- 555: The Sad Teen Hotline number is 555-0182.
- Adult Fear: Moon's motivation throughout the episode — and indeed through the whole Battle for Mewni arc — is to keep her only daughter away from harm.
- Both Sides Have a Point: Moon is right that Toffee is too powerful at the moment to face head-on, and they need to lay low; Star is right that they can't just hide away forever and they need to face the problem sooner or later.
- Call-Back: Eclipsa's silhouette was previously seen in one of Rhombulus' crystals in "Crystal Clear". This episode confirms that it really was her.
- Calling the Old Woman Out: When Star realizes that Moon's plan is to stay hidden, she calls her out for not acting to defend her kingdom and for treating her as a helpless child.
- Calling Your Attacks: When told not to use her wand, Star instead attacks the rat patrol with a stick and yells "Stick Blast!"
- Continuity Nod: Star uses the All-Seeing Eye Spell to observe Marco.
- Dog Got Sent to a Farm: Moon had apparently told Star that she sent her mother to live on a "grandma farm".
- Downer Beginning: Almost Played for Laughs as the episode opens up to Marco saddened over Star's mysterious disappearance...with her spying on him through her wand.
- Emo Teen: Both Star and Marco. As Star explains to her mother that two of the things the Marco taught her was "how to mope" and "self-pity"
- From Dress to Dressing: Moon rips a sleeve from Marco's hoodie, which Star is wearing as a keepsake, to bandage Star's wounds.
- Heroic BSoD: Marco is so distraught over Star's departure that he's taking to moping in the kitchen, in the dark, at 3 in the morning. He even refuses to let his parents take down the decorations from the end of school year party, so that if Star returns, it will be like she never even left.
- Leeroy Jenkins: Star keeps acting impulsively, trying to capture the rat scouts or going after Toffee herself, while Moon scolds her that they need to lay low.
- Never Say "Die": Moon avoids telling Star that Lekmet is really dead, unlike the other members of the High Commission who just had their life forces drained. She finally confesses near the end when Star insists on going after Toffee.
- She later blatantly says that Toffee killed her mother.
- Series Continuity Error: The party decorations weren't hanging above the Diazes stairway and in their kitchen in "Starcrushed". However, in the episode, there are decorations suddenly hanging out of nowhere with no explanation.
- Shout-Out: The carriage disintegrating until it disappears for lack of magic makes you think of Cinderella.
- Speaks Fluent Animal: Queen Moon is able to talk to the gator that guards the entrance to the sanctuary.
- Tempting Fate: After the warnicorn and carriage have disappeared thanks to the fritz, Queen Moon muses that they'll be fine as long as the magical path remains. Cue that blinking out.
- Tsundere: While watching Marco, Star irritably points out where she hid her favorite cereal, and shows annoyance at him being so overdramatic. But right after that, she calls him a "cute idiot".
- Wham Episode: This episode reveals that Toffee killed Moon's mother.
- Wham Line: Two, actually.Moon: I was never a cool warrior queen, Star. I was a happy-go-lucky girl like you. And then... Toffee and his monsters killed my mother.
Moon: Eclipsa's alive. And I made a deal with her...
- When Trees Attack: The High Commission gets caught in a living tree filled with skeletons. Its vines ensnare anyone that approaches. Queen Moon is wrapped up, but Star quickly yanks her free.
