The Entire Homeland Timeline Explained

Carrie convinces Yevgeny to help her locate Max, in the hopes of rescuing him and tracking down the flight recorder in order to determine whether or not the helicopter was actually shot down. Saul has her sent back to Germany after learning more of her relationship with Yevgeny, but she escapes and leaves the airport with him. They track down the flight recorder and try to rescue Max. Haqqani is tried and sentenced to death, later killed by firing squad and Jalal executes Max as revenge before assuming command of the now resurgent Taliban and falsely taking credit for shooting down the helicopters. Carrie tells Saul she knows where the flight recorder is but she's placed under arrest, only to escape with Yevgeny once more. They listen to the flight recorder, at which point Yevgeny drugs Carrie and takes the black box.

As tensions tighten with Pakistan, Carrie tells Saul that Warner's chopper went down accidentally and he tries to secure the flight recorder from his Russian contacts, to no avail. Yevgeny agrees to release it in exchange for either the identity of Saul's mole in the Kremlin or Saul's death. Saul refuses to identify his contact, so Carrie plays dirty, eventually identifying Russian interpreter Anna Pomerantseva as the mole, betraying Saul in the process. Anna kills herself rather than face capture and Russia releases the flight recorder data themselves, averting war between the U.S. and Pakistan. 

Two years later, Carrie lives in Russia with Yevgeny, having denounced the U.S. in a tell-all book. She sends Saul an advanced copy with a note hidden in the binding, the same way Anna communicated with him, meaning Carrie has replaced Anna as Saul's asset within the Kremlin.
