Cassandra returns to the Spire to steal the Mind Trap from Calliope. Calliope sends a letter to Rapunzel for help and she and Eugene set out by hot air balloon. They pass through the frozen tundra of Krestin Lock where they are shot down and reunite with Calliope who claims to have escaped. They battle their way through the fish like natives, but Princess Rapunzel rescues a couple as they leave. They arrive at the Spire where "Calliope" asks for the key to unlock the chest containing the Mind Trap, but Rapunzel sees through the ruse; Cassandra reveals herself and "Calliope" is Zhan Tiri in disguise.
They fight over the Mind-Trap Stone, but when Zhan Tiri threatens Calliope again, an overly compassionate Princess Rapunzel gives the Mind Trap to Cassandra. Before leaving the Spire, the Enchanted Girl reveals herself as Zhan Tiri to Rapunzel and tells her that she has been using Cassandra and threatens Corona yet again with an inevitable eclipse. Cassandra returns to her tower and activates the Mind Trap; brainwashing Hector, Adira and Quirin.

- Zhan Tiri: "I believe Cassandra promised us a proper introduction. But she failed to deliver, didn't she? Frankly, I'm surprised you haven't guessed who I am; seeing as we have already met. In a way. You see, over the centuries, I've taken the form of whatever suits my needs- A warlock, a demon, even a blizzard."
- Princess Rapunzel: "You're...Zhan Tiri. But that doesn't make any sense. Cass knows how evil Zhan Tiri is. Why would she team up-"
- Zhan Tiri: "Cassandra knows only what I want her to know. I'm playing her, Rapunzel. She has no idea, but she is under my complete control. Prepare yourself, Sundrop. An eclipse is coming. And when it does, Corona will become nothing more than dust."
- It is revealed that all members of the Brotherhood had actually sworn loyalty to whichever human becomes host to the mighty Moonstone via the blue Mind-Trap Stone, with the crest of the Dark Kingdom on it.
- The Enchanted Girl is revealed to be one of the many forms that Zhan Tiri herself can shapeshift into.
- The way Eugene tells a badger to get off him is similar to the way Cassandra told Ruddiger to get off her in Cassandra's Revenge and it is also similar to the way Varian told Pascal to get off him in Rapunzel's Return.
- Lance, Angry and Red and Maximus did not appear in this episode.
- The way Cassandra tells Rapunzel that she does not want to hurt Calliope in this this episode is similar to the way Cassandra told the abducted Varian that she does not want to hurt him in Cassandra's Revenge.
- The way Rapunzel complies by giving Cassandra the key to open the chest to the mind trap then Calliope won't be harmed in this episode is similar to the way Rapunzel complied to help Varian free his dad from the amber in Secret of the Sun Drop because she doesn't want him to harm her mom.
- It is also similar to the way Varian complies by telling Cassandra the third incantation in Cassandra's Revenge but he doesn't know what will happen to him if he doesn't comply.
