I understand what you mean by that, and it is pretty interesting to take the "we'll see what happens" approach to an RP. I suppose I see what you're getting at as well. I suppose we'll have to see how it turns out.
Though, so far, there is the case of Kiba, well, staring. (Examining the burn on her leg but staring for too long :P) Also, there is the fact that he's so willingly going out of his way to help her, plus I think the next big thing will have some sort of effect. Maybe she might notice the strange things he does (and the fact that he's around her more than the others) and maybe call him out on it?
