Slughorn's potions classroom was dimly lit. The sixth and seventh year Gryffindors and Slytherins crowded around the tables. The marauders - James Potter, Remus Lupin, Sirius Black and Peter Pettigrew - stood to the right side of the room and a group of Slytherins who deemed themselves the pantheon stood to the left side of the room - Barty Crouch Jr, Evan Rosier, Pandora Rosier, Dorcas Meadowes and Regulus Black. The scent of love filled the air.

Most of the boys had started snickering the moment Slughorn described the potion. The girls were giggling. "Amortentia is the most powerful love potion in the world." Said Professor Slughorn. The man strolled through the rows of desks, the cauldron sitting at the very front. "It does not create love, but, rather, shows you who you love the most. The scent changes for every person, you see, and causes powerful infatuation and obsession to the witch or wizard who stands by it long enough."

Even the boys had stopped snickering and groaning now. Besides you, Regulus Black shifted uncomfortably. To the other side of the room, his brother, Sirius, rolled his eyes as if this potion were beneath him. Typical.

Slughorn was opening the cauldron now. The scent of love was stronger, and the pink potion wafted through the air. "Now," said Professor Slughorn. "I want each and every one of you to focus on what you smell. You must be very careful, because I will only leave this cauldron open for a few more moments. Once you are certain of what you have smelt, I want you to write down the notes of the potion for your essay."

Everyone groaned again, not just the boys. Regulus stiffened, when realising that he would actually have to smell the potion now for his assingment. He had been plotting just to make it up. Regulus Black did not dwell on things like silly little love potions, but he leaned closer regardless, in favour of wanting to pass the class.

He knew what he smelt. Exactly what. A knowing look passed his face as if it confirmed some unsaid query he'd had for years. It was unmistakable, the scent of the potion. He wrote it down, and saw you watching him. "Have you smelt anything, then?" Said Regulus coolly.
