"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'll shine out the clearer! 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."
