Doc: "I've come to say goodbye."
Clara: "Goodbye? Well, where are you going?"
Doc: "I'm going away, and, well, I'm afraid I'll never see you again."
Doc: "Clara, I want you to know that I care about you deeply, but I realize I don't belong here and I have to go back where I came from."
Clara: "And where might that be?"
Doc: "I can't tell you."
Clara: "Well, then wherever you're going, take me with you."
Doc: "I can't Clara. I wish it didn't have to be this way, but just believe me when I tell you that I'll never forget you and that I'll love you."
Clara: "I don't understand what you're trying to say."
Doc: "Clara, I don't think there's any way that you can understand it."
Clara: "Please, Emmett, please. I have to know. If you sincerely do love me, then tell me the truth."
Doc: "All right, then. I'm from the future. I came here in a time machine that I invented, and tomorrow I have to go back to the year 1985."
Clara: "Yes, Emmett. I do understand. I understand that, because you know that I'm partial to the writings of Jules Verne, you concocted those mendacities in order to take advantage of me! Oh, I've heard some whoppers in my day, but the fact that you'd expect me to entertain a notion like that is so insulting and degrading. All you had to say is, I don't love you and I don't want to see you anymore. That at least would've been respectful!"
