Answer:
Towards the conclusion of "The Brief Wondrous Life of Oscar Wao," Oscar is depicted as a mournful character who has ultimately discovered some internal serenity. Throughout the book, Oscar is portrayed as an awkward, overweight, and nerdy young individual who grapples with finding affection and approval. His peers and potential romantic partners habitually turn him down, and his aspirations to become a writer seem like mere whimsical desires.
Nevertheless, in the latter section of the story, Oscar eventually finds fondness with a woman known as Ana. Their romance is brief, but it becomes evident that Oscar has encountered the kind of closeness and intimacy that he has yearned for extensively. It seems as if their tale of love has transcended into an epic narrative that is passed down to future generations.
Furthermore, the book concludes with the implication that Oscar may have ultimately found redemption or deliverance. Even though he is deserted and succumbing to his demise in the Dominican Republic, he appears to be at ease with himself and his destiny. His final sentiments depict a sense of resignation and acceptance, indicating that he has finally found harmony and resolution. In summary, Oscar is depicted as a sorrowful but relatable character who has discovered a modicum of love and serenity towards the end of the novel.
