[[NotHimself Or are they?]]]]

->'''Twilight Sparkle:''' "Princess Celestia cordially invites you to the wedding of Princess Mi Amore Cadenza and..." ({{gasp}}) ''...[[RememberTheNewGuy my brother]]?!''

-> Written by Meghan [=McCarthy=]

Twilight Sparkle is picnicking with her friends, when Spike receives a list of instructions from Princess Celestia for the Mane Six to organize and support a wedding in Canterlot. They are confused until Spike produces the previous message announcing that Princess Mi Amore Cadenza is marrying Shining Armor -- Twilight Sparkle's ''older brother''.

Twilight takes it very hard that her brother, with whom she was very close, didn't give her the news in person -- or even tell her he was seeing someone. She fears their relationship will never be the same now that she lives in Ponyville and he's getting married. Her worries preoccupy her all the way to Canterlot.

When she confronts her brother, he is very happy to see her and clarifies her misunderstanding. The unknown "Mi Amore Cadenza" is actually Twilight's much-beloved foal-sitter, whom Twilight knew as "Cadance". Shining Armor goes on to explain that, due to a threat to the city, all his concentration is going into the constant upkeep of a spell of protection for Canterlot. Once he asks Twilight to be his Best Mare, Twilight is more than mollified about the wedding; she's pleased, and very happy to see her old friend -- until Cadance arrives and brushes off the SecretHandshake from their youth. Twilight is set on edge by this cold greeting from her old friend, but lets it go ...

...until she sees Cadance feign appreciation of Applejack's cooking, sneer at Rarity's beautiful wedding gown design, and diss Pinkie Pie's reception planning. Twilight sits down with her friends and voices her concerns, but the other five ponies assure Twilight it's just bridal nerves. Unconvinced, she goes to talk to Shining Armor but before she can voice her suspicions, Cadance arrives and demands his attention. Twilight eavesdrops on the ensuing conversation between the Princess and Shining Armor. Peeking through the door, she witnesses Cadance cast a spell on Shining Armor, cementing her concerns.

As the rehearsal for the wedding begins, Twilight declares that Cadance is ''evil'' and describes all she's seen, including the spell. To Twilight's dismay, nopony treats her suspicions with credulity. Cadance bursts into tears and runs from the room. Shining Armor is then angry with his sister because of her actions and reprimands her, contradicting each of her accusations (he explains that Cadance's magic was apparently to heal him from the migraines he develops from the stress of repeat-casting the barrier over Canterlot) and that she shouldn't bother to come to the wedding at all.

The Mane Six and Princess Celestia walk out with disappointed glances at Twilight, with the latter coldly telling her, "You have a ''lot'' to think about," before leaving Twilight alone to contemplate her actions. Fearing she has irreparably damaged the relationship with her brother, Twilight reflects sadly on losing her [=BBBFF=][[note]]Big Brother Best Friend Forever[[/note]]. Cadance suddenly appears in the darkened hall, to whom Twilight murmurs "I'm sorry." The Princess gives a warm smile... before her eyes flash malevolently green.

-->'''Cadance:''' You '''will''' be.

Hellish green flames encircle Twilight and drag her down through the floor as Cadance gives an evil grin! She really ''is'' evil, and who knows what has become of our little pony heroine!

!!Continued in "[[Recap/MyLittlePonyFriendshipIsMagicS2E26ACanterlotWeddingPart2 A Canterlot Wedding Part 2]]".


* AffectionateGestureToTheHead:
** Shining Armor gives Twilight an affectionate hoof noogie during the {{Flashback}} accompanying the "[=B.B.B.F.F.=]" song.
** Princess Mi Amore Cadenza reaches out with a hoof and strokes Twilight's mane right before casting the fire circle and sending her under the castle.
* AesopAmnesia: Once again, the ponies forgot the lesson learned in "Lesson Zero": do not ignore your friends' concerns as overreacting even if they seem that way. Twilight also forgot the lesson she taught Pinkie Pie, ironically in the previous episode, about jumping to conclusions without getting evidence.
