This is the concept my brain came up with.

Design breakdown:

REDRAW TIME!!

I fully believe that Deku would dress the exact same (AKA 'straight' boy with no fashion sense, cargo shorts and all)

he rushes to help, but finds a dead couple, scattered pearls and a sobbing kid, the culprit is nowhere to be found

he comforts the kid until the cops arrive, almost gets arrested for murder until the boy manages to stutter out what happened (Strangly, they listen to him. He seems to have a lot of influence for someone so young)

the boy clings to him while the paramedics check him for wounds, refuses to let go as he tries to pass him off to the older man who came to collect him (likely his grandfather, he woulders which of the boys parents was his child. poor man)

the boy convinces the man to let peter come home with them, and peter doesn't have to heart to protest the boy who looked so much like himself when-

he goes with them. after all where else is he supposed to go?

sitting in the lavish car with a sleeping boy in his lap, peter glances at the man driving, questions bubbling up his throat

he stays silent

buildings pass by, each one larger and more decorated than the last, all unrecognisable to him

he knew new york like the back of his hand, and none it looked like this.

peter starts to drift off, his spider sense wasn't going off, which meant it was probably safe. Well, safe enough.

(how long had it been since he last slept? he didn't think being knocked out by a random villain and waking up in a strange city counted)

he wakes up in a massive bed, sun pouring through the intricate windows of a room definitly not his own

he panics, jumping to the ceiling, webbing his backpack where it sits beside the bed and pulling it to him.

he's relieved the find his suit still in there, tucked beneath his med kit and camera

he's thinking of escaping through one of the windows when he hears a cough below him.

as he locks eyes with the elderly man, his memories come back to him.

the boy...

before he can think more about what happened last night, he realises something else

hes on the ceiling.

in front of the man

he quickly jumps down, already preparing excuses (how can he excuse this, he was just on the ceiling, holy fuu-) but stops when the man's face morphs from its previous shock to- was that amusement?

Peters confusion must have shown on his face, because the man chuckled, his face gaining more wrinkles than it already had (honestly that hadn't seem possible)

Then the man speaks.
