All of the original Avengers and Loki are holed up with no electricity, and get very bored. Really no time in actual canon, but events through Ragnarok will be mentioned.
I WAS BORED SO DON'T KILL ME FOR THE RANDOMNESS PLEASE
"So," asked Natasha. "Does anybody know how to play Never Have I Ever?"
"I don't have a habit of learning mortal games," snarked Loki.
"Welp, somebody's cranky today!" laughed Tony. "Oh wait… you're ALWAYS CRANKY."
"SHUT UP, MEWLING QUIM!"
"Brother, calm yourself," said Thor, attempting to keep his brother from killing Tony.
"Can we play or not?" asked Natasha impatiently.
"Sure. Just tell us the rules," said Steve.
"So, basically, you hold up ten fingers, then whoever goes first says, 'Never have I ever..' and then something that they've never done. Whoever has done that puts a finger down. The last person with fingers up wins."
"I already knew that."
"No one cares, arrow-man."
"Tony, shut up. You're just cranky because your phone died," interjected Bruce.
"Can I go first?" asked Loki.
"No. Cranky baby has to sit in time-out," said Tony.
"DO YOU WANT TO BE STAB-"
"Calm yourselves! Yes, you can go first. Jesus, anybody would think that you all were small children in need of a sitter," said Bruce.
"Never have I ever… kissed someone."
"WHAT THE HECK!" said Steve, angered. "NOW I HAVE TO PUT MY FINGER DOWN!"
"Wow. I'm honestly not surprised."
"Why'd you say 'Wow' then?"
"No reason."
"Look, just because I threw you off a building once doesn't mean that you have to be deliberately rude, Stark."
"I have to admit, that was a pretty good one. Everybody in the room put a finger down," said Natasha.
"Wow, even you? I'm surprised."
"LOKI!"
"Brother, I'm JOKING."
"Well, we'll go clockwise, which means that Thor is next," interrupted Natasha.
"Never have I ever… umm… wow, I'm not good at this… ummm… Never have I ever wielded an Infinity Stone."
"Seriously? I am your brother. You do not get to-"
"THOR!"
"Wait, when did you two use one?" asked Thor, gesturing at Bruce and Tony.
"Well, I, umm," began Bruce.
"We may or may not have messed with it a bit when trying to figure out what we could do. Then Ultron happened," said Tony bluntly.
"What is this 'Ultron'?"
"Oh yeah, you never found out. But you know when I went to Earth for a while? I was helping fight a metal man."
"Wow. Thor, are you really the god of thunder, or are you just the god of oversimplification? Ultron was an extremely powerful A.I.," sighed Tony. "Which I may or may not have used the Mind Stone to help create."
"Oh, an A.I. That makes sense, especially in terms of how it went wrong," said Loki, no longer confused.
"What in the name of my father's throne is an a-i?" asked Thor.
"Really, Thor? Even I know what an A.I. is. Artificial Intelligence. I guess Loki really is the smarter one," snorted Steve.
Clint, who had been very quiet during this whole exchange, looked up and sighed. "Does it count if you were controlled by an Infinity Stone?" he asked. Everyone looked at Loki, who was fiddling with the end of a dagger. "Well?"
Loki looked up. "I don't think so - oh. Um, I, uh-"
Thor laughed. "'Um,' says the god known for having a silver tongue." Everyone looked at Thor. "What? I was just trying to lighten the mood! It got really, really quiet in here!"
"I'm sorry," Loki blurted suddenly.
