I still can’t shake the feeling that August is actually there to help Mr. Gold. I think he wants to return the dagger to him. I think the episode will lead us to believe that August is there to kill Mr. Gold, but at the very end of the episode it’ll be revealed that he’s actualy there to return the dagger to him.
I like this theory. We’ve yet to see Mr. Gold and August in a scene together and I think that’s for a reason. Maybe Mr. Gold thinks August is going to kill him because he has the dagger, but then the writers will throw a curve ball at us and August will actually return the dagger to him.
