As the story progressed, it put Bilbo to the test of his wit.
The Dwarves soon find out that he can be very helpful, despite their reluctance to his aid. Although Bilbo is a full-fledged adult, certain scenarios force him to ‘grow up’ in a sense. He has to face his fears, like in chapter 8, where he had to fight of the spiders to save the group. The more often that there are riveting scenes, the more Bilbo familiarizes himself with his fight-or-flight instincts. He owned up to his mistake in Chapter two for bothering the trolls and endangering the whole group. By chapters 9 and 11 and so on, he suppresses those uneasy feelings he gets, and goes on to be an integral addition to this
expedition. The person Bilbo was before and at the end of the quest are completely contrasting characters. In the beginning, he was complacent with his life, thinking that he really was set. After the quest, he had a new outlook on life and in the process, lost his well-to-do reputation. Chapter nineteen states that Bilbo did not care much for his reputation in the end. He was more content with the accomplishments and experiences he endured. The meaning of the journey was a means of regaining pride and surfacing a new facet in Bilbo’s life.
