[Well, at least he doesn't need to do much reading of body language to pick the interest there. He glances over his shoulder momentarily, as if pinning down where he found the scroll by visual memory.]

I can find you the scroll again if it's where I left it, that's probably better than getting it second-hand...wait here a second. [He gives her a cheery wink and heads back the way he came at a brisk walk, because he doesn't want to leave her hanging but also doesn't want to run in a library. It's a few shelves across since he's been in here for a while, but he does remember where he found things that were actually remotely useful, and sure enough, it doesn't take him long to track down the specific shelf in question.

Once he comes back, it's with the scroll under his arm - it's not particularly long, but it's enough to have information on a few spells, at least - and he holds it out once he's in reach.]

Here you go, miss... [Oops.] ...I never asked for your name, did I?
