During The Half Blood Prince. I was sorry for noone coming to the Room of Requirement any longer, and I thought Luna might feel the same. And who would she find if she spent her time at the place she loved?

"Hello, Draco."

Draco Malfoy spun around, eyes wide.

"What are you doing here? How did you get in here?"

Luna Lovegood, he knew her well. He knew all his enemies well.

She gave him a puzzled look.

"Same as you, of course. Three times pass, and wish sincerely, and the Room of of Requirement opens. You must know that, you are here, after all."

Draco's heart was still racing. There she stood, in her Ravenclaw colored school robe, with her long blond hair and that innocent expression on her face. So Potter was finally making an effort spying on him.

He considered his options. Attack her?

But there was a wand in her hand, casually pointing to the floor, but it was there. She was probably crazy. But she was a Ravenclaw. She wasn't stupid.

Unfortunately, she was also friends with his mortal enemy, and from all he knew, very well trained in attack and defense spells.

So, he should first try to talk himself out of this.

Damn. If he couldn't silence her, she could ruin it all!

"Of course I know how I got in here!" he snapped. "But how could you come in here after me? That's not possible!"

Luna smiled. "You sound like the door of our commonroom. But that's not really a difficult problem. That's something a first year could solve."

"What?"

With mindboggling patience, she explained it to him. "If we assume I haven't been able to come in after you, then I must have come...?"

"Before me? But then how could I come in?"

"I didn't close the room off behind me. It seemed a bit selfish to me to cut everyone else off this wonderful place when they might need it. Of course, I wasn't really busy in here like you, Draco. I just wander around. This is such an interesting room. I must have found the most amazing colony of nargles somewhere in here, which is quite an unusual habitat for them."

Draco told himself not to let himself be distracted by her chatter.

Why did she smile at him all the time? Why wasn't she afraid?

Of course, she had brought reinforcements with her.

"I have Crabbe and Goyle nearby," he said. "I can call them in any second."

"Oh, really?" smiled Luna. "So they are the girls you surround you with? I had been wondering about it. Polyjuice potion, I suppose. I shouldn't be surprised. I heard you're very good at potions, Draco."

"Thanks," growled Draco. Her voice was clear like an angel's. How could she stand there and compliment him and smile at him like this? What was she planning?

"Who did you bring and what are you buying them time for?" he asked directly. The subtle approach hadn't brought him very far with her.

Luna was perplexed.

"What are you talking about, Draco?" she said. Draco. Not Malfoy. She must be playing with him. A beautiful, pureblooded powerful witch had him at her mercy, playing with him, smiling at him. Through all the humiliation and danger, Draco couldn't deny the magnificience it had.

"You're spying on me," he stated.

"Yes."

"Do you have to smile all the time, damnit?"

"Smiling is an expression of good will and happiness," said Luna. "It's supposed to put the other at ease."

"At ease?" snapped Draco. "I'm supposed to be at ease when you hand me over to Potter?"

Now her face was earnest, for a moment. At least that was something.

"Do you think that's what I'm going to do?" she said. "What sense would it make to stand here and talk to you, when I could have cast a petrificus totalus into your back instead, if my intentions were hostile? What logic is that? You must have slept through all your arithmancy classes."

He had to admit she had a point here.

"But then what do you want?" he asked.

"I want to find out what it is you're doing here."

Wow. Twenty points for Ravenclaw for clarity, thought Draco sarcastically.

"And did you?" he asked, forcing himself to sound calm while panic ate a big hole into his stomach.

If she had, he was done for. Azkaban, or death through the Dark Lord's hands. If he was lucky.

"No. But it's very intriguing."

That smile again. Please, not that smile again.

"Listen, Lovegood... it's noone's business what I'm doing here. This room is for everyone in Hogwarts. Noone needs to spy at me and be intrigued. Leave me alone, have you got that? And if you tell anyone you've seen me in here... then... then I'm afraid you're not going to leave this room ever again."

"I'd have left in the first place, or why else would I be able to talk to someone?" she corrected him.

That was enough. She was right. He couldn't let her get away. If she left this room, everything was over.

Faster than ever before in his life, he flung his wand out.

He fell like a tree.

He had been right.

She was prepared, and she was really good.

While he had been careless, and deserved this.

At least he'd die figthting.
