"Oh, I'm not upset. The books in the library are there for everpony to enjoy. I actually read it before. A great read. This time, however, I needed it for a reference. I was waiting them to receive a second copy so I could own one. I may be good at the stars, but without my copious notes and extensive library on hoof.... Well, let's just say, I'd forget my head if it weren't screwed on tight." he chuckled "And besides, I always prefer to be exactly right on my research with not a dot on the i or cross on the t missing.

Your cutie mark is two stitched hearts, so my first guess is relationship counseling, but yours is.... oh, it's on the tip of my tongue.... I don't know, I recognize it's ancient unicornian, but I'm at a loss- wait!" he pulled out his book, thumbed through it a moment and pointed, more for himself than anything "Yes!
