They headed back to Mikey's house to clean up and get to school.
Mikey felt confused still, and sat in his bedroom, getting out his magic supplies, and drawing a spell on the floor with masking tape, and lighting a candle.
There was something going on he wasn't sensing. The spell would give him greater clarity. The spell flared into being, and went up against the wish...which was far greater magic, the way it had happened before.
Like a chemical reaction, the combination of the two caused a flareup...a more intense magical effect.
It had the effect of speeding up the wish affecting Mikey. The little boy dressed in the clothes of a teenage girl shifted, expanding outward in a rapid manner, until a fourteen year old girl lay on the ground, clutching her head.
Michelle picked herself up. She felt more clear-headed about what had happened. Her little brother had been replaced by an old woman. Her real little brother...the name Sarah came to mind, had walked off.
