Sunday, 9 p.m., TNT

The “Claws” are cracked heading into the show’s Season 1 finale.

“You gotta keep your eyes open because everybody on this show is not who they say,” said Niecy Nash (“Getting On,” “Reno 911!”) of Sunday’s closer, which reveals a jaw-dropping twist in its final seconds. “It will set Season 2 off in a whole other direction.”

The TNT show follows a Florida nail salon owner named Desna, played by Nash, who takes up money laundering for Dixie drug kingpin Uncle Daddy (Dean Norris) after being wooed by his nephew, Roller (Jack Kesy). But she catches him hooking up with her employee, Virginia (Karrueche Tran), who shoots and presumably kills him. The two women then set his body adrift on a swamp in a burning boat. In a soap-worthy twist, Roller resurfaces, very much alive, and exacts revenge. In last Sunday’s episode, Desna was shaken to the core after Roller aimed a gun at her, just inches from her face.

Nash, 47, spoke with The Post about Desna and Roller’s sick relationship, and how her own mother’s shooting by an ex-boyfriend (which she survived) affects Nash to this day.

You nail Desna’s desperation in the scene where Roller aims his gun at her. How difficult was it to film that?
It’s always challenging when somebody pulls a gun on me [in a scene]. I saw my mother get shot when I was 15, so I have to double- and triple-check the gun and make sure it’s empty. Then I try to manage my real feelings about it because if that’s not where the character is, then I don’t need to be ahead of her — you know what I mean?

Does Desna regret ever being with Roller?
I would say so. It started off as a relationship of convenience. He was like a Mr. Fix-it — a utility lover. While she was able to make some money, it has caused a lot of damage, not just for her but other people as well.

What do you think worries her the most?
In the finale, you find her not only fighting for her life, but somebody else’s life is on the line now. I’m not gonna tell you who, but she’s fighting for that person as well.

What do you think of Desna’s flashy, form-fitting clothing and big hair?
I’m used to the skintight world. Desna dresses like a superhero in a lot of ways; that’s kind of how I dress. I fought very hard for her aesthetic. They wanted me to have a soccer- mom bob with blond highlights. I was like, “Absolutely not!” It felt so false. I wanted her wild and untamed.

The cast seems so cohesive. How did you bond?
I was the first actor to come aboard the project, and as each girl was added I dated them all separately. Being in New Orleans, you bond over a good meal. The thing that makes the chemistry work on-camera is that it really works off-camera.
