An interesting story - though I'm wondering why just Gary was brought before the machine. Or has John gone after the others who tormented him in high school?
Also, I wasn't quite sure why the now-female Gary seemed to regain his memories while John lost his knowledge. Seems a bit random - but it's your story to tell.
The story could easily be extended to show how Gary copes with his (or her) new life.
