(Wanted to expand a bit here. Also, not sure even at Sarah's new perceived age a security guard would approach unless she seemed lost.)
Biff wasn't going to complain. As they started to leave, they nearly bumped into Sarah McMillan.
This was the first time Mikey had seen Sarah. He took in the teenage girl with the short brown hair, the short ragged fingernails, and the t-shirt with the cartoon character on it, the scuffed up sneakers...He frowned for a moment. This girl seemed so similar for some reason.
"Watch it, dork," Biff said.
"Sorry, Biff," Sarah said, looking down.
That satisfied Biff and he took Mikey's arm and led him out.
Sarah was really annoyed now. First they wouldn't shut up, then they bumped into her, then Biff had demanded an apology. She was glad that they were leaving so she could finally enjoy the movie.
Once the movie had ended Sarah left the theatre and was just wondering what to do next. She headed toward the video game store in the mall.
