Well that's an odd question. "Why wouldn't I be?"

But the next question? That one gets a long look before Kageyama decides to stand. He's muddy all down his legs now- unpleasant- and that feels real. Illusions... he doesn't sense anything off, but he reaches forward.

And if Dimple doesn't back off in time he will pinch one of Dimple's red cheeks and tug a bit, otherwise standing there clearly ready to test the illusion quite literally that way.
