Romance can also be a theme, not just in the sense of a romantic relationship between Peeta and Finnick, but also how their relationships with other characters are affected by their own experiences. Some fan fictions might explore Peeta's love for Katniss and how Finnick's own relationships are intertwined with the events, creating complex emotional webs that add depth to the story.
The trauma they've both endured is a big part of it. Fan fictions usually deal with how they cope with their pasts. For example, in many stories, they find solace in each other. Also, the power dynamics within the Capitol and how they resist it together can be a central element. It shows their strength as characters and their will to fight against oppression. In addition, their individual skills, like Johanna's combat abilities and Finnick's charisma, are often used to drive the plot forward in interesting ways.
A moment that stands out is when they have to survive in a harsh environment together. Finnick uses his knowledge of the sea and fishing to get food, while Katniss scouts for danger and protects their camp. Their mutual trust and reliance on each other during this time really show the strength of their relationship in the fan fiction.
