It seems like Peter Quinn (Rupert Friend) could be a changed man when Showtime's Homeland returns for Season 4 in October.

Quinn "Concerned" for Carrie In Season 4 of Homeland

As TVLine notes in a new report, Quinn is still shaken up over some of the events that occurred in Season 3, including his having a hand in the death of an innocent kid in a Latin America mission. Though Quinn gets sucked back into the spy game in Season 4, he will try to prevent Carrie (Claire Danes) from getting too involved in the profession, which often results in needless death.

With Quinn trying to protect Carrie, there will be a certain level of closeness that forms between them. Homeland show runner Alex Gansa told TVLine, "[Carrie's] got a burgeoning relationship - although not romantic, yet - with Peter Quinn."

Homeland's Carrie Leaving Baby Behind In the U.S. Because "I Don't Have A Choice"

There is a new bio on the Showtime website for Quinn that teases his being pulled in by Carrie.

Though it says that he has "every intention of leaving the Agency for good," it all changes when Carrie "pulls him back in. But can his loyalty (and perhaps unrequited feelings) toward her bring him out of his PTSD funk and return him to the world-class agent he was, or will they drive him further to despair and self-destruction?"

Homeland Season 4 is slated to begin Sunday, Oct. 5 at 9 p.m. ET/PT on Showtime. The network is airing the first two episodes of the season back-to-back, ending at 11 p.m.
