Everything is different for Carrie Mathison (Claire Danes) in season five of Showtime's "Homeland."

The new season picks up two years after the end of season four and finds Carrie working for a private security firm in Berlin. "Carrie really isn't an intelligence officer this season," executive producer Alex Gansa tells TVGuide.com. "She's definitely rejected her past. She is trying to find a way to forgive herself for all the stuff that she's done throughout her career, and she's begun to question if any of it made any difference at all -- whether she made any significant difference in the world. We actually find her doing something almost 180 degrees opposite to what she was doing in the CIA."

Carrie has also flipped the script in her personal life. Season five will find her raising her daughter with her new attorney boyfriend Jonas Happich (Alexander Fehling). "She has also been released from a false worldview of herself," Gansa said. "Her mother told her at the end of last season, 'Have a relationship! Your illness isn't keeping you from that.' So, we do find her in a very domestic arrangement with a guy, and that gives a whole different flavor to the season."

Fans of the show may be disappointed to hear that the domestic arrangement isn't with Quinn (Rupert Friend) who expressed his feelings for Carrie at the end of last season in a particularly touching scene.

"She hasn't been released from her false worldview at that point," Gansa explained. "Relationships are all about timing, and the timing was just 12 hours off."

But that doesn't mean that Quinn is trying to win Carrie back. Quite the opposite actually as it sounds like Quinn's character has taken a turn for the worse. "Quinn will be a different character this year. He spent a couple years down in Syria and Iraq leading a Special Forces team. You can imagine the stuff he's seen and how that might affect him."

"Homeland" will return to Showtime on Sunday, Oct. 4.
