I think Emma would be royally pissed at Rumples at this point (he had ripped out Hook's heart and would of killed him if not for Bella). So without being magic/cursed, why would Emma be WILLING (not coerced) to go dark with the QofD/Rumple?

Some sort of common cause (much like the Neverland arc where the villains and heroes worked together)?

Rumple did explain to Bella in his castle, that even though he was the most powerful wizard in EF, it was more about manipulation then just power. So maybe Emma is somehow tricked into going dark (and discovers that she really likes it)?
