So long, Aayan. After several episodes of Carrie Mathison (Claire Danes) recruiting drone strike survivor and terrorist Haissam Haqqani’s nephew Aayan Ibrahim (Suraj Sharma), the Islamabad station chief’s main source met his untimely demise in Season 4 episode 6 of "Homeland."

At the beginning of “From A to B and Back Again,” Aayan was planning to start his new life in London as a medical student under the name Badar Jalali. After Carrie told him he was ready to cross the Pakistan border, his last minute trip to his college dorm to collect his belongings turned his entire plan upside down after he was visited by a presumed member of the ISI. 

“This time there are no limits. You will end up at the bottom of a hole, or worse,” Carrie said to Aayan after he informed her of his surprise guest. Despite Carrie’s warning to him to push back his departure, Aayan refused, claiming his uncle could help his safely flee the country.

“If there's a problem, he can get me across the border. He paid for my college. He wants a life for me. He will help,” Aayan said. Appearing pleased with his plan, Carrie handed Aayan his new passport.

Shortly after agreeing to his proposal, Carrie and Aayan were attacked inside their safe house by several men. Just like Aayan was able to evade the mystery man on campus, he was also able to escape the team of individuals. Carrie, on the other hand, was not so lucky. Aayan idly watched as she was thrown into a van with their attackers. Thankfully for the station chief, the kidnapping was discovered to be her doing, a plan concocted in order to break away from Aayan in his quest to track down Haqqani. Carrie told the men, U.S. embassy workers, that they would be able to follow Aayan through a tracker she put in his passport.

“[Let’s] cross our fingers, see where he goes,” Carrie said.

Back at the embassy, Carrie’s plan was in full motion with the CIA watching Aayan’s every move. In route to Haqqani’s training camp, Aayan stopped and made plans to meet his uncle before calling Carrie to confess his true feelings for her. 

“You saved me not once, many times and I just, I need you to know that I love you and I can’t wait to see you again,” Aayan said. Despite begin in a room full of her colleagues, Carrie also shared her feelings. “I love you, too,” she said.

After Aayan’s emotional reveal, Carrie appeared conflicted about his inclusion in the deadly plot to track and kill Haqqani, but continued with her mission. Unfortunately for Aayan, his uncle, whom he was helping keep alive with stolen medications, had other plans for him. Just as Carrie and her team were about to kill Haqqani via a drone strike, Haqqani surprised everyone by taking Saul Berenson (Mandy Patinkin), who was kidnapped by Farhad Gazi in episode 5, out of his vehicle. 

“This was the director of the CIA,” Haqqani told Aayan. “The head of the snake that bombs us."

While Aayan was unaware of Carrie’s affiliation with the CIA, believing her to be a journalist during their tryst, Haqqani was well-aware of her true intentions with his nephew. 

“Your friend who sent you here… She’s his friend, his child practically … There’s a drone overhead right now sent to kill me. You’ve put me in a terrible place,” Haqqani said. “You saved my life with your medicines. Don’t think I’m not grateful” he added, before putting a bullet into Aayan’s head. 

“Take the shot! We’re losing our window!” Carrie said to her team after Aayan’s murder despite Saul also being present. “Take the shot goddammit. Wipe that f—er out!” she screamed. 

Peter Quinn (Rupert Friend) disagreed, telling Carrie’s team not heed her demands. “That is the ex director of the CIA, do not shoot,” he said.

“Are you out of your mind? That is Saul down there. Saul,” Quinn told Carrie.

After Aayan’s death and her second unsuccessful attempt at killing Haqqani, Carrie returned to her office and broke down into tears. 

The next episode of “Homeland” airs Sunday at 9 p.m. EST on Showtime.
