He started the car and was going in the wrong direction. She paused. He must be taking her back to Sarah's place. All her stuff was there...but she just wanted to go home...
In the end Karyn decided not to say anything to Biff. She just wanted out of this date, and Sarah still had her things.
When they got to Sarah's house, Karyn got outo f the car and Biff waited until she was inside. She knocked on the door. There was no answer. She tried the door and to her surprise it opened.
"Sarah!?" Karyn called out. Still no answer. Sarah's parents weren't home. Sarah had said something vague about them being on a business trip.
Sarah wasn't in her room. She couldn't find wher own things, so she changed into something of Sarah's to get dry, then started to explore the house. She found Sarah in the basement, which was a home theater, curled up with a pizza...in her favorite jumper.
"Sarah?"
"Just a minute...I want to see what happens," she said, pushing the pizza box toward Karyn.
