We're only a few weeks away from the  Once Upon a Time Season 3 midseason premiere — Season 3, Episode 12 ("New York City Serenade"), which airs on March 9 — but until now there has been very little footage from the new episodes. Thankfully, that's all change with a new midseason promo that gives us plenty of new scenes to contemplate as we await the next episode.

The main focus of the promo is the new Big Bad, the Wicked Witch of the West, who is shaping up to be a formidable foe of a different kind than the tricksy Peter Pan. So, what do we learn about the green witch and her plot against our heroes? We've taken a close look at the promo to see what it reveals.

1. Fairytale Land! At :01 we see Charming back in Fairytale Land. We know from the season synopsis that the characters eventually lose their memories of what happens in Fairytale Land between the winter finale and spring premiere, but it looks like we'll at least get a glimpse, if only in flashback form.

At :05, we see Snow and Regina, also in Fairytale Land, looking upwards in distress. Based on the flying monkeys we see elsewhere in the promo, we wonder if they're being attacked by the Wicked Witch's henchmen.

2. Oh yes, flying monkeys. At :07 we see a flying monkey in Storybrooke, grabbing someone just before the town line. Does the monkey force the person to cross the line — which would probably have a negative effect, based on the way the curse worked in the past — or is it stopping them from doing so? It looks like the former, but it's hard to tell. We wouldn't be surprised if this is linked to someone being rushed into the hospital at :15. (Also, is that Dr. Whale we spot? Yay!)

3. A person disappearing in a cloud of green smoke. Is it the Wicked Witch herself that we see disappear in the cloud of green smoke at :11, or does she have a helper?

4. Regina makes connections. At :12 we see Reinga talking to Snow and Emma — yes, Emma, which means she does make her way to Storybrooke — contemplating the clues. "Green smoke. And now they're flying monkeys in this town?"

5. The hunt for the witch. "So how do we find this Wicked Witch?" Charming asks at :15, which we're guessing is going to be one of the team's major tasks, at least at first. After all, you can't fight her if you can't find her. At :15, we see Charming, Emma, Hook, and Regina teamed up, opening some sort of trap door. It look like Emma is carrying a gun. The hunt is on!

6. The witch and her potion. At :16 we see the witch holding a potion out to someone else, who appears to have hairy hands. One of the flying monkeys?

7. Regina gets her magic on. Meanwhile, back in Fairytale Land there's a shot of Regina wielding some magic while Snow, Charming, and the gang look on (:18).

8. Charming in trouble. At :19, there's a shot of Charming passed out. A hooded figure, much like the one that disappears in smoke at :11, is approaching him from behind. That makes us nervous...

9. The witch vs. Regina. Clearly, whatever the Wicked Witch is doing in Storybrooke has its root in Fairytale Land. At :21 we see her tell an Evil Queen costumed Regina, "I'm going to take everything away from you." "Bring it," Regina replies. Awesome.
