In episode three, “Shalwar Kameez," we meet up with Carrie Mathison (Claire Danes) on her first day back working overseas. After successfully threatening CIA director Andrew Lockhart (Tracy Letts) with treason on the Season 4 premiere of "Homeland," Carrie arrived at the U.S. embassy in Islamabad, Pakistan, to begin her work as station chief. Back in the U.S., things were still shaky for CIA operative Peter Quinn (Rupert Friend) due to his involvement in the death of CIA chief Sandy Bachman’s (Corey Stoll). Here are the top five most dramatic moments from "Homeland” Season 4, episode 3:

Quinn’s feelings for Carrie revealed

Following his involvement in Sandy’s passing, Quinn visited Langley to discuss his desire to quit his job with the agency.  

“I just want out. I’m done,” Quinn said.

After operatives hinted that his romantic feelings for Carrie may be the reason for his requested leave, Quinn stormed out of the meeting. After repeatedly ignoring the CIA’s calls following his unsuccessful discussion at Langley, CIA agent Dar Adal (F. Murray Abraham) made a house call to Quinn’s motel abode and accused him of letting his feelings for Carrie override his professional duties.

“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 said.

Despite Quinn denying his feelings for Carrie, Dar claimed the whole agency was convinced that his love for her is what caused Sandy’s untimely demise. 

“You took your eyes off sandy to save Carrie. You left him to be beaten to death in the street!” Dar said, a comment which caused Quinn to lash out and choke him.

“Well done, Peter," Dar said after being released by Quinn. "I knew you weren’t that far gone ... Have a nice life." 

Carrie looked into Sandy’s past

After learning of Sandy’s alleged treason from former Islamabad case officer Jordan Harris (Adam Godley), Carrie revealed her suspicions about him to her new team at the embassy in Pakistan. Despite the U.S. embassy’s ambassador Martha Floyd’s (Laila Robins) refusal to lift the embassy's lockdown policy due to the recent outrage following the wedding bombing, Carrie remains vigilant in trying to uncover the truth about Sandy’s sources. After one of her team members challenged Carrie’s suspicions, claiming his intel was “good,” Carrie suggested Sandy's sources were possibly "too good."

“I mean how else was he getting exact targeting coordinates on the bad guys we’d lost track of for years? Nobody wants to admit the possibly that he was spying right under our noses … We have to reconstruct the events leading up to Sandy’s death,” Carrie said.

Carrie tricked Aayan

In spite of the embassy’s lockdown policy, Carrie formed a secondary team in Pakistan. The group, joined by Fara Sharazi (Nazanin Boniadi), planned to use her to seduce Aayan Ibrahim (Suraj Sharma), one of the few wedding bomber surviors, in order to gain possible intel. After Fara’s meeting with Aayan, under the guise of her being a British journalist, was widely unsuccessful, Carrie made her own plan to corner the Pakistani medical student whom she deemed a valuable source. 

While dining in a coffee shop, Aayan was recruited by a lcoal to help a supposedly ailing women in a public restroom. When he entered the facility, he was found facing Carrie who informed him she was a journalist. 

“You’re in trouble Aayan. You are part of an important story. I want to be the one to tell it,” Carrie said.

While Aayan originally expressed disinterest in helping the cause, Carrie’s promise to help remove him out of harmsway and into a medical school outside of Pakistan eventually peaked his interest.

“You will never see him again if you don’t want to but you should want to especially if you’re any kind of danger. Whatever you decide, I’m truly sorry for what happened to you and I wish you luck,” she said.

Carrie butted heads with Saul

Their joyous reunion at Sandy’s funeral back in the U.S. dissolved when Saul Berenson (Mandy Patinkin), the former CIA director, surprised Carrie at the U.S. embassy in Pakistan unannounced. 

“I’ve got enough on my plate without being responsible for the safety of the former director. Now that you’re hear it looks like I’ve reached out for help. It's not exactly the message I want to send,” Carrie said.

After Carrie denied needing Saul's, she soon after requested his assistance in removing the ambassador's embassy lockdown. Despite Saul’s success in helping convince Martha to eventually lift the ban, Carrie’s upset with Saul continued when she learned that the ambassador was his former fiancée. 

“Go home,” Carrie told Saul. After Saul revealed he is due to return to the U.S. the following day, he pointed out Carrie’s noticeable distance, a distance which she blamed her career.

“I’ve wanted to pick up the phone so many times but what I wanted to talk about I couldn’t. I still can’t,” Carrie said.

After giving Carrie some late-minute work-related advice, the duo parted ways, Saul telling Carrie, "Happy hunting."

Quinn made a shocking discovery

After rewatching Sandy’s death video on YouTube, Quinn discovered that the entire incident was not a coincidence, but instead, an act appeared to have been coordinated by Pakistani intelligence. 

“We never had a chance … in the car with Sandy. It was premeditated the whole thing from start to finish. There was a guy in a crowd with an earpiece coordinating the whole thing,” Quinn told Carrie.

Following Quinn’s discovery, Carrie requested him accompany her to investigate Sandy’s death in Pakistan. Despite his previous plans to ditch the CIA, Quinn begrundily agreed to assist her. 

“This changes everything. This means I really need you now,” Carrie said. “I wouldn’t ask you if there wasn’t someone else here I could count on. Don’t make me beg.”

“You’re the hardest person in the world to say no to,” Quinn said.

“God, I f—ing love you Quinn,” Carrie said. “You know that, don’t you?”
