Complete story — includes the ending
The CIA inform Tom Walker's family (but not Brody) that Walker is still alive. Walker is shown to be homeless in Washington, D.C.; he receives a key and note from Mansour al-Zahrani, a Saudi diplomat. Walker is discovered to be routinely calling his family to hear their voices; the FBI traces the next call between Walker and his wife Helen, but Helen warns him to run. The FBI chases Walker through a mosque where they accidentally kill two attendees; Walker uses his key and note to retrieve a sniper rifle from a storage unit. Carrie visits Brody and reveals that Walker is alive and working for al-Qaeda; that night, Brody attacks al-Zahrani at his home and tells him that he is done talking to Abu Nazir, revealing that he has remained in contact with Nazir despite proclaiming his innocence.
