Mystery = Keeping and hiding secrets, especially when it doesn't make sense. Mystery was key to Once, but not much currently. Hook's cursed hand subplot involved keepuing secrets from Emma. Hook's cursed lips subplot involved keeping secrets from Emma, etc. This is almost a repeated instance in the story when this occurs.

Those are plots that involve secrets. I'm  not saying secrets are whatever, just that they are pretty much the cause and basis or simplification of the subplot.

Baxck to the topic at hand, I think if anything's assured. Emma will accept something in 5a. But it probably won't be to cast aside the DO's powers.
