All of Jon's shouting did nothing to warn anyone of what was happening.
He was lifted up and put on a display case, still unable to make any movements, thanks to Marsha's wish. He couldn't see, hear, smell, talk, or move. He could still feel, but that really wasn't enough to feel alive. He would forever be a bra, unless someone used the wishing stone to fix his situation. But no one, besides Marsha, knew what had happened to him. And Marsha would never change him back to normal.
As Jon the bra hung from the lingerie display, Marsha walked out of the store. She looked down at the stone in her hand and smiled. She was gonna have a lot of fun with this thing.
