Here, I made you a twin. He’s almost exactly like you, except that you are real and he is not, and that I know his mind as well as I know my own. His mind is my masterpiece, and my thoughts are his siblings. He knows my mind as well as I know his.

He plays the game of sibling rivalry. Sometimes he wins, and steals my attention away from my other creations. I know I have to play fair, but it’s difficult when he yearns for my attention as much as I do his.

I made him because he lets me play with him. I can touch him, or taste him, if I wanted to. I would play with you, too, but I don’t know if you’d let me. And even if you did, I would not play with you if it were detrimental to how well you play your other games. I think we both know that it would bring harm.

So, I made you a twin to protect your trade. As long as I think he’s you, I cannot harm you. But even though I think he’s you, it’s hard to think you’re him. I can’t help it, but though your twin is in my mind, it’s still you who’s in my fantasies. And it is this that will be the death of me!
