The opening credits for episode six seem to be a tribute to Malcolm in the Middle, which ran for seven seasons between 2000 and 2006.
The entire Wanda and Vision family wear their comic book character costumes for Halloween.
There's another reference to Thanos's snap as Director Tyler Hayward talks about dealing with the repercussions of all the people "who left."
The terrifying Yo-Magic commercial seems to foreshadow Vision's future. Even though Wanda was seemingly able to bring Vision back to life, it looks like he won't stay alive for long as it's implied that he can't exist outside of the Hex later in the episode.
Blink and you'll miss the fun Disney movie Easter egg on Westview's movie theater. The sign outside the theater shows a double feature of The Incredibles andThe Parent Trap. Connecting right to Wanda's family, The Incredibles is about a family of superheroes, while The Parent Trap is about a pair of long-lost twins reuniting.
Wanda's changing accent has been brought up countless times by fans, and in episode six, Pietro makes a slight reference to it when Wanda asks, "What happened to your accent?" to which he quips, "What happened to yours?"
There is another reference that Agnes is actually Agatha Harkness as she is spotted wearing a witch costume on Halloween.
It appears that Vision has no memories pre-Westview, as a conscious Agnes tells him he's one of the Avengers, and he has no clue what she's talking about.
The episode further hints at Monica's powers as Darcy confirms that the Hex rewrote her cells on a molecular level.
A few interactions between Pietro and Wanda have fans wondering if he might actually be Mephisto in disguise. Not only is he fully aware about Wanda creating Westview, but he makes several references to the devil and hell throughout the episode.
