Trivia

 * This is the only episode whose title doesn't come from a line spoken in the episode itself.
 * This episode brings the series episode count to 27. This is unusual, because most weekly syndicated shows are planned to have multiples of 13 episodes, since that divides evenly into a 52-week year. This suggests that a recap episode was added late in production, perhaps prompted by concern that weekly viewers might be confused by the second arc if they couldn't remember important details about the first one.
