Will Robinson
- Dr. Zachary Smith: But this is home.
- Will Robinson: Suppose it's not. Suppose it's just another unknown planet like the one my parents are on. That means you and I are the only ones here and'll have to go on living here forever, maybe. I'll probably live a bit longer than you 'cause I'm not as old as you are.
- Dr. Zachary Smith: Bully for you.
- Will Robinson: What'll probably happen now is, when Don lifts off and heads back to Earth, he'll probably take you with him.
- Dr. Zachary Smith: You really think he will?
- Will Robinson: As his prisoner.
- Dr. Zachary Smith: I'm interested only in what is good for Zachary Smith.
- Will Robinson: You're telling me?
