Rise of the Guardians2012

[Pitch and his nightmares have raided Tooth's palace, stealing the teeth and kidnapping all but one of her fairies]

Jack:
I'm sorry about the fairies.

Tooth:
You should have seen them. They put up such a fight...

Jack:
Why would Pitch take the teeth?

Tooth:
It's not the teeth he wanted. It's the memories inside them.

Jack:
What do you mean?

Tooth:
That's why we collect the teeth, Jack. They hold the most important memories of childhood. [leads Jack to a mural depicting her duties as the Tooth Fairy] My fairies and I watch over them, and when someone needs to remember what's important, we help them. We had everyone's here. [touches Jack's shoulder] Yours, too.

Jack:
My memories?

Tooth:
From when you were young; before you became Jack Frost.

Jack:
But... I wasn't anyone before I was Jack Frost.

Tooth:
(puzzled) Well, of course you were. We were all someone before we were chosen.

Jack:
(shocked) What? That night at the pond, I just assumed... So you're saying, I had a life before that, with... with a home, and... and a family?

Tooth:
(surprised) You really don't remember?
