3. The Covenant

Complete story — includes the ending

Sekou's plea deal is revoked because of Carrie's meeting with Saad. Carrie reaches out to a former NSA contact to obtain a recording proving that FBI agent Ray Conlin attempted to entrap Sekou on false charges, and uses it to blackmail Conlin into releasing Sekou. Saul arrives in Abu Dhabi to interrogate Farhad Nafisi, an Iranian banker, about a large transfer of funds made from a covert account. Nafisi denies any involvement with North Korea; Saul is unable to prove he is lying and is forced to release him. Dar nonetheless reports to Keane that the U.S. has "conclusive" evidence of Iran's parallel nuclear program; he later eavesdrops on a meeting between Keane and Carrie, who casts doubt on Dar's report. Saul visits his sister in the West Bank and has an unknown contact pick him up at night. Quinn reclaims his gun from the drug dealer who robbed him and lurks outside Carrie's apartment armed with it, believing that someone may be spying on them.
