Hey, at least she didn't say it out loud. :p
A less serious Niks might even use it.

Evvie: "You half-dragon skeleton?"
Less-serious-Niks: *rolleyes* "I raise from my grave to curse youuuuu."

In a more serious note....Is Evvie jump kicking? I think Niks' a bit too tall for her to just kick in the torso without jumping.
