WandaVision Spoiler Filled Theory POST Episode 8
! DO NOT READ FURTHER UNTIL YOU WATCH WANDAVISION EPISODE EIGHT !
Final Spoiler warning for this absolute insane theory that I think just possibly might be true.
Okay so let's lay out what we saw, Agatha Harkness is investigating Wanda trying to figure out HOW she is doing what she is doing. This line of thinking gives us three possible outcomes in my head, and no Mephisto is not one of them.
1. Agatha wants to use Wanda to bring someone back to life
2. Agatha is working for Chthon and has been trying to find the being that was imbued with his powers to bring him into this universe and believes it to be Wanda but has to investigate to confirm it.
3. My Theory, but it starts with another purple "villain"
We just possibly watched Wanda using her chaos magic CREATE another Mind Stone and Vision. Something that should not be possible, maybe still she is imbued with Chthon's power but that is probably way too much to go into on this show. So what is the purpose of Agatha being there?
Wanda, Vision, Agatha and Doctor Strange will have to team up together to stop Vision... Or should I say Ultron. Do you really think S.W.O.R.D. was successful at rebuilding Vision? Of course they were not, this is not our first super hero movie/tv show. This is how we get Ultron back in the MCU, and this time he will be here to stay. Wanda's vision in yellow (below) was purposefully "savior" like because she will become the savior of the universe helping reform the Infinity Gems. The question is will Vision be able to stay alive outside of the hex without Wanda's power holding him together, this could be the cathartic release Wanda needs to be able to finally say goodbye to Vision. But who is the cameo?
The supposed / hinted at cameo has not leaked, but my theory will be it is someone from Fox Marvel coming over. We will see the collusion of the multiverse and have it heavily implied that multiple characters have essentially been sucked over into the MCU but we will not see them all yet (Tobey McGuire and Andrew Garfield in Spider-Man 3). So who fits the bill of a "Luke Skywalker level cameo" (that Elizabeth Olsen did not actually say but was asked that question) that Paul Bettany has never worked with that they could easily have "fireworks" together. I feel like we have a very obvious answer that we know for a fact will be in MCU movies coming up but have had no confirmations as to when or how, a certain Merc with a mouth...
I believe Ryan Reynolds Deadpool will show up LATE in next weeks WandaVision finale have a quick conversation with the cast and then immediately run off as Strange tries to send him back to his universe.
