Weeks later, Carrie regains custody of her daughter and works as an intelligence advisor to the White House, but is abruptly fired amidst President Keane's mass roundup of federal employees in retaliation to the assassination attempt.
Months later, an injured Brody resurfaces in Caracas, where a group of mercenaries with CIA connections tend to his wounds and keep him addicted to heroin in a slum that grew out of an abandoned skyscraper.
Saul is doggedly committed to his job, often at the expense of his personal life: he has a wife, Mira, who resents his absence at home (which ultimately results in their divorce), and a sister, Dorit, who lives in the West Bank and has not seen him in years.
Saul intends to send Brody to Iran under the guise of seeking political asylum so that he can kill Danesh Akbari, leader of the Revolutionary Guard, who will then be replaced by Javadi - ushering in a regime change in the nation.
Some time after the Taliban's assault on the U.S. embassy, Saul learns from Dar Adal that Haqqani agreed not to harbor terrorists in Afghanistan in exchange for being removed from the CIA's kill list.
Two years later, Saul is called to Berlin to attend to a scandal involving leaked documents attesting to widespread privacy violations by the American and German governments as part of a counterterrorism probe.
Saul investigates Iran's possible violations of their nuclear treaty (based on a false lead planted by Dar), visiting his sister Dorit in the West Bank as cover to secretly meet with Majid Javadi.
When tensions between the U.S. and Pakistan nearly culminate in a war, Saul and Carrie work to obtain the helicopter's flight recorder, which proves that the crash occurred due to mechanical failure, but is in the hands of the Russians.
Saul discovers that Estes and then-CIA-director Walden ordered a drone strike launched in Abu Nazir's homeland, resulting in the destruction of a nearby school and that his efforts to undermine Carrie were actually an attempt to cover up the incident.
Quinn soon becomes convinced that a man living across the street from Carrie is spying on her, which leads to him uncovering a vast conspiracy by Dar Adal's group to discredit (and later assassinate) President-elect Elizabeth Keane.
After Saul is named acting CIA director following the 12/12 bombing of the Langley headquarters, he and Dar work together to dismantle the network of Majid Javadi, the Iranian deputy intelligence chief who financed the attack.
Dar soon learns that a faction within his cabal (led by General Jamie McClendon) has escalated the scope of the operation without his approval, and are now plotting to assassinate Keane and frame Quinn as the perpetrator.
Otto provides Carrie his home as a temporary safe haven while she investigates the origins of an attempt on her life, and gives her a copy of classified CIA intel passed to him by Saul (which allows her to discover Allison Carr's double agent status).
When Quinn uncovers a homegrown conspiracy against the President-elect, Max goes undercover in Brett O'Keefe's shadowy private company, which he learns is a troll farm whose services are being solicited by Dar Adal.
Carrie and Dante begin investigating David Wellington, the president's chief of staff, for possible links to the assassination of Jamie McClendon, the corrupt U.S. Army General who spearheaded the plot to eliminate Keane.
Years later, Saul covertly meets with Javadi in the West Bank amid rumors in Washington that Iran is running a parallel nuclear program, thereby violating the terms of their agreement with the IAEA.
He is one of the survivors of a CIA drone strike intended for his uncle, Taliban leader Haissam Haqqani, which instead struck a wedding that killed several civilians including Aayan's mother and sister.
Carrie initially avoids taking care of her daughter, leaving the infant Frannie to stay with Maggie while away in Kabul, and nearly drowning the child in a bathtub while spending a day watching over her.
Played by Robert Knepper, General Jamie McClendon is a corrupt military officer who leads a faction of Dar Adal's black ops group in a conspiracy to assassinate President-elect Keane, planning to frame Quinn as the culprit.
Played by J. Mallory McCree, Sekou Bah is a Muslim teenager living in New York City who alerts the FBI's attention after posting a series of online videos denouncing U.S. foreign policy in the Middle East and sympathizing with Al-Qaeda.
Saul interrogates him to learn about Iran's possible underground nuclear program, unaware that it was a ruse orchestrated by Mossad (alongside Dar Adal) to manipulate President-elect Keane's military policy.
Carrie soon learns that her source, FBI agent Dante Allen, is a Russian asset (alongside Simone), working to sabotage the Keane administration by implicating Wellington in the McClendon assassination.
Simone makes a series of money transactions that enable the assassination of General Jamie McClendon in federal prison, and later attempts to testify in Congress implicating White House Chief of Staff David Wellington, her occasional lover, as the orchestrator.
When Carrie and Saul learn of Simone's role in the Russians' subterfuge, they attempt to recover her from witness protection, but she is extracted by GRU operatives led by Yevgeny Gromov, her actual lover.
Played by Peter Vack, Clint Prower is a young but capable analyst from DARPA that Saul recruits to his task force to investigate Russian interference in the Keane administration.
