True....but maybe there is some truth being told in jest here? Perhaps even if they're not allowed to convey it on the page or go too far "there", Marvel writers do sort of headcanon RYV Peter and MJ as being versions we grew up loving...that's what I got from the deja vu incident in 2016 from Slott
Also keep in mind that one of Bendis' long-running story arcs in Jessica Jones involves reality-displaced people who remember entirely different lives and are now living equally different ones.
