History WesternAnimation / MyLittlePonyEquestriaGirlsForgottenFriendship

** When Sunset Shimmer and [[spoiler:pony!Twilight visit Canterlot in Equestria, the stained glass windows depicting the Mane Six' heroics in the main series can be seen. They are still partially covered by the lavender that princess Luna put up in ''[[Recap/MyLittlePonyFriendshipIsMagicS7E10ARoyalProblem A Royal Problem]]''.]]

* RealityEnsues:
** In the extended version, the restricted section of the Canterlot Library has a mechanical book catalog. But since no-one has been down there in a long time, the device has not been properly maintained, causing it to fall apart when Sunset tries to operate it.
** Pinkie Pie tries running on the beach while wearing flippers. Naturally, she ends up tripping and face-planting in the sand.
** When the culprit starts [[VillainSong singing]], Sunset uses Trixie as a distraction to search for the Memory Stone. Partway through the song, the culprit notices what Sunset is doing, and immediately stops singing to catch her. [[TalkingIsAFreeAction Singing is not a free action]].
** When Sunset catches up to the culprit in the parking lot, the culprit shouts in frustration how Sunset can know what she knows since she had her memories of the entire afternoon erased. Sunset's friends are nearby and hear everything, proving to them Sunset was telling the truth. Shouting in frustration, especially in a public place, is not a good way to keep secrets and will get you caught.

* BreakingtheFourthWall: Sunset manages to film her and Trixie's entire encounter with Wallflower in the yearbook room, including her VillainSong! When watching the video, Trixie even comments, "Long song..."

* BeachEpisode: The girls visit the beach during the first part of the special, which is where Sunset first learns about the LaserGuidedAmnesia.

** The special's B-plot concerns the girls taking pictures for the high school yearbook. Sunset specifically mentions that, thirty years from now, the girls may not be able to recall details of high school, but they'll have the memories collected in the yearbook to remind them. Later, Sunset uses the yearbook photographs to keep track of suspects for who may have used the Memory Stone. [[spoiler:This causes her to overlook Wallflower Blush until the very end, as Wallflower doesn't have a picture in the yearbook, which also demonstrates how lonely and forgotten she is.]]

* SamusIsAGirl: Clover the Clever, portrayed by Twilight in the [[Recap/MyLittlePonyFriendshipIsMagicS2E13HearthsWarmingEve Hearth's Warming Eve]] pageant in Season 2, is revealed to have been a stallion.

* NoteToSelf: When chasing the original holder of the Memory Stone, Clover the Clever wrote notes to himself to make sure he'd always know who to chase in case his memory was stolen. Sunset uses the same technique to record the culprit then remind herself of the recording.

* PinchMe: When Sunset Shimmer tries to convince herself that her friends not remembering her is a bad dream, she starts saying "Wake up, Sunset, wake up!" But then Pinkie Pie pinches her to show her she's awake. And then Pinkie pinches herself.

* ¨BreakingtheFourthWall: Sunset managed to film her and Trixie's entire encounter with Wallflower in the yearbook room, including her VillainSong! When watching the video, Trixie even comments "Long song".

* CatchPhraseInterruptus: Twilight confronts the villain by trying to say "you don't understand the magic of friendship," but Pinkie Pie interrupts her, telling everyone to "LIGHT HER UP, LADIES!"

* OldShame: InUniverse -- Sunset Shimmer being voted "Biggest Meanie" in her freshman year is certainly something she would rather not be reminded of. Naturally, that's exactly what Trixie takes delight in doing, several times.

* TheyveComeSoFarSong: The opening song is appropriately titled "[[ExactlyWhatItSaysOnTheTin We've Come So Far]]", and it is sung in the internal thoughts of the Mane Seven as they express how far they've come to be true friends and make memories for the yearbook together.

** Later, as she's starting to suspect [[spoiler:Wallflower Blush of being responsible, Sunset grabs Wallflower's hand and reads her mind, confirming that Wallflower is the culprit]].

