Kay, I was overthinking things like usual, and I noticed something in the movie Frozen.
When the king is talking to the trolls, he says Elsa was born with her powers BUT when Elsa and Anna have their duet and Anna gets her heart frozen, Elsa sings "can't control the curse."
So . . . which one is it? Was Elsa born with her powers or cursed? OR was Elsa referring to some other curse, like maybe her family was cursed to never be able to control their emotions. (I don't know, best idea I could come up with.)
