It had been late afternoon and Harrys hands already hurt from the plain and frustrating detention he had been asigned by Professor Snape. His aching hand slighty ink stained placed the feather he was writing with down beside the parchement. He started to move and stretch his hand a bit to get it to feel less tense.

The teacher had left him without supervision for a second, absentmindedly he brushed through the detention slips he had to rewrite to let his hands rest for a second.
Most of the names on it had he barely heard or cared for. The names Marlene or Dorcas slipping past him, why should he know those ancient people anyway. He just neatly rewrote what had been on them, well as neatly as his messy writing could be. He didn't seem much bothered as he copied

"Evan Rosier was found terrorising first years".

Neither did he get suspicious with all the Pandora or Mary slips he found.

He picked up some new detention slips to copy them as his eyes fell apon one especially interesting one. What ought to be ancient, barely readable pieces of parchment appeared to be not that old after all. The handwriting was making it a bit harder to read but with much doubt Harry figured out the scribbeled words. Trying to gaslight him into thinking he misread he reresd the words a few more times.

"James Potter and Regulus Black caught snogging in the quidditch changing room."

He halted, mouth dropping open. His dad? And... Black? Wasn't that Sirius' Brother.
His eyes blinked a few times very perplexed before he let the detention slip slide into his shirt pocket. He paused, trying to get the picture out of his head.

Gotta show that to Sirius and Remus. They ain't gotta believe what he found. He turned to look for his Professor, not seeing him anywhere he went to continue his work.

His elbow however had knocked over a pile of the written on parchement and he picked it up, frozen in a squatting position he stared at the unorderly spread cards eyes wide.

"Sirius Black had been dress coded for wearing a vulgar shirt displaying the words 'I fucked a werewolf and i liked it!'"

He grabs the pile of cards and picks it up, flinching as Professor Snape appeared behind him suddenly.

"Found something interesting, Mr Potter?"

Almost jumping out of his skin he tried to stay calm.
Shaking his head he proceeded to place the slips on the table and continued writing the last one with shaking hands.

The black haired man behind him grinned, it wasn't pure coincidence which box he had gotten. James son gotta know what chaotic and embarracing pile of teenagers his dads friend group had been.
After Harry had been left alone with his thoughts again he slipped the Sirius one also into his pocket.

He put away the freshly written one and got ready to copy another one. Setting his ink loaded feather on the parchment paper he started absentmindedly copying. It wasn't before long he actually realised what words had painted the surface.

"Drunk James Potter and Sirius Black dancing on the table to muggle music. Inappropriatly dressed."

He sighed heavy and put it aside, drumming his fingers against the wooden desk as he paused.
Jesus. His dad and friends definitely were chaos. Chaos he didn't want to imagine. His hand started to massge the bridge of his nose, pushing his glasses down a bit.

"Shocked? It must be quite frustrating to find out your parents are gay. My condolences, Mr. Potter"

Snape said behind him, expression mocking and very indiscreet enjoying the sight of seemingly traumatized Harry.
However completly perplex the Gryffindor just shook his head, not even acknowledging the twisted enjoyment the Head of Slytherin radiated with no shame.

"I know my god father, not surprised about their homoerotic tendencies, Sir."

The Professor huffed, obviously frustrated his plan to completly shock and derailing Harrys expression of his dad failed, and crossed his arms.

"Keep going or you'll do this all week."
He sat down opposite of him, a grudge on his face, and started grading potions work, not even paying any mind to Harry. His spite was definitelly gonna be noticeable in the grades that were going to be given.

The boy however was very much disturbed despite his already slightly present knowledle beforehand as he decided not to pick up on the words he writes down anymore for his own sake and just copy it as if it would be fantasy.
He brushed over all the mentions of dresscoding his godfather, of his Dad strutting and appearing to be everything but what he imagined, of Remus being just as down bad and many more he chose to ignore. At the end of the detention, with completly ink stained hands and face from rubbing his temple of bridge of the nose in discomfort he picked up his things and quietly left the room, leaving the teacher with a sickly content feeling back, grading more works.

As he reached the Gryffindor rooms, he fell down exhausted on his bed in his dorm room, staring at the ceiling.
Ron and Hermione had been told about all of the things he wrote and remembered, and even shown some of the stolen detention slips and were just as disdurbed, but even than instead of laying there like their friend, they found more enjoyment in nagging Harry about his families friendgroup.

"Almost sounds like Draco and you"
One of them teasingly mentioned, and got the expected rise out of Harry.

"Nothing about me and him is homoerotic!"
He exclaimed, huffed and just went into the common room to write a letter to Sirius and going to blame him for what he had to write due to him and his dad.
Ron and Hermione still giggeling as they thought about all the very homoerotic situations their best friend had been involved in, apparently without much acknowledgement.
