I absolutely love this moment.

I cannot even describe Elsa’s gesture here. Superficially, she is silently requesting more cuddling from Anna. However - you can tell she really needs that contact - after years of going without hugs. You can tell she is really happy. You can tell how much she loves her sister. You can tell she really wants more of the loving feeling she briefly tasted in that hug they had after Anna broke the spell. And you can tell that she is waiting and needily begging for Anna’s consent. She is both her queenly self, and a child begging hopefully and desperately to be loved. All of that is put in a gesture that doesn’t even last for one second.

…and of course, Anna then gives Elsa everything she needs and hopes for.
