Sirius rubbed the back of his neck nervously as he trailed after Hermione towards the Black Family Library. His eyes dropped to take in her lightly swaying hips. He unconsciously tilted his head to the side, enjoying the nice view of her back side.

"So what are you looking for?" Hermione's voice broke him out of his trance.

His head snapped upright and he was thankful she hadn't turned around to ask him. "Oh, right. I'm looking for something on, uh, ancient runes."

"Really?" She stopped and turned towards him. "I didn't realize you were interested in ancient runes."

"Sure I am." He hoped she didn't ask him anything further about them, because he honestly didn't know anything about them.

"Do you need something translated?" she asked as she turned to continue on their way.

"Yes," he answered, the word drawn out strangely.

She chuckled softly. "Do you need any help?"

As much as he wanted her attention on him, he knew he couldn't ask for her help translating an imaginary document. "Err…I think I'd like to give it go myself first."

"I can respect that," she said. She opened the door to the library and froze.

Sirius jerked to an abrupt halt but still bumped her lightly. He looked over her shoulder into the quiet room, wondering what had caused such a reaction. Confused, he looked around for something more than Remus sitting in an armchair, but there was nothing else. He waited while the girl took a deep breath and entered the room.

"Hello, Hermione," Remus said, looking up, "Sirius."

"Hi Remus," she said in a low voice. She didn't even look in her ex-professor's direction; she disappeared down the rows of books.

Sirius glanced at a befuddled looking Remus and shrugged his shoulders. He had never seen Hermione so cold to his friend. What had happened between the two of them? She said they were looking guilty, maybe she didn't believe it was only a chat like he told her. Feeling even less certain of himself, he followed down the aisle she had vanished in.

Sirius took several turns before he located the pretty, young girl. She was diligently scanning the spines of the books lining the shelf in front of her. Once again, his plan backfired. Hermione pulled an enormous book off the shelf and handed it to him.

"There you are." She smiled at him.

"That was much quicker than I would've imagined."

"Yes, well." She blushed and looked away. "Let me know if you decide you want some help with that translation."

"Certainly," he mumbled, examining the tome. He watched out of the corner of his eye as she made her way out of the stacks. He started to trail behind her until he heard Remus's voice.

"Is everything alright, Hermione?" Remus asked.

"Sure." Her voice dipped low.

"You're angry with me?" He sounded surprised.

"No, not angry," she paused. "Look, Professor, could we talk about this tomorrow? I'm awfully tired."

"Of course," he whispered. When the door closed with a soft 'click' Remus sighed. "Professor? Why am I Professor aga-? Sirius!" He leapt to his feet and walked furiously towards Sirius where he hid behind the rows of books. "Sirius!"

"What Moony?" Sirius pretended to be absorbed in the volume in his hands. "Why are you shouting? This is a library, aren't you supposed to whisper?"

"What did you do?"

"I don't know what you're talking about." He took a step backwards as Remus was looming over him.

"She was fine until she went to check on you. And after half an hour in your presence, I'm suddenly Professor Lupin again. Do you have any idea how long it took to break them of that? Especially Hermione! Now what did you do?"

"Honestly, mate, I don't know. We were just talking and I asked her for help finding a book."

"Talking about what?"

"Why you and the boys were acting guilty after I left supper. I told her it was nothing."

Remus sighed and rubbed a hand across his forehead, which let Sirius breath easier. He only did that when he was calming himself down. "I'll have to talk to her later." He grabbed the book out of Sirius's hands. "What are you doing with this?"

"Translating something," Sirius answered vaguely.

Remus snorted and shoved the book back into his hands. "Glad to see you're taking Harry's concerns seriously."

"Remus," he began but his friend held a hand up in the air in front of him.

"Padfoot, I don't want to hear it. If you ruin your relationship with Harry, that's your business." Sirius opened his mouth to protest. "But," Remus continued loudly, "I'm not going to go down with you."

"Moon-"

"No." He turned and left a speechless Sirius.

"All this drama just to shag a pretty little thing." He flopped into a chair, fully aware it was no longer about sleeping with her.
