So, Nonnie is this what I am hearing? To break the curse Emma has to die but it sounds as thought FTL would be restored, so SW and PC could not live HEA in FTL without Emma; but if things remain as they are, the curse weakens and everyone remembers because of Emma’s presence, but they cannot return to FTL as long as Emma is alive which technically keeps everyone from living HEA. Is that what you got? So either way, there is no HEA for SW and PC. Thus the “idea” of the curse is fulfilled.
Mr. Gold doesn’t really want Emma dead, though. He wants to be free to find Bae. I am coming round to the idea that Bae is Henry’s father and Emma’s true love. That would throw a wrench into things for Mr. Gold now, wouldn’t it?
