Quinn (Rupert Friend) will try to help Carrie (Claire Danes) stay on the side of good in upcoming episodes of Showtime's Homeland, despite her new job as a "drone queen."

Homeland's Carrie Becomes 'Drone Queen' To Cope With Death Of Brody In Season 4

The toll of working in the CIA has weighed heavily on Quinn between Season 3 and Season 4, which was evident in Sunday night's premiere. With Carrie operating as the new Station Chief in the Middle East, Quinn will try to reel her in and prevent her from becoming too much of a killer with no emotion.

"Quinn has made a living killing people for awhile, he understands the toll it's taken on him. He's a lot further down the road of awareness than Carrie is -- she's kind of a newbie at this," show runner Alex Gansa says in a new interview with Entertainment Weekly. "He sees the warning signs and is concerned about her and is going to do everything he can to prevent her from crossing over to a dark side you can't come back from. The dynamic between Quinn and Carrie will be driving a lot of the story this season."

Quinn also demonstrated some "open-mindedness" in the Season 4 premiere as he had sex with his overweight apartment manager. Their relations will move beyond carnal as it carries over into the next episode.

"It's an unlikely duo, and it speaks to Quinn's need to comfort after what happened and his open-mindedness about who's a suitable partner," Gansa says. "You'll see as we move into episode 3 that the relationship deepens."

With Carrie almost drowning her baby (intentionally) and all of the drama in the Middle East, Quinn might prove to be one of the few likable and rootable characters still left on the series.

Homeland Season 4 airs Sundays at 9 p.m. ET/PT on Showtime.
