Chapter 1
Peter had been taken by the 'meme-hoes'. As MJ and Shuri called themselves. T'Challa just deeply inhaled whenever they shouted the name, as if he didn't even have enough energy to say anything about it. Tony only took him from the two girls constant vine and emo band references when Peter came up in Avengers related conversation. No shame in letting him hang out with his friends.
And okay, maybe their references weren't the worst. Confusing? Yes. Out of nowhere? Definitely. But mostly they pulled harmless pranks or messed around with inventions. Nobody knew how the fuck Peter had already made his webshooters a thousand times better in the three days they'd been there. In fact, they'd done a lot of tech-stuff since the Avengers arrived. MJ usually just sat back and watched to make sure nothing exploded. And also somehow allied herself with Natasha. Which was threatening.
One time Peter passed Steve his shield by yelling, "This bitch empty, YEET," which both confused everyone and also was somehow hilarious to watch. Mostly due to Steve's face. Shuri did it with Bucky's arm too. (GIVE ME BACK MY ARM, YOU LITTLE SHITS) And everyone figured that those were the only things that reference could apply to. They were, however, extremely wrong.
Because as they were discussing the upcoming superhero shit, Tony wasn't paying too much attention to some of it, they heard the phrase, followed almost immediately by "Guys, I need that!" from Peter. They were all expecting some sort of mechanical object, perhaps a webshooter. Not most of his fucking arm.
And then, besides Tony, who was sitting with an 'oh shit' face, they did what any rational person would do when your teammates dismembered arm was sitting on the table, somehow not bloody.
They screamed.
