"Harry," he whispered urgently. "I might sound crazy, but … do you think Lupin is a werewolf?"
Harry blinked at him. "How d'you reckon?"
"I just realised he gets 'sick' on a monthly basis," said Ron meaningfully, "And only when there's a full moon. When I had detention in the Hospital Wing back in November when Lupin was out sick, supposedly, he wasn't there. Besides, his Boggart is…"
"…A full moon," Harry finished. "Well, you're right. I asked him about it last year and he said yes."
Ron stared at Harry's composed face. Then he closed his eyes. He should be used to Harry's breathtaking ignorance of wizard matters by know, but sometimes … it was too much.
"Harry," said Ron, very slowly. "Lupin. Is a werewolf."
"So?"
Merlin's pants, it was like talking to an idiot. "They bite people specifically to make more werewolves."
"Yeah, it's really messed up," said Harry in quiet indignation. "I don't know how people managed before the Wolfsbane potion. Did you know someone actually tried to banish the moon to stop his son from transforming? It didn't work, obviously, but still. You can really feel for the man."
Ron gaped open-mouthed as Harry went on talking about the various ludicrous treatments for lycanthropy wizards and witches concocted over the years. Obviously he had taken the time to look them all up, which wasn't something Harry did unless he was stewing over an idea. That meant…
"Harry, are you trying to find a werewolf cure?"
"Kind of. I mean, I wasn't really thinking about making something new," said Harry, scratching his head. "The werewolf curse cuts down a wizard's lifespan easily by a third and ruins their health. Like that's not enough, dicks like Snape treat them like they're nothing but rabid wolves no matter what the moon phase. It's just not right."
Ron said nothing, but inside he felt an immense sense of relief. Harry using four-letter words meant he felt very strongly about it, and Ron didn't fancy his best mate thinking he was a dick at the same level of Snape, who was Dick King, full stop. Anyway, Lupin was a very decent bloke, werewolf curse aside. Perhaps he overreacted.
