1x26 - Beverly Hills Teens

As the teacher is giving all the Teens in class some lessons about fairytales, Bianca falls asleep and has a dream the she is an evil queen and all the other Teens are other fairytale characters. The fairytales in Bianca's dream include Robin Hood, Little Red Riding Hood, Rapunzal, Rumpelstiltskin, Snow White and Sleeping Beauty. In the end, after she is kissing Wilshire in her sleep, the teacher has her punished by being locked up in a tower that looks exactly the the one in her dream.
