Rodolphus goes pale at the mention of the Dementors. Somethings, even he finds disconcerting. "What I wouldn't have given for some of that!" he manages to say.
"Thank you Lucius," he eyes the plate hungrily. "Oh," he says, disappointed. "Tea then, I guess, if it's not any trouble." He makes up his mind to find a pub as soon as he can conveniently get away. He picks up a sandwich and bites into it with relish. "You say that like it's a bad thing," He tells Severus after disposing of a huge bite. "What's wrong with thinking a potions master should be able to brew good beer? If anything, I should think you'd find beer-brewing a welcome change. It's certainly less complicated than the potions I remember having to do." He takes another bite.
