My theory:

So every enchanted forest character was sent back with ALL there memories. Emma/Henry forgot everything from the point she gave Henry up for adpotion-when Pan's curse almost hit Storybrooke. I think what happens in the Wicked Witch casts a new curse which re-creates Storybrooke which is why Killian is at Emma's apartment.

Also in the promo Belle says "Do you know who cursed us?" Which it looks like she is talking to Emma/Emma is in the town hall of Storybrooke. There are scenes with Emma & Regina. Plus the BTS filming of Rebecca in Storybrooke, in the promo they say "Invades Storybrooke".

Whale is rushing in a Hospital with Robin Hood saying "What did this too him", probably in reference to Robin's son.
