Final answer:
As the relationship between Reuben and Roxanna isn't explicitly described in the provided excerpts, giving a detailed account of how Reuben's feelings change over the course of the novel isn't possible without the relevant sections of the text. Typically, characters experience growth from indifference to affection through bonding and shared experiences, but specific details are necessary for a conclusive analysis.
Step-by-step explanation:
It appears that Reuben's feelings for Roxanna undergo significant changes throughout the novel. Based on the provided text, which seems to come from a mix of different stories, we may infer that the narrative deals with themes of love, passion, strength, and morality. However, the question specifically mentions Reuben and Roxanna, whose story isn't clearly represented in the excerpts. Therefore, to accurately trace the evolution of Reuben's emotions towards Roxanna, it would be necessary to have the relevant sections of text that directly reflect their relationship within the novel's context.
Without the specific narrative of Reuben and Roxanna, we could draw general conclusions based on literary analysis of similar plotlines. In such plotlines, characters often experience a shift from initial indifference or disdain towards a deep affection and realization of love for the other character. Feelings might develop through events that create a strong bond or through personal growth and self-reflection. A character might start to see admirable qualities in the other or deepen their connection based on shared experiences. Nevertheless, these are generic developments, and without the exact references to Reuben and Roxanna's interactions, it is not possible to provide a detailed analysis of the change in Reuben's feelings toward Roxanna in the novel.
