Aha, chapter two of my fanfic. This is based off prompt Two (surprising, no?). Includes a bunch of pairings that really aren't relevant to the rest of the story. Yay Avengers!
Two: Write a chapter that takes place in a cafeteria.

"And now I have detention after school!" Peter finished.
His audience – including Pepper Potts, Peggy Carter, Clint Barton and Tony Stark- swapped looks around the cafeteria table they were all currently seated at.
Pepper gave him a sympathetic look. "I'm sure it'll be fine.
Tony took a bite of his burger. "I never turn up to those."
"What, detention?" Clint asked from besides Peter.
Tony nodded. "It's not important."
Peter gave him a sceptical look. "Weren't you expelled last week?"
Tony grinned back. "I was." He shrugged. "Then dad bought the school a new building."
"Ah, so you're the reason my art class was filled with the sound of drills and workmen." Bucky said as he and Steve approached the table, sliding into place at the table.
Tony gave him a look. "You don't even like art. You're only doing it cos your boyfriend is."
Bucky wrapped a supportive arm around Steve. "He's cute when he's drawing."
Tony nodded, then added, "Peter's got detention."
Steve choked on his drink. "What?"
Bucky patted him on the back. When Steve finally got his breath back he exclaimed again, "What?"
Peter looked down and ran a hand through his hair. "I didn't…I mean…" He took a deep breath. "It wasn't…I didn't…" He sighed. "It was Wade."
Steve frowned and somehow Peter felt even worse. "Pe-ter."
Peter pulled his hair again. "It wasn't…I wasn't…He passed me a note," he began. "And I wrote back to tell him not to and it went on and then the teacher found out and now I have detention this afternoon."
He quickly peeked at Steve, who was still giving him a disapproving look.
Bucky caught his eye. "Want me to tell him off?"
Peter blushed and looked down at his food. "No, it's okay," he said. That was all he needed, Bucky scaring off his classmates. Even if it was Wade. Then his head darted up again. "I mean… not okay, but… yeah."
Bucky shrugged and bit into his apple.
Peggy tapped her pen against her notepad. "One time isn't that bad."
"Except it's on your permanent record now." Tony chimed in.
Peter paled. "That's a thing?"
Steve shot Tony a look. "He's kidding."
"No, he's not." Clint said. "But don't worry. Nat and I will sneak in and change it."
Peter elbowed him in the side. "Great, and you two can get caught and my record can go from a one-time offence to a criminal record."
"Nat and I never get caught." Clint said confidently.
Steve gave him a look. "Exactly how many times have you broken into- No, wait. I don't want to know."
The group laughed.
"Speaking of our only straight couple," Tony said, looking around to catch a glimpse of Nat's red hair, or Sam's cocky grin. "Where is the lovely pair?"
"Na's practising for the recital." Clint informed him. "And Sam's being the supportive boyfriend."
"Ah, yes, the dancing."
"The dancing," Clint confirmed.
"Speaking of dancing," Pepper interrupted. "The school dance is next week."
"The school dance." Tony closed his eyes and leant back on his chair. "Glad I came back just in time."
Bucky reached over to rest his hand on top of Steve's and grinned at Tony. "Can't wait."
Steve flushed and looked at Pepper. "Did you need help setting up or anything?"
Pepper, who was on the School Council, shook her head. "No," she smiled at him. "People always want to volunteer for dances." She looked at Peter. "I could ask McCoy if he'd switch the detention for volunteering."
Peter shook his head. "No, it's fine."
Tony leant forward. "So Peter, you got a date yet?" He winked. "I've got a few friends, and you're the only single one here. I'd hate for you to be all lonely, clinging to us like always."
Peter flushed. "Uh, actually-"
"He's going with me," Peggy said simply.
The boys all looked at her in shock.
"What?" Clint said finally.
Tony looked between Peggy and Pepper. "Did you two break up?"
Pepper gave him a firm smile. "No." She looked back at her phone. "But I'll be busy running the dance, so I suggested they go together."
Tony raised an eyebrow. "Smooth move, Parker."
Clint slung an arm around Peter's neck. "Oh Peter, our neighbourhood bad boy."
Peter laughed, and Tony added, "Next thing you know he'll be climbing on the rooftops." He paused, waiting for people to get the joke. "Parkour," he said finally.
A groan went around the group, accompanied by rolling of eyes and shaking of heads.
"Glad you're back, Tony." Bucky told him.

A/N: Okay, so it was supposed to have TonyxRhodey and ClintxPhil, but I ended up not adding them in, so I suppose you could read it as TonyxClint instead. I don't know. And Sam is Sam Wilson, the Falcon.
And omg that Parkour joke, aren't I brilliant?!
