"So you are asking me to pity you...?" Severus slowly walked back around the desk, his head was already going through the ingredients, wondering how much he had in his supplies, but his face stayed blank. "You should know, Lupin, that guilt tripping me is not going to get you anything from me..."
He sat down on his chair, relaxing towards the back of it, he looked ghostly, his feminine face pale, in stark contrast with his black clothes and hair. "And money, Lupin Lupin... if I had ambitions for money, I would have never accepted to come back to Hogwarts, now, would I? I would have asked the dark lord for something different... or you've forgotten what kind of person I am, Lupin?" he snarled, and sighed.
"I suggest you come back when you'll have something to offer me." he said simply then, his voice sort of bored.
