R&D is basically Peter's second home on the station, and he spends at least half his time there. Usually, anyway. Today he's been mostly occupied elsewhere, making sure some kind of equipment was working somewhere else or. Whatever. Not important. What is important is this new dude he comes across coming out of the R&D area, and like the friendly neighborhood Spider-Man that he so is, he stops to check on him.

"Oh, hey! I haven't seen you befo-OH MY GOD."

That would be Peter glancing past this new buddy into the R&D area and seeing this great horror-fungus all over the goddamn place. Oh no. Oh dang. Ooooh no.

"What is this!? Literally all my stuff is in there! Like, all of it! What the Hell!? I-- nggghhh!!"

I mean he's going in there for his stuff. He's getting ready to crawl across the freaking ceiling if he has to this is bullshit he hates this.
