"So, you want to do something else?" Biff asked. "Seeing as though sex is off the table."
"Actually, I was thinking of just going to the mall," Sarah said.
"Great, I'll come too."
Sarah looked oddly at him. "Really?"
"Sarah, it's not like I've never been to the mall."
"I know that, but usually when I suggest going, you want to do something else. Like hang out with your friends."
Biff rubbed his arm again. This time something caught his attention. He looked down and saw that his arm looked different, less muscular. How did that happen?
"Well?" he asked Sarah, looking up at her.
"Well what?"
"Aren't we going?"
Sarah looked at him a moment longer. There something off about him and not just the fact that he wanted to go to the mall with her. He seemed ... different. But she couldn't place as to why.
Shrugging, she left her house and Biff followed.
