Balin

"Yes, I’m afraid. I fear for you. A sickness lies upon that treasure hoard, a sickness that drove your grandfather mad."

- Balin to Thorin

Balin was one of the main protagonists of The Hobbit''. ''He is one of Thorin's oldest friends and companions, and closest friends growing up (other than Dwalin). He was very fond of his brother, Dwalin, shown when they both laugh when they see each other's presence and bonk heads together. During the course of the journey, Balin forms a friendship with the company's burglar, Bilbo Baggins, and often teaches the hobbit about Dwarf culture.

Despite believing the quest will fail, Balin continues to follow Thorin's lead, claiming that they were with him to the very end. At the end of the film series, Balin upheld what he told Thorin in Bilbo's home so long ago and followed him out on the battle for one last time.
