"First, you saved me from the Abyss. Then I protected the grave of my dearest friend, but in your quest you came to rob his grave for his power. I was only trying to protect you from his samr fate, but every time you came back. Why did you make me kill you, over and over, until you finally killed me?"

~Great Grey Wolf Sif (2011)

Or at least what I thought he was thinking...
