"Don't worry, we can cancel the transformation." Sean said.
Jay sees the Chronivac, he heard about it. "Fuck you guys, you're kidding. Undo this now!"
"Being black looks pretty good on you. Don't you want to stay like that for a few days?" They tell him laughing.
Sean explains the "Reality alteration" function. It makes everyone believe that Jay always looked like this. He could then have fun with that body for a short time without shocking anyone. Jay thinks about it but his roommates do not wait for his answer. Click. The Space start to vibrate and Jay is now alone in his room. From now on, he's the only one who knows he was a white man before the Chronivac created this new reality.
Jay finds his two roommates sitting in the living room. They look at him in astonishment "Damn Myles, put on your underpants!" Jay is looking for the Chronivac. Unfortunately, they do not know what he's talking about. Like everyone else, Sean and Dan's memories has been altered. And in this reality Sean did not order the Chronivac.
Without the device Jay realizes that he can no longer undo the transformation. Scared, he's stuck in this body. In this reality Jay was born black and everyone knows him that way. He realizes this by browsing his phone's photos now showing him as black man. He goes back to the bathroom to look at his reflection. "Myles ... will be hard to get used to" He looks down and ... sees his feet "Ok fuck! Six toes! Assholes!"
