Jon decided to go to Sarah's house. If she wasn't there right now, she'd have to show up sometime and he'd be there to catch her and the stone. But he didn't want to take his dog Karyn with him. She'd just get in the way. So, he took her back inside his house and made sure that she stayed.
Before he left the house, however, he saw his Goth sister Zoe and his mom enter the living room. They looked like Sarah too! It was weird to see Sarah as a Goth almost as much as it was to see Sarah as a nearly 40-year old woman.
He had to fix this! He ran out the door, his high heels clattering on the sidewalk, and ran to Sarah's house.
