Trivia

 * The Xfinity description guide calls D.W. a boy while saying, "D.W's imaginary friend Nadine is missing, so his real-life pals set out to find her".
 * Even though Kate still has the ability to talk in this episode, her regular crying was heard.
 * In the beginning of the episode, Pal breaks the 4th wall telling Kate that the viewers don't say anything even when Arthur talks to them. That is because no viewers were heard during the show (excluding And now a word from us like segment).
