Sloane confides to Jack that Senator Reed recruited him two years ago to work with a secretive government organization called The Trust; if Jack can prove that this group exists, perhaps Sloane's execution will be stayed. The CIA learns of a computer worm that is targeting medical facilities; they believe this attack is somehow connected to The Covenant's search for The Passenger. Sydney and Vaughn go to find the hacker who created the worm. He's shot before he can tell them anything, but he manages to give them a small drive containing the worm's source code. Syd sees Lauren, but a chase seems to reveal that she was mistaken. However, Syd is still suspicious, particularly when Lauren shows up at the safehouse shortly before the worm's source code files are damaged. Jack pays Vaughn a visit, saying that he regrets ignoring the signs of Irina's deception; Jack recalls that when he would ask about her day, she would try to distract him with a kiss. Vaughn angrily says that Lauren is not Irina. Marshall is able to reconstruct the data and determine that the worm was searching for the woman who matched a certain genetic code. The woman's doctor is located, and Sydney and Vaughn travel to speak with him. However, Lauren arrives first, and tortures him for The Passenger's location. Later, Syd wonders if The Passenger is her mother. Jack's contact provides proof that The Trust does exist, but before Jack can share this information, he learns of Sloane's affair with Irina. Jack coldly tells Sloane that he found no trace of the group's existence. Elsewhere, Vaughn asks Lauren what she did while he was gone; she responds by crossing the room to kiss him. When she leaves, he searches through her things. Behind a false panel in her suitcase, he finds a gun, a passport, and a wig identical to the ones from the bar where the hacker was shot.
Weiss: You know, Syd, nobody would blame you for hating him for going back to her.
Sydney: He's not the one I hate. How horrible does that sound?
Weiss: Well I'm mad at her, and I don't even think he's that cute.
Sydney: My dad thinks Lauren's leaking information to the Covenant.
Weiss: I don't understand - didn't Senator Reed confess to being the leak before he died?
Sydney: Yes, and his confessions answered all the questions my father had raised. But I can't help it, I still have doubts.
Weiss: All right, let me ask you a question: do you think she's the mole, or do you just want her to be the mole?
Sydney: Are we sure he'll have his computer with him?
Marshall: Does a cowboy leave his gun at home when he goes to the saloon? Trust me, he'll have it.
Bomani: This girl, her work for us of late has been uneven.
Sark: The Il Dire machine is in our possession because she managed to steal it from the CIA. She is a considerable asset.
Bomani (skeptical): An asset for you in ways that do not interest me.
Vaughn: Lauren, no one's judging you.
Lauren: I've seen the way they look at me - like I'm a traitor too. To tell you the truth, I don't blame them.
Vaughn: People are just angry.
Lauren: And I'm not? He was my father! You have no idea what it's like to think you know someone, to love them, and then figure out it was nothing but lies.
Cypher: Nice trick. Looks like I'll have to readjust my firewall settings.
Sydney: I could still get through.
Vaughn: What, are you suggesting Lauren framed her own father?
Sydney: I know it's hard for you to consider.
Vaughn: Hard for me?! My wife just found out her father was betraying her, not to mention our country.
Sydney: But if I saw her--
Vaughn: You didn't.
Jack: What about Vaughn?
Sydney: I've tried talking to him about it. He won't even entertain the possibility. It's like he can't hear it.
Jack: Perhaps he can't hear it from you.
Jack: I don't regret having married her. I have Sydney because of our time together. What I do regret is that once I saw signs of her duplicity, once I sensed her betrayal, I chose to ignore it. All I'm asking is that you be responsive to the signs if and when they present themselves.
Vaughn: You never respected me. Never thought I was worthy of your daughter. So I'm not surprised you're so quick to think Lauren is betraying me. But whether or not you or Sydney believe me, I know the life I'm living, and I know the woman I am married to. Lauren is not Irina, and I am definitely not you.
Lauren (on the phone): What else did Bomani tell you? Did he instruct you in the quietest way to murder me?
Sark: Absolutely not.
Lauren: You pathetic little errand boy. Tell Bomani he'll get proof of my worth the next time he sees me, when I deliver the Passenger.
Dixon: You recall that I requested Dr. Barnett's notes from her sessions with Sloane?
Jack: Yes. Did they reveal anything?
Dixon: Yes. There is something in the notes that concerns you. In one of his sessions with Barnett, Sloane admitted having an affair with Irina while you were married.
* Why were Sark and Lauren so afraid of Bomani, if he is so easily killed with no consequences?
* So Sloane did talk to Senator Reed; I thought that was just part of the frame.
* What possible reason could Lauren have for not discarding that wig as soon as she changed out of her disguise?
* Since Barnett documented Sloane's confession in the notes from her restaurant chat (aka "session"), she betrayed his trust after all. Maybe she is evil.
