The Wicked Witch has come to Storybrooke on Once Upon a Time Season 3 — and she brought all the Fairytale Land characters back with her. Now our heroes have to figure out who has cursed them again — without the help of their memories from the last year! Season 3, Episode 13 ("Witch Hunt") should be fun.

What can we expect now that Emma has her memories back? We've gathered all of the biggest spoilers and clues about the episode right here.

Official Synopsis

First, let's start with the official synopsis of the episode, which gives us a lot of info about the next chapter in this magical saga:

Emma arrives in Storybrooke with Henry and reunites with her friends and family, only to discover that no one remembers how they were transported back — or the past year they had spent back in Fairy Tale Land. But Emma is sure that someone in town is responsible for this new curse and teams up with Regina in an attempt to uncover their identity. Meanwhile, in the Fairy Tale Land that was during the past year, Regina, with the aid of Robin Hood, attempts to break into her castle, which has been overtaken by the Wicked Witch.

Emma Is Back in Charge — And There's Trouble Afoot

Next, there's this sneak peek, which gives us even more to go on:

There are several things worth noting. First, it looks like Emma quickly slips back into a leadership role. That's good, because the town needs help — there is a "monster" that abducts people when they try to cross the town line. Based on the promo, we're thinking that "monster" is a flying monkey.  

Let's Talk Regina

In that sneak peek, the townsfolk are quick to turn against Regina, and there's even a Regina and Emma face off. Still, we know from the synopsis that the two team up, so this misunderstanding can't last long unless, of course, this fight comes after the team up the synopsis is talking about.

Meanwhile, we can expect the Regina and Robin Hood plot to involve "heightened circumstances." Should be fun!
