Baggins has a healthy reaction to being confronted with endless roaming in the gloaming of a boundless, friendless forest. But quests, by their nature, seem to entail ‘getting to the other side’ of something, and the something is rarely easy.
The wizard’s blithe parting encouragement is hardly better: “Stick to the forest-track, keep your spirits up, hope for the best, and with a tremendous slice of luck you may come out one day…”
“Do we really have to go through?” groaned the hobbit. “Yes, you do!” said the wizard, “if you want to get to the other side. You must either go through or give up your quest. And I am not going to allow you to back out now, Mr Baggins.”
