Bruce Banner. Tony Stark. The teenage years. Yep, Peter was in the Twilight Zone. Regardless, he gave a small wave and a smile to them, even if now wasn't a good time. Neither was it a good time for him to say, "It's an honor to meet the both of you." Which he said anyway, because really, it was. They were part of that Avengers team, both were geniuses and he admired each of them more for their advancements in robotics and science than their hero work.
"Wait...so you're saying that we need to go and...get one of those things," Peter motioned to the screen, "And then...bring it back here, hopefully with enough time to convert it?" It was hard to tell if this idea was terrifying or exciting to him. Yes, he wanted to drive a mech, it sounded freaking awesome okay? What teenage boy didn't want to go running around in a giant robot suit? Not many.
The problem was, how were they going to get it? Of the people there, Peter suspected the job would fall on him. It was okay for a teenage Stark and Banner to know what he could do because he'd likely never see them again. But Gwen? That was...problematic.
