Edith Keeler: I still have a few questions I'd like to ask about you two. Oh, and don't give me that "questions about little old us?" look. You know how out of place you are around here.
Spock: Interesting. Where would you estimate we belong, Miss Keeler?
Edith Keeler: You? At his side, as if you've always been there and always will. (to Jim) And you... you belong... in another place. I don't know where or how. I'll figure it out eventually.
Spock: I'm finished with the furnace.
Edith Keeler: "Captain." Even when he doesn't say it, he does.
