Yes, But Let's Leave Steve as Other Steve

A quick look between your shoe and Mark, you drive the image of Mark into your head and intentionally shoot this time.

Flash.

You are back to your normal Mark self, watching the game with gun in hand. Listening to the apartment, you could tell Steve was taking a violently loud dump. It was mostly in protest to having been **** to clean the apartment over the bet, but he wouldn't intentionally make a mess that he would then be **** to clean up once again.

You fixed the image of Steve in your mind again and shot yourself only to find yourself wiping your ass with the gun under your armpit.

Another refreshed image of Mark and you were back watching the game.

Logically, if you were Mark, Steve couldn't be Mark, so he would be Steve.

Inversely, if you were Steve, Mark couldn't be Steve, so he would be Mark.

Well seeing as he did so well cleaning, you shot Steve one more time after he left the bathroom. You had the image of Other Steve but altered it slightly. He was now 80lb. lighter, but was still trying anything to loose that last 30lb of fat.
