Dear Anna,

Sometimes I wonder, if I were to let myself use these powers, what wonderful things I could do… What are my limits? How far do they reach?

I can never know the answer.

As soon as those thoughts come to mind, I remember the way the snow struck you, and your still form, lying in the room. I remember the panic on Mother and father's faces, and our race to see the trolls.

I remember what they said.

It could have been so much worse Anna, but it was already so bad.

When I lie awake at night, wishing that it had never happened, I remember their words, and I change my mind. If it had never happened, my powers would have continued to grow, and maybe – just maybe – something far worse would have happened.

I can't let anything else happen to you – I just can't!

Your sister who misses you

Elsa
