Mandy sneaks through LAX, with this keycard she should be able to release the virus into the ventilation system. Then the alarm goes off, this place is being locked down, she needs to move quickly. At CTU Hammond comes to see Audrey one more time. He again threatens her, and again she refuses to cooperate. Hammond is getting very angry. He tells the torture man to leave, he wants to deal with Audrey personally. Meanwhile Vicki sees David Hoffman in private. She waits until he's done on the phone. David just warned LAX about the attack.
.
Vicki: I know you're helping Nadia Yassir and Jack Bauer. And I want to help.
David: Why is that?
Vicki: Either Hammond or Jack is working with Max, I believe it's Hammond. He tried to blackmail me, I doubt he would've done that if he were innocent.
David: Blackmail you over what?
Vicki: I'm gay, in love with a woman named Meghan.
David: That's it?
Vicki: Yes.

David was unsure he could trust Vicki. But he needed someoe at Division to get the intel to the right people, so he told her everything. At LAX Mandy reaches the ventilation system. She sets a five minute timer and flees. As Mandy flees officer Hayes, the head of security, stops Mandy at gunpoint and orders her to surrender. Mandy knows she's defeated, tells Hayes exactly where the virus is. Hayes relays it to Jack and he rushes to the system. But ven Jack Bauer is too late.