* AlphaBitch: How Princess Mi Amore Cadenza acts. Except it's not her.
* ArtShift: During Twilight's DarkReprise of her earlier song.
* {{Backstory}}: Due to the RememberTheNewGuy nature of Shining Armor and Cadance's debuts, Twilight explains some of her backstory to ease the two in.
* BarrierMaiden/BarrierWarrior: Shining Armor serves as one here, as he's the only one who could erect a force field strong enough to protect Canterlot against an unknown threat, and the force field requires constant upkeep from him. Without him, the unknown threat would have open access to Canterlot.
* BehindTheBlack: While Twilight and her friends are gathered around a table, Applejack peeks over Twilight's head so she can be seen... by the camera.
* BestWoman: Shining Armor asks Twilight to be this. Until she accuses the bride of being evil.
* BilingualBonus: Princess Cadance's full name is Mi Amore Cadenza, which is like "my love cadence" in a mix of Italian and Spanish.[[note]]It would be "Il mio amore Cadenza" in Italian, and "Mi Amor Cadencia" in Spanish.[[/note]] This is fitting given her cutie mark and special talent.]]
* {{Bridezilla}}: Mi Amore Cadenza acts like this, and Rarity theorizes it's due to the wedding planning pressure. She did want her day to be perfect, but she was also literally not herself.
* BrokenPedestal: Twilight's first reaction to being told her brother is marrying Cadance is nothing more than absolute glee that her childhood friend and the "best foalsitter ever" is marrying her brother. Then she sees the {{Jerkass}} Cadance has become ([[RebuiltPedestal or seemed to]]). In the end, thanks to Cadance, she ends up becoming this in everyone else's eyes to some degree.
* CallBack:
** Applejack is the caterer for the wedding like she was for the Summer Sun Festival in [[Recap/MyLittlePonyFriendshipIsMagicS1E1MareInTheMoon the very first episode.]]
** Fluttershy's bird choir makes a return like in "[[Recap/MyLittlePonyFriendshipIsMagicS1E1MareInTheMoon Mare in the Moon]]" and "[[Recap/MyLittlePonyFriendshipIsMagicS1E5GriffonTheBrushOff Griffon the Brush Off]]".
** Twilight is the organizer like in "[[Recap/MyLittlePonyFriendshipIsMagicS1E1MareInTheMoon Mare in the Moon]]" and "[[Recap/MyLittlePonyFriendshipIsMagicS1E11WinterWrapUp Winter Wrap Up]]".
** Rainbow Dash is called to perform her [[Recap/MyLittlePonyFriendshipIsMagicS1E16SonicRainboom Sonic Rainboom.]]
** We see that same kind of force field that Twilight conjured [[Recap/MyLittlePonyFriendshipIsMagicS2E2TheReturnOfHarmonyPart2 in "The Return of Harmony Part 2"]] and [[Recap/MyLittlePonyFriendshipIsMagicS2E23PonyvilleConfidential in "Ponyville Confidential"]] except this time Shining Armor's the one who made it. She almost certainly learned it from Shining Armor, as Twilight has displayed the ability to [[Recap/MyLittlePonyFriendshipIsMagicS3E1TheCrystalEmpirePart1 learn a spell after only one viewing]].
* TheCameo: Luna appears several times throughout the two-parter, though she has no bearing on the plot.
* CareBearStare: One of Cadance's powers is the ability to spread love -- she uses it on an arguing couple, to make them instantly drop the (rather dumb) thing they were fighting about.
* CassandraTruth: ZigZaggingTrope. Everypony dismisses Twilight's claim that Cadance is evil but then the next episode reveals that the jerk-Cadance was an impostor.
* ChasteToons: Mi Amore Cadenza is Celestia's niece, despite Luna having come down from the moon only short while ago. Celestia adopted her, as explained in [[AllThereInTheManual Twilight Sparkle and the Crystal Heart Spell]] novelette.
* ChekhovsGun: Cadance's signature spell (Seen in flashback) is to inspire love in its target. This becomes very important in the next episode
* CliffHanger: Twilight is captured!
