Time Will Tell
Sydney travels to Oxford to steal an ancient clock connected to the Rambaldi mystery. She successfully completes the mission, though Anna Espinosa is hot on her trail.
Jack confronts Sloane about the death of Eloise Kurtz, and admits that he hired the woman, a young SD-6 agent, to impersonate Kate Jones. Sloane, however, did not trust Kurtz and had her silenced.
Sydney discovers that SD-6 has hired an agent to trail her. Sloane insists that it is a routine procedure, but Jack tells Sydney that SD-6 suspects they have a mole. He urges his daughter to seek help from Vaughn on how to fool a functional imaging test -- a sophisticated lie detector.
Sydney's next assignment takes her to Positano, Italy to have the clock repaired. The clock was designed by Rambaldi, but built by a master craftsman named Giovanni Donato in 1503. One of Donato's descendants still pursues the family craft, and can repair the artifact.
Meanwhile, Will's editor rejects his story about the mysterious deaths of Danny Hecht and Eloise Kurtz. The story contains questionable facts, and editor Litvack suggests that Will is lying. She demands that he cease his investigation, but Will has other ideas. He is tipped-off to the location of Kurtz's car, and continues playing detective. Inside the car, Will finds a piece of jewelry, which turns out to be a piece of sophisticated surveillance equipment.
In Italy, Donato explains that the symbol on the clock, <0>, is the mark of the Magnific Order of Rambaldi. When Sydney asks about a date engraved on the clock, Donato says that Rambaldi never told him what it meant. The old man returns the repaired clock, and a K-Directorate sniper, aiming for Sydney, kills Donato instead.
Back at home, Sydney reads a book that her father had given to her mother. She uncovers a Russian code embedded on each page.
At SD-6, Marshall discovers that the glass disc from the church in Malaga fits into the clock. When the artifacts are together, a star chart is revealed. Marshall deduces that the chart was made from a specific location on Mount Aconcagua, near the border of Chile and Argentina. Before Sydney and Dixon can travel to the mountain, Agent Dreyer gives Sydney a functional imaging test. He doesn't reveal the results to her, but he later confides to Sloane that "we've found our mole."
At Mount Aconcagua, Sydney and Dixon discover a tunnel marked with the <0> symbol. Sydney goes in alone, leaving Dixon on the surface. Once underground, she discovers a book with designs from Rambaldi.
Before Sydney can retrieve the book, Anna appears and grabs the book. As Sydney pursues her arch-rival, she falls from the rickety ladder and plunges into the darkness.
Sloane: Tell me something. How did Tippin get a lead on the Kate Jones alias in the first place?
Jack: I don't know yet, but I'm looking into it.
Sloane: Well, your efforts notwithstanding, that reporter may be a casualty of his own curiosity.
Jack: I'd consider that a last resort. I know you want what's best for Sydney, and if at all possible, we should spare her the pain of losing someone else.
Jack: Lie detector test.
Sydney: I studied the C.I.A. instruction book on how to take a successful LDT.
Jack: This isn't like that. This test monitors variations in blood flow in the brain. It's very difficult to deceive. Tell your handler Vaughn he needs to prepare you for this. If he can't, he'll get someone who can.
Boss: And on the eve of your first front-page story, you suddenly get cold feet.
Will: What are you saying? What are you saying? I made this whole thing up? Look, I swear to God, the only reason I didn't want this story to run is 'cause I don't want to hurt Sydney Bristow. That's it.
Boss: You're a talented writer, Will. But I promise you, if anything like this happens again, the only thing you'll be inventing are facts on your résumé.
Sydney: Got it. How do I look?
Dixon: For the record, that's a question you never have to ask.
