The promo represents Wicked Witch as invading Storybrooke. That would suggest that she didn’t cast the spell that recreated it.
I wonder if this is true?
It depends on what the promo actually IS.
It could just be a reminder that #WickedIsComing to SB and ONCE in general. It may not actually signify anything plot wise.
Or it’s a giant clue
lol. It was vague to the point of absurdity.
