Harmony's loyalty to her father will never die but will her friendship to Mal survive?

It's been six months since Harmony and her friends saved Auradon from Maleficent, everyone is happy except for 2 very important girls. When Mal and Harmony feel like they don't belong anymore they go back to the Isle of the lost.

Harmony is one of the 5 kids from Isle of the Lost. She is a total daddy's girl and would do anything for him even if she has to burn down Auradon. How will she and her friends handle being in a new place? How will she be without her father for the very first time?
