Trivia: At the beginning when walking through town, Quinn (played by Jerry O'Connell) says "where's Wes Craven" and Rembrandt says "what is this, Scream 3?" Jerry O'Connell was in "Scream 2", which was directed by Wes Craven. At the time the episode aired, "Scream 3" had not been produced yet.
Chosen answer: Quinn's brother was going to be a recurring character, so "introduced" in this case referred to the actor becoming a semi-regular.
