"But of course. Your lover deserves quality coffee whenever she wants it." And will let him buy it for her, but that's beside the point. "It'll be nice for me to see her reaction as well. It'll make it easier to decide on coffee for future library study sessions."

His question gets a thorough internal debate as she sips at her mocha. She could easily send him to the library to ask for books about magic there - being part robot means he can read books extra fast, right? - but that also wouldn't give the kind of insight she's talking about. "You need to talk to mages directly. They have all of the knowledge you're looking for." A beat, and then she adds, "And you need to talk to multiple mages from different worlds. Each of them is going to have a different point of view about magic and how it works, because it works differently depending on where the mage is from."

...well, that's probably not going to improve his opinion on magic is it? Nothing to do but accept that, though, seeing as he should have the truth of the matter.
