You’re Regulus

The Marauders heard that the Slytherin Skittles were having a sleepover and wanted to prank all of them.

The Marauders were 4 boys, James, Sirius, Peter and Remus. They were pranksters, Sirius will fuck anything, James is simping for a girl called Lilly, Peter is a helper and a follower then Remus is a bookworm.

The Slytherin skittles were a group of Slytherin boys and girls who are best friends. Regulus, Regulus is stoic and cold and Sirius’ younger brother by two years, Barty, he’s always drunk or high, Evan, Barty’s boyfriend and the only one with common sense, Dorcas, the cool one and Pàndora, gentle, shy and curious.

They were having a sleepover that night.

Sirius, James, Peter and Remus snuck into Slytherin dorms easily undetected thanks to James’ invisibility cloak.

The Slytherin Skittles were in a circle playing the classic Muggle game, truth or dare.

Pandora was sitting next to her twin, Evan. Everyone was in Pyjamas and all seemed well, they were blissfully unaware that Regulus’ older brother and his friends were there, just invisible.

Barty, with a drunken Smile slurred out.

Barty: “Regulus, I dare you to cast your patronus, if you can do one.”

If he can do one? Of course he could, Regulus had always known since 3rd year, it was a panther. Regulus wasn’t meant to be able to do one yet, it was a sixth year spell, at least.

The Marauders didn’t expect Sirius’ little brother to be able to do one so this’ll be fun to teach, they were ready to prank them of course but had to wait for the perfect moment though.