* ComicallyMissingThePoint: When Cadance dismisses Pinkie's plans as perfect for a six year-old's birthday party, Pinkie thanks her. Also see InsultBackfire.
* ContinuityNod:
** Pinkie plays the [[Recap/MyLittlePonyFriendshipIsMagicS1E10SwarmOfTheCentury Parasprite Polka]] while demonstrating to Mi Amore Cadenza.[[note]]She was using it to portray The Chicken Dance, an old wedding tradition in some circles.[[/note]]
** Twilight does her joyful jumping around thing both as a filly and an adult, like she did in [[Recap/MyLittlePonyFriendshipIsMagicS1E23TheCutieMarkChronicles ''The Cutie Mark Chronicles'']].
** The [[Recap/MyLittlePonyFriendshipIsMagicS2E3LessonZero Smarty Pants doll]] makes a brief reappearance in Twilight's flashback to Cadance. Twilight is pulling Smarty Pants out of a toy chest with her magic just before Cadance walks into the room. When Twilight sees Cadance, she drops Smarty Pants to get a hug. Smarty Pants is even seen with her quill and notebook!
** In the same scene, near the roof is a kite exactly like the one Apple Bloom tried to learn to fly in [[ReCap/MyLittlePonyFriendshipIsMagicS1E12CallOfTheCutie Call of the Cutie]].
** Nod to "[[ReCap/MyLittlePonyFriendshipIsMagicS1E14SuitedForSuccess Suited For Success]]", possibly mixed with CharacterDevelopment. This time Rainbow Dash is able to articulate what she doesn't like about her dress and how it can be improved, and Rarity is more pleasant about making changes to it.
* ControlFreak: Mi Amore Cadenza -- understandably, since it's her wedding and she has to do all the preparations by herself with her groom tied up with the upkeep of the protection spell. Though it's not the real princess, who is shown to avert this trope when it happens in the next episode.
%%* CreatorCameo: [[http://www.ponibooru.org/post/view/170412 The female Pegasus]] in the flashback is a [[http://sibsy.deviantart.com/#/d4wnsuy creation of SIBSY]].%%
* CrocodileTears: Cadence fake-cries after Twilight accuses her of being evil in front of everyone.
* DamnedByFaintPraise: Twilight sees Princess Cadance's actions towards the other ponies like this, though none of the other five notice it.
* DarkReprise: Of Twilight's "B.B.B.F.F." song, after she's alienated her brother.
* DeflectorShields: The whole city of Canterlot gets one, courtesy of Shining Armor.
* DisappointedInYou: Celestia's response to Twilight Sparkle's apparently petty & jealousy-fueled accusations towards Cadence. Too bad Twilight turned out to be right.
* DoesThisRemindYouOfAnything
** Cadance trying to dictate what Shining Armor can or cannot wear and hurting him when he disagreed with her made their relationship creepily abusive.
** Watch the scene where Shining Armor argues with Twilight for the first time as many times as you like. It would soon start sounding like a SiblingRivalry conversation.
* DraggedOffToHell: In a kid's show, no less! Cadance's spell to drag Twilight down into the mines brings this to mind.
* TheDulcineaEffect: Twilight's friends leave her for and defend a pony that they only met for about a day or two. Rainbow Dash's case is larger, due to her representing UndyingLoyalty and claiming that she barely ''spoke'' to Cadance.
* EtTuBrute: Shining Armor and Princess Celestia's disappointment towards Twilight for accusing Cadence as evil, and Twilight's friends leaving her afterwards plays with it. Although the real Et Tu moment is when Twilight realizes that Cadence is really evil. Confirming her suspicions, and moments before the evil bride drags her down to the underground mines. Ultimately reversed in the next episode for the former case.
* EyeRecall: A rare inversion occurs when Twilight is remembering her memories with Cadance; the camera zooms ''out'' of young Twilight's eye when the flashback begins, then it zooms ''in'' on her eye as it cuts back to the present.
* {{Fainting}}: Rarity does it twice, once when she found out she was making dresses for a princess' wedding and again when she learns that she'll be making dresses for the wedding of a princess ''and'' the captain of the royal guard. Twilight magically produces a pillow for the second one.
