deathwing = bolvar???ok now tirion knew the undead plague was bad. I mean he just killed like thousands of the undead so he knew they were evil and very dangerous. But when he got to kill the undead leaders once and for all, and he killed the lich king he just said he would make someone else lich king. Now this doesn't make any sense i mean if he wanted the undeads gone forever then why would he give someone else power and keep a lich king in power i mean if there is a lich king then there are still undead plagues. So why would he do this unless he is secretly bad guy
and i think it isn't coincidence that like a week later deathing broke azeroth in half. I think it must be the new lich king that gave deathwing power i mean he was trapped for thousands of years but suddenly he breaks free once tirion lets a new lich king have power? It is very odd. Tirion is obviously deathwing's human form. Deathwing was under the earth but he controlled tirion so tirion could get the undead power and then use that to help deathwing escape and kill all humans. So now that he has undead power he is willing to break free because he can use it. And because tirion is deathwing then in cataclysm we will have a big fight with tirion when he becomes deathwing.
I am sorry to spoil cata for you and i know it is supposed to be big surprise but i needed to post it to tell other people. I can't believe i am the only one to figure this out.
