The consequences of using the Infinity Gauntlet in Avengers: Endgame are already being depicted on the big screen, as the new trailer for Spider-Man: Far From Home revealed that the Snap damaged the fabric of reality enough to expose the existence of a multiverse.

One might think then that was part of some grand narrative design by Avengers: Endgame screenwriters Christopher Markus and Stephen McFeely, two of the key architects of the MCU’s Infinity Saga.

It wasn't. Markus and McFeely said they were not even aware of that development until they saw the Far From Home trailer this past week, according to an interview with the duo at The Hollywood Reporter.

But couldn’t the very existence of a multiverse easily introduce Disney’s newly acquired X-Men into the MCU?

For his part, Markus doesn’t necessarily believe the multiverse could explain the sudden appearance of mutants into this continuity: "Anything is possible, but I don't [know] whether you'd need that. Genetic mutation is genetic mutation. It just happens. Maybe they are already out there.”

McFeely added that he believes Marvel Studios boss Kevin Feige won’t fall back on any sort of expected version of how the X-Men could join the MCU, believing Feige will instead opt for “a real clever version of it."
