List of The Astral Factor quotes.

Roger Sands: You're my mother.

Captain Wells: What do you think of Holt?
Lt. Charles Barrett: He's not as bad as I thought, but he's not as good as he thinks he is. I'll probably be working for him in five years.

Lt. Charles Barrett: (hears her on the guitar) You're good.
Colleen Hudson: Thank you, I'm better on the piano but of course when your parents are Norweigan and German, music has to be in the house.
