The development in fanfiction often depends on the writer's interpretation. For instance, some fanfics focus on Peeta's post - Games recovery and how Katniss's care for him during this time deepens their relationship. This could make Gale feel left out, intensifying the triangle. Other times, it could be Gale who takes some heroic action that makes Katniss re - evaluate her feelings for him. Meanwhile, Peeta's own insecurities about his relationship with Katniss, given Gale's presence, can also be a major factor in the development. Fanfiction gives a lot of room to explore how each character's actions and emotions can shift the dynamics of this love triangle.
In fanfiction, the development of the Katniss - Peeta - Gale love triangle can start from different points. Some might begin with Katniss's pre - Games relationship with Gale, showing how their bond was formed through hunting and surviving in District 12. Then, the Games enter the picture, and Peeta comes into her life in a very dramatic way. As the story progresses, Peeta's love for Katniss becomes more and more obvious, while Gale is waiting for her back home. Fanfic writers might make Katniss struggle with her feelings as she experiences different situations with both of them. For example, a shared moment of vulnerability with Peeta during the Games could make her question her feelings for Gale.
