Emma had to kiss her true love to break the 1st storybrooke curse (which was Henry) as a condition of breaking the 1st curse, so it didnt matter how many other TL’s kissed, the curse was only set to break when Emma performed it-
Yep, I realize the first curse had Emma built-in as the Savior by Rumple well before it was cast and hence only Emma could break it. But I don’t see anyone else potentially breaking the WW’s curse this time round unless its Regina but idk if she can do that in her cursed state. Plus if you consider the Emma= Dorothy theory and Hook being the only one to have escaped the WW’s curse (still not sure about Rumple), my gut feeling is that the TLK will work similar to Season 1, like you say, the 2 birds, 1 stone thing…wake up and shake up! 🙂
