"Light's different. Moon's different."

It's hard to articulate what he means by the light being "different." Even using English wouldn't help him here, because it's some subtle sort of... wrong. The fact that the moon is in a different place only accounts for some of it, because if it was the same light source then it should feel the same. This... doesn't, but he's never dealt with anything like this before so he can't quite say why he's having trouble. Instead, he just mutters "gross" under his breath as he tries to manipulate the light in the area.
