But, while you're doing that [fucking your clone], I did want to run one more thing by you. It's true that the clone is an exact replica of you and, theoretically, an extension of you (which is what makes the masturbation angle sound), however, you're not sharing a mind or, to be slightly more abstract, a soul, with your clone, not in the present, anyway. So, while he was at one point a perfect copy of you, the instant he came into existence, he started developing his own memories, separate from yours. By virtue of the very fact that he knows he's a clone should tell you that you're already different people. He's in the room with you experiencing life in a completely different way, interpreting the surroundings in a way that's specific to him. After even a few seconds of being alive, he's no longer your clone, he's got his own memories and experiences and opinions and everything else that informs someone's unique personality. He looks exactly like you, yes, and shares all of your previous memories, but he's not you, not anymore. He's just some guy.
