She didn't detect Agatha's presence. In Scotland, when that MFer snuck up and stabbed Vision, she didn't see that coming.Ok....you just making shit up right now.
Ain’t no way nobody gonna be able to sneak up behind her and grab her.
She has the ability to use her powers to protect her surroundings, you saw how she did it with Westview.
As of the series finale, Wanda right now is one of the most powerful characters out of all the characters that have been introduced so far in the MCU since Iron Man.
Ain’t nobody gonna jump out from behind a tree and catch her.
