"Sarah? Is that still you?" Karyn asked. Maybe Jon was back to normal.
Jon turned around and looked at her, then said "Uh ... why, um ... are you calling me Sarah?"
Nope, not Sarah. But it wasn't Jon either. He was way too shy to be Jon. She suddenly realized that "multiple" could mean more than just two, meaning that Jon could have dozens of personalities rattling around in his head. She hoped not. She didn't want Jon to be a minority in his own body.
But if this current personality didn't belong to Sarah or Jon, then who did it belong to?
