Q blinks at that. He can't even begin to imagine...well, yes, he can. And he'd rather not, thank you. He has enough nightmares. He gives a disapproving sniff. "So, more dangerous in the end. You never have to worry about that with trolls. You always know where you stand with trolls."
"The needs of the many outweigh the needs of the few," he says quietly. "Or the one. My sanity would have been a small price to pay."
Q tries to return the smile. "Herpetology has never been of much interest to me." He manages to suppress a shudder. "But I'll take you at your word where snakes are concerned." He doesn't even like to think about them. "You managed," Q says pointedly.
Q nods. He'll take Severus' word for that too. "She must have been younger than Ron then," he murmurs. He counts on his fingers and his eyes widen. "Of course. And do you know how I might get in touch with said Miss Weasley?"
