I personally wonder whether Headmaster Cross is a vampire himself. If not then how did he end up being so closely acquainted with Kaname - and possibly the Clan Family themselves? What are his connections to all this because we can clearly see that the relationship between him and Kaname appears to go a ways back - so much so that Kaname would actually trust him enough to hand Yuuki over to his care. Also, I wonder if Kaname's insistence on co-existence between vampires and humans stem from whatever happens before that snowy day - is it for Yuuki's sake? or is there another reason?
Ichichou (spelling?
) did warn Kaname that there are some vampires in the school who are "listening to others". Interesting. Plus, he also said that the others are enjoying themselves here - then where were they originally from?
