I think this is mostly what I hoped and/or figured, that Wanda would be an ally to Strange and Wong, etc.
Like many, I'm pretty tired of the spoilers and teases and speculations. I think they're mostly there to score points in various ways, likes, shares, etc.
I think they could have things like glimpses of alt realities where an illuminati exists. Just because they show a random look at Black Bolt, doesn't mean they'll explain /over-explain that to the audience. It could exist like most of the other easter eggs, but perhaps it is or will be more defining of things to come.
For the record I like Wanda being where she is now. I don't need her to have any connection now/previous/to be, as far as mutants or Magneto.
Despite some not resolved things about WV, I hope that it all leads to better for her. I don't want her to be a scapegoat, plot device or red herring.
Back to illuminati, of course it doesn't have to be anything like the comic book version. It does't have to have Prof X, Panther, Reed, etc, yet. Or keep it vague if it needs to be there for some other reasons going forward.
I doubt it will be the big part of MoM. Illuminati stuff probably belongs ranging in and out of Kang developments, imo.
