'Homeland' returns in its fourth season with Episode 4 titled "Iron in the Fire" on Sunday, Oct. 19 at 9:00 pm on Showtime.

Previously Season 4 Episode 2 showed Carrie Mathison (Claire Danes) going back as the head of the dangerous CIA headquarters in Islamabad in Pakistan, without Peter Quinn (Rupert Friend) alongside.

Meanwhile, Episode 3 showed a turnaround as Quinn will reportedly finally reveal his true feelings for Mathison.

TVLine reports that Quinn ignored his responsibilities in the CIA forcing CIA agent Dar Adal (F. Murray Abraham) to intervene.

In a dramatic turn of events, Quinn discovered that Sandy Beckham's (Corey Stoll) death was conspired by the Pakistani intelligence while watching his death video on YouTube.

"We both know the real explanation or this. This isn't about PTSD, this is about your feelings for Carrie Mathison. If she hadn't been in that car, Sandy Beckham would have been alive today," Dar explained.

Meanwhile, Episode 4 of 'Homeland' is also likely to be as intense as the third episode.

Hollywood Hills revealed three new spoiler clips of the fourth episode named "Iron in the Fire."

The fourth episode will show Mathison receiving a tip, Fara uncovering a conspiracy, and Saul will accept a mysterious favor.

The upcoming episode will also feature guest star Nazanin Boniadi will play Fara Sharazi.
