“Frodo: I can't
do this, Sam.
Sam: I know. It's all wrong. By rights we shouldn't even
be here. But we are. It's like in the great stories, Mr.
Frodo. The ones that really mattered. Full of darkness and
danger, they were. And sometimes you didn't want to know the
end. Because how could the end be happy? How could the world go
back to the way it was when so much bad had happened? But in the
end, it's only a passing thing, this shadow. Even darkness
must pass. A new day will come. And when the sun shines it will
shine out the clearer. Those were the stories that stayed with
you. That meant something, even if you were too small to
understand why. But I think, Mr. Frodo, I do understand. I know
now. Folk in those stories had lots of chances of turning back,
only they didn't. They kept going. Because they were holding
on to something.
Frodo: What are we holding onto, Sam?
Sam: That there's some good in this world, Mr. Frodo... and
it's worth fighting for.”
