During the Television Critics Association press tour in January, series co-creator Howard Gordon revealed (via The Hollywood Reporter) that there is a good chance to see Quinn (Rupert Friend) back in the upcoming season.

"The way we're thinking about bringing him back — if he does come back — is really exciting to me personally," Gordon revealed.

Showtime CEO Gary Levine had previously teased the possible return of Friend's character to the critically acclaimed espionage drama series, saying: "Quinn is severely damaged — there is no question about it. The life or death question remains. If he should live, it will not be in any way, shape or form the way he has lived to date."

Series co-creator Alex Gansa, meanwhile, revealed that CIA black ops director Dar Adal (F. Murray Abraham) is also expected to be back in "Homeland" season 6 after the developments that happened in the finale of the previous season.

"If you remember that scene in the Dec. 6 episode, after the video comes out of Quinn in the gas chamber, you witness the emotion on Dar's face," Gansa said in an interview with the New York Times. "He has been such a stolid, unemotional character, and his relationship with Quinn mirrors Saul's relationship with Carrie. You can see in that moment how affected he is by what happened to Quinn, and you will see more of that as this season moves forward."

Other speculations about the upcoming plot of "Homeland" season 6 claimed that it will center on a topic similar to the September 11 tragedy in New York. This came up after reports revealed that the series will be set in New York City in season 6.

More details about "Homeland" season 6 are expected to come out soon.
