- Narrator: [epilogue] Even as we watch, the spaceship Jupiter II is drawn deeper and deeper into the gravitational pull of the unknown planet. Whether its alien environment will be friendly or hostile, whether this will be the beginning of a new adventure for the Robinson family or the end of everything, only time will tell...
- [With John and Maureen passed out from the heat of an approaching comet, Don struggles to open the jammed hatch door and pull them inside]
- Dr. Zachary Smith: I hope you children are more familiar with the navigation of this ship than I am.
- Will Robinson: Why?
- Dr. Zachary Smith: Well, if the heat out there should affect our pilot...
- Will Robinson: [angrily] D'you always have to say things like that?
- Dr. Zachary Smith: Calling Aeolis-14-Umbra. Aeolis-14-Umbra. We have sighted your spaceship. Do you have instructions?
- [the Jupiter 2 comes upon a gigantic alien spacecraft]
- Prof. John Robinson: [his curiosity piqued] Let's get around to the other side then.
- Maj. Don West: [not keen on the idea] All right, if you insist.
- Prof. John Robinson: Well, LOOK at that thing! Where's your scientific curiosity?
- Maj. Don West: All in one basket - Alpha Centauri
- [the robot won't obey]
- Will Robinson: [imitating Dr. Smith] Two steps forward, my mechanical friend.
- [the robot obeys]
- Will Robinson: [seeing Dr. Smith raise his gun] No! Don't shoot! He was in that thing. I disturbed him. I think I can communicate with him.
- Dr. Zachary Smith: [horrified] Not human! Nothing! And I was so sure.
- Will Robinson: Human? Out here? Billions of miles from the Earth?
- [Smith raises gun]
- Will Robinson: No! Don't! Maybe they can help us. I mean, they're not like us, but maybe they are.
- Dr. Zachary Smith: Very well, my boy. See what you can do.
- [the roused alien gives off an electrical discharge, quite possibly its manner of communication]
- Dr. Zachary Smith: What do you suppose THAT means?
- Will Robinson: I don't know. I don't think it likes being asked to guide us anywhere.
- Dr. Zachary Smith: Let me try.
- Dr. Zachary Smith: [to alien] Uh, we are from the planet Earth. Uh, we're perfectly willing to stay here if you show ME how your guidence system can get us back there.
- Will Robinson: But we don't WANNA go back there to Earth, Dr. Smith. We wanna go to Alpha Centauri.
- Dr. Zachary Smith: YOU do. Not I. Doesn't really mater. It doesn't seem very cooperative.
- Will Robinson: He WAS before YOU got here.
- Dr. Zachary Smith: Very well. Try again. And I hope you realize how important their guidence system would be to us.
- Will Robinson: [to alien] My parents are on the Jupiter 2 spaceship, and my sisters and Major West - he's our pilot - and Dr. Smith here... well... he just seemed to be aboard when we lifted off.
- Dr. Zachary Smith: He's not intersted in your passenger list. Ask him something sensible.
- Will Robinson: I can't ask him ANYTHING until I get him to realize I don't mean him any harm!
- Will Robinson: [to alien] We are friendly. We're from the planet Earth. We are on our way to Alpha Centauri.
- Dr. Zachary Smith: No, no, no! Back to Earth!
- Will Robinson: He doesn't seem to read me no matter WHAT I say.
- Dr. Zachary Smith: He'll read THIS!
- [Dr. Smith shoots the alien]
- Will Robinson: You've ruined EVERYTHING!
- Maureen Robinson: We have no BUSINESS trying to land on that planet!
- Will Robinson: Oh, Mother.
- Maureen Robinson: We're settlers, not explorers! We have a specific destination to reach!
- Narrator: [prologue] Last week, John Robinson, father of the first family to attempt colonization of outer space, found himself helplessly adrift when his line snapped while trying to repair navigational equipment. It is now shortly thereafter, as Maureen Robinson desperately tries to reach her husband before he drifts further off into the trackless void of outer space.
- Will Robinson: [John, Don, and Dr. Smith are leaving Jupiter 2 to explore an alien craft that has enveloped them] I don't see why Dad wouldn't let me go with them.
- Maureen Robinson: We do need a man here while they're gone, Will.
