Boromir might develop a sense of wonder. Earth has so many different cultures, landscapes, and technologies. This exposure could make him less rigid in his thinking. He could start to question the way things were in Middle - earth and consider new ways of living. He might see how different races interact here in a more peaceful way compared to the tensions in his own world and strive to bring that back to Middle - earth if he ever returns.
Boromir visiting Earth in fan fiction would be quite an adventure. He'd likely be drawn to places of power or authority, thinking they were like the halls of Gondor. He could end up in a military base, for example, and try to assert his warrior status. Or he might wander into a museum and think the exhibits were some sort of ancient artifacts from a long - lost civilization. He'd probably have a hard time adjusting to the modern concept of time, being used to the more natural rhythms of Middle - earth.
One common theme is the clash of cultures. Boromir is from Gondor and Catelyn is from the North in Westeros. Their different upbringings and values often lead to interesting interactions and conflicts in fan fictions.
A common theme could be the clash of different worlds. Boromir is from Middle - earth with its medieval - like setting and magic, while Caitlyn is from a more modern - ish, steampunk - inspired world. So, stories might explore how they adapt to each other's worlds. Another theme could be their combined skills in combat or problem - solving.
One great 'boromir catelyn fan fiction' is 'The Unlikely Bond'. It explores a scenario where Boromir and Catelyn meet during a diplomatic mission. In this fic, their different worlds collide, leading to an interesting exchange of ideas and a budding friendship.
There are many platforms where you can find Boromir and Caitlyn fan fiction. Archive of Our Own (AO3) is a great place to start. Just search for 'Boromir Caitlyn' in their search bar, and you'll likely find a variety of stories.

One idea could be that Boromir is on a quest in Wally World. He thinks it's a strange new land full of unknown magic. Caitlyn, who is already familiar with Wally World, becomes his guide. Along the way, they encounter a group of mischievous kids who are causing trouble in the store. Boromir tries to use his combat skills to stop them in a non - violent way, while Caitlyn uses her charm to talk some sense into them.
Well, it's a rather unique combination. It might be that very few people have thought to create such a fan fiction. However, if you were to write it yourself, you could imagine Boromir and Caitlyn having an adventure in a Walmart - like setting. Maybe they are on a quest and Walmart is some sort of strange magical place in this fan fiction world.
Well, it could be an adventure story. Boromir, a character from 'Lord of the Rings', and Caitlyn from another realm (assuming) meet in Wally World. Maybe they team up to solve a mystery there. Boromir's warrior skills and Caitlyn's unique abilities could combine to face challenges like a strange creature that has been causing chaos in Wally World.
Well, it could be that she recognizes a kindred spirit in Boromir and wants to offer him a place of refuge. Or perhaps she has a sense of duty to help someone in need.