* ForceFieldDoor: The only way anybody can get into Canterlot, as "we don't know who's responsible" for the threat made against it.
* {{Foreshadowing}}:
** Shining Armor mentions early on that there was a threat made against Canterlot and he has been busy maintaining a shield. We also see his migraine reaction at doing it, which comes up later.
** Cadance's confusion when Twilight greets her for the first time.
** In Twilight's {{flashback}} we see that Cadance's magic aura is a light, silvery blue. In the present day, Princess Mi Amore Cadenza's aura is a SicklyGreenGlow.
** When the song "B.B.B.F.F." repeats at the end of the episode, it ends on a minor note rather than a major one. In musical terms, this is known as a UsefulNotes/DeceptiveCadence (the first time the song ends, it is on an UsefulNotes/AuthenticCadence).
** Also, [[http://www.equestriadaily.com/2012/03/updated-billboard-size-more-parody.html the billboard for the episode]], which shows Twilight looking very suspicious.
** While the ending of Part 1 bluntly reveals that Twilight's accusations of Cadance being evil were perfectly correct, only a split-second unnatural green flash in Cadance's eyes hints that she is not the real Cadance (nor even a pony) at all!
** When Pinkie Pie goes over the games with Cadance, she rolls two dice. A close look at the dice reveals that she rolls two ones, or Snake Eyes. This roll is usually associated in most games with bad luck, and snakes themselves are associated with deceit and betrayal.
* FreezeFrameBonus: [[http://static.tvtropes.org/pmwiki/pub/images/a653e25daf8bea166401a34de5e1c812.jpg The magic outline on Cadance's horn]] provides an extremely subtle bit of foreshadowing of the true nature of the villain.
* FunWithAcronyms: Twilight's B.B.B.F.F. and Applejack's countering P.F.F.[[note]]Pony Friend Forever[[/note]], both of which require explanation.
* FurryDenial: These obviously aren't real-life ponies, but we're still given this reminder. Cadance refers to Pinkie Pie's reception as a "six-year-old's birthday party." Horses, on average, live to be about 25-30 years old, so a six-year-old horse's birthday party would theoretically be more like a human Sweet Sixteen party... a far cry from what Pinkie's throwing.
* FurryReminder: Twilight snorts during her fit of rage towards the beginning.
* GettingCrapPastTheRadar: Twilight says that she is quite "ticked" at her brother for locking her out of the loop. Now had the rating been higher...
* GettingSmiliesPaintedOnYourSoul: One of Cadance's powers is the ability to spread love -- she uses it on an arguing couple, making them instantly drop the (rather dumb) thing they were fighting about. Portrayed as a positive thing.
* HeroicTeamRevolt: All of Twilight's friends leave her without saying a word, along with Shining Armor and Princess Celestia after she proclaims Cadence as evil right before Twilight's proclamations turn out to be right.
* HoistByHisOwnPetard: "Cadance" succeeds in keeping up her ruse even after Twilight calls her out. Even Twilight gives up her suspicions when all her friends turn their backs on her. But "Cadance" [[IdiotBall stupidly]] [[JustBetweenYouAndMe insists on gloating]] to Twilight that she was right all along afterwards, thus not only confirming Twilight's suspicions but allowing her to eventually spoil the evil plan.
* HopeSpot: During Twilight's MyGodWhatHaveIDone moment, Cadance appears and gently strokes her mane. Twilight tearfully says that she's sorry, and it seems like the two are going to reconcile... until Cadance pulls out her SlasherSmile and imprisons Twilight beneath the castle.
* IAmSong: "B.B.B.F.F." is a song that both describes what kind of pony Shining Armor is and also gives us more insight into Twilight's childhood.
* ImposterForgotOneDetail: Twilight first becomes suspicious of Cadance after she scoffs at their SecretHandshake and seemingly doesn't remember her. However, Twilight is only suspicious of Cadance being a jerk, ''then'' being "evil", rather than thinking that she's a fraud. Strangely, no one notices that Cadance isn't using the right color magic.
