My Little Pony: Friendship is Magic, Season 1

Princess Celestia:
Twilight Sparkle, my faithful student. I knew you could do it.

Twilight Sparkle:
But...you told me it was all an old pony tale.

Princess Celestia:
I told you that you needed to make some friends, nothing more. I saw the signs of Nightmare Moon's return, and I knew it was you who had the magic inside to defeat her. But you could not unleash it until you let true friendship into your heart.

[Twilight smiles at her friends.]

Princess Celestia:
Now if only another will as well.

[Reveal that Nightmare Moon has transformed back into Luna.]

Princess Celestia:
Princess Luna.

[Luna wakes up and gasps.]

Princess Celestia:
It has been a thousand years since I have seen you like this. Time to put our differences behind us. We were meant to rule together, little sister.

Twilight Sparkle/Rainbow Dash:
Sister?

Princess Celestia:
Will you accept my friendship?

[Long pause.]

Princess Luna:
I'm so sorry! I missed you so much, big sister.

Princess Celestia:
I've missed you too.
