Sumner (over radio): Doctor Weir. Colonel Sumner. Can you come down and meet me, please? We're three levels down from you.
Weir: (into radio) Right away.
(Weir and Sheppard make their way down to meet with Sumner.)
Sumner: We've only been able to secure a fraction of the place. It's huge.
Weir: So it might really be the lost city of Atlantis?
Sumner: I'd say that's a good bet.
(Sumner leads them towards what he wants them to see. Weir stares in amazement.)
Weir: Oh my God.
(Sumner has brought them to a large window. The city lies under water.)
Weir: We're under water.
(They gaze out of the window.)
Sumner: I'd say we're under several hundred feet of ocean. If we can't dial out, this could be a problem.
McKay: Colonel. Doctor Weir.
Sheppard: (to McKay) We're under water!
McKay: (walking over to join them) Yes, I was just, uh, coming to tell you. Fortunately, there is some sort of a forcefield holding back the w...water. (stops and stares at the sight out of the window.) Oh, that is impressive, isn't it?
