I mean is it that far fetched Wanda/s reality altering powers is doing those broadcasts along with the weird tech stuff that you're seeing? Cause thats just what I'm thinking in all of this. Unrelated but the marketing for the continuing episodes of Wandavision make it seem like there will be a clash between the two(Wanda v Vision).Some other points;
A> Whatever's going on in Eastview, it's broadcasting. That's weird.
B> Something's editing that broadcast. The SWORD team aren't seeing scenes we've clearly seen inside. They made a point of stating this outright so it's not just shoddy editing or something. This not only means there's an editor, but that they know about the broadcast, that it's intentional and not a glitch. Why?
C> When Monica got ejected, that had all the hallmarks of the Scarlet Witch and her powers, red smoke and all. Nothing else we've seen has that appearance. The border of the event looks like static or digital distortion, none of the rewinds had any trace of Wanda's magic, etc.
