He teleports to the cafeteria.
"She spent a while reading me my own specs first, though," he says. "Accurately. Down to the shape of a form I've never displayed in this world."
"Okay, how does divinatory wizardry work, then? What would she have been able to find out, what wouldn't she?"
"And? Aren't you the one who was all excited about what things your magic could tell about my magic? If some girl's got a spell that'll let her walk around telling me every time my mana goes up or down and what I'm using it for and all about the parameters of cosmetic alterations to my forms and step by step how to get into an obscure maintenance mode I didn't know I had and use it to wipe out control codes I didn't know I had either, don't you wanna know what spell it was so you can cast it yourself?"
"I don't know what you call verifiable, but I feel pretty verified. The maintenance mode is there, I can use it now that I've done it once - it's grown in, not built in, arose naturally instead of being designed as part of my systems, that's why I didn't know about it."

"Okay, but between 'crazy person who invented spells to tell her all the stuff her crazy is supposed to be telling her, including really obscure things about a kind of magic she can't possibly have heard of before today' and 'actually her magic just works like she says it does', you can see why I might go for the second thing, right?"
