Quote context

[...]

- We will come back.

- I wish I could see her just once more, to tell her all that's in my heart. She will never know what I really meant to say.

- She will remember your heart when men are fairy tales in books written by rabbits.

- Of all unicorns, she is the only one who knows what regret is and love.

- You are a true wizard now, as you always wished. Does it make you happy?

- Well, men don't always know when they're happy, but I think so. And you?

- I am a little afraid to go home. I have been mortal, and some part of me is mortal yet.

- I am no longer like the others, for no unicorn was ever born who could regret. But now I do. I regret.

- I am sorry, I have done you evil and I cannot undo it.

- No.

- Unicorns are in the world again.

- No sorrow will live in me as long as that joy - save one, and I thank you for that part too.
