The fourth season of Showtime's hit show "Homeland" will be premiering this fall, and showrunner Alex Gansa has recently enlightened the viewers on where the show is headed.

Warning: Spoilers ahead. If you have not seen or completed the second season, it's best if you stop reading now.

Season four is expected to do a huge overhaul. In season three, we saw the shocking demise of Brody (Damian Lewis), who was publicly executed in Iraq. Before he died, he found out that Carrie (Claire Danes) is pregnant with his child.

Showrunner Alex Gansa discussed in an interview with Entertainment Weekly on where he and the show producers are intending to take the show. He said, "There's so many new roles to be cast, it's like doing another pilot-which is exciting and terrifying at same time."

Gansa said that the upcoming season will focus on Carrie, and will focus on how she does the job she was trained to do. He added, "We're going to see what an intelligence officer does on the ground. How she recruits assets, how she deals with the foreign government and her country team - the people she works with in the embassy - and the host country's intelligence services."

The future of The Brodys--Jessica (Morena Baccarin) and Dana (Morgan Saylor)-- on Season 4 is reportedly bleak, but Gansa explained that they are only halfway through with breaking the show's episodes, hinting that there is a possibility that two might make it this season after all.

We also still do not know much about the events that will transpire in Season 4, but the recently-released titles for the first three episodes could give hints. According to Spoiler TV, episode one is entitled "The Drone Queen," episode 2 is "Trylon and Perisphere," and episode three will be called "Shalwar Kameez."

The fourth season of "Homeland" will debut on October 5, Sunday, at 9pm.
