This is the first Halloween episode of the series.
Unlike future Halloween episodes, this one doesn't have a spooky opening.
This marks the first time where a character's death is not caused by any characters.
This is one of the few episodes where a character cries because of another character's death. Most of the time when someone dies the characters are surprised/shocked for a little while then they forget about it later, they shrug it off/ don't care, and sometimes they leave and act like they had nothing to do with the character they killed.
