ET has a special sneak peek at the Season Four episode 'Fall,' 4x10 in the ABC 'Once Upon a Time' canon. For those who have been following along - and you better not miss too many episodes if you want to stay up to speed on the convoluted plot - right now it is all about the evil truth of the Spell of Shattered Sight, The Snow Queen's (Elizabeth Mitchell) plan, and her potential allies in the destruction of Storybrooke.
There is a good collection of official ABC stills here that will give you even more insights into the episode.
In the Sunday, November 30th 2014 episode, "Fall," the Spell of Shattered Sight approaches Storybrooke. Mary Margaret and David rally the residents to prepare for the curse while Belle and the fairies work together on an antidote.
Gold, with Hook along as his zombie-fied servant (Gold took Hook's heart to free himself from the Dagger), sets about trying to craft a separate solution for himself. Regina and Robin Hood prepare for the worst to happen. With the help of a locator spell, Emma and Elsa search desperately for Anna. Meanwhile, back in Arendelle, Anna and Kristoff awaken to find that their own kingdom is once again in danger from the forces of destruction.
The romances involving the three female leads - Emma, Regina, Mary Margaret - are in full swing at this point, with lots of hugging and kissing. Hey, it's better than standing around giving everyone evil glares for 60 minutes every week! These guys have probably been begging for some kind of love interest to give them something to do for the past three years.
