Season four In "
Iron in the Fire", high-ranking Pakistani ISI agent Tasneem Qureishi approaches Dennis Boyd (
Mark Moses), the husband of US ambassador Martha Boyd (
Laila Robins), with a proposition. Tasneem is aware that Dennis stole top secret information directly from his wife and passed it along to the recently murdered CIA chief of station in Pakistan. She wants Dennis to continue procuring intel, but for the ISI instead. Spooked, Dennis tries to return to the US, but Tasneem threatens to expose him to the
Federal Bureau of Investigation (FBI), thereby sending him to prison for treason and ruining his wife's career. Meanwhile,
Carrie Mathison (
Claire Danes), the new CIA chief of station in Pakistan, learns that ISI agent Farhad Ghazi () was involved in her predecessor's murder. In "
About a Boy", Tasneem confers with ISI colonel Aasar Khan (
Raza Jaffrey) to compare notes on Carrie and her CIA mentor
Saul Berenson (
Mandy Patinkin). Intent on learning more about Carrie, including how she is able to come and go from the embassy unobserved, Tasneem gives Dennis a key to Carrie's apartment, but he cannot bring himself to break in. Before Carrie and her team can do anything about Ghazi, he drugs and abducts Saul on Tasneem's orders. Tasneem arrives just in time to prevent Dennis from confessing their arrangement to John Redmond (
Michael O'Keefe), the CIA deputy station chief. A disparaging comment from Martha prompts Dennis to do Tasneem's bidding and enter Carrie's apartment, where he photographs various items, including her family photos and medication bottles. In "
From A to B and Back Again", Dennis discovers that Aayan Ibrahim (
Suraj Sharma), the nephew of
Taliban commander
Haissam Haqqani (
Numan Acar), has recently been in Carrie's CIA safehouse. Dennis informs Tasneem, and gives her the photos of Carrie's apartment, noting that based on her medication she probably has
bipolar disorder. Tasneem tells Dennis he has "a real gift" for spying. Carrie uses Aayan to locate Haqqani, but Tasneem has warned Haqqani that his nephew has been compromised. Haqqani kills Aayan, and Carrie's attempt to capture or kill the Taliban commander is foiled when Saul is revealed as Haqqani's prisoner. In "
Redux", Tasneem gives Dennis some unidentified pills, which he places in Carrie's apartment in place of the
Clozapine she takes for her bipolar disorder.
CIA Director Andrew Lockhart (
Tracy Letts) confronts the Pakistani delegation, including Tasneem, and threatens to cut off US aid to Pakistan if Saul is not returned. After taking the replacement pills, Carrie becomes increasingly paranoid and erratic, suffering hallucinations and having violent outbursts. Carrie recovers in the care of Khan in "
Halfway to a Donut", and realizes she was drugged. A furious Tasneem tells Khan she orchestrated Carrie's breakdown to get her out of Islamabad. Khan was unaware, and helped Carrie in order to protect relations with the US. Immediately before a meeting between the Americans and the Pakistanis, Khan notices Tasneem talking to Dennis and passing him a note. Khan meets Carrie in secret and tells her that Dennis is working against her, but does not mention Tasneem's involvement. In "
There's Something Else Going On", Carrie confronts Dennis, who denies helping the ISI. Martha believes Carrie's suspicions, and has Dennis detained when he tries to flee the embassy. Carrie and Tasneem represent the CIA and ISI in a tense prisoner exchange for Saul. Tasneem conceals her alliance with the Taliban but is annoyed when Saul tries to martyr himself to prevent the exchange, and allows Carrie to go in alone to convince him. The convoy transporting Carrie and a freed Saul is attacked, which Dennis realizes could be a diversion for an attack on the embassy. He confesses to Martha that he told Tasneem about the embassy's hidden tunnel, just as Haqqani leads an assault team through it. In the middle of a firefight in "
13 Hours in Islamabad", Carrie calls Khan and asks him to send the Pakistani military to her aid. Tasneem insists that he delay making the call for ten minutes to teach the Americans a lesson. She believes they have been insinuating themselves in Pakistani business for too long, and that the US is more their enemy than their friend. Khan is horrified that Tasneem and the ISI are aiding Haqqani, a terrorist who has killed many of Khan's soldiers. At the embassy, Haqqani and his Taliban soldiers gun down multiple embassy personnel and take hostages, whom he begins to execute as the Americans resist his demands for their list of all CIA informants in Pakistan. In "
Krieg Nicht Lieb", CIA agent
Peter Quinn (
Rupert Friend) plots to lure Haqqani out of hiding by leaking a video of Haqqani killing his nephew, accompanied by a
call to action. A mob of protesters amasses in front of Haqqani's hideout. Tasneem stresses to Khan that Haqqani's safety is paramount, and says she will hold Khan personally responsible if anything happens to him. The ISI sends hostile Haqqani supporters to the scene to drive the demonstrators away. In "
Long Time Coming", Tasneem has benefited from the chaos she helped unleash and becomes a "leading" voice for Pakistan, publicly renouncing any alliance with the US.
