Peter jumps when Tony suddenly grabs his arm to look at the glass now in his hand. It hurts a lot and there is still a steady stream of curses running through his head. He bites down on his bottom lip as Tony lays down the law in that firm, no room to even think about arguing, tone of voice of his. All the fight Peter had in him over the situation drains out the bottom of his hiking boots once he sees the look in Mr Stark's eyes and he seems to visibly deflate.

"Y-yes sir, I'm sorry sir..." He mutters as he looks down at the ground. He can't really take the webshooter off at the moment though with Tony holding on to his wrist. However, Tony made this version of the webshooters so he probably knows how to get them off.

But there's another problem in that he only has one at the moment. The other he'd given to Buttercup to try and give her some semblance of defense while she trekked up the mountain.

He doesn't think that Buttercup will be the one in trouble for that decision, especially since it was Peter's idea but Mr Stark is mad right now and that might not stop him from yelling at the little girl too. His eyes flicker over to her for a second as he tries to figure out what he should do before internally wincing at what's about to come.

"Um... actually Mr Stark, I uh.. I kinda... uh... l-lost one of the webshooters..." He lies right through his teeth, not daring to look at Tony's face.
