"Yes, there's a small section that will be off limits, but I have doubt you'd be interested in my spell books anyways." Or that he'd understand them. Magnus wanted to be sure though. He didnt know how much education Alec did have after all. "But yes, it's a rather large room. I have a love of the written word as well and usually end up adding to my collection frequently."
He smirked a little at Alec's snap and made a point of looking him over again, just to torture him a bit. "Well if that's an offer to watch..." He let the words trail off so the boy could sweat it out for a moment. "I will have to decline. I must ensure dinner is almost ready. I'm starved." He was polite in bowing out so as not to make him too uncomfortable. He wanted Alec blushing, not terrified or too upset about his innocence...yet.
