In Grimmauld Place 12, under one of the bed lives a Bogart. It was Sirius favourite thing to scare Regulus with when they were younger, he used it for years. It didn't matter how many times Sirius set it free in Regulus room, the Bogart always scared him. Regulus was the favourite victim when it came to pranks and horror stories, not just because he was the youngest but also because he had a so vivid imagination that you only had to tell a little bit and he thought up the rest himself.
So came the summer after Sirius first year of Hogwarts. This time when Sirius went to get it, instead of becoming some of the things Sirius usually was afraid of (Zombies, people who are missing their heads or dandruffs) it became a perfect copy of himself. Cold grey eyes was looking right at him, just looking.
Sirius felt like the temperature in the room had dropped and he couldn't stop the shiver that ran along his spine. The other Sirius noticed this and the smirk on his lips went from barely there to a smirk that could rival the ones he was used to see on his mother when she was able to make him upset or sad. Shifting on his feet, Sirius looked down at the floor and the up again. The other was still there. It wasn't until now he started to notice the different between him and the other Sirius. On the school uniform Sirius couldn't wait to change come Fridays, a Slytherin badge was located were his Gryffindor badge used to be. Green, silver and a snake had replaced red, gold and a lion. He couldn't stop starring at it.
The other Sirius looked down at it too and laughed, a laugh so much like his fathers that he almost jumped and had to take a quick look around to make sure his father wasn't in the room. Looking back at other he saw the other flicking back some hair that had gotten in the way when the other looked down at the badge.
Finally out of his trance Sirius took a step back while the other took one forward until he felt his back hit the wall. Standing just two feet a way from him, the other smirked before uttering twelve small words. Even though the words are whispered, in Sirius head he could hear them being screamed until he thought his head would explode. Forgetting everything he ever heard of Bogarts, he started to searching for a way to escape. Fumbling with his hand along the wall he found the handle to the door and pulled it open before running out. Running down the hall the words the Bogart had whispered echoed in his head.
