By coincidence That Guy is also working on something that... might be their group project? It's not super-clear. There are a lot of circles and arrows drawn between circles and question marks and everything is named things like "K3" or "LL" or "~*~". 

It's either a really weird approach to the Great Gatsby or homework for some class Sasha is too stupid and too Spiderman-y to be in. 

That Guy seems like he knows what he's doing; if he wants to do his (....math? people do stuff like that in higher math, right? or maybe it's programming, who knows) homework in English class Sasha will trust him. And keep working on his history questions, which he is mostly bullshitting based on half-remembered anecdotes. 

By the end of class his hands are shaking and he almost falls over when he stands up. 

As he walks up, he opens up a pack of Reese's Pieces and shoves them mechanically into his mouth. 

....this isn't the route Sasha usually takes to his next class but it's whatever. And there's free apples and stuff at the cafeteria, it's not like he'll be hungry if he gives That Guy.... whose name he still doesn't know.... his food. He hurries to catch up to him on the way out. 

"Are you okay?" 

"Uh. Yeah?"

That Guy looks profoundly uncomfortable. 

"Okay. I, just, um. Have food? If you want it?" 

His eyes are huge.

"Yes," he says around a mouthful of Reese's Piece. "Please."

His lunch is a sandwich and a Snicker's bar. That Guy can have it. 

They disappear in like a minute flat. 

"Sorry, it's a medical thing," he says. He looks noticeably less shaky.

"It's fine, I'm glad you're okay. 

— I should get to class, probably. See you." 

"Yeah. See you." 

As Sasha leaves, That Guy takes an Ensure out of his bag and drinks it in a single gulp.

Yeah, he's just... not... gonna interact with that. 

School is school. He takes the subway home, drops off his backpack, and heads for Central Park on the subway; halfway there he gets off the subway, suits up, and swings the rest of the way. Do they in fact need Spiderman there, as opposed to Literally Anyone Else Who Is More Equipped To Survive A Death Trap? 

Doctor Octopus has a loudspeaker!

"If Spiderman doesn't turn himself in to me in the next hour," he says, "the bombs under the Met will go off!"

Wow, that's blatant. 

He really hopes they're evacuating the Met, just in case. 

"What's this about bombs?" he says, all casual, from a wall twenty feet above Doc Ock's head. 

"You've thwarted me for the LAST TIME, Spiderman!"

"You say that a lot," he observes. 

Instead of a response, Doc Ock roars and tries to hit Spiderman with one of his arms.

"It does kinda lose its punch after a while."

Bullets.

He takes a few shots for the base of the offending arm – and one for the head, but the stupid headshot never hits the first time with recurring villains.

DId he really expect that Doc Ock's arms wouldn't be bulletproof?

Doc Ock catches the headshot bullet out of the air.

Once there aren't any bullets flying around, this seems like an excellent moment to swing over to a different building. Perhaps one further away from Doctor Octopus. 

"You know New York is big, right?" he says, still false-casual. "What if I'd been in the Bronx? Were you seriously going to bomb the Met if I couldn't hear you from the Bronx? You weren't even gonna try to send an email?" 

Doc Ock chases him to the next building. "I was going to give you twelve hours but your little friend at the fansite gave you some warning."

Yeah that's pretty much how he figured the opening salvo was gonna go down.

"Yeah, about that – I heard there were gonna be death traps? And if there aren't I'm gonna need to ask for a refund."

More bullets. Aiming for the squishy bits this time.

"I'm kind of offended that you think I'm the kind of person who reads my own fansite," says Sasha, who absolutely reads his own fansite. Over here is a building that looks like it's already been evacuated, how about he goes over here. 

It maybe should have been predictable that the building without any people in it would instead have a robot that would grab Sasha and throw him into Deathtrap Type #2.