** Justified in that Twilight is the only one of the six who has met Cadance, and may not remember what color her magic was. That's if ponies can even see magic as well...
* InSeriesNickname:
** Twilight's brother calls her "Twily."
** Princess Mi Amore Cadenza is called Cadance by Twilight Sparkle and herself prefers to be called Cadance.
* InsultBackfire: The Princess says Pinkie Pie's reception would be great... if they were hosting a six-year-old's birthday! Pinkie beams and thanks her.
* IronicEcho: A nonverbal one; in Twilight's "BBBFF" song, she's shown absentmindedly crashing into Shining Armor, who scowls and then breaks into a grin. After Cadance runs out of the chapel crying, the same scenario happens, only this time Shining Armor is ''absolutely'' not smiling.
* {{Irony}}: Twilight says in her song that she and her brother "never had a single fight", but that's clearly no longer the case by the end of the episode.
* ItRunsInTheFamily: That breastplate that Shining Armor wants to wear for the wedding, which "was my favorite uncle's"? The six-pointed star on it features prominently in his and Twilight's cutie marks.
* ItsTheBestWhateverEver: Best wedding ever, as cited by Rainbow Dash and Pinkie Pie.
* LearnedFromTheNews: The episode opens with Twilight getting a public announcement and invitation to her brother's wedding. This is the first she's heard about her brother's engagement, so she's not amused.
-->'''Twilight:''' Yeah, ''great'' news. That I just got from a ''wedding invitation!'' Not from my brother, but from a piece of paper! Thanks a lot, Shining Armor. I mean, really, he couldn't tell me personally?
* {{Leitmotif}}: [[http://www.youtube.com/watch?v=pdsJgGfGHzU&t=0m12s Cadance has one]] that sounds like the ''Franchise/MyLittlePony'' theme with two extra notes inserted into each measure.
* LohengrinAndMendelssohn: Wagner's Bridal Chorus appears during the rehearsal.
* MadeOutToBeAJerkass: Poor Twilight goes too far to warn her friends that something was not right about Cadance, leading to her friends, and ''Celestia'', not to take her seriously. It turns out that Twilight was right all along, however.
* MeaningfulName:
** [[KnightInShiningArmor Shining Armor should be obvious.]]
** Cadance is a variation of not only a musical term, but a heraldic one -- ''[[http://en.wikipedia.org/wiki/Cadency cadency]]'' marks denote the birth order of sons or daughters of a given line. So her name connotes nobility, just like Blue Blood. It also has a connection to the military, as the classic boot camp SoundOff is properly called a Cadence.
*** Also, there's a meaning for the music experts: the song "B.B.B.F.F." was sung in the key [=Db=] minor. That means the root key was a [=Db=] major chord. Usually, an [=Ab=] major chord would lead into a [=Db=] major at the end of the song; this is called a V-I chord progression and is musically termed as an "Authentic Cadence". However, the song resolves on [=Bb=] minor, the relative minor of [=Db=], to give it a sadder tone at the end. When a chord progression seems to be heading to a root chord but instead ends on the relative minor, that is called a UsefulNotes/DeceptiveCadence. First documented [[http://ponibooru.413chan.net/post/view/171219 here]][[note]]Note: the image is somewhat incorrect in that it is ''B.B.B.F.F.'' that does that little trick, not ''This Day Aria''.[[/note]], and subsequently [[WordOfGod confirmed by Daniel Ingram.]]
* MoodWhiplash: Yep, [[RunningGag they do it again]] with the happy theme music at the end first half of a two-parter.
* MusicalSpoiler: B.B.B.F.F. has a subtle but major one which could only be spotted by people well-versed in musical theory. [[http://www.equestriadaily.com/2012/04/day-arias-hidden-meaning.html The song ends with a chord progression known as a Deceptive Cadence]]. Confirmed by [[WordOfGod Word of Composer]].
