20 Easter Eggs From Spider-Man: No Way Home You May Have Missed
5. MJ Has Always Been MJ
One of the bones of contention many had with Zendaya's MCU version of MJ was that she wasn't 'reallllllly' MJ. Yeah, those were her initials, sure, and she was a great foil and match for Peter, but she wasn't MJ in the traditional sense.
No Way Home put that falsehood to bed.
During the scenes when Ned, Peter, and MJ were being interrogated by Damage Control, it was revealed that MJ's full name was Michelle Jones-Watson. She replies that she only goes by Jones, not using the Watson part of her name.
However, this definitively makes her MJ Watson, lining her up with traditional MJs across the multi-verse of the last 60 years of Spider-Man.
Case closed.
