Ariel brings Once Upon a Time back to Storybrooke tonight with a mission that may hold the key to beating Pan. But is he one step ahead of the mermaid?

Tonight’s Once Upon a Time starts two new phases of Operation Cobra. The first begins on the shores of Storybrooke, where Ariel makes her way to Belle. As Ariel sheds her fin and uses her newly restored voice, she moves one step closer to finding her Prince Eric. That will have to wait until she completes her assignment to find a magical item hidden in Mr. Gold’s workshop.

On Neverland, the search party regroups from the Echo Cave and make plans to enter the Dark Hollow. If they can find a way to capture Pan’s shadow, they may gain a slight advantage over Pan.

Watch a short preview of tonight’s episode here:

Some of the dwarves enjoy that the Charmings took a vacation to Neverland, but Grumpy keeps an optimistic eye on the sea, waiting for their return. Also keeping an eye on the coast, are two unnamed characters. Judging from their British accents and the one spectacled lad, could these be the Darlings? Regardless, Pan stays ahead of his enemies’ strategy to return to Storybrooke and has more undercover backup in place.
