Plot
Saul (Mandy Patinkin) talks with Dar Adal (F. Murray Abraham) at a local diner. Adal confirms that Peter Quinn (Rupert Friend) is one of his men on loan to Estes, but for what purpose, he claims not to know. Later, at Langley, Saul confronts Estes (David Harewood) regarding why Quinn is involved in the operation. Estes becomes furious when Saul implies that Quinn was brought in to kill Brody to cover up Estes' complicity in the drone strike that killed Abu Nazir's (Navid Negahban) son Issa. Quinn approaches them, reporting that Carrie (Claire Danes) was in a car accident and is now missing. Saul heads to the accident scene. While he is gone, Estes tells Quinn "he knows."
At the safehouse, Jessica (Morena Baccarin) and Mike (Diego Klattenhoff) reminisce about sleeping together the previous night. They begin kissing, but stop when they hear Brody (Damian Lewis) at the door. Brody receives a call from Nazir, who has taken Carrie hostage in an abandoned mill. He rebukes Brody for betraying him and threatens to kill Carrie unless Brody carries out a task for him. He orders Brody to enter Vice President Walden's (Jamey Sheridan) home office at the Naval Observatory and retrieve a serial number that corresponds to Walden's pacemaker. He explains that he will be able to use the serial number to manipulate the pacemaker wirelessly.
While Carrie and Nazir get into a heated debate of ethics, Brody goes to the Naval Observatory to find that Walden is in a meeting with the Israeli ambassador to the United States. He sneaks into Walden's office and sends the serial number by text message to Abu Nazir, only after confirming that Carrie has been set free. Nazir sends the serial number to an associate who is sitting at a computer. Walden, finished with his meeting, enters his office and finds Brody. Brody tells Walden that he is withdrawing as a candidate for vice president in order to take care of his family; Walden bristles at the idea. Nazir's associate gains access to Walden's pacemaker and accelerates his heartbeat, inducing a heart attack. Brody sees Walden struggling and reveals his true motivations for withdrawing: his desire to be "clean" again and his disagreement with everything Walden stands for.
