Nikita's Dillon Casey Details the Life of a 'Dead' Sean, Why Resentment Toward Alex Is Inevitable

Nikita Season 2 SpoilersRIP Sean Pierce.

The CW’s Nikita (Fridays, 8/7c) last week shockingly “killed off” its stalwart Navy SEAL after Amanda framed him for a horrendous crime — but of course, he’s not really gone. Dillon Casey‘s crime-fighting alter ego has instead been forced into a full-time Division gig, living underground with a few rogue agents and Alex, the one (temporary?) bright spot in his turned-upside-down life.

Here, Casey reveals what the world of his “dead” agent consists of, why “Salex” is in for a slightly rocky road and why we may never see Sean’s funny side.

TVLINE | What does the life of a “dead” Sean look like?
We’re going to see more of him, that’s for sure. He’s part of the team now, whether he likes it or not. He was always a reluctant part, but now he’s in there and it’s official. He’s still injured — he shot himself at close range in the shoulder — so he’s not ready for action yet. His whole world has been turned upside-down; he’s not allowed to leave Division because he’s a known felon,plus he’s dead, so he can’t just show up in New York City. [Laughs] If he’s going to be useful at all, he’s going to have to do it from within the confines of Division. Right away, he’s really stir-crazy; he’s a high-energy guy who wants to be out in the field and part of the action. Now he’s fighting for an operation that he doesn’t really trust. So, his only point, really, is to try and embrace it and to do good within Division. He has to become a behind-the-scenes guy for a while, sort of the way Michael took a backseat after he lost his hand… He can help out as a General, in that sort of way.

TVLINE | Last week, Sean felt that he “died a criminal, a traitor” — will we see some residual effects of that being his mindset?
Of course. To become a Navy SEAL, they’re the best of the best in the world… He’s worked his whole life and suffered a huge amount to become a person who does the most amount of good that he can for America. And what happens? He dies a murderer and a traitor. [Laughs] He lost his mother, he lost his life, he lost his sisters. It’s horrible. But one of the things about his SEAL training is that you learn to accept a situation and move forward. Of course he’s going to have residual emotion, of course it’s in there, but he needs to decide whether to act on it… The whole goal of Division is — or should be — to shut down Division, to ultimately have this place not exist anymore. If they’re successful and he continues to keep his head down and take part in good missions, eventually maybe he’ll get his life back.

TVLINE | Will Sean blame Alex at all for his situation?
Sean’s very weary of combining his emotions for Alex with the action of the field. That’s why when he realized he was in the love with her, he needed her to leave; he couldn’t stay. So, I don’t know if he blames her. Whether he likes it or not, he does harbor some resentment toward her because he gave her the opportunity to leave and she didn’t take it. He’s given up a ton for her — he’s saved her life a number of times, he’s been there for her, he’s had her back — and if you actually look at it, she hasn’t given up anything for Sean. It’s a tough situation for him. He loves her. She asked him to meet her halfway, so at some point she’s going to have to cut him some slack and let him deal with the situation and help him through it for once.

TVLINE | Now that Sean’s a permanent fixture within Division, will we see any new dynamics develop within the team?
I love Sean’s interactions with Michael; there’s a nice chemistry there. You’ll see that Sean’s an all-around good guy — as much as he’s in this awful, awful situation, he knows that they’re all in the same boat. Owen he doesn’t care for; he doesn’t like the guy. [Laughs] There’s actually a huge episode [coming up] when Sean and Owen go out in the field for quite a long period of time and Alex is a burning topic that they might have to discuss. [Laughs]

TVLINE | Sean’s been pretty vocal about not agreeing with Division, and now Ryan wants to veer back into Percy territory. Will will see some head-butting on that issue?
From what I can tell, Sean has just put his head down and worked…. If they’re doing something he doesn’t agree with, he doesn’t have to take part in it. But the one thing on his list is to keep Alex safe and make sure she stays on the straight-and-narrow. She’s a bit of a nutty person, so it’s not that easy.

TVLINE | Sean is so serious and you’re so not. Any chance we’ll see a lighter side of the character this season?
My friends and family, especially my mom and dad, are always saying I should smile more…. [Laughs] So, I’ll do a scene and think [about that], but whenever I try to add a little humor to it, the director says, “Don’t do that,” or it gets cut out. I’ve definitely tried to add in a little of my own stuff here and there, but it’s tough because it’s just not being looked for in that character. There are moments where I’ll be the first to admit Sean’s been a bit of a schizophrenic character; he has times where he’s Mr. Badass, and there are times when he’s Mr. Goofball. But when he’s with Alex, the walls come down and he hams up a little for her. The humor, I feel, comes from Alex, the banter/trash-talking  he has with Michael and the jealousy he has with Owen. I would love it if there was more, but it’s a lot of stuff to pack into 45 minutes. [Laughs]
