Earth 42 seems like a dark timeline overall...there's no Spider-Man and crime is running rampant with the Sinister Six running everything. So maybe in that reality The Prowler actually is a dark hero or anti-hero who is trying to battle the Sinister Six because they are responsible for the death of his dad? So maybe the next movie is Miles helping Miles-42 in one universe and then Miles-42 helping Miles to save his father in the other.

Also - since Miles-42 was SUPPOSED to become Spider-Man but the spider didn't bite him, maybe he ends up becoming Spider-Main in Earth-42 anyways and that ends up fixing the canon event issue that Miguel was so worried about.
