Katniss might become more open and less guarded. With Peeta by her side, she could start to trust more easily. Peeta, on the other hand, might become more assertive in protecting Katniss and their new family. His gentle nature could still be there, but he'd have a newfound determination.
They would become more united as they have a new life to protect. Their focus would shift from just each other to their baby, and they would work together even more closely.
Common themes in Katniss and Peeta fanfictions include their emotional journey. In the books, they went through so much, and fanfics take that further. They might explore how Peeta deals with his hijacked mind and Katniss' guilt over the whole situation. Another theme is friendship - turned - love. Their relationship started as a strategic alliance in the Games, and fanfics often look at how that evolved into true love. And there's also the theme of sacrifice. Both of them were willing to sacrifice for each other in the books, and fanfics play around with different scenarios of sacrifice in their relationship.
Peeta and Katniss' love in the fanfiction is also influenced by their different personalities. Peeta is kind - hearted and more open with his emotions, while Katniss is more guarded. His openness gradually breaks down her walls. They learn to understand and accept each other's flaws. For instance, Katniss comes to appreciate Peeta's loyalty and self - sacrifice as they face the challenges together in the story.
They might have some disagreements, like how to raise the child. Katniss, who has grown up in a tough environment, might have different ideas compared to Peeta. But these differences would also help them understand each other better. They would communicate more and work through their issues together, making their relationship more solid.
Peeta would probably be very nurturing. He has a kind heart, so he'd be great at taking care of the baby's basic needs like feeding and changing diapers. Katniss, on the other hand, might be a bit more cautious. She's used to being in survival mode, so she'd be constantly on the lookout for any potential threats to the baby.
One possible reason could be that in this fanfiction, Peeta might have had a past experience with Katniss that made him lose his love for her. For example, if Katniss made a choice that deeply hurt Peeta, like choosing the Games over their relationship in a crucial moment. Another reason could be that the author wants to explore an alternative storyline where Peeta's feelings change due to external influences such as political pressure in the Capitol forcing him to distance himself from Katniss. Or perhaps, in this fanfiction, Peeta meets someone else who makes him realize that his feelings for Katniss were not as deep as he thought.
Another type could be a story about their adventures outside of District 12. They could be traveling to other districts to help with the reconstruction efforts. Along the way, they encounter different cultures and people, and their relationship evolves as they rely on each other in these new situations.
One challenge could be the lack of resources. Their world is often harsh, and getting enough food, medical supplies for the pregnancy and for the baby later would be difficult.
Prim is another character that shows up a lot. Fanfiction might focus on how Prim's relationship with Katniss affects Katniss's decisions during the games. For example, some stories could explore how Katniss's drive to protect Prim influences her actions towards Peeta, whether she sees Peeta as a threat or an ally in relation to Prim's safety.
