The secret of Elsa's snow

I need to know

Anna: don't you ever wanna know how you got your powers?
Elsa: oh, that's right, am I a monster? I've hurt my sister I've hurt guards I've hurt everyone!
Anna, you should take my place.
Anna: Wait, I can't be Queen!!! You are
Elsa: I need to know how, why.
Jack: it's because the moon chose you.
Elsa: Jack..... What's your story, how do you control your emotions, your actions? Why doesn't any one get hurt?
Jack: My story... My sister and I were playing in a Frozen pond, the ice cracked, I fell and... It happened.
I had powers but, no one could see me, no one believed in me, I made snow days for them I had fun but, I was
Invisible. I just had to except it. But soon, the moon chose me as a guardian and there I was, making kids smile.
Anna: Elsa if you could control your powers, no one would call you glove girl!
Elsa: Anna, you heard me today and you heard me last time. I belong here. The kingdom
Won't last. It just won't with me leading them.
