Looks like they went with Malcom in the Middle as the basis for the sitcom in this episode. Kinda expected something more 90's for this episode, as that show started in 2000, but the themes of that sitcom works well for where this show is currently at.
It's interesting Wanda said her Halloween costume was based on a Sokovian fortune teller, which is a bit controversial, given the Romani heritage the character has in the comics. And Vision's costume is apparently meant to be a based on a Mexican Luchador. Creative way to justify the comic book inspired Halloween costumes in this setting at any rate. Billy's costume is also like his comic book counterpart. Seems odd that Tommy shares Quicksilver's costume, rather than something that mirrors his own comic book counterpart.
We get confirmation that Monica Rambeau's cells have been changed as a result of crossing through the barrier, twice. Tyler Hayward is definitely up to something that seems to be focused on Vision specifically. Given they mentioned in the previous episode Vision's body had been in a S.W.O.R.D. facility, I'm betting they discovered something with his body that they want him back to continue to research. I like that he cites the struggles following the Snap in his argument with Rambeau in how to deal with this situation with Wanda, showing us why his view is a lot more reactionary.
The commercial in this episode is... Odd, even as far as other commercials in this series have been. Others have appeared to be references to some trauma in Wanda's life, but I'm not sure what "Yo-Magic" is referencing.
