Lex met Remus' eyes again. "If necessary, are you desperate enough to follow up on a lead I might give you if I can't collect the ingredients on my own or hide a few extra purchases within the order for the school?"
He leaned back in the chair. "If the answer is yes, Wolfsbane, strengthening potions and healing/soothing salves. Shirt." Lex said it calmly - shirt as in off. He motioned with his hand as well. The boy looked amazingly thin. Dangerously thin, for a predator. He wanted to make sure he wasn't just assuming. "Your parents will pay for the first two. And I'll probably want report on what you eat."
He tisked. "Wolfsbane or not, it'd probably be safer for everyone if you put a little weight on. Your body looks like it's eating itself to death. And when it's not, you're physically gnawing on flesh."
