Trivia

 * In "Mei Lin Takes a Stand", Kate is the one who is more advanced and growing up faster. In this episode, it is the total opposite.
 * Just like in "Breezy Listening Blues," Brain&apos;s intelligence test is to fit different shapes into the correct holes. But this time, he acknowledges that one test is not enough for a final conclusion.
 * Kate imagines herself as a teenager differently than in "Paradise Lost."
 * When Kate is a teenager, she still is wearing her baby bow and has not a lot of hair. She would have grown more hair, and probally would have taken off the bow in real time.
 * D.W. calls Arthur a "broken baby", referring to "D.W.&apos;s Time Trouble".
