Without hesitation, Kira moves into a defensive position. There is no flinching. No appearance of doubt. This isn't her friend.

"If I have to." She doesn't want to. She doesn't want to hurt (kill, is whispered internally) a person with Stiles' face. But then again, she did it before, didn't she? Sort of.

She can do it again if she has to.

"If all you want to do is go on your way, I won't stop you. But if you think that I'm some kind of chew toy, you're going to be in some severe disappointment."
