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’ll shine out the clearer. […] 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.
- What are we holding onto, Sam ?
- That there’s some good in the world, Mr. Frodo, and it’s worth fighting for.