* MySisterIsOffLimits: Zigzagged trope. Twilight is outraged when she thinks her beloved BBBFF is marrying some random noble lady. Then she finds out that the bride is her surrogate big sister and thus the only pony she ''would'' approve of, but then she sees Cadence acting snotty and is back to square one but only because she thinks something is ''off'' with Cadence. Everyone else thinks Twilight is simply jealous. The viewer may be able to see in advance that Twilight is right, even if there is a ''little bit'' of this trope there too.
* MyGodWhatHaveIDone: Twilight after everyone walks out on her and she thinks she messed up. Unfortunately, this time she was ''right''.
* NiceHat: The Mane Six's hats -- both in the episode(s) and in promotional material (see, for example, the [[http://www.equestriadaily.com/2012/03/updated-billboard-size-more-parody.html billboard image]]).
* NonAnswer: Shining Armour is giving VERY evasive answers to Twilights (perfectly reasonable) questions about not being told about the wedding earlier, first evading the question by explaining about the threat against Canterlot, then distracts Twilight by asking her to be his best mare.
* OOCIsSeriousBusiness:
** Twilight initiates a song to talk about her brother. Since this is normally Pinkie Pie's thing, it shows how much Shinning Armor means to her.
** Celestia's looking worried [[Recap/MyLittlePonyFriendshipIsMagicS2E1TheReturnOfHarmonyPart1 again]]? We're doomed.
** Cadence brushing off the SecretHandshake is what sets off the alarm bells in Twilight's head.
* OutOfCharacterAlert: Twilight is devastated when Cadance refuses to do their secret hoof-shake when they were younger. She also notices she gives demands to everypony at will.
* PingPongNaivete: Spike gets all excited about organizing a bachelor party, but then asks what that is.
* PlotMandatedFriendshipFailure: The episode ends with every last one of Twilight Sparkle's friends -- and her ''mentor!'' -- on the outs with her. Luckily, the status quo is back to normal almost as soon as the second part begins.
* ProperlyParanoid: Twilight insists that the bride is ''evil'' and therefore shouldn't be allowed to marry her brother. Her behavior, however, makes everyone thinks she's jealous, but she turns out to be right.
%%* RealitySubtext: It has not been lost on the fandom that Twilight and Cadance's relationship has an awful lot in common with [[http://www.youtube.com/watch?feature=player_embedded&v=Nt2IVcrVkdc#! this particular story.]]
* TheReasonYouSuckSpeech: Shining Armor gives one to Twilight Sparkle after she accuses Princess Cadence of being evil, going as far as uninviting her from the wedding.
* RememberTheNewGuy: Twilights' FriendlessBackground was a key plot point in the pilot and came up again in later episodes. Now we learn that she had not only had a wonderful big brother but an ''equally'' wonderful surrogate big sister. Heavily lampshaded when her friends can't understand why she never mentioned either one of these supposedly close relationships to any of them.
* SeasonFinale: The two episodes in season 2.
* SecretHandshake: Twilight and Cadance have one.
-->''"Sunshine, sunshine, ladybugs awake! Clap your hooves and do a little shake!"''
* ShoutOut:
** On the [[http://www.equestriadaily.com/2012/03/updated-billboard-size-more-parody.html billboard]] image, Pinkie is wearing the [[http://www.rte.ie/ten/2011/0523/princessbeatrice.html same ridiculous hat that Princess Beatrice wore for the British Royal Wedding]]. All of the Mane cast save Applejack are wearing various hats photographed during the wedding, and even the flower in Applejack's hair resembles a hair decoration from the wedding.
** Shining Armor's outfit has the same colors and overall design as Prince William's wedding attire, and by extension the uniforms worn by BritishRoyalGuards.
* SiblingTeam: This is the first time we see Celestia and Luna tagteam.
-->'''Luna''': ''Rest, Sister. As always, I shall guard the night.''
* SicklyGreenGlow: Cadance's spells and Shining Armor's MindControlEyes. Astute viewers will notice that Cadance's spells weren't green in Twilight's flashback, providing some {{foreshadowing}} to the next episode's reveal.
* SingleTear: Twilight at the end of "BBBFF," lamenting what she sees as the growing distance between herself and her brother.
* SlasherSmile: Cadance gets one after summoning a circle of flames to drag Twilight away.
