I thought the situation between Thrall and the Nightelves was handled really good. An Earthen Ring shaman wants him to investigate why the spirits go crazy and Thrall is the only orc with ties strong enough to the Nightelves to even be allowed to go to Hyjal. Under the condition that he brings what is owed. He doesn't know what that is, but he goes anyway and even brings Baine and Calia.
When they arrive Tyrande won't speak to them and he apologizes. She then tells him, where he can shove his apology and the other Shaman starts making them leave, because he thinks she is going to kill them. But Thrall doesn't want to leave it at that without another try. He realizes what it is Tyrande wants from the Horde, promises to bring it, Tyrande nods and smiles and they leave. They get no cooperation from the Nightelves, but none of them get killed either.
I liked the way Tyrande, Shandris and Maiev were kind of a triumvirate speaking with the same intent, but different tempers.
