I agree in the fact that it's most likely a diluted version of the original Dark Curse. Pretty much everyone in the cast has confirmed that Zelena has a Storybrooke counterpart and if she really does have such a dark history with Regina, then either Regina is trapped somewhere, which we know to be false, or Regina's memories have been far more altered than anyone else's.

It seems like the past year + any memories of the WWotW have been deleted from everyone's minds, but considering the Well and Lake Nostos are so entwined, I can't imagine that no one will think of drinking some water from it to remember what the Hell happened.
