COCHRANE: I can't take her away from here. If I do, she'll die. If I leave her, she'll die of loneliness. I owe everything to her. I can't leave her. I love her. Is that surprising?
SPOCK: Not coming from a human being. You are, after all, essentially irrational.
KIRK: Think it over, Mister Cochrane. There's a whole galaxy out there waiting to honour you.
COCHRANE: I have honours enough.
SPOCK: But you will age, both of you. There will be no immortality. You'll both grow old here and finally die.
COCHRANE: That's been happening to men and women for a long time. I've got the feeling it's one of the pleasanter things about being human, as long as you grow old together.
KIRK: Are you sure?
COCHRANE: There's plenty of water here. The climate's good for growing things.
I might try to plant a fig tree. A man's entitled to that, isn't he? It isn't gratitude, Captain. Now that I see her, touch her, I know that I love her. We'll have a lot of years together. They'll be happy ones.
