Spoilers for Spider-Man: Far From Home includes, so skip if you don’t want to have the movie spoiled.
Guys, don’t worry about the mid-credit scene too much. In the comics, whenever his identity gets out it always gets covered back up relatively easily or with some sort of mystical solution. Personally, I feel like a Skrull will pretend to be Peter Parker and another will be Nick Fury and Peter can be there as Spider-Man and at a conference:
Talos (as Fury): So, we’re here today to discuss the events with Mysterio in Europe. As you can see, we’ve brought both Peter Parker,
A Skrull (as Peter): *waves shyly, cuz they’re pretending to be Peter*
Talos (as Fury): And Spider-Man,
Peter (as Spider-Man): Hey everybody. *also waving awkwardly*
Talos (as Fury): And we are here to explain the situation. Mysterio, or Quentin Beck, along with a team of scientists, was using drones stolen from a Stark Tech security program and holographic technology he created to invent the “Elementals” and cause damage in order to make himself, “Mysterio”, look like a hero and try to be the next Iron Man. He even, after getting himself killed by his own hacked drones, had an associate piece together the video you saw. The clip in question, of Spider-Man ordering the drones to execute, was taken out of context and actually him ordering the program, EDITH, to cancel the drones and send them back to space. Peter Parker is simply a boy who worked as Tony Stark’s personal intern, and was on a school trip helping out with a few technological aspects during the mission. As you can obviously see, they are not the same person.
Reporters, shouting questions over each other: How do we know that’s actually Spider-Man? It could just be someone in the suit!
Skrull (as Peter): Uhhh, why don’t you...
Peter (as Spider-Man), from the ceiling: Why’d you guys think I was a teenager? *dropping back to the floor* Or a TERRORIST? Why would you think Tony would SACRIFICE himself and end up being one??
