If this episode had been aired during Halloween last year, it would have made the holiday even scarier than it already is.
Teen Wolf does something that not a lot of shows, who features teenagers as their main characters, do these days: give the parents a bigger part within the supernatural aspect. It’s good that all the adults (at least the main ones, so Scott’s dad isn’t included just yet) know that strange things are going on in the town and that their kids are always trying to solve it.
But the bonus here is that instead of trying to convince the kids to stay out of it, they actually try to help through their respective jobs. It gives everyone, whether it’s a main or supporting character, something to do on the show.
