Weapon (d4)

Hmm, it seems like they called each other brothers.

Well, they're like brothers. Very close friends, that's all (shhh, girls!). I don't remember either of them having any real brothers. But it doesn't matter, because Grom is dead, and Thrall will be killed (or has already been killed) in the next patch.

P.S. Yes, the addon's plot is very absurd. And if Warcraft doesn't die out, I won't be surprised if, even after the end of the storyline and the next "death" of Deathwing, he again flies to destroy Stormwind (or one of his children will help him, of course, and not Edwin's).
