Their relationship would likely become more intense. With a baby on the way, they'd have to rely on each other more. Gale might become more protective of Katniss, and Katniss would have to trust Gale in new ways.
I'm not entirely sure if there is a specific 'Katniss and Gale make love' fanfiction. Fanfiction is a vast world with countless stories. Some might focus on their friendship, while others might explore a romantic aspect. It's possible that there are some stories that take their relationship to that level, but you'd have to search through popular fanfiction platforms to know for sure.
There's also 'Gale's Hope in Katniss'. It explores how Gale holds on to his love for Katniss throughout all the chaos and hardships they face. It's a beautifully written fanfic that gives a different perspective on their relationship compared to what we see in the main series.
Another theme is the struggle with their different worldviews. Gale is more radical in his approach to the Capitol, while Katniss has her own way of dealing with things. Fanfictions often play with this contrast.
It would likely be a very emotional and complex story. Given their history and the difficult world they live in. It might start with the build - up of their long - standing relationship, the unspoken feelings they've had for each other. Then it could explore how such an intimate moment would change their dynamic, especially considering the political and social unrest in their world.
Some fanfictions focus on Gale and Katniss's relationship in a more domestic setting. For example, how they would have rebuilt District 12 together. They could be in charge of the reconstruction, making decisions about how to feed the people, and at the same time, dealing with their complex feelings for each other. Their love - hate relationship could be explored more deeply in this context as they face the challenges of rebuilding their home.
One plot idea could be that Gale and Katniss find out about the pregnancy during a time of relative peace in District 12. They then face the challenges of preparing for a new life while also dealing with the memories of the Hunger Games and the trauma they've endured. They might worry about how to protect their child from the potential threats that still lurk in Panem.
Archive of Our Own (AO3) is another great place. It has a well - organized tagging system. So, you can easily find 'Katniss x Gale' fanfics by searching for their names or relevant tags like 'The Hunger Games' and 'Katniss - Gale relationship'. There are some really high - quality works there.
One great Katniss and Gale fanfiction is 'The Unspoken Bond' which delves deeper into their pre - Hunger Games relationship. It shows how they supported each other in the Seam and how their bond was more than just friendship at times.
In the fanfiction, if Gale and Katniss had a baby, it could be a symbol of hope. Their relationship, which was always complex, would evolve in new ways. Gale, who has always been a fighter, would now be fighting for his family. Katniss, with her motherly instincts, would be teaching the baby about survival and the importance of love in a world that has seen so much destruction.
