Sometimes I think that Hemah actually is Danalin, or rather the character Danalin takes in his dreams. As such, he has all the power of a god but does not have a clue how to use it. As Danalin seems to have had a glimpse of a sleeping god stirring when Devon injured him, I tend to think he may have been awakened just enough to start remembering just a little of who he really is. Falling back to sleep after briefly waking up is one of the easiest ways to enter lucid dreaming, so Hemah may have come to understand that he can shape his own dreams now. Hastur is still trying to make his life hard and to turn his dreams dark, but the god of water has a little more say in things than he used to. Of course, he may also now be a bit angry and have a grudge against a few people so his slow awakening could be the first step towards an actual fall. That could have been Mammon's and Hastur's plan all along.