Season eight Saul, now the
National Security Advisor to the US president, is in
Doha,
Qatar monitoring peace talks between the
Taliban and the government of
Afghanistan in "
Deception Indicated". The Afghan vice president, Abdul Qadir G'ulom (
Mohammad Bakri), jeopardizes the negotiations when he announces publicly that he will never release any Taliban prisoners of war, as has been proposed. Saul goes to Tasneem, who is now
Director-General of the ISI and is in Qatar observing the talks. Though not surprised that negotiations have fallen apart, she denies Saul's inference that the Pakistani delegation has leaked details of the talks. He is dubious, reminding her about the incident at the US embassy in Islamabad, when she held back her response team for two hours while 36 Americans were murdered. Later, Saul visits Tasneem, who tells him that her stepfather Bunran is not well, as his
muscular dystrophy is affecting his vision. Saul asks Tasneem to work with him rather than against him, as both of their countries share a desire for fair and durable peace in the region. Tasneem scoffs, noting that the US's withdrawal from the region after the
Soviet–Afghan War brought chaos and civil war on the Pakistani border. She believes that the US-built Afghan state is unstable, and criticizes US foreign policy, suggesting that the US cares more about removing itself from the region than peace. In "
Catch and Release", Tasneem becomes suspicious when Saul pulls five Taliban prisoners from the
Guantanamo Bay Naval Base and one of them disappears. Surveillance has indicated to Saul that Haqqani, now the leader of the Taliban, is receptive to ending the hostilities. Saul has secretly sent the fifth prisoner, Haqqani's cousin, to deliver a message to Haqqani in exchange for his freedom. Saul invites Haqqani to meet him in
Peshawar, Pakistan. Meanwhile, Tasneem visits Bunran and relates her suspicions that Saul is not in
Washington D.C. as she was told, but is in Pakistan to negotiate directly with Haqqani. Noting that it is not in Pakistan's best interest for the United States to control negotiations, Bunran tells Tasneem to do whatever it takes to prevent the meeting. Saul learns that the ISI are converging on his location in Pakistan, and is unable to prevent Haqqani's convoy from being struck by a Pakistani
RPG. In "
Chalk One Up", Tasneem and G'ulom are less than thrilled that the Americans have brokered a deal with the Taliban without them. Tasneem attempts to leave the announcement ceremony at the
Presidential Palace but is stopped by Saul, who makes it clear he knows she orchestrated the attack on Haqqani.
US President Ralph Warner (
Beau Bridges) comes to Afghanistan in person to announce the pending peace treaty with the Taliban, but the helicopter carrying him and
Afghan President Daoud (
Christopher Maleki) goes down in Taliban-controlled territory. When the presidents' arrival in
Kabul is delayed in "
Chalk Two Down", Tasneem tells G'ulom she has heard rumors of "helicopters down". They are soon shocked to learn that both presidents are confirmed dead. G'ulom warns Tasneem that the Afghan-Pakistani alliance will break down within hours, and he will no longer be able to guarantee her safety. ==Reception==
