JACK: He wants a meeting to discuss the purchase of the Rambaldi manuscript. Only you. SLOANE: It's good to see you again, Irina. SLOANE: Where? SYDNEY: Answer the question. She looks out the window.) VAUGHN: Because I believed your father was right about her having a secret agenda. VAUGHN: Well, this one we should've been.

A: the Agency; Q: Who was slow? A: a lie; Q: What was Vaughn trying to catch Irina in? A: additional information; Q: What did Vaughn want to discover about Irina? A: Dixon; Q: Who does Sydney welcome to the CIA? Summary: Sydney begins to question where Vaughn's allegiances lie when she learns through CIA Agent Yaeger that he is under investigation. Meanwhile Irina and another crucial Rambaldi manuscript-this one about the secret of eternal life-are used as bait to try to catch Sloane. It turns out Vaughn had only been investigating Irina through his own means because the Agency was slow and he wanted to see if he could catch her in a lie or discover additional information. Sydney also welcomes Dixon to the CIA.
