Stargate Atlantis, Season 3

[Sheppard and McKay burst into the brig, where O'Neill and Woolsey are being held]

Gen. O'Neill:
Hey! Thanks for the rescue!

Dr. McKay:
Oh, hey...no problem.

Gen. O'Neill:
No! You should be saying, "Thanks for the rescue!"

Dr. McKay:
Oh, ah, right...thanks. Should have you out of there in no time. This won't take long at all.

[McKay fiddles with the door controls, an error tone sounds]

Dr. McKay:
Oh, my...they, they, they've changed the codes.

Woolsey:
...But you can crack it, right? You need to get us out of here!

Dr. McKay:

Woolsey:
What? To destroy Atlantis with nuclear weapons? I thought we were past that! Why would we be going back to that?

Dr. McKay:
Yeah, it's the only way.

Gen. O'Neill:
Can you do that?

Dr. McKay:
Yeah...If we plant charges in all 10 of the shield emitters before the Daedalus arrives, that way, when the replicators try to activate the shields...

Woolsey:
...The C-4 detonates, the Daedalus beams a warhead into the city, and we're all vaporized.

[O'Neill turns quickly to look at McKay]

Gen. O'Neill:
[Agitated] Sounds more like a plan "F", doesn't it? As in, "We're totally..."
