It's been nearly a year since Carrie Mathison drew a star in the memory of Brody (Damian Lewis), privatley preserving his memory. With his baby on the way, and having just become the youngest station chief in CIA history, Mathison has a long year laid out in front of her.
Four months after the death of Brody, Lockhart (now CIA Director) offers Carrie (now eight months pregnant) the job of station chief of CIA's Turkey operations (after a maternity leave). Carrie accepts the position but her request to place a star on the memorial wall to commemorate Brody is refused. In the final scene, Carrie is seen discreetly drawing a star on the memorial wall herself.
