Trivia, Quotes, Notes and Allusions
Spock: An incredible experience, Captain. I find this scientifically fascinating.
McCoy: At least I have the good sense to be scared, Jim.
Lucien: Ah, humans. Lovely, primitive humans. Can't you do anything right?
Lucien: This isn't easy, you know. Holding us together like this, it's not even natural.
McCoy: Being in one place is very natural where we come from.
Spock: I find this all quite absorbing, Doctor.
McCoy: Probably because you're not very natural to begin with, Spock.
Spock: Lucien, you alone of all those here do not seem to fear or hate humans. Why?
Lucien: They are like me. With questions to be answered, with minds that range outwards, boundless. But every Megan is always alone in his sphere of knowledge. Humans are always together. They share. That is why I adopted your ship when I saw it arrive.
McCoy: You think Lucien really was the demon some men call Lucifer?
Kirk: Does it really matter, Bones?
Spock: It just might, Captain. If he was, this would be the second time Lucifer was cast out. And thanks to you, the first time he was saved.
