Plot hole: Breaking the spell should have been quite easy for Ella to accomplish. All she needed to do was have someone like Mandy or Areida command her to never follow another command again, and the spell would have been broken.

But, Slannen and his elf friends break her out and they crash the coronation. Ella reveals that Edgar was the one who killed Char's father and he was the one who plotted to kill Char. However, Edgar had poisoned the crown in a last-minute attempt to kill Char. But, he never wore the crown. Edgar, in a fit of anger, exclaims that he is the only one who can wear the crown and puts it on his head and topples over, but doesn't die. Ella and Char get married.
