Remus snorted softly. "Why do I completely believe you would?" he teased. Although, considering how certain people had never felt any compunction to limit their mischief-making in the past, he wouldn't hold his breath hoping no one ever came down to the dungeons to cause a little of what they believed to be harmless mayhem.
"Ravenclaw tower shouldn't count, since it's not inhabited, but slated for the students and, therefore, truly normal," he pointed out. "And I'm not sure if it's actually password protected or just simply known to be unavailable, since there isn't anyone in there now. I did say I could think of a few who would have spells up. And maybe it's changed in the last couple of months. But, for a long time it didn't seem like most people here were very concerned about security inside the castle, just keeping things out."
And, then, just like that, Remus was reminded how different the worlds were that they came from, despite both being in the magical one. "I will never say no to books, so if you expected objections to a library I'm afraid I'll have to be a terrible disappointment. And a potions room is going to be all on you. I'd be useless with one, given I can't brew to save my life." He bit his lip in thought for a moment, having no clue what to do with the rest. There were more rooms in Regulus' list, if combined with what was already done, than had been in the entirety of Remus' house when he'd still had one. "Honestly, I'm not sure what else would be needed," he admitted finally. "Our house was two bedrooms, a bath, kitchen with an breakfast nook where we usually ate, and a living/drawing/sitting everything else room." And after that he'd been on the streets or hostels, makeshift tents. It was difficult to imagine two people needing all this space.
