Karyn, No Friend of Mine

"Huh? What are you talking about?" Jon asked. "You *know* what I'm talking about, Jon. Your sister is a bitch, and I can't be around someone like that!" Karyn screamed. Then she slammed the door in Jon's face. Jon was shocked. Could swapping Zoe's and Sarah's personalities change Karyn *that* much? Jon never thought there would be much of a difference with his friendship with Karyn in this new reality. But it seemed that there was: they weren't friends.
