Frostmourne room

So we follow Jaina and Sylvanas mode where is Frostmourne. Before I get that, I would like to remind you of a few other things we know Blizzcon:

1. Arthas has Frostmourne is a drop Icecrown RAID. Instead, he calculates Ax, hitherto unknown, is called Shadowmourne.
2. Blizzard has a "very specific plans for Frostmourne."
3. Jaina Proudmoore is not mentioned at all spoilers revealed Lore Cataclysm.
4. Sylvanas mentioned Cataclysm leading Forsaken attack Gilneas, which is the basis for a new Battle Ground.

And the last part of my settings consider the following facts about the Lich King:

1. He never goes anywhere without Frostmourne. It is one of the most important powers in the fonts.
2. He considered letting live, because he had "plans for us."
3. He needs to "win". He has not done any great harm to us, because the Wrath Gate, and he needs something, to create a more threatening enemy to him, and not some comedically mustache-twisting villain Cartoon.
4. Arthas Jaina used to love. Original Arthas is mostly or entirely absent, and even his heart has been destroyed. But perhaps the Lich King, there are still some remnants of feelings for her.


All of the above together, leads me to believe that at the end of Dungeon Halls of discretion, Jaina takes Frostmourne (and therefore precious, of course). He probably expected to use it as a weapon against him, a desperate moment, but in fact it is all part of his plans to bribe him over on his side. I think it's Blizzard Writers 'intention to continue the tradition of the Lich King, Arthas will die at the end of this growth, and believe that the Jaina way is to start on the road has been corrupted by Frostmourne (if Ner' zhul people desperate to live in), and eventually become a Lich Queen, even though the king is dead . His plan is to bring him to stand by his side, but in the end he really become his successor.
