AHHHHHH!!!! Okay, so I watched a couple theories about the new descendants trailer so here are my theories:
At first, I didn't believe it, but now I do. This teaser has finally convinced me that Mal's dad is Hades! In the trailer, if you stop it at the right time, there is a skull, that is blue. So, maybe Hades is warning Mal!
So, what are your theories based on the trailer?!? Tell me in the comments!!
