"So," Q says, jotting a few more notes, "the true stone is more of an ideal than a real object. And if you find it or make it, what? You go to heaven? Clean slate and no harm done? Like a cosmic 'Get out of jail free' card?" He looks at Severus. "What happened to the stone Voldemort wanted?" he asks bluntly.
"Really?" Q seems surprised. "I've had books that I suddenly wanted to read or re-read, but never anything like that. Not what I'd call talking to me." He rubs his chin. "Well, I wasn't really looking for anything in particular. Just something that you'd like and that would help me learn potions. I reckon I was hoping I'd find some old text books." He nods at the Compound. "I reckon I did at that. Do you think there's anything in there we can use? It seemed terribly obscure." He's not the least abashed to admit he had a look at the book before he gave it to Severus. It'd be much more a shock if he hadn't.
