his 20 year secret spy life and lair. In the message, he states that he "did it all for her," i.e. Mary. In the lair, is a box labeled "MARY ELIZABETH BARTOWSKI: MISSING." In Mary's file it is revealed that her parents are Jesse and Mary Gunter, and she was born in December. As Chuck walks through the lair, he finds a table on which sits the "boy" half of the broken necklace. The scene then shifts to a woman at a desk who receives a phone call, telling her she needs to move immediately. When the camera angle changes, it is revealed that the woman is wearing the "girl" half of Mary's necklace as a bracelet. Linda Hamilton first appeared in the role in "Chuck Versus the Anniversary". Mary monitored Chuck's discovery of a safe house in LA, where a menu for a Chinese takeout restaurant provided him and Morgan with clues implicating Volkoff Industries in her disappearance.

After the team's escape from Volkoff's headquarters, Mary herself escaped custody after killing several of her captors. Mary resurfaces in "Chuck Versus the Aisle of Terror", after having contacted Chuck in the previous episode.

However after a series of double and triple-crosses in which she ultimately aids the team in capturing Wheelwright, Mary's ultimate allegiances remain unknown, and she is apprehended by Sarah and Casey without Chuck's involvement or prior knowledge. The ambiguity persists into "Chuck Versus the First Fight". After her arrest Mary convinces Chuck to seek out her MI6 handler, Tuttle (Timothy Dalton), who can provide intelligence clearing her name. When Chuck is captured, she agrees to help Sarah and Casey locate him after a deal brokered by Morgan to see Ellie. During the meeting she provides carefully worded hints that help Ellie locate a hidden message Stephen left for her in the event of his death. After Chuck, Sarah and Tuttle recovered the MI6 data clearing her, she accompanied Chuck and Sarah back
