Alias: S.O.S./Maternal Instinct

Warning: many spoilers follow!

(S05E10/S05E11) So there's a mole inside the CIA that's helping Prophet 5 with their mysterious plans for Sydney and her baby. Who is it? And how will the APO gang find the mole in time to save Sydney?

If you watched another show earlier this week, the mole will come as no surprise to you...

It's Barry Goodwin, the DNC guy from The West Wing! Jeez, no wonder Josh doesn't want him to head Santos' transition team!

Jack, with help from the team and Weiss (and especially Marshall, who I have decided is the most important cast member on this show - they'd be lost without him) find out who the mole (Davenport) is and Jack shoots and beats him in front of other CIA heads to find out where Syd is being held. Syd is still on the cargo ship, tied to a table with monitors attached to her. They have plans for the baby, but she doesn't know what those plans are. The APO team heads to save Syd.

How come Kelly Payton is OK, by the way? Didn't Syd stab her in the neck with a needle in the last episode?

The doctor puts Syd under. And then we find out that Subway has a new sandwich. Oh, it's a commercial. Sorry.

The APO team reaches Syd, who is alone in the infirmary, with bloody bandages around her. The team takes her off the ship, as Prophet 5 threatens Sloane over the phone: continue to help us or your daughter will never get better.

Meanwhile, Marshall finds out that Thomas accessed secret files while in the CIA. The witness protection program files. The man who killed his wife. Thomas meets the man in a parking garage. The man calls him "Peter" and says he was sorry, he was under orders. Thomas says that's not why he's here. He has to get a message to the Cardinal. (?!?)

Jack goes into Syd's room and tells her that there was a problem with her baby. And the doctors on that ship weren't trying to hurt the baby, they actually saved the baby's life.

The CIA mole is being transported, and you know that's not going to end well. The ambulance is smashed by a mack truck. The guards are killed. It's Irina. She goes over and kills Davenport.

Marcus "I've got a new cool hairstyle" Dixon takes Syd to meet Jack, who has been released by Devlin (for torturing Davenport and investigating Prophet 5 on their own) if they promise to stop investigating Prophet 5 (yeah, right). Jack wants Syd to contact Renee', and then he wants her to go home and pack. He wants to get her to a safe location.

Syd wonders what Dean meant when he said that P5 (I'll abbreviate from now on) had plans for the baby. Marcus tells her that she should go into hiding like Jack says, because she "waddles." Syd goes home and Irina is there waiting for her. (Gee, great security for people who want to protect Syd from being kidnapped again!)

Syd is happy to see her, but Syd wants her to get out because it's not safe. But Irina tells her that she knows about P5, and that she's there to help. She tells Syd that P5 is looking for The Horizon. Syd says she's never heard of it, but Irina says that P5 thinks she does. Syd tells Irina about Vaughn.

Jack asks Marshall for info, but doesn't want it tracked back to the APO office (so Devlin doesn't find out). Jack tells Marshall to forward the info about someone named "Bertram" to Dixon.

Jack goes to Syd's to talk to Irina.

Dixon goes to meet Bertram in Paris. Renee' is there. Dixon confronts Bertram about a mission he did 7 years ago for the Alliance. They talk a lot of French to each other. To refresh his memory, Dixon and Renee' tie him to the hood of a car and take him on a hell ride. He tells them about a P.O. Box in a bank. Jack and Irina are going to go get The Horizon. Syd insists on going too. It's only a 3 hour flight and The Horizon is why Vaughn was killed.

The Bristows go to the bank and pose as a mom, dad, and daughter. Well, they don't really have to "pose" because they really are. But they do it with accents!

Meanwhile, Rachel confronts Thomas about his activities. He tells her he went to him. But he lies and says that he didn't do anything because the man had a wife and son. He just walked away and decided not to kill him because that wouldn't bring his wife back.

Back at the bank, I'm not even sure what's going on. They get money or something and ask the bank if they can have a safety deposit box. The bank guy takes Jack and Irina to the box, while Syd stays in the office and calls Thomas for help. He patches her over to Rachel because Devlin is standing there.

Rachel helps Syd with the encryption, and as Syd is leaving the room, she sees the monitor: Kelly is killing bank officials. In the safety deposit room, Jack and Irina are about to open the box when Irina pulls out a knife and attempts to stab Jack! Jack controls her. Syd rushes in and realizes that Irina was the one behind the glass holding her on the ship. Irina tells them that Kelly and the guys are coming to kill them and that she's not one of Kelly's team.

Back at APO, Devlin and the team are looking through the computers, trying to find out who leaked info about P5. Sloane convinces Rachel to erase the files.

Irina insists she isn't part of Kelly's plan. She says that Jack and Syd should give her The Horizon and she'll tell them that they escaped. Syd is having labor pains. The three of them go up to the roof to meet Irina's helicopter. Kelly and her team are on their tail. The Bristows wait for the helicopter to land...but Kelly destroys it from a lower floor with a missle.

Sloane instructs Rachel to delete certain files, but it's on the same page they are now looking at. But Sloane tricks Devlin into going to a different page so Rachel can delete the file that will incriminate him (though Rachel doesn't know that's what it is).

Irina tells Syd she tried to warn Vaughn about his investigation, but he wouldn't listen to her. Jack goes down to take care of Kelly and her men. Jack kills two of her men. Syd continues to experience pains. Irina tells her that she never wanted to have a child, but the KGB demanded it. But when the doctors put Syd in her arms, she changed her mind. She couldn't be an agent and a mother. So she chose at failing to be a mother. She tells Syd "in time you'll learn you can't do both."

Syd gives Irina the gun and she kills a guard.

Downstairs, Jack shoots a fire extinguisher and kills Kelly.

Upstairs, Syd is going into labor. But the baby is coming out backwards. Irina tells her to breathe in and out and relax. Jack tells her to imagine being on the beach. With Vaughn. Syd pushes, and gives birth to a baby girl (one of the more unrealistic births I've seen on TV in a while, but whatever). While everyone is happy, Irina takes The Horizon and vanishes.

Irina calls Marshall and tells him where to rescue Syd and Jack. And to bring diapers.

In Bhutan, a man on a horse brings good news to a man in a cottage. He has a daughter...the man is VAUGHN!
