Panicking, he thought of anything to say. As long as it didn't sound stupid it would do. Oh come ON! What was there to say? Hello Lupin? Lupin, what are you doing here? How are you, Lupin? But decided to rest upon a simple:

"…Lupin?" forcing himself not to sound surprised.

"Good evening, Severus. Am I disturbing you?" Lupin smiled sincerely.

"…Of course not." Snape muttered, trying to sound sarcastic. Lupin flicked a few light brown strands of hair out of his equally brown eyes. Amber, actually. Snape quickly surveyed him. He was still very thin, as he remembered him. His cloak was quite loose on him, and his light brown hair, was scattered with gray, and many shades of brown. He still looked just as calm and well mannered as he had remembered him.

The click of the dungeon door shutting broke the silence.

"I haven't seen you for some time." Lupin added cheerfully, turning round to face Snape at his desk. Snape looked as though he were going to say something, but then stopped abruptly and remained silent.

"I've come to ask of a favor from you, which I'm sure you've spoken to Albus about already." Lupin slowly approached the desk. Snape became more nervous at his every step.

"Favor?" Snape snapped.

"The Wolvsbane." Lupin said. One would have though that he wouldn't be too keen on the subject, but being Lupin, he said it casually like he said everything else.

"Yes, I have spoken to the headmaster about it." Severus said, trying to look distracted --suddenly very interested in Henry Harleton's potions homework.

"Excellent. I hope it isn't too much trouble."

Snape rolled his eyes. Why did Lupin have to be so damn polite?

"No trouble at all."

Snape suddenly had a very strange vision. He had a collar round his neck, and his name written on the front in shiny golden letters. The collar was attached to a chain that was attached to his dungeon wall. And Lupin was there, petting his head and scratching his ears, and telling him that it was his turn to be a werewolf.

Snape raised his eyebrows, at that thought, but then remembered Lupin was there and looked up. He had been so lost in thought that he hadn't even realized that Lupin was standing right in front of him by the desk. He felt his face burning red, and immediately looked back down at his papers, trying to hide in a strip of shade from his window.

His eyes wandered back over to Lupin who had the strangest look on his face. He couldn't distinguish it. It had to be a mix of curiosity, annoyance, grief… it was the look someone would give when they were in very deep thought. Snape watched him closely.

"Is there something else you wish to tell me, Lupin?" Snape muttered, hiding his face back in his papers. He made it sound like he was thinking of any excuse to make Lupin leave. Actually, he was. From the corner of his eye, he saw Lupin look back at him.

"Uhh..."

"Well, why are you still here then?" Snape suddenly blurted, growing redder and redder. Lupin took a step back. He looked up, over Snape's shoulder towards his clock.

"Oh, right! Look at the time! I best ought to go," said Lupin quickly.

"Good evening." He spun around, opened the dungeon door, and left Snape feeling as alone as he was before. It has a horrible feeling, considering that fact that the man he'd been thinking about for weeks had just left his office, and was sent to leave by him.

Miserable, Snape but his chin back on his elbow and continued the potions work.
