I DON'T OWN THE SHOW, MOVIE, OR SONG!

Ok so this song takes place in between Captive and Wicked Always Wins.

Storyline:
After a month, Zhan Tiri succeeds in convincing Rapunzel that friends no longer care about her and are still mad at her for the pain she's caused them. Though it's not enough to complete the transformation process to darkness. Until Elsa and Anna come to visit, everyone is impressed by Elsa's ice powers and how well she can control them now. This makes Rapunzel jealous, since Elsa has more control of her powers and she doesn't and that she's taking her friends away.
Rapunzel finally breaks and decides to get revenge. She goes into Varian's room to take the moonstone(so she can overpower the guards and overthrow her parents to become the queen), Varian witnesses all of this and goes to warn Eugene, Cassandra, Adira, Lance, Elsa, Anna, and Kristoff that Rapunzel is in danger with dark magic.
If you're wondering what Rapunzel is doing at the end, she's channeling the moonstone's magic so she can properly use it for her plan.
As for what happens afterwards, Rapunzel has her parents trapped in their rooms(like she was in the tower), keeps Elsa, Anna, and Kristoff under castle arrest. Adira luckily escapes. Rapunzel still sees companionship in Varian though, since to her he's suffered just as much as her. She eventually gives the moonstone back to him, with the promise to never use it against her.

Anyways, that's it. Hope you enjoy!
