I suppose it's a given when speculating to say "it could be this...but also this", but it was still kind of funny to read the quotes.
I also think they'll save Monica unleashing most of her powers for Captain Marvel 2. But, that she does have powers at this point. I don't think she's going to gain them in that movie so much as awaken them. With the test results I don't think it's possible that she doesn't have anything unusual going on inside of her right now.
The Quicksilver thing is honestly interesting. Since it really could go either way. Either he's from multiverse and being controlled as well or it is someone like Mephisto pretending to be him. I kind of lean towards the former. But we'll see. I am curious if they'll just port over most of the X-Men for this or still make their own MCU X-Men. After all just taking them over would mean leaving no X-Men in their own native universe. Unless we're talking universes merging or something.
Hayward will be worth keeping an eye on. After all he could be mostly on the level. But...could just be evil as well. Be a real hit for Sword to also have corruption right at the top after what happened with Shield. But if he is up to something it would free up that leadership position for Monica...
