Quote from Dick in The Thing That Wouldn't Die: Part Two
Dick: Mary, the mission's over. I have to go back. Mary: Well, first you tell me you're an alien, and then two days later, you tell me you're leaving Earth? Dick: I didn't say forever. Mary: Oh, so you can come back? Dick: No, it's forever. Come with me. I love you. Mary: Oh, I love you too, but... to spend the rest of my life on another planet... Dick: Mary, do you really want to start dating again? Especially at your age? Mary: Saturday, huh? Okay, I'll do it! [they kiss]
