Peter should have known someone was coming up. Spidey Sense man. But then again, it wasn't anything dangerous, obviously, or a threat, so maybe it made sense that he was jerked out of surprise when he heard the voice approaching behind him. Jumping a bit, he turned in his seat and looked towards ... well himself.
He knew there were other Peter Parkers obviously. He'd seen himself in clones before, he'd seen other versions of himself numerous times, but this was uncanny in resemblance. The other version, the one he was currently staring at, was probably a bit younger, that much was somewhat clear, but otherwise it was definitely trippy.
Shaking his head, Peter eventually managed to step away from the table and looked at his contraption, then back to his doppleganger, back again, and then back once more, "I uh... you must be Peter Parker. One of the others ones--I'm well I'm also Peter Parker. We'll need to work on naming conventions..."
He trailed off before making his way towards his counter part, reaching up to lightly poke the other in the chin, "Huh..."
Finally he stepped away and gestured towards the table, "Yea, uh, sorry just a bit weird to see... anyway. Hi. Yea, I'm sure Tony could help but I'd rather... not. Not right now. Plus I'm sure I've got it handled."
