James is wearing Remus' jumper, with the hem falling past his hips and his fingers only just poking out of the sleeves, and Remus has been staring at him the whole time.

"I'm dying," Sirius says when James flaps his long sleeves cutely at Harry as they talk, walking ahead of Sirius and Remus down the hall to breakfast.

Remus makes a questionable noise. "I want you to wear my jumper too."

"It'd be too much, you'd snap and probably eat one of us," Sirius says gravely.

"I'd be worth it."

"Just," Sirius says. "Just - something, do something, this hurts."

"You do it," Remus hisses back. "And then when he says yes to you, I'll come in."

"Fucking coward."

"Why don't you do something then?" Remus complains.

Sirius throws up his hands. "When I kissed him last year, he thought it was a prank. The time before, he thought I wanted practice. What am I supposed to do?! How more obvious do I have to be for this dense motherfucker - Jamie! Yeah, what is it?"

Sirius jogs up to where James and Harry are crouched beside an entryway to an outside courtyard, waving Sirius and Remus over.

"I found a ladybug!" James cheers, fingers clutching at the ends of his long sleeves.

"Simp," Remus mutters, then walks over as well to go say hello to the ladybug James has now declared his other, other, other best friend.

"Aww, it's making a little rowing motion with its tiny little legs," James coos. He perks up even further at the idea. "Hey, you know what we should do today?"

"Row!" James yells, sitting at the end of the rowboat, hauling back on the oars as Remus and Sirius do, lined up behind him. They lurch forward again to reset. "Row!"

Harry walks down the busy corridor alongside the rowboat and, really, the Marauders are actually going quite fast with the modified sticking charms on the ends of the oars to help them along.

Students stream around the rowboat on the way to class, snickering.

"Row!" James cries and the rowboat lurches forwards (technically backwards). There's quite a bit of resistance doing this on carpet.

"What are you doing about the stairs?" a Slytherin asks as he stands off to the side watching with his friends.

"Oh fuck," Sirius says.

"Row!" James roars. "Come on, lads! A bit of stairs won't stop the Hogwarts rowing team!"

McGonagall catches them before they reach the stairs anyway so it's a moot point. They try to run away but she walks slightly faster and outpaces their rowboat.

"If it wasn't carpet we would have gotten away with it," James says earnestly.

"Why didn't you just do it in water?" Lily deadpans.

"The Hogwarts rowing team must be prepared for every terrain."

Harry pipes up with a little, "You could make a slip and slide instead, with plastic sheets then water and soap. We did that for graduation in primary school."

The line wraps around the edge of the Black Lake as what seems like half the school has stripped down to just their bare pants and shirts -some less- and they're all going to have a hell of a time finding their pile of clothes again.

James is straight up just in his underwear, still dripping wet from his last run, and takes off at a sprint over the grass towards the long plastic tarp, diving headfirst down the soapy runway on his stomach before pushing up and onto his feet for the last half, somersaulting into the lake with a splash that hits the other students floating around.

He pops back with a flick of his hair to the cheering of the audience and throws up a peace sign with a grin. If you're going to do something, do it with style.

Remus, with shirt and trousers on because his scars are really quite distinctive, takes off next and flips his legs around at the last second when he dives, spinning like a top down the slide on his back before splashing in.

Harry, down to his trousers, takes a step forward as the next in line then pauses. "Headmaster."

Dumbledore walks up with a smile and twinkling blue eyes. "Excuse me, Mr Potter, would I be able to use my Headmaster privileges to cut in line?"

Harry gapes.

Sirius cracks up laughing and it ripples through the line as Dumbledore steps up and they realise he's going to take a turn.

"Yes!" James screams in delight, slapping the water. "Fuck yes, Dumbledore! Let's goooo!"

Dumbledore walks up, still fully dressed in a hat and long robe of blinding purple, and stands on the end of the slippery slide before pulling out his wand. "Accio Black Lake," he enunciates clearly and then takes off like a shot, standing perfectly straight as he gets launched off the end and gets air time.

The students lose their shit and fall over each other laughing. Remus has to help James float so James doesn't drown because he's cackling too hard to tread water.

Dumbledore pops back up out of the water and easily does a graceful breaststroke back to the shore.

"I fucking love this school," Sirius wheezes in hilarity, clinging to Harry's shoulders so he doesn't topple over.
