I think Kaname is trying to be Lelouch from Code Geass, clearly. ["I will make two clans that are enemies to hate me so they can unite themselves to destroy me and Ill carry all my sins alone and everyone will be at peace, amen"].
Secondly the only sure I have is that someone will die to end the triangle, and it will be probably Kaname, since he wants to die so much and be the tragic hero. He could easily beat Zero, but he will not do it.
And we will have a Zeki ending. the worst ending possible I must say, because although Zero is my fav chara and the sole and only reason why I keep reading this manga, I hate endings "Im going to stay with the one that´s left because the other one is dead or went away" type. Im sick of those ends (aka, Moe Kare, Inuyasha etc...).
please Matsuri sensei...be a bit more original =_=
