The CIA learns that Lisenker hid a disk with important information about the Covenant in a chalet in Chamonix; Syd and Weiss travel to Greece to find the woman who designed the chalet's deadly security system. She provides details about the system, but she adds confidently that there is no way to bypass it. Jack visits Sloane, who says that he forgives Jack for the Katya incident. Sloane confides that he feels alone: Emily's absence has left a void in his life. Meanwhile, Syd talks to CIA psychiatrist Dr. Barnett, telling her that she can't move past her feelings for Vaughn. Sark approaches Lauren, suggesting that they work together to obtain more power within the Covenant. She agrees and they set to work murdering six cell leaders. Sloane shoots up with a mysterious green fluid, then calls Jack asking about the psychiatrist that Jack had mentioned. Dr. Barnett visits Sloane, but he tries to elicit information from her about Jack and Sydney. Dr. Barnett persists in trying to help him, and he finally confides that he has a secret that wears on him. Jack accompanies Syd and Vaughn on the mission to Chamonix; as Marshall guides them via remote from his lab, Carrie goes into labor. Still, Marshall is able to help and - with a lot of luck - they retrieve the disk. Sark travels to St. Petersburg to meet with the head of Covenant operations: it's McKenas Cole, the former SD-6 agent. To Sark's surprise, Lauren is there: she informed Cole of Sark's plan. However, knowing that the CIA has acquired the disk, Cole believes that Sark's treachery has benefited them. Cole rewards Sark and Lauren by putting them in charge of the North American cell, but he hands Lauren a photograph and suggests she put an end to her husband's extracurricular activities. Back at the CIA, Lauren approaches Sydney and tells her to stay away from Vaughn.
Jack: About last week: it was a matter of circumstance, Arvin. Whether I would have gone through with it--
Sloane: Oh, you would've. I would've.
Sloane: And now you feel guilty. Well don't bother, Jack. Sydney's life was at stake. How can I blame a man for doing whatever he can to save his daughter's life?
Sydney: Now that I know what happened to me over the last two years, in theory I should finally be able to move on with my life.
Barnett: "In theory."
Sydney: The thing is, when I look ahead all I see is Vaughn.
Barnett: How would you feel if Vaughn left his wife for you?
Sydney: I don't know. I don't think he would ever leave his wife because of me. I mean, I think it would be because he and Lauren don't belong together.
Barnett: Does he belong with you?
Sydney: Have you ever felt that someone's your soul mate?
Vaughn: Do you think you can be in love with two people at the same time?
Weiss: No, I don't. However I did have the same intense feelings for both Sport and Posh Spice.
Vaughn: Yeah, who didn't?
Sark: Once we eliminate all six cell leaders, we'll travel to St. Petersburg to meet with the head of Covenant Operations.
Lauren: Why? To make it easier for him to kill us?
Jack: You realize it is your prerogative to ask Dixon to send someone else.
Sydney: If Dixon sends me on an operation, I'm going.
Jack: What I mean is, someone instead of Vaughn.
Toni: And how do two South African rock wranglers hear about Chamonix?
Sydney: The owner was a client.
Toni: Yeah, I outdid myself on that one. If you're interested in a job like that, those stones won't even cover the down payment. They barely cover this conversation.
Sloane: I presume that you treated Sydney and Jack Bristow before.
Barnett: I can't discuss other patients with you.
Sloane: Then they were your patients?
Sydney: Every day I wish I could go back in time, but I can't. And as much as I... as much as I still have feelings for you, I won't be the other woman - not ever.
Vaughn: I know.
Sloane (to Barnett): I manipulate people. I'm good at that, and I know it. I lie. I keep secrets. I divulge only what I must in order to elicit the reaction I need. That skill, in part, is why I'm still alive. One of those secrets affects the only two people I care about in the world, Sydney and Jack Bristow. There are many secrets I enjoy keeping. There is power in secrets that you keep. But this one . . . no. This one wears on me. It has for many years. It's central to my very existence. It's who I am.
Cole: Your hair - that's cool!
Sark: You're the man behind the Covenant.
Cole: I'm the man in front of The Man. When'd you cut your hair?
* Apparently, Sark's first name is "Julian."
* Does the episode's title refer to (after) the deaths of the six cell leaders?
* Perhaps the ending would have been a surprise if pictures all over the 'Net didn't reveal that Lauren was with Cole.
* I just wasn't feeling the danger, on Syd and Vaughn's dangerous mission.
* The green goo was probably some Rambaldi potion that makes Sloane appear to be telling the truth. (Recall earlier this season when Sydney insisted Sloane was outsmarting their high-tech lie detector.)
* When Marshall observed that the baby was kicking at an odd time, I wondered if Carrie was a bad guy, trying to distract them.
* I really thought Sloane was going to suddenly torture Barnett for info on Syd and Jack.
* What was that picture that Cole had: did someone photograph Syd and Vaughn kissing in a North Korean prison?!
