'''Season 3, Episode 6''':
!Ariel
Back in the Enchanted Forest that was, when Ariel saves Snow White from drowning in the ocean's depths, Snow returns the favor by helping her new friend get acquainted with Prince Eric, with whom she has fallen madly in love. Meanwhile, Emma, Mary Margaret, David and Hook attempt to save Neal, who is imprisoned in one of Pan's encampments, and Regina and Mr. Gold begrudgingly team up to find a way to take down Pan.

!Tropes
* AbsenteeActor: Henry.
* AesopAmnesia: In the Season 2 finale, Regina expressed regret that everyone saw her as the Evil Queen. Now's she's more than willing to embrace that title.
* ArbitrarySkepticism: For some reason, Ursula the sea godess is a myth in the ''Enchanted'' Forest. Justified, by the characters InUniverse as she hasn't been seen for over a thousand years.
* DarkSecret: In order to rescue Baelfire from a cave, Emma, Snow, Charming and Hook all have to divulge their deepest darkest secrets to make a magical bridge appear to cross a chasm to reach him.
** Hook reveals that Emma makes him feel like [[SecondLove he can move on from the loss of his first love]], [[AllLoveIsUnrequited even though Emma loves Baelfire.]]
** Snow White reveals that she wants to have a second child with Charming to experience parenthood in the way they never got to with Emma.
** Charming reveals that [[YouCantGoHomeAgain he will die if he tries to leave Neverland]] because of the magic waters sustaining him only work in Neverland.
** Emma reveals to Baelfire that she has hoped he really did die because seeing him again would [[LoveHurts bring back all the pain that comes with loving him.]]
* DidWeJustHaveTeaWithCthulhu: Pan confronts Rumpelstiltskin again and offers him an egg in a basket and the chance to leave Neverland to be with Belle...all he has to do is forget about Baelfire and Henry and save his own skin.
* DrillSergeantNasty: Regina is a mild one, when trying to teach Emma to use her magic to create a camp fire. Notably she tells Emma to focus on anger to create the fire, in contrast to the brief tutorial Rumple gave Emma in "The Miller's Daughter" where he encouraged her to use more positive emotions to cast the protection spell.
* EntitledBitch: After ruining her budding romance with Eric, Regina has the ''nerve'' to ask Ariel to help her and Rumple in their plans to defeat Pan. In her defense, she clearly believed giving her back her voice, a permanent set of legs, and the chance to be with Eric after all would make up for what she'd done; counting against her however is actually thinking Ariel would believe she could trust her to keep her word this time.
* GodGuise: Regina impersonates Ursula, who is actually a benevolent deity, in order to trick Ariel. The real Ursula who was presumed to be a myth even by mermaids turns out to be very real and is very displeased at this.
* KickTheDog: Regina taking away Ariel's voice at the end was just ''cruel''. Pan not only twisting the knife regarding [[{{Foreshadowing}} Rumple ever forgiving his own father]] but also suggesting he replace Neal by having a new child with "fertile" Belle is ''damned'' low.
* LargeHam: In-universe, Regina as Ursula, with Lana Parilla doing her best Pat Carroll impression.
* LivingStatue: Ursula possesses a bronze statue of herself to have a little chat with Regina.
* MythologyGag: The Ariel flashback is full of little gags. Like a reference to [[Disney/{{Aladdin}} Agrabah]]. Or her being a collector, or the dance being called "Under the Sea", or Regina/Ursula saying she could be "part of his [Eric's] world"...
* TheOnlyOneAllowedToDefeatYou: Regina tells Rumpelstilstkin that he doesn't have to worry at dying by Pan's hand because she claims the right to kill him in the end.
* OurMermaidsAreDifferent: They are able to travel between worlds, and are able to grow legs during Ursula's festival
* RealAfterAll: Ursula, much to Regina’s shock.
* ReedRichardsIsUseless: If Ursula is really a powerful sea-goddess, why couldn't she have given Ariel back her voice? She knew what Regina did.
* TheReveal: The Belle who has been comforting Rumple all this time is actually Pan's Shadow. Although the fact she was urging him to go back to Storybrooke with her by taking her hand (implying flight, the way the Shadow travels to and from Neverland) and there have a child with him (something she had never expressed before this but which Pan had in fact suggested) were some subtle clues something wasn't quite right.
* ScrewThisImOutOfHere: Regina, fed up with the lack of progress in getting Henry back, decides to strike it out on her own when the others decide to rescue Neal, which she thinks is a waste of time, even though they need him to read his star map so they can ''leave'' Neverland once they get Henry back.
* ShatteringTheIllusion: The illusion of Belle returns and proves to have been Pan's shadow all along playing tricks on Rumpelstiltskin. Regina exposes the trick by choking the fake Belle into reverting to Pan's shadow form.
* TakeAThirdOption: Regina and Rumpelstilskin formulate a plan to trap Pan in a FateWorseThanDeath using a magical MacGuffin that Rumple left back in Storybrooke. Regina convinces Ariel to do the job of going to retrieve it.
* TooDumbToLive: Regina, for striking off on her own, even though Hook's knowledge of Neverland is what has been keeping her and the rest of the group alive. Taken UpToEleven in the flashback, where Regina decides to impersonate Ursula, who is a sea ''goddess''. The ''real'' Ursula is ''ticked'' off by this.
** YMMV on present-day Regina, given that the group of good guys have so far spent the season nearly drowning, being poisoned, walking into traps, whining about relationship issues, and in general wasting time. By teaming up with Rumple, Regina's managed to get herself a Neverland guide who a) has incredibly powerful magic and b) with her encouragement, is actually willing to do something.
* VillainDecay: Regina invokes this about Rumpelstiltskin and herself, considering all they have been doing is skulking around Neverland wasting time. She reminds him that he is [[TheArchmage The Freaking]] [[PhysicalGod Dark One]] and she is [[GodSaveUsFromTheQueen The Evil Queen]]; both of them are the most powerful magic users in the entire world and should start acting like it.
* YouHaveFailedMe: Regina pulls this on a guard who left Snow White for dead.
