Jon thought about what Karyn said, then decided to restore the house. When he made his wish to create the Reality Editor, he made sure that he could remove objects from reality as well as people, but he always just intended to use it on people.
He pressed RESTORE and then MCMILLAN HOUSE. Suddenly, everything came back. The house, the manicured lawn, the driveway, Sarah's car.
"Jon! Look out!" Karyn yelled. She was standing on the McMillan's lawn. But Jon was still standing on the edge of the road. When reality was changed back, everything returned to how it would be a few minutes after Sarah (and yes, it was Sarah who was leaving the house) left her house.
Before Jon could make a reaction, the car hit him. The car squealed to a halt and Sarah got out, yelling at him for darting in front of her car. Fortunately, she wasn't driving fast, but Jon was hurt enough that he couldn't move.
"What's this?" Sarah asked, bending down and grabbing an odd-looking gun. "Were you going to shoot me?"
Jon opened his eyes at the sound of her voice. When he saw what she was holding, he eyes shot open even wider. "Don't ..." he croaked. He had trouble speaking.
"Don't what?" she asked, fumbling around with the device.
