* AccidentalAesop: If you're feeling jealous about another friend's success or good fortune, ''talk about it''. Even if your friend can't compromise and give you those good fortunes (like Fluttershy did), talking may lessen the jealous feelings you have.
* AccidentalInnuendo: Rarity: "''I'm'' the one who should be mobbed by strangers wherever I go!"
* EnsembleDarkhorse: Photo Finish seems to be quite popular in the fandom.
* IdiotPlot: An interpretation of the plot could be that Pinkie Pie, who has trouble when people don't explain why they're not talking to her or telling her the truth, prevents Twilight from mediating a discussion between Rarity and Fluttershy as to why they're not talking to each other or telling each other the truth.
* ParanoiaFuel: Pinkie Pie stalking Twilight Sparkle to make sure she doesn't break her "Pinkie Promise". She hides in a bowl of sponges and even takes the place of Twilight's reflection in a mirror!
* TheScrappy: Pinkie Pie is this for the episode, due to her constant popping up to keep Twilight from confessing on what Fluttershy and Rarity think about each other, [[NiceJobBreakingItHero which would have solved the episode's problems]]. And even at the very end, after Rarity and Fluttershy tell the truth to each other, she's off the hook on their secrets, but blurts out the "Spike loves Rarity" secret...despite the fact that everypony knows about it, and Pinkie's disappointed at that.
** And apparently the staff picked up on this as [[Recap/MyLittlePonyFriendshipIsMagicS5E20TheOneWherePinkiePieKnows she later gets a taste of her own medicine]], even getting the hammy '''FOREVER''' turned on her.
* {{Squick}}: Fluttershy's magically forced nose-picking scene in the second fashion show. The ponies (even Derpy) in the audiences were really displeased.
