Gaze narrowing, Stiles squints at Heiji before turning in a wide circle. Illusions…right, he does remember seeing something like that in his online research. But that begs the question…

“Are you doing anything illusiony now? Is the way you look on the other side fake?”

Probably not the most sensitive wording, but it’s Stiles; when he’s fascinated, he hardly thinks about what he’s saying.
