Shade One: Slytherin!Sirius

"So... you're my new potions partner?" the dark haired wizard said, looking slightly unimpressed.

Remus nodded his head, shooting a look towards a very angry looking James, who was seated next to Snape, though they were both at the edge of their seats, trying to put as much distance between them as possible.

"You're not good at potions," Sirius said, bluntly.

"Yeah, sorry about that," Remus began. "I've been trying to get better, but I just can't seem to do anything that involves measurements. I'm just as bad at cooking. My mum won't even let me make toast," Remus babbled, nervously.

Black's expression shifted to amusement. "Do you always talk this much?"

Remus shook his head again, trying to control his verbal filter.

"Right. Well, you're not just going to sit there and do nothing. You get the ingrediants, prepare, and read out instructions and I'll make the potion," Sirius ordered, already turning away from him.

Remus was relieved, feeling it was a good comprimise. Maybe he wouldn't fail potions after all!

...oOo...

Remus looked at the mark on the Assignment he had handed in along with a potion. He had done the majority of the writing, to make up for his dismal skills, and he looked at the O on the work.

His first ever O in Potions.

Sirius was still packing everything up as Remus walked back to the desk. The room was emptying quickly. He looked up as Remus rushed over, unthinkingly throwing his arms around Sirius tightly.

"An 'O'," he said. "This is the highest grade I've ever received in potions!"

Sirius stood stiffly, and Remus blushed, beginning to move away, until arms moved up around him, loosely wrapping around his back.

"I... yeah," Sirius said, confusion in his voice. "That's... great."

Remus let go and stepped back out of his grip and Sirius felt the need to pull him back.

He didn't know people who liked to hug. Even his own parents didn't like hugging.

He liked it, and Remus smelt wonderful.

But before he could open his mouth and say something, Remus had shot him a smile and left the room, leaving Sirius staring after him.

...oOo...

"Are you sure he's not following you?" James asked, his eyes narrowed at the Slytherin who was sitting at the next table in the library.

"Of course he isn't," Remus said firmly. "Sirius gets good grades, he must study a lot."

"Then why haven't I seen him in here before?"

"Maybe for the same reason he hasn't seen you in here?" Sirius muttered from the next table, causing Remus to grin.

"What are you smiling about?" James asked.

"Nothing," Remus said. "Why don't we meet in the common room later?"

"I don't know, I don't trust him," James muttered.

"Fine. Let's go for a walk?" Remus said, slamming the book shut.

James turned his head when he reached the door, to see Sirius putting his own books away quickly.

...oOo...

"He's stalking you," James said. "He's been doing it for weeks now."

"He's not that bad...okay, I get your point now," Remus said, as they spotted Sirius leaning against a wall, a cigarette between his lips.

"Hey," Sirius said, his eyes widening. He quickly dropped the cigarette, stubbing it out with his boot. He looked at Remus guiltily.

"Not going to take house-points, right?" he asked.

"No," Remus replied, with a smile. "I saw nothing."

"Great." Sirius flicked his wand at the half a cigarette, making it disappear. "So..." he glanced at James, who was glaring at him. "Uh, so... I was going to suggest that you get extra help with your potions."

"What?" James asked. "What does it matter to you?"

"I work with him in potions," Sirius replied, the hint of softness leaving his voice as he addressed James. "And Lupin clearly isn't that good at the practical side. He could use help, and I'm one of the best in the year at the subject. I was just offering him help."

"At what price?"

"Price?" Sirius asked, a smirk appearing. "Is that what you think? That I only do things for people because I want something in return."

"Pretty much," James offered.

Sirius pushed away from the wall, a cold look on his face. "I only expect Lupin to start pulling his weight," Sirius stated. "I thought if I helped him, there wouldn't be so much left for me to do during the lessons."

He turned and walked away and Remus sighed. "It's true, I should start pulling my weight a bit more," he said.

Things around Black were cold after that. Where they had maintained a level of friendliness before, that seemed to have disappeared... though the constant presence of Black nearby baffled him.

It was like Sirius was following him, but he couldn't be sure, because Sirius didn't seem to like him. He barely looked at him and only spoke to him regarding the potion they were making.

The friendship that he had thought was forming had quickly disappeared.

...oOo...

Remus stumbled through the castle. He had left the dorm to find something to eat whilst he recovered from the full moon, but his legs were shaking and his vision was blurring.

He looked down the stairs that he needed to go down. Just one more set.

His gaze on his feet, he carefully took one step, and than another step. He made it halfway before his body gave up, and darkness took him as he felt himself begin to fall.

...oOo...

This was not his room, was Remus' first thought as he opened his eyes. The smell was all wrong. His room smelt like James' unwashed Quidditch kit (because that's what was left laying around).

