↳[5/10] Scenes: "I'm the one that needs to go after her."
The one thing I don’t like about the scene is that Anna did not do anything wrong, but she’s blaming herself for Elsa’s problems.
But that’s the interesting thing — Anna didn’t know what set her off; Anna had the memory of what had shut Elsa away from her for all that time wiped from her head by the trolls, to keep her safe. Her whole life, she’d wondered why her sister shut her out, she laments this in ‘Do You Want to Build a Snowman’ and, being alone, she’s probably imagined that she’d done something to Elsa. Why else would her sister deliberately avoid her?
When Elsa finally comes out and they get to spend this day together, they have a disagreement that ends in Elsa running away. Since she doesn’t understand Elsa’s turmoil about her ice powers, Anna blames herself for setting her off.
Anna has been isolated from everyone her whole life — in the same way Elsa has — but where Elsa knows why she’s isolated (she’s done it to herself out of fear), Anna does not (she’s been unfairly punished). To cope, she’s probably spent her life telling herself she MUST have done something wrong and this becomes a mindset, one that’s hard to break. So when Elsa runs away, she blames herself because it’s what she’s been conditioned to do.
