The multiverse is a complicated concept to bring into the MCU, but the massive franchise has earned it at this point. And it's going to factor heavily into Spider-Man: Far From Home, which is the final installment in Phase Three. The newest trailer revealed that Jake Gyllenhaal's Mysterio was from another dimension, with the snap causing a tear in the multiverse. So it'll be fascinating to see how this type of storytelling moves the property forward, and if those tears become a recurring event in Phase Four.
