Here is a widely off the waa theory on the new curse
I think the curse comes as a consequence I think during their confrontation in SB Pan either threatens or warns Rumple that if he kills him there will be consequences not just for him but for everyone in SB. I suspect that Pan intentionally wants to curse everyone who wanted him stopped there in SB and more importantly everyone who stopped him that was in NL which means Emma, Neal, Henry, David, Snow, Rumple, Hook, Regina, Tink, Wendy, The Lost Boys, The Darling Brothers, Ariel, Belle, Team 7, etc you get my point.
Now I know Adam has said it’s not what you think. Either it’s AU FTL or NYC is AU or it could be a dream. But I have to say this has got me a wee bit nervous about 312
