I know its too early, but when it was revealed that Emma will be the Dark One in Season 5, I can't think of another storyline that will top it. I mean, it's the show's main protagonist that will fight darkness itself, and I don't see another random storyline that will just pop up after her defeating darkness, unless the writers will drag this up to the next season. With this in mind, since a sixth season is possible, what do you think will be its storyline?
