As Jon left Sarah's, he heard a scream...and ran back over to investigate. A young woman in a business suit jumped out of a car parked in the McMillan's driveway. She must've been the fourth member of Mark, Barbara, and Gary's carpool. Then it dawned on Jon that while had said people who were swapped wouldn't notice the change, he hadn't said anything about anyone else. Working fast, Jon quickly swapped his body from the neck down with the young woman, and made a quick wish so that no one else would notice the changes either.
Then Jon thought of a quick follow up that while the people changed wouldn't initially notice for about an hour, and after about another hour they would swap back.
Jon absent mindedly clicked his high heels as he walked to Karyn's house.
