"Am I crazy for thinking this is suspicious?" "No, because magic" still sounds a little accusatory, though.

Just... from now on I'd appreciate it if you weren't so fast to drop the "M" word when something weird or bad or suspicious happens.

Magic is always a possibility. It's always going to be a possibility, but when I brought up the idea that it could be something else, Kaneda visibly deflated. He was so sure because you seemed so sure.
