I don’t know how honorable i consider August after yesterdays episode. I mean he doesn’t seem to care whether or not everyone believes for the sake of everyone else. He only seems to care about Emma believing so that she can help him with his sickness.
I think you have to go back to what he said to Henry at the beginning of the episode “sometimes other priorities assert themselves” I don’t think he can help Emma much if he doesn’t help himself first. If he is who I think he is he does want to break the curse for more reasons than just to save himself but in order to get to that point he has to first save himself.
