There are plenty of mysteries when it comes to WandaVision. Each week more and more questions are thrown at viewers and while each episode offers more clues as to what is going on with Wanda and Westview, there's one mystery that fans have been eagerly trying to solve. That mystery is who the aerospace engineer friend Monica Rambeau has referenced and while that friend's identity is one viewers will have to keep watching for, Teyonah Parris is excited for it -- and she can't wait to see fan reaction, either.
