From the information that was coming into his mind, part of the way he worded the wish didn't tie up any loose ends which created a loophole that had the wish continuing even though that Japanese girl had taken Jon's original identity.
"Ok so now that that's out of the way I need to find out who's being affected now." Mikey said to himself quietly as his grip on the stone tightened. "I wish to know who's currently being affected by the results of the wish I made to my brother." he said when he felt the stone grow warm in his hand.
A vision entered his head of a grown man that he had never seen before but was told that his name was David McMillan and saw in the vision the man begin to take off his clothes in what appeared to be a girl's locker room at a high school as the outfit he replaced his previous one with was that of a cheerleading outfit.
David then put on some makeup and suddenly whatever fog he was under had lifted itself and with a smile and vapid expression on his face, he slung his purse over his shoulder and strutted out towards his next class.
Mikey focused on this vision for a bit before reality struck him. "Mikey are you paying attention?" Miss Zoe Warren asked.
