Oh man, so many thoughts about this episode....
For one, I always had a feeling that the situation in Westview was one Agatha happened upon or maybe was caught up in. It seemed too obvious that she played some kind of key role of the creation of the hex or something along those lines... Of course, I mostly dismissed my initial theory because of the show's clever misdirection. Sneaky writers 😃 ...
Ugh, I am kicking myself for not even considering that Hayward's "footage" of Wanda's "attack" on SWORD was tampered with. Duh. I mean anyone can edit surveillance if they have the right tech, and he didn't even do that really. He just presented it with fake context and misdirection.
I must admit that the reason Westview is the site of the hex, that Vision and her were going to build their house and life there, was surprising and touching. It seems very plausible and makes the story more poignant.
So many more angles to this story, I definitely need to rewatch this episode.
