"I think they spotted us. Kyla's coming over here right now. What ... what do we say?"
Sarah wasn't afraid of Kyla so much as Jay...although Kyla could easily tell Jay to beat the crap out of her. She didn't know what Biff was so afraid of...She was the one in physical danger.
Sarah had to admit that Kyla was hot. Tight t-shirt, miniskirt, heels... "Are you following us?" Kyla demanded.
"What? No," Biff protested weakly.
It was at this point that Molly sprinted past, chasing the cloud to the last part of the mall to close...the Food Court, which was where the four were standing outside of.
