Peter is instantly impressed by anything that can eat through his webs, slowly or not. He'll focus on that later though, because now he's got himself an opening and he's sure as shit going to take it. He hops up to the highest point of whatever shield he's attached to and leaps off towards Gokudera, figuring he'll just land on him and pummel him into the ground.

Y'know like. Non-lethally. He doesn't want to kill the guy with his ridiculous spider-strength so he is really trying to pull his punches.
