Clark: What happened?
Lois: The sun just blacked out. But why?
Clark: Good question...
Lois: Yeah... but it will make an even better story! C’mon – this could be our lucky day.
Perry White: Jimmy! I’m in a give orders mode, not in a discuss mode. What kind of mode are you in?
Professor Daitch: Nightfall is approximately seventeen miles across, traveling at close to thirty thousand miles an hour.
Superman: You told Kent and the other reporters that much at the news conference. Why am I here?
Professor Daitch: If my calculations are correct, in a little more than four days it’s going to hit the Earth. The sky, literally, is falling.
Superman: I guess we’re about to find out what my limits really are.
Lois: How do you feel?
Superman: This... will work.
Lois: Why are you so sure?
Superman: Because it has to.
Ground Controller: This is EPRAD Control. We have lost transmission with Superman.
Professor Daitch: A rather large portion, about three miles across, remains on a collision course with Earth.
Clark: We’re... friends, right?
Lois: Sure we’re friends.
Clark: Are we... more than friends?
(Jimmy and Clark visit a psychic to learn where the vanished Superman might be.)
Jimmy Olsen: We believe this was Superman’s. We’ve had it analyzed; it’s emitting very weak cosmic rays, which means it’s been in space.
Psychic: I have been feeling Superman’s presence strongly.
Jimmy Olsen: Oh, so he’s alive?
Psychic: I don’t know. I feel his confusion. Often the recently dead are quite rattled by the experience.
(Lex shows Lois his underground bunker, in which he proposes to stay during the impact of the Nightfall asteroid.)
Lex: I’m offering you a chance, Lois. To become a passenger on this ark. To be my special guest on mankind’s next great adventure.
Lois: If what that asteroid does is destroy the world as we know it, then I have to be there to see what takes its place.
Jonathan Kent: (To Martha, as he picks up a ball bat.) He needs proof. (To Clark) This is going to hurt me more than it hurts you, believe me. (He swings the bat at Clark as hard as he can. The bat shatters against Clark’s stomach; Jonathan winces.)
Perry White: (about Clark) Maybe he’s the lucky one in all of this. If he can’t remember how it was... how’s he going to miss it?
Lois: (about Superman) The thing you notice most about him is how much you can count on him.
Ground Controller: Mission trackers reporting an anomaly. Switching to backup computers for corroboration... Roger, confirmation, asteroid velocity is decreasing... The asteroid appears to be reversing course... we are stopping the countdown clock at this time...
