Clint and Peter being Vent Bros™:
they became Vent Bros cause one day Peter was sleeping at the tower and he had a nightmare and he was super scared so he webbed himself into a vent
Clint found him and explained that the vents also made him feel safe and that's why he started hanging out in them
from then on they called themselves vent bros
if Peter just needs space he can go up into the vent and Clint knows to let him be
but they also hang out up there and sometimes they play vent tag, where Peter has to try to find Clint, and Clint is very good at hiding and evading Peter cause he knows the vents so well
sometimes they also crawl around together spying on watching people down below
they've gotten some good blackmail material this way, but Peter is too nice to let Clint use it
if its prank day in Avengers Tower (they have a monthly prank day) its either Peter and Clint against the rest of the avengers or against each other, there's no in between
something about the vents makes it easier to be honest, and Peter ends up telling Clint how his role as spider man weighs on him and its harder than he lets on
Clint tells Peter the same is true for him, being a superhero is more stressful than people realize and its ok to feel that way
Clint has a little nest up in the vents with pillows and blankets and books and puzzles that he goes in when he needs to relax, and Peter builds a similar one right next to his (but with webs instead of blankets)
if Tony is his Irondad and Natasha is his spider momma, then Clint is Peter's hawk friend
Clint is just irresponsible enough for Peter to feel like he's with someone his age
Peter takes his laptop up in the vents and the vent bros watch netflix together
sometimes you can find them curled up in their nests with a laptop between them, laughing at The Office
