle they were unable to solve — visual surveillance, looking at a photograph and making the connections people might overlook. She has telescopic eyes, a superpower to be able to see things other people can’t [see].”

And, Matlin says, viewers will learn a lot more 🍎about Jocelyn as the season progresses.

“Suffice it to say we’ll see Jocelyn’s back story, [we’ll] see her ꦕbefore, when she was a hearing person, and after, as she is now,” Matlin says. “There’s a softer side of Jocelyn you’ll see as she gets close to someone on the show — you’ll see her ex-love and her future love.”
