Trivia / Twilight Sparkle and the Crystal Heart Spell

• Accidentally-Correct Writing: Trixe's villainous role in this book seems to ignore that she has reconciled with Twilight by this point in the series. Come Trixe's next appearance in the show, she's not as over her rivalry with Twilight as previously implied. Coincidentally (or not), this was after the book's writer became one of the show's writers.
• Ascended Fanon:
  • Hoops' name. It was also the first time Berryshine's other name "Berry Punch" was used officially, but her Adaptation Name Change was not identified yet.
  • Twilight calls Cadance her pegasister-in-law. Cadance also learned to rule "with love and tolerance".
• Fandom Nod:
  • Several background ponies are given mention, including Berry Punch and a certain grey Pegasus who asks for muffins.
  • The phrase "Love and Tolerance" is mentioned as well.
  • It's also mentioned in the book that Twilight used to build "book forts" as a filly. She apparently amasses one at the climax as the amulet is corrupting her by amplifying her negative feelings.
• What Could Have Been: Originally, Queen Chrysalis would have been the villain. This was vetoed due to it interfering with the first arc of the comic, so it was changed to Trixie and Gilda.
