Re: Severus, Caitlyn
He closed his potion's book now that the ink from his notes was dry and slid it into his bag. The sight of it made him consider, carefully.
"Actually, no. There is one thing. I need a new Arithmancy book. I wasn't able to purchase mine this year. Find one for me, and I'll teach you." Perhaps he'd start off with the spell that liquefied the bones in a person's body where you aimed it. He had high hopes for that one. The rats he'd been trying it on seemed quite affected. Not to mention the text subject Mulciber had supplied him with last Spring. He'd been angry then, and more than willing to take it out on someone.
