@PlusUltra - Get a friendly Skrull to pose as himself or Spider-Man when he’s in custody and the problem is fixed.

@Mrcool210 - LOOOLL

@Franshu - I don't necessarily feel like they're intentionally brushing off Uncle Ben. The sequence you're alluding to, much like the rest of the film, simply demonstrates just how raw the loss of Tony is to Peter at that time because it's just happened, and the pressure he feels to live up to that legacy and follow in his footsteps despite the fact he feels that he's nowhere near ready.

And as for the Peter/Tony relationship, I always got the impression that Peter leaned so heavily into having Tony as a mentor and father figure because he was trying to fill the void left by Uncle Ben's death. It's implied Ben died recently (Peter says he only got his powers a few months before Civil War - and Ben traditionally dies when Peter has already been bitten but hasn't suited up - and then in Homecoming he acts as if May's loss was recent) so Peter was presumably still in mourning when Tony, someone he must've admired beforehand as another scientifically intelligent orphan, shows up and offers to take him under his wing.

To then lose Tony as well shortly after would mean he's now doubling down on those feelings of loss and responsibility. If anything, I'd imagine his whole reason for being Spider-Man is to try and make up for not saving Ben, and in losing Tony he must feel that he's failed that, hence his immense guilt.

As for the illusion itself though, that was something Mysterio constructed, it wasn't like a Scarecrow fear toxin situation where Spidey imagined that - it was being shown to him by Beck's choosing, and Beck wouldn't have known Peter well enough to know about Uncle Ben, otherwise he definitely would've included him.

I do agree about the secret identity stuff though. They have to deal with it now that they've set it up, but Peter and Spidey always work best as secret alter-egos rather than being publicly known as the same person so I am slightly anxious about it going forward. That entire mid credits sequence was insane though, and I grinned like a child when it happened.
