Will Robinson
- Will Robinson: [appraising Nerim's cosmonium] It looks like you've got little bits of sun there, Mr. Nerim.
- Dr. Zachary Smith: Don't be ridiculous, Will. What possible use could there be for "little bits of sun?"
- Nerim: Well, the boy's smarter than YOU are, Zack boy. "Bits of sun" is just about what this is - quintescence of the living force that thaws the ice and melts the snow and puts living breath in everything that grows. That's a sight more precious than diamonds, ain't it, Zach boy?
- Will Robinson: [to John] And don't worry about Dr. Smith. I'll take care of HIM.
- Dr. Zachary Smith: [witheringly] What a comfort you are in my hour of need.
- Dr. Zachary Smith: You, uh... you will bear me out, won't you, Will, when I tell them that I meant no harm? It was just, uh... It was just a vagrant impulse.
- Will Robinson: [irritated] You have to explain that yourself. I don't know what a vagrant impulse means.
