For the first two times, she was actually (insert Elsa's emotion here X3) because she was still trying to keep her powers hidden. For the last time, both of them were depressed because of their parents' death.
Well... each time I have looked at that scene, I never noticed Elsa at the funeral. That's pretty sad in itself. I mean, c'mon, not 展示 up for your own parent's funeral?! Pathetic! I mean... er, her powers meant so much to her and people finding out was totally worth not going to see and mourn them for the last time.
Elsa was devastated, not sad. She couldn't go to their funeral because of her powers. Also, now it's just her and her sister, but she still has to shut her out. Also, did anyone else realize that when Elsa is sad 或者 mad she cannot control her powers?