This room smelt clean, with a lingering scent of aftershave. He looked around, meeting stormy grey eyes.

Sirius stood up from the chair and walked over. He placed his hands on the bed and leaned down, his face close to Remus'.

His gaze flicked down to the bed.

"So... mind if I Slytherin?"

Remus wasn't sure if it was because he had just woken up, but Sirius' words didn't make any sense.

"What?"

"Slytherin - Slither in. Get it?" Sirius sighed. "It's not so clever if I have to explain it." He took in Remus' confused expression. "Can I join you under the quilt?"

"Oh... well it's your bed... isn't it?" Remus glanced around, blushing at the pictures of half naked men on the walls, posing for him.

Sirius followed his gaze and smirked.

"Do you want it to be mine?" he murmured, his lips close to Remus' ear, causing Remus to shiver. He pulled back the quilt, slipping under.

Remus briefly wondered if he was dreaming. Surely he couldn't be sharing a bed with Sirius Black?

"Well, it would be a bit weird if you put me in one of your room-mates beds." Remus' gaze moved around the room, before snapping to Sirius.

"You have your own room?"

"I do," Sirius whispered, his gaze falling on Remus' lips. "All the privacy I want!"

Remus realised that Sirius was shifting closer to him and hurriedly began to get up, wincing in pain. He froze as fingers gently wrapped around his wrist. "Are you leaving?"

He turned to look at Sirius, the tone of Sirius' voice almost sounded vulnerable.

"I don't know why you brought me here," Remus replied, trying to shift into a more comfortable position without showing how much pain he was in.

"I brought you here because you collapsed on the stairs near the kitchen," Sirius replied.

"So, no ulterior motive?"

"Well, not at first," Sirius stated. His eyes moved down Remus' body. "But you look so perfect laying in my bed, that I couldn't resist."

"Okay, thanks," Remus said, slipping from the bed. Sirius followed.

"Look, don't leave," he said. "I just wanted to spend time with you."

"You're the one who has been ignoring me," Remus replied. "What's stopped you from hanging out after class or something?"

Sirius' eyes dropped. "Your friend was pretty pissed at me, told me to stay away from you," Sirius replied.

"So you brought me to your room?"

"I only wanted to look after you and make sure you were fine after the full-moon. You were heading to the kitchens, I'm guessing, so clearly your friends weren't making sure you had what you needed," Sirius replied, defensively.

Remus turned around, meeting Sirius' gaze. "What did you say?" he whispered.

"I said that I wanted to look after you," Sirius replied, cocking his head. "Is that so wrong?"

"No, that's... that's not what I was asking," Remus said, Sirius' words reeling in his head. "You mentioned the full-moon."

Sirius nodded, and Remus slowly approached the bed, eyes narrowed, and sat down facing Sirius.

"What makes you think -"

"Remus, I know what you are," Sirius replied, not a hint of a smile on his face. "I know you're a Werewolf."

"And... if I was, what..." he trailed off.

"What were you about to ask?" Sirius demanded. "What would I want for my silence? What would I do with the information?"

His voice was cold now, the vulnerable look long gone and a mask replacing it, but he couldn't hide the hurt shining in his eyes.

Remus dragged his gaze away from Sirius'.

"No," he whispered. "What gave me away?"

"I watch you," Sirius said, keeping his answer simple, the mask fading slightly. "Sometimes I look over from the Slytherin table at you, and you look tired. Sometimes you're not even at meals. It doesn't take a genius to work it out."

"Is that why you stopped talking to me?"

"I already told you, it was Potter that told me to stay away. He said I wasn't good enough for you. Said that you could do better than a Slytherin."

"What -"

"Lupin - Remus, I..." he took a deep breath and his gaze moved to the bedspread. "Look, I'm Sirius Black. I spend my days with gorgeous guys basically throwing themselves at me. I have the money to do whatever I want, and I'm not short of admirers. I practically rule Slytherin..."

"Is that supposed to impress me?" Remus replied, snorting.

"Exactly!" Sirius exclaimed, jumping up. "It doesn't. You don't care who I am, or who my family are. You don't care about how much money I have. You're not trying to shag me because I'm the heir of the 'most important house'." He rolled his eyes at his last words. "You were nice to me because you're a nice person. You spoke kindly to me because that's who you are."

"Thank you?"

"I like that money and a name don't matter to you," Sirius said, his voice softer as he took a seat next to Remus again, making sure there was no space between them this time. "That's why I've been trying to get to know you, because it was nice that someone wanted to be my friend without a hidden agenda."

