And I figure Mitchell’s character is the “middle sister” who we’ll see as a child, then also in her 30s, at which point the older sister’s dead so the middle one becomes Queen and yadda, yadda, yadda, suffering, angst, kingdom of isolation, evil Snow Queen is made, and there’s your lesson of what might have become of Elsa if Anna had died.
Let me guess, Anna and Elsa’s mother would be Mitchell’s other sister? Guess to explain if Elsa’s snow powers are genetic.
