Star keeps seeing Glossaryck in her reflection.
- Back from the Dead: Glossaryck is brought back to life when Star deposits the remains of his spellbook in the healing temple.
- Came Back Wrong: The final scene, in which the resurrected Glossaryck speaks gibberish (specifically the phrase "Globgor"), suggests he hasn't been brought back as he was.
- Continuity Nod: Ever since she used the Dark Spell on Toffeenote , Queen Moon has been wearing longer gloves to hide her Volcanic Veins that now go up to her arms.
- Extreme Omni-Goat: Played with; the hors d'oeuvres at Lekmet's memorial service is tin cans, because that was his favorite food.
- Freeze-Frame Bonus: Viewers can tell early that Star has buried the spellbook piece in a pet cemetery by the tombstones, one of which is for Lil Chauncey.
- The Friend Nobody Likes: After Janna finishes talking to Star, it's revealed that she's with Marco and Jackie. Janna refuses to reveal who she was talking to. Marco then asks Jackie "Why do we even hang out with Janna?"
- Mirror Monster: Star sees Glossaryck in every reflective surface she looks into — a punch bowl, her bathroom mirror, a doorknob, a puddle, etc.
- Mirror Scare: Star is brushing her teeth before going to bed. She looks down to rinse her mouth, and when she looks up, Glossaryck is staring at her through the mirror.
- Noodle Incident: When told that Star is inside the punch bowl, Queen Moon's reaction is "Oh, No... Not Again!"
- Shout-Out: Janna explicitly chastises Star for burying the remains of the spellbook in a pet cemetery.
- Trailers Always Spoil: If you saw the promos, you knew Glossaryck wasn't going to stay dead.
- Unfinished Business: Janna thinks Glossaryck is haunting Star because he has unfinished business. Star deduces that he wants the piece of the destroyed spell book that she kept, so she goes to the healing temple from "Return to Mewni" and drops the piece into the well. This brings Glossaryck back, although still not fully functioning.
- Wham Episode: Glossaryck is brought back to life after his death, though he isn't quite himself.
