Biff was compelled to look at his watch, as reality shifted around him. The watch let out a bright light as it deflected some of the stone's magic from him. Unfortunately, it didn't block everything. It just prevented Biff's memories from changing to fit the new reality.
For a moment, Biff felt very dizzy. The room felt like it was spinning and changing around him. The thing was, though, it really was. That was reality shifting.
When his dizzy spell was over, he got embraced from behind, presumably by Sarah. But when he turned to kiss her, he nearly jumped away. "Wh-who are you?" he stuttered, pushing her away from him.
"What do you mean? You don't recognize your own girlfriend?" the very butch girl asked.
Biff squinted and realized that this girl really was Sarah. But ... she looked so butch. Her hair was short, her clothing baggy and manly, she didn't even wear any make-up or earrings or anything. And she also had tattoos. What the hell happened to her?
"Maybe you'll recognize me more if I do this," she said, leaning towards him and placing her hands on his breasts, causing a moan to escape his soft lips, right before she kissed him.
Hold on ... breasts? Soft lips?
Biff broke the kiss and looked down, then screamed.
"What?!" Sarah said, startled.
"I ... I ... I'm a girl!"
"Well, duh," Sarah said. "Like you could ever be anything else, Buffy."
"Buffy?" Biff uttered. What was happening? Could all of this have anything to do with that watch? It was glowing right before everything changed, after all. If so, was there any way to change things back? Or was he stuck as a girl for the rest of his life? Her life.
