Gus and Call have lived and worked together for over 30 years when the novel begins. What keeps them together despite their constant impatience with one another? What is the source of their mutual loyalty?

Despite his many accolades, the respect of his men, and his reputation, Call is a disappointment to himself. Where does his self-loathing come from? Why does Gus say that Call can’t be happy unless he is suffering more than anyone else?

The fact that Call is Newt’s father is the most poorly kept secret in Lonesome Dove. Near the story’s conclusion, Call appears to come close to revealing the truth, but doesn’t. Why can’t Call acknowledge Newt as his son? What effect does this have on Newt and his outlook on family?
