So recall how Unulaq has some kind of agenda in the spirit world. Recall that Vaatu is trapped in the Spirit world as well.

Now hear this: I think Koh (the face stealer) is guarding Vaatu. Because that's why Eska and Desna display no facial expression. Because Unulaq has been training them to confront Koh.
