First, thoughts on WandaVision episode 5.
LOVED IT! I hope the amazing episode doesn't get totally eclipsed by the ending. It's a very cool ending and could mean a multitude of things, but the rest of the episode was incredible. I loved when Wanda broke back into her Sokovian accent when talking to SWORD. Subtle character move. I loved when Vision fought through the end credits and really went head to head with Wanda. It shows she really can't simply control him or else she would have. Best acting by the two of them thus far I think. The Agnes scene of her wanting to start from the top, I think, hints at her having a huge role behind the scenes. Which they've alluded to in a bunch of others ways too. My theory is that she and maybe some others offered Wanda a way to get Vision back using her reality warping powers but Wanda proved too powerful for them and took over to some degree. I also think they (whoever they are) are trying to get the kids and they're the whole point of it. Many other thoughts, but that's the bulk of them.
Second, I don't think anyone is officially confirmed for Spidey 3 execept Jamie Foxx as Electro and Dr. Strange. The rest are a ton of rumors and people simply claiming to have been confirmed. But, best I can tell, none of the other Spider-Men have been confirmed. So whether or not Tobey, Andrew, etc etc are in it is very possible but definitely NOT confirmed.
