Hahaha! Love the way you avoid bad language in this blog!

In my opinion, Mal simply dyed her hair to blonde to look like an AK (Auradon Kid), and the purple tips represent that part that she is and will always be: Mal, daughter of Maleficent. Although she wants to forget it, but she can't because it's in her blood. Like the cast has said. D2 is about remembering where you come from and that hiding from it might not be as easy as you thought. The 4 VKs return to Isle of the Lost and find out that they cannot simply erase that villain part in them. The end will most likely be about them accepting who they are and their roots, and Auradon also learns to accept them.

Why purple again? (And with a fringe?) I think that since Mal returned to Isle of the Lost, she needed to return to her old self with purple hair, so she simply gave a makeover. I doubt that turning evil or becoming good changes her hair...
