Continuity mistake: When Sean and Claudia catch Lily doing homework in her room, and they realise that she is not actually drunk, Sean asks where she was "tonight." But downstairs, a few minutes ago, Sean commented on her being drunk in "the middle of the day."

Question: How can Sister Helen give Lily detention when she sees Lily's tongue ring? She is at the Finnerty's house. Piercings are often a violation of school dress codes, but Sister Helen has not seen the piercing while at school.
Answer: It happens. One of my middle school/junior high classmates was suspended for fighting another classmate during the weekend, at a location nowhere near the school. Also, after Jimmy and Lily created the fake image of Sister Helen, it's easier for Sister Helen to get away with assigning an unfair detention.
