Looks like they may try to initially pin the new curse on Regina (understandable, though completely wrong).

But there is no way that anyone cast the original dark curse. Regina had to retrieve it from Maleficent before originally casting it in the first place, and Pan had to steal it from Regina before his failed attempt. And finally Regina destroyed it. So the original curse is gone.

And there is only one person that I know that would be able to come up with a second curse. I think Zelena has Rumple under control somehow, and it was Rumple that cast the Curse (on Zelena's behalf).
