Complete story — includes the ending
In an attempt to find out who helped Hamid kill himself, Carrie has a polygraph administered to everyone who was in contact with Hamid, including Brody. Raqim and Aileen discover that al-Qaeda is also attempting to eliminate them; Raqim is later killed, while Aileen manages to escape. The CIA begin tracking Aileen. After Walker's funeral, Brody attacks Mike over his affair with Jessica. He calls Carrie to a bar that night to socialize; the two get drunk and end up having sex, but not before Carrie reveals the purpose of the polygraph test to Brody. The next day, Brody passes every question on his polygraph, including whether he slipped Hamid the razor. Carrie requests that Brody be asked whether he has ever been unfaithful to his wife; Brody says no, and passes the polygraph. Carrie realizes that Brody is a skilled liar, though Saul believes he is no longer a suspect. Outside the CIA office, Brody has Carrie get in his car, and the two drive off.
