Descendants 2! Descendants left us on a cliffhanger with Mal saying "You didn't think this was the the end of story did you."

My 2nd idea is Ben start sending another group of another villan's kids after another and turning good‚ but maybe get this one group that give them trouble.
Now my 3rd idea is that Ben marrying Mal and mal learning how to be queen
