He could meet Frodo. Frodo is a very important hobbit, and Aragorn might have an interesting conversation with him about the Ring and their different experiences.
Aragorn may develop a more complex relationship with power. As the Ringbearer, he has to constantly battle the allure of the Ring's power. This could lead to him becoming more humble as he realizes how easily power can corrupt, even someone as strong - willed as him. He might also grow in his understanding of the smaller races, like the hobbits, who he now has a new - found respect for since he is in a position similar to Frodo's.
I'm not sure if there is such a specific fanfic. Fanfics cover a wide range of themes and scenarios, but this particular one seems rather unorthodox. It might exist in some corner of the vast fanfic universe, but it's not a common or widely known concept.
A common theme is Aragorn's leadership. Many fanfics explore how he leads Gondor and the other kingdoms, like in 'The Leadership of Aragorn' where it shows his decision - making process. Another theme is his relationship with Arwen, as seen in 'Aragorn and Arwen: Love in Middle - earth'. And his ranger past often comes up, like in 'Aragorn: Return to the Ranger's Life' which focuses on his skills as a ranger.
One great fanfic is 'The Bond Beyond Rivendell'. It beautifully depicts Aragorn and Legolas' friendship as they face numerous challenges in Middle - earth together. Their unwavering loyalty to each other is shown through various battles and adventures. It also delves into their personal conversations, revealing a deep understanding and respect between them.
I really like 'Aragorn and Eowyn: Paths Not Taken'. This fanfic takes a different turn on their story. It imagines a scenario where Aragorn and Eowyn have more time to get to know each other on a personal level. It's beautifully written, with great descriptions of their emotions and the world around them.
One common theme is love that overcomes all. Their love has to face many challenges like Aragorn's dangerous quests and Arwen's long - lived elven nature, but in fanfic, it often triumphs. For example, in many stories, their love endures even when they are separated for long periods.
Another theme is the exploration of their different paths. Aragorn is on his journey to become king, and Eowyn is trying to find her place in a male - dominated world. Fanfics often play with how these different paths could cross more meaningfully.
A good Aragorn and Eowyn fanfic should have a deep understanding of their characters. Their personalities, values, and the roles they play in the original story are crucial. For example, Aragorn's leadership and Eowyn's courage should be accurately portrayed.
Maybe he would be amazed by the simple and peaceful life in the Shire. He could meet the hobbits, share stories around the fireplace, and learn about their unique culture.
