Marco returns to St. Olga's for an honorary degree but is racked with guilt that he is lying about being a princess as well as a rule breaker.
Tropes:
- Answer Cut: At the party at the end, one princess asks where Princess Smooshy is. Cut to her being tied to a machine and having her emotions sucked out by Miss Heinous.
- Bittersweet Ending: The heroes successfully kick Miss Heinous out of the school and the princesses' faith in Marco is not broken by the reveal of him being a boy. However, Miss Heinous has captured Princess Smooshy to cut her losses and drained her emotions, becoming stronger in the process. And she is still at large, vowing revenge on "Princess Turdina"...
- The Bus Came Back:
- Princess Smooshy shows up again for a selfie with her camera phone.
- Miss Heinous crashes Marco's confession, along with Gemini and Rasticore's arm, now grown into a torso.
- Some princesses at St. Olga's were previously seen in "Club Snubbed", such as Princess Jaggs and Princess Spiderbite.
- Call-Back:
- When Star tells Marco there's something he should tell the princesses, he does his rallying cry of "It's not criminal to be an individual", from the rebellion at St. Olga's.
- Rasticore has regrown into a torso from the severed arm he was back in "Heinous".
- Comically Missing the Point: Miss Heinous declares that draining Princess Smooshy was barely worth it so she needs a much more powerful princess... and decides to go after Marco.
- Defiant Stone Throw: After Miss Heinous exposes Marco and gives a Breaking Speech, Star reignites everyone's spirits by throwing a water balloon.
- Does This Remind You of Anything?: Marco's revelation of his true gender is very reminiscent of a transgender person admitting their chosen gender, as opposed to the one they were born with.
- Emotion Eater: Turns out, this is what Miss Heinous has been trying to do to the princesses the whole time—steal their emotions and convert them into power.
- End of an Era: By this episode, Marco decides "Princess Turdina" has served her purpose; Marco intended for her to be a symbol of hope for the students to rally behind, and now that they have something to believe in, Marco decides it's time to officially retire her.
- Foreshadowing: Miss Heinous lets it slip during her speech that she needs the students, but only Star seems to hear. The end reveals that she's using them as a power source.
- Hated by All: Miss Heinous exposes Marco as a boy and tries to take over the school once more, but the students still universally hate her, while Marco at worst lied for a good cause.
- Icon of Rebellion: "Princess Turdina" has grown far beyond the man behind the wig and dress—she is an ideal. Marco decides to retire the persona and let her legacy live on in the students.
- I Can't Believe I'm Saying This: When Marco decides to take Pony Head's advice.Marco: I can't believe I'm saying this, but I'm going with Pony's advice.
- Inelegant Blubbering: Ponyhead does this at the end after Marco has "killed" Princess Turdina by revealing who he really is.
- Internal Reveal: The princesses learn Marco is not a princess and is a boy. They don't really mind. Heck, even Miss Heinous found out herself a while ago, which should've been obvious to her since her previous appearance.
- Liar Revealed: Subverted. Miss Heinous certainly thought that exposing Marco would cause the princesses to turn on him, but after getting over the initial shock, none of them really care and they remain on his side.
- Mood Whiplash: At the end, the princesses party again as one of them asks where Princess Smooshy is. Then it cuts to her in another dimension having her emotions drained by Miss Heinous, when the episode then ends.
- Red Eyes, Take Warning: Though not a supernatural example. Miss Heinous' eyes are red from presumably a massive lack of sleep.
- She Is the King: Fully gender flipped. Even though they now know he's a boy, and even though Marco is ready to retire Princess Turdina, the girls still give Marco the honorary title of Princess, crediting him for being the man behind an ideal they united behind.
- Shut Up, Hannibal!: As Heinous shouts at the princesses to be silent, Star hits her face with a water balloon. It promptly inspires them to charge at the headmistress.
- Villain Has a Point: Miss Heinous is not wrong when she says that the princesses' freedom turned the school into filth and that they have been lied to all along. Still it's much better than living under Heinous' rule. Of course, it all falls flat now that we know from the start she was feeding on their emotions to give herself power.
- We Will Meet Again: Miss Heinous is not done with Princess Turdina.Miss Heinous: I'm coming for you, Princess Marco Turdina!
- You Cannot Kill An Idea: Heinous clearly was going to make an example of "Princess Turdina", first by exposing "her" as a boy. By this point, Princess Turdina has become an ideal to the students, and all she'd be doing is bringing down the man who created her.
