Isabel enters the science fair with her friends but ignores Elena's advice about teamwork and tries to do everything herself. Meanwhile, Carla, still disguised as Rita, is advised to seek out the weakest link in Elena's chain of friends — Mateo.
Tropes in this episode include:
- An Aesop: Teamwork is important.
- Continuity Nod:
- The last time Isabel was in the Science Fair was in "Model Sister".
- Carla is still an undercover spy in the castle from the previous episode, with everyone still fooled by her disguise.
- Head Desk: Carla does it when Matteo is summoned away to help Elena immediately, ruining her plans.
- Near-Villain Victory: Carla once again makes it into the treasury with Mateo, but a guard arrives to tell Elena has summoned him for help with Isabel's project, thus she fails to take the tiara again.
- Paper-Thin Disguise: Downplayed. Naomi did not immediately recognize Victor, but she knew his lady disguise was not a very good one.
- Sequel Hook: Carla returns to Shuriki, her plans ruined again, and reveals the reversal potion which they plan to use to restore Fiero.
- Shout-Out: Victor, disguised as an old lady, tries to give "Rita" an apple, referencing when the Evil Queen disguised herself as an Old Hag to give Snow White a poisoned apple.
