Mikey opened the bathroom door and saw Jenny Downing standing in the bathroom.
"Jenny? When did you come over?"
"I'm not Jenny."
"Oh. Sorry Jessica. You two look identical it's impossible to tell you apart?"
Jessica? Jon thought. But then he understood. Jon had wished to become Jenny's twin. But the stone didn't make him Jenny's twin sister, Just someone in his own family who by a coincidence looks identical to another girl.
"It's alright Mikey I know it's hard to tell"
"Impossible you mean, your identical down to birthmarks, how weird that my twin sister would look just like my girlfriend.
"twin sister!" Jon thought but it made sense he had to be Jenny' age which was near Mikey's age so they must be twins.
Jon left the bathroom to see how her life had changed
