Vaughn tells Sydney she's clear. Sydney opens the door to the weapons silo and descends. She asks him for directions, and Vaughn directs her to "the package." It's very dark and very boring. Hassan feeds directions to Vaughn, and from there it goes to Sydney. My God. It is so the opposite of fascinating to describe. Essentially, Hassan feeds her the code, and she gains access to the inner sanctum. It's a big warehouse filled with boxes. Vaughn tells Sydney that Hassan says (sigh) to look for black shipping cases. Sydney heads toward the center of the room and starts opening packages. After a couple, she tells Vaughn, "I found the refractor," only to have the doorway start closing.

Sydney gasps, "Vaughn, I think this is a set-up!" as the room turns black. The light comes back on as she tells him that the entire room is going into lockdown. Vaughn snaps at Hassan, "What the hell did you just do?" Hassan tells him he gave her the wrong code, that Sydney actually has set off an anti-intruder device. The whole room will fill with gasoline, and one minute later a flame will ignite. Meanwhile, the scene cuts to Secoulis, who's been alerted to an intruder.

Sydney is frantic. Cut back to the CIA control room, where Hassan calmly tells Vaughn that he won't tell him the proper code until he guarantees safety for his wife and son. Michael Vartan is trying to look intense and like a man pushed to his limit in this scene, but unfortunately all that's coming across is "cross-eyed." He cocks his gun and tells Hassan that if he doesn't get the code, he's going to pull the trigger. Hassan calls his bluff. Vaughn backs down and tells Weiss to start typing as he runs up the stairs.

Meanwhile, Sydney is choking as the warehouse fills with gas. Vaughn: run run run. Weiss: type type type. Hassan tells Weiss he misspelled his name. Weiss tells him to shut up. Vaughn bursts into Devlin's office and tells him that if he doesn't get his signature on the agreement for Hassan, Sydney Bristow will die.

Back to the warehouse. Sydney is still choking. Devlin and Vaughn enter the CIA room. Devlin starts to sign the agreement, only his pen runs out of ink. He gets a new one. How needless was that?

Hassan gives Vaughn the code. Vaughn transmits it to Sydney. She punches it in, and the gas shower stops. Back in the CIA room, everyone gasps with relief. Back in the warehouse, Secoulis enters, only to pull a gun. Sydney warns him not to shoot, since the room is filled with gasoline. Secoulis obeys, but then pulls a knife. They fight. Sydney feints and ducks, and at one point his knife goes into the control panel by the door. She side-kicks him and takes off. His eyes widen in horror as the control panel sparks. The silo ignites. Sydney barely gets away.
