[ A place like this— foreign and uncertain- definitely hints at secret passages, but Minato is surprised to hear that what Merlin is looking for is a library. It's the furthest thing from his mind, whether he'd just turned up here or in the many years of schooling he's had and very rarely finds himself in a library. Bookstores are a little different, but libraries...

I wouldn't know about either of those. I guess a library's easier to find, though... if you look for a book first, and ask someone where they got it. [ That's assuming nobody carries books around with them. Who does? Nerds. ]

If it's history or something you want to research, asking somebody would be easier too, wouldn't it? [ Someone other than him; sorry he's so unhelpful, and he realizes this, dropping his hand and returning it to his pants pocket. ]
