Storylines for Descendants 2?
If Descendants 2 needs a storyline; I think this is what could happen...
Mal, Evie, Jay and Carlos return for another year of Auradon Prep; but there are new villains' kids to attend. Una, Jordana, Freddie, Annabelle, Drusilla, Hayden, Ian, Helen and Gertrude are all invited to attend Auradon Prep by Mal. They meet Mal, Evie, Jay, Carlos, Audrey, Ben, Chad, Jane, Lonnie and Doug. They are also joined by fellow Auradonians, Melody, Kristanna, Adam, Virgil, Jordan, Ruby, Allie and Ellie.
Auradon Prep decides to put on the annual school production of Snow White; and eventually Audrey, Jane, Evie and Melody are all picked for a call back for Snow White; with Jay, Ben, George and Chad for the Prince. Eventually; in true mean-girl fashion, Audrey does everything to sabotage Melody's chances of playing Snow White; so she teams up with Una and Jordana to make sure she doesn't get the role.
