Oh my, you are melodramatic and I thought I was. But clearly, as in the comics, there is always some 'deux machina' and that will be Dr. Strange coming in at the end and casting the spell that will heal and repair the damage and make them forget.
And whether that seems morally off and wrong, it would happen because it has so many times in comics, even Professor X wiping memories, without repairing other things.
[that's not an attack on him, just saying he is no magic person like Strange]
So I think reasonably we will find that Wanda didn't exactly do this thing, that maybe some of it is Agatha (all along) or whatever/however.
Certainly Strange will show up because he senses the great magic thing happening in Westview.
I think we've all mentioned these possibilities plus continuity wise, where would that Mordo be? He could be Norm, maybe, lol (not - just kidding). Of course Mordo being back for years with others snapped, or recently back could have changed his perspective?
No I think not only is Wanda 'innocent' but she will be seen as innocent, one way or the other.
