Ewwww, Ultimate Jess? That is super weird. A)She's a clone of his Ultimate Peter, so.... It'd basically be 616 Peter dating himself, in alternate universe clone form. Also, Ultimate Peter, and by extension, Jessica Drew is only like... 18, at the very oldest. Maybe 19, since they did the year skip. But isnt 616 Peter like, 28? That whole thing screams wrong!
