Look at Idunn here.

Look at her concern in the first image, her longing to reach out and comfort her desperate child. She loves Elsa so deeply. No doubt she has laughed with her often, seen her smiling and carefree.

Look at her eyes widen in the next few moments, look at the shock and horror. It is not horror because she sees Elsa as monstrous, but because it shatters Idunn’s heart that Elsa thinks of herself this way. Her little baby, her sweet child… will not let her parents touch her… Because Elsa loves them too deeply and does not want to hurt them.

Look at the way something breaks in the queen, look at her struggle to hold back tears.

In a mere couple of seconds, we can see such grief in Idunn… such guilt… She never wanted this to happen to her daughter, never meant for this to happen to her daughter… her poor little child… now so lost and afraid.
