"Do you even know what you're looking for?"
"Is that a real question? As you've so kindly reminded me time and time again, the library is my second home."
"Then why have we been aimlessly walking up and down the aisles?"
"Look, Malfoy, I can do the research on my own. I promise that Professor Binns won't know of your lack of assistance. I just don't know exactly how Madam Pince has organized this particular section of-"
"You mean to tell me, in all of your years inhabiting the library, that you haven't spent much time in the restricted section? Surely you're kidding."
"I've done my fair share of wandering these corridors, thank you very much. I just haven't had to dive too deeply yet."
"Wait, you're a 7th year and you haven't explored all of the 'knowledge' at your fingertips?"
"What are you getting at?"
"Wizarding Karma Sutra, Granger. I should have known. Come on, don't make that face. It's "restricted" for a reason."
"Yes, for dark magic and the like; not to help along the sexual endeavors of a horny teenage boy!"
"Don't knock it 'til you try it, Granger. And I'll have you know, I have yet to place my hands on said book. Which is why I'm going to search these shelves for something far more interesting than information on the Goblin Rebellion of 1612. Honestly, as if I even care-"
"Don't, Malfoy. It's an important part of our education-"
"Seriously? You want to learn about wretched little Goblins when you could be exploring the endless possibilities of magically heightened sexual pleasure-"
"D-don't call them that! A-and I don't need help in that department. I can manage just fine on my own."
"Are you blushing, Granger? Gods, you are! You're turning shades faster than that little Weasel-"
"Is this conversation over? Unlike you, I'm actually concerned about our grade. It's truly unfortunate that we've been stuck together, but I won't let the likes of you be detrimental to my outstanding performance-"
"Yawn, Granger. Fine, yes. I'll stop with the lollygagging if you promise to help me find the book. No, not the Goblin nonsense. Yes, that book. Stop making that face! I think you'll be very happy to further your education in that department. Pride in your extensive knowledge and all that. So, agreed then? I'll take the pink tinge on your cheeks as a yes. Let's get to the more interesting texts, shall we?"