* IWillOnlySlowYouDown: When Trixie can't manage to use her SmokeOut to get both herself and Sunset out of the room they've been locked in, merely swapping places on either side, Trixie chooses to say locked inside and tells Sunset to go ahead without her.

* {{Adorkable}}: Princess Twilight learns the Canterlot Library has a restricted section she's never seen. She starts hyperventilating just hearing about it, and once she actually gets inside, [[{{Squee}} she can hardly contain her excitement]]. Sunset and Celestia find it adorable InUniverse.

* MundaneUtility: The culprit states when they first found the Memory Stone, they only used it for erasing memories of small mistakes they made, like awkward hellos or any public speaking.

** Flash Sentry's pony counterpart, who has not made an appearance since the first ''Equestria Girls'' movie and the season 4 finale in the main series, makes a silent cameo when Sunset and the princesses enter the Canterlot library. Sunset does a quick DoubleTake upon seeing him.

* DoubleTake: In the extended version, Sunset Shimmer does a double take when she passes by pony Flash Sentry at the entrance of the Canterlot library, apparently surprised that a pony counterpart of her ex-boyfriend exists.

** In the extended version, the restricted section of the Canterlot library has a mechanical book catalog. But since no-one has been down there in a long time, the device has not been properly maintained, causing it to fall apart when Sunset tries to operate it.

* MagicSkirt: Non-underwear example; when Sunset sits down at the beach with her legs in front of her, [[https://mlp.fandom.com/wiki/File:Sunset_Shimmer_writing_%22am_I_nice%3F%22_EGFF.png her sarong somehow holds its position covering her groin and thighs]].

** When Sunset returns to Equestria and is forced to seek Princess Celestia's guidance, Celestia quickly forgives Sunset for her past misdeeds as a SpoiledBrat. The most she does is look stern while waiting for an apology. Then she's all hugs and help.

* FacePalm: After a collective {{Gasp}}, a face-palm is Pinkie Pie's reaction to Rainbow Dash calling their work "just a yearbook."

** When Sunset tries to use pictures on her phone as proof of her friendship with the other six girls, Trixie points out that Sunset manipulated photos in [[WesternAnimation/MyLittlePonyEquestriaGirls2013 the first film]].

** When Sunset Shimmer reads the memories [[spoiler:inside Wallflower Blush's head]], we get a different viewpoint of events from previous movies ([[WesternAnimation/MyLittlePonyEquestriaGirls2013 the Fall Formal]], [[WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks the musical showcase]], [[WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames the party before the Friendship Games]]...)

* FacePalm: After a collective {{GASP}}, a face-palm is Pinkie Pie's reaction to Rainbow Dash calling their work "just a yearbook."

-->'''Applejack:''' I prefer to take selfies myself... ie.

** The special prominently features a subplot about the school yearbook and the girls taking pictures for it. Sunset mentions that they may forget what's happened in thirty years, but the yearbook will preserve it for them.
** The magic used to steal memories is visually represented by camera film strips.

** Sunset keeps track of suspects using the yearbook photos. [[spoiler:That Wallflower has no photo in the book both causes Sunset to overlook her until the end, and is symbolic of how lonely and forgotten Wallflower feels.]]
** Sunset realizes the Memory Stone's hiding spot, and who has it, from a photograph she sees in the culprit's possession.

* DisproportionateRetribution: Trixie's reaction to Sunset refusing to put her in the yearbook as the "Greatest and Most Powerful-est" is to swear {{Revenge}} on her. Downplayed as she never attempts it, instead helping Sunset's goal of regaining her friends.
** [[spoiler:Played straight with Wallflower Blush as she strips the memories of Sunset's redemption from the entire school because she felt [[ForgettableCharacter ignored]].]]

This version contains extra footage that was cut from the broadcast version.

* TheComicallySerious: Wallflower's deadpan exasperation at no-one noticing or remembering her is a RunningGag.
