A/N: I actually wrote most of this before HBP came out, forgot about it, then found it on my computer and finished it. So, yeah... AU after fifth year where Remus Lupin has returned to be the Defense teacher, and Draco Malfoy hasn't taken the Dark Mark. Enjoy!

It was a quiet night inside Hogwarts castle. Even in Gryffindor tower were the inhabitants silent, having partied themselves to sleep following their win in the season's first Quidditch match. A win against Slytherin, of course. Outside the castle it was similarly quiet, with one exception. The Quidditch equipment shed, where two (somewhat drunk) young men had managed to run into each other in their quests for solitude and fresh air…

Furious, Harry took a step closer to Malfoy, his wand coming up between them. "You leave Sirius out of this, Malfoy!" he shouted back.

The blonde shoved Harry's arm away. "Why should I? You're not! All you do is sulk about, moping like the man died yesterday!"

"Well excuse me for mourning my godfather! At least he loved me! You can't say the same about you parents now can you?"

"You don't know the first thing about who my parents really are, Potter, so you leave them out of this!" The blonde glared at him, his face mere centimeters from Harry's.

Harry opened his mouth to retort, but Malfoy's own somehow got in his way. Harry's eyes widened as his gasp of surprise got lost between them. The Slytherin took advantage of his gasp to slide his tongue in between Harry's lips, pressing forward forcefully and demanding submission. With an annoyed growl, Harry brought his own tongue into the battle. No way was he going to let Malfoy beat him at anything. Not even this. Especially not this.

-------

Slowly, Harry floated back to consciousness. He had slept well, without nightmares for the first time in weeks. Months, really. Smiling contentedly to himself, he stretched.

Or rather, tried to stretch. Something was on top of him, hampering his movements. Harry froze. That wasn't right. And come to think of it, his bed had never felt so hard before…

Cautiously, Harry opened his eyes. He wasn't lying in bed, he was stark naked on the floor of the Quidditch equipment shed. With an equally naked Draco Malfoy half draped over him.

Closing his eyes, Harry groaned to himself and immediately regretted it as a splitting headache asserted itself. He had known he shouldn't have indulged in the firewhisky Seamus and Dean had snuck in, he had just known it. But everyone had been so happy after defeating Slytherin in the first Quidditch match of the year, and Harry had been too caught up in the elation not to go along.

And just look where it had gotten him, naked with one of his worst enemies. Mentally cursing himself, Harry reopened his eyes and shoved Malfoy off of him. The blonde woke instantly, indignant at the rough treatment. Then his eyes widened as he took in his surroundings, his current state of undress, and Harry's hurried dressing.

Not looking at the blonde, Harry said with deadly seriousness, "No one is to learn of this." He glanced up in time to see the Slytherin nod wordlessly, still looking like what had happened hadn't quite sunk in.

Not trusting himself to say anything else, Harry turned and left, intending to sneak back into Gryffindor tower for a long, hot shower and a change of clothes.

Pausing on his way to the staff table, Remus Lupin paused to say good morning to Harry, Ron and Hermione. Ron and Hermione were the same as ever, tired but happy to talk to him. Harry, on the other hand, seemed strained and distant, though he denied that anything was wrong. Frowning slightly, Remus focused his senses, enhanced by the upcoming full moon, on the young man in front of him. There was an odd, familiar scent about him, laden with guilt, but also much more, something Remus couldn't put his finger on. Resigning himself to the fact that Harry wasn't going to say anything more, Remus continued on to the staff table and his own breakfast. As he sat himself down, he abruptly remembered where he had last encountered that scent. Sirius had smelled just like that, a mere two days before the "incident" with Snape and the Shrieking Shack in their sixth year. Remus' heart ached at the thought of Sirius, but he resolutely pushed that back. He had to maintain an image of strength in public, for Harry's sake if nothing else.

During the meal Remus kept a concerned eye on Harry. He had become better at reading his unofficial godson in the past couple months, and saw what the others most likely missed. The young man seemed to be forcing himself to be part of the conversations, pretending to be alright while determinedly not looking across the Hall. Almost fearing what he would see, Remus looked to the other side the room, to be met with another unusual sight. At the Slytherin table, Draco Malfoy sat aloofly silent, ignoring all of his housemates' attempts to speak to him. As Remus watched, the blonde shot an unreadable glance across the Hall towards Harry. The werewolf thought he saw the young Slytherin's jaw clench, but at that distance he could not be certain, proximity of the full moon notwithstanding. He decided he must have been mistaken, for after that glance the Malfoy heir seemed to withdraw even further within himself.

His eyes narrowing, the professor thought back to before that catastrophe, rather than after as he usually did. Come to think of it, Snape had also been acting oddly then. Not quite as obviously as Malfoy was now, as Snape had never been anywhere near as popular and his avoidance of everyone was a common occurrence, but still…

A/N: And before anyone asks, no I'm not going to tell you if Draco or Harry won the fight for dominance. :P