* SocietyOnEdgeEpisode: This two-parter involved a wedding {{plan}} coinciding with a need for increased security due to a mysterious threat against Canterlot. (Turned out it was connected to the wedding, namely due to the involvement of [[EmotionEater Chrysalis and the changelings]] in each.)
%%* StalkerWithoutACrush: Twilight herself towards Shining Armor and Princess Cadence.
* StealthPun:
** Applejack asks a downcast Twilight "Why the long face?", the punchline to that [[IncrediblyLamePun terrible old horse/barman joke]].
** Celestia takes care of the day, Luna takes care of the night, and Cadance takes care of the twilight.
* SuddenlyVoiced: Though very briefly, fan-favorites Minuette and Lyra Heartstrings speak for the first time outside of group scenes (in English[[note]]some of the foreign dubs voiced Lyra in earlier appearances[[/note]]), Minuette being voiced by Creator/CathyWeseluck.
* SurpriseCreepy: The ''CliffHanger''. While there were some creepy moments before it, Cadance suddenly donning a SlasherSmile and [[DraggedOffToHell summoning a circle of flames to drag Twilight down to who knows where]] is horrifying.
* ThemeTuneCameo: Very subtle, but the last "forever" Twilight sings in "BBBFF" (not the reprise) is sung in tune of the MyLittlePony theme.
* TrailersAlwaysSpoil: A [[http://www.youtube.com/watch?v=aaTBMSLF4LA clip]] uploaded by Hasbro's ''Franchise/MyLittlePony'' Website/YouTube channel says in its description "The Ponies make a cake for the Canterlot wedding, but the imposter Princess Cadance doesn't seem appreciative."
%%* TraitorShot:
* TrampledUnderfoot: When Cadance returns to the hall near the end, she steps on and shatters the Twilight figurine from the "graphics" for the DarkReprise of "[=BBBFF=]" as she approaches Twilight -- which Twilight seemed to be creating with her magic.
* UnusuallyUninterestingSight:
** Pinkie Pie sneezes confetti. The others seem to just shrug it off and nopony comments on it. Bonus points for coming right after Rarity's line: "Royal Weddings attract the strangest of ponies..."
** The defensive shield around Canterlot is clearly visible from Ponyville, and no-one seems worried about it. They only comment on it when they arrive, assuming it must be to do with the wedding.
* VillainBall: What chance would have Twilight -- despondent, regretful, not believed by anyone -- had to ruin the imminent invasion if the villain had left her alone instead of act against her?
* WalkingSpoiler: Cadance, due to the next episode's reveal that the one in this episode is an imposter.
* WeddingDay: Princess Celestia cordially invites you to the wedding of Princess Mi Amore Cadenza and..." ({{gasp}}) ''...[[RememberTheNewGuy my brother]]?!''
* WhatTheHellHero: Twilight gets a heavy one at the end of the episode by Shining Armor after she accuses Cadance of being evil, sending her out of the room crying, on bases he can easily counter. [[MyGodWhatHaveIDone Twilight reacts badly to this]], but it turns out she was right to accuse her.
* WhamLine:
-->'''Twilight:''' [[MyGodWhatHaveIDone I'm sorry...]]\\
'''Cadance:''' You '''will''' be.
** Twilight revealing that she has a brother; she never spoke of him before. The same goes for Princess Cadence.
* WorstWhateverEver: Twilight states that "Cadance is the absolutely worst bride-to-be... ever."
* WoundedGazelleGambit: Cadance breaks down in tears to alienate everypony else from Twilight.
* WrongGenreSavvy: Twilight easily picks up on the cues that Cadance is up to no good -- but the notion that her former favorite foal-sitter who suddenly acts as though they never met before might be an impostor never occurs to her until she finds the real Cadance in the next episode.
* YouHaveToBelieveMe: Twilight doesn't appear to do a good job of explaining why Cadence is evil to the rest of the wedding party (except for the spell she cast on Shining Armor, which was explained away) only because Cadence started crying, making Twilight look possessive and unstable in the eyes of her peers and alienate her from the group.
