What is Maleficent and the Dragon were somehow connected? Aurora and Mulan are certainly connected. We know Aurora was a target of Maleficent, and Mulan could have known the Dragon. There could be a backstory there.
And the Dragon and Mulan are from the same realm as the Yaogui, who was really Philip after being cursed by Maleficent, there’s another connection. What if Tamara uses her magic-taker Taser on Maleficent?
And maybe that is how they are getting all of their information. Through Maleficent.
