We were so close. We can be like that again.
Friendly reminder that during this scene Elsa probably wasn’t just sitting by the door the whole time. She didn’t sit there until she heard her sister knock, and then she sat right in front of the door to be as close to her as she could. And the snowflakes suspended in the air? Those are for the grief of her parents, but the snow/ice all around the spot she’s sitting? That’s the grief she has over not being able to open the door to her sister.
