Tara bullies Chrissa by bumping into her, then sticking her with a pen when no one else is watching. Chrissa is upset, and ends up going to the bathroom to inspect the damage. While in there, Tara takes the envelope she was supposed to bring to the office and does it herself to embarrass Chrissa.
At dinner, Chrissa is told her "friend" (actually one of her bullies) is at the front door. She explains that she is "supposed" to apologize for being mean to her. She says she is sorry, but she obviously doesn't mean it.
