I don't know who "Kiki" is.
Anyway, I have no idea how true this is, but I've heard it said more than once that "MJ" in the Holland films was never actually supposed to be Mary Jane Watson... as stupid as that sounds. (She's actually credited as "Michelle" in the Homecoming IMDB page
here)
What I'm about to say may or may not actually be true, and it might actually be a spoiler, so I'm spoilering it:
I randomly read somewhere that the end of No Way Home will end with *everybody* not only forgetting that Peter is Spiderman, but also forgetting about Peter entirely (but still remembering Spiderman somehow). Including both Ned and "MJ". The thing I read also purports that Ned and "MJ" end up together because they both forgot about Peter. I am not claiming any of this to be fact, It's all something that I read elsewhere and it may or may not be true. Also, Aunt May is supposedly killed in this film.
