NCIS, Season 2

[Kate leaves the isolation chamber and bursts into tears.]

Ducky:
[hugging her] You were brave to stay with him, Kate.

Kate:
[sobbing quietly] He's dying, Ducky.

Gibbs:
[walks past them] Oh, the hell he is.

[Gibbs enters the isolation chamber without a mask.]

Dr. Pitt:
Whoa, whoa, whoa. Who the hell are you?

Gibbs:
His boss. The bug has a suicide gene. It's dead. It's been dead for over an hour. He's no longer infectious. (whispers to a very ill Tony) Tony, listen to me. Are you listening?

Tony:
(weakly) I'm listening. I'm listening, Boss.

Gibbs:
(whispers) You will not die, you got that? (beat) I said, you will not die.
