Thrall had misinterpreted what he thought he owed Tyrande initially, but I had that quoted in the first thread on all this that I made and didn’t think to put it all here as well:
“I brought what you wanted, what is owed,” Thrall said, and at last he saw a spark of life in her eyes. “I bring you the sincere apology of the Horde. We are not a single voice now spoken through the mouth of a warchief, but a whole host of voices. We have formed a council, so that never again will one take power and abuse it as Sylvanas did. As…as Sylvanas used that power to slaughter your people.”
He could swear the moon above glowed brighter, as if the mere mention of the Banshee Queen’s name had ignited its anger.
“Quickly,” Yukha muttered, trying to gather them. “We must go. This was a mistake; I should not have brought you here.”
Baine and Calia allowed Yukha to corral them back toward the path of glittering solid water. Thrall remained, only taking slow, careful steps, never showing Tyrande his back. For his trouble, Tyrande directed her final words to him and only him.
“You will find that justice less sweet than the sorry excuse for punishment you faced, and when this justice comes, there will be no armistice to save you.”
Thrall felt Yukha grab him by the arm and yank. But he did not agree with the shaman’s assessment; it was important and right that they had come. Thrall had thought he knew what Tyrande wanted, that what was owed was his remorse, but now he realized his error.
He easily shook off Yukha’s hand and pressed his fist to his chest to prove his sincerity.
“I will bring what is owed, then. I will not bring words or promises, I will bring you the head of Sylvanas Windrunner.”
The faintest trace of a smile appeared on Tyrande Whisperwind’s face.
“Do it, then, or never seek to speak with me again.”
