- Streisand Effect: How the Children of Nightmare attempt to keep their summoning ritual a secret.eycor0: Never mind the fact that a bunch of pegasi in cloaks pushing clouds around over the Everfree forest would probably draw more attention than just leaving it be.
- Stupid Evil: Spell Nexus
- Sucky School: Ponyville Elementary.
- Take That
- Whenever the plot is mentioned.
- "Rarity!" Twilight half shouted.Ezn: And half whispered, creating an interesting vocal effect.

- In chapter twelve, the part where Twilight apologizes to Nightmare Moon.Wild Trotter: This is gonna hurt, isn't it?
Crazy56U: Ooooooh, yeah. (pulls out tissues)
- When Rarity gets an iiiiiddddddeeeaaaa~!
- Time Travel Tense Trouble: Lampshaded whenever the unedited tenses get mixed up.Nuke.Equestria: Twilight's time travel spell malfunctioned.

Alcoremortis: Personally, I'm a fan of, "There's no turning back now" and talking about the wife and kids in a war movie.
- What the Hell, Hero?
- Pretty much any time Twilight does something foolish.
- And when Spike is bribed into not revealing Nyx to Celestia.
- When it's revealed that Celestia planned on killing Nyx if it turned out she's Nightmare Moon.Celestia: She is a product of a spell, and well be dealt with as such. She will be dispelled and the lingering energy purified.
Crazy56U: So... in other words, you're going to kill a filly to confirm your paranoid suspicions... yeah, um, lady? WHAT IN HOLY HELL IS WRONG WITH YOU?!?
- Not to mention this bit (albeit played for laughs):
- Worth It: Vimbert feels this way concerning Celestia's plan to kill Nyx if it turns out she's Nightmare Moon. Crazy56U begs to differ.

Fanfic / Past Sins MST
Past Sins is one of the most popular fanfics in the My Little Pony: Friendship Is Magic fanbase. Months after completing the story, its author Pen Stroke decided to give various writers from the /fic/ board on Ponychan a chance to riff the original, previously unseen and unrevised version of the story. Readers from the Equestria Daily fansite were also recruited to add riffs of their own. The result is an MST, which can be found online.
