"So where do we start looking?" Biff asked. "I mean, what we had was just a chance encounter. If we hadn't met at this house, I'd still be thinking that I'm an old woman and you'd still think that you're supposed to be a nun."
Tiffany realized that Biff had a point. They couldn't just go door-to-door, checking every place in town. They didn't even know everyone in town. How would they know if anything was different if people they didn't know had changed?
But then a thought occurred to her. "Nadine."
"Huh?"
"I remember Nadine's mother saying that she didn't remember her, even though she talked about her a few minutes before. Maybe Nadine is one of the people affected by ... whatever this is."
"Maybe. But where do you want to look for her? We don't even know what kind of person she changed into," Biff pointed out.
