S2 episode 9 Aired on August 2, 2011

A CIA case officer, codename Moonlight, was killed in the line of duty. The agent turns out to be Annie's language professor from Georgetown University, Dr. Mark Ramsay. Annie is stunned to discover that he was part of Langley and is now dead. Ramsay was tracking a local Pakistani state-sponsored spy ring called Lashkar-e-Taiba.

In light of Annie's relationship to Dr. Ramsay, Joan and Arthur order her to go to the doctor's grieving widow, Safia, to tell her the truth about her husband's clandestine occupation. But Annie is also tasked with locating Dr. Ramsay's classified documents that have been stored on microdots, an archaic CIA device that shrinks a full document down to the size of a period.

As Annie and Safia walk in the backyard of the Ramsay's home, Annie presents her with a CIA commendation report. However, the widow doesn't believe Annie and will hear nothing of it. Annie follows the agitated Safia back to her home and it's only then that Safia begins to understand the truth. The two find her home torn apart and hear the intruder coming down the stairs...