"I did want to be your friend," Remus admitted. "But then you were cold and -"

"I didn't want to upset your friends, they're important to you, and you're so loyal to them in return," Sirius murmured. "It's one of the things I love about you."

"Uh, love?" Remus whispered.

"Yeah," Sirius said, a small smile on his lips. "Look, it's not easy for me to say all this, but I'm mad about you. I can't stop thinking about you, and I keep wanting to follow you around to make sure no-one is trying to hex you or saying anything bad about you, like Snape keeps trying to do."

"I rarely get hexed," Remus said, trying to process the information.

"I just... I couldn't stay away," Sirius whispered, reaching for Remus' hand, before pulling his back, frowning slightly.

"Even though I'm..."

"I don't mind," Sirius quickly stated. "It means I can look after you every month. I'm good at things like healing spells and checking for injuries. I know you like chocolate. I can wrap you up in here and feed you chocolate and make you feel better?"

"Because you're a Slytherin?" Remus guessed, completely thrown by Sirius Black, sex god of Slytherin wanting to look after him, wanting to heal him!. The Slytherins were quite hex-happy at times.

He didn't miss the way Sirius' eyes shot to a photograph of himself with his brother and parents. "One of the reasons I'm good at healing," he mumbled, avoiding the question.

And having seen the Blacks around the Ministry and Diagon Alley, and seeing how cold they were, Remus completely understood.

Remus reached out and took Sirius' own hand in his, watching Sirius' face light up in a way he had never seen before.

It was mesmerising.

"Look, I might have come on a bit strong, but I've felt like this since that day when you hugged me," Sirius admitted, his gaze moving to their joined hands, a look of longing crossing his features. "And for you to be in my bed... even if you're just sleeping, it was perfect. I'm scared of scaring you off, so please don't leave. Being around you makes me happy."

Remus realised he was seeing behind the cool and aloof mask that Sirius wore, to the uncertain teen underneath. To a whole other person. He might be one of the very few people who had the pleasure of seeing who Sirius Black really was.

"But your family won't allow you to date a Werewolf, or a half-blood... you could do so much better!"

"Screw them," Sirius replied fiercely, his eyes flashing at the mention of his family. "Isn't having somebody to love the most important thing? I forced the hat to put my in Slytherin for them because I knew that I'd be punished if I went somewhere else. I just want the sort of friends you have - loyal ones. I want to laugh and joke like you do with them. I want to be close to you, like they get to be. I want to be closer to you than they get to be." His eyes darted to Remus' lips, and his tongue darted out, licking his own. "As for doing better - you are so beautiful."

"I'm the nerdy guy in Gryffindor that people tend to overlook," Remus replied.

"Well," Sirius said, moving closer again, his eyes darting down to Remus' lips again. "Brainy's the new sexy."

Remus held his breath, wondering - hoping - that Sirius was going to kiss him.

"If you need to think about it, I'll give you time, but I would love to take you to Hogsmeade on a date. If you say no, if you don't feel anything..." Remus could see the worry in Sirius' eyes. "You can go and I won't give up your secret. I promise. If you're not interested, I'll leave you alone."

Taking a shaky breath, Remus leaned in closer to Sirius, watching the grey eyes widen in hope. "I'll leave when I want to," he began, "but I don't think that'll be just yet."

"Where do we go from here?" Sirius whispered, uncertainly.

"Well, maybe it would be a good idea to see if there is any chemistry between us first?" Remus said, blushing deeply and struggling to meet Sirius' gaze.

"If you insist," Sirius murmured, his free hand moving to Remus' cheek, and his fingers stroking down it until they reached Remus' chin. He gently pulled Remus' chin up towards his face.

Remus' breath was shaky, and he could feel Sirius' warm breath against his own lips as the distance was slowly closed between them, silver eyes meeting his until the last second.

Remus' amber eyes fluttered closed as the gentle touch of Sirius' lips against his own and his heart was pounding once more. His hands reached up as the lips softly moved against his, one winding around Sirius, the other one on the back of his neck. He was sure Sirius would be able to hear his heartbeat.

Sirius pulled away too soon, and looked at Remus expectantly.

"So, lots of chemistry," Remus replied.

"So... will you give me a chance?" Sirius asked, hopefully.

Remus nodded his head. "Maybe now is a good time to admit I've had a crush on your for a while... I've been thinking about you all Summer, and since we've been back."

Sirius grinned. "Do your friends know?"

Remus nodded slightly. "I think they suspect. Maybe that's why James warned you away? He'd assume that you'd try to take advantage of my feelings for you."

"I would never," Sirius promised, taking Remus' hand in his own, and meeting Remus' eyes. "I'm completely yours, and I could never hurt you. I promise you that."
