Katniss copes in multiple ways. She has to be strong for herself, Peeta, and the unborn child. Emotionally, she might bottle up some of her feelings at first, but as time goes on, she realizes she needs to let them out. She could start writing in a journal about her experiences, fears, and hopes. Physically, she takes care of herself as best as she can in the difficult situation, eating whatever nutritious food she can find and getting enough rest when possible. Socially, she tries to keep a small circle of people around her who can support her, and she also tries to slowly re - introduce Peeta to those who care about him in a way that won't trigger his hijacked state.
Katniss would likely be determined to get Peeta back to his normal self. So, instead of just retaliating, she would focus on finding a cure or a way to reverse the hijacking. She might isolate herself with Peeta in a safe place to try and break through to him, using her own memories and emotions to reach the real Peeta hidden inside the hijacked version.
Perhaps the story could focus on how Katniss and Peeta's relationship changes because of these two major events. With Katniss pregnant, she has new fears and hopes. And Peeta, being hijacked, is not the same person she once knew. Their journey could be about rediscovering each other. Katniss might use the idea of their future family as a motivation to bring Peeta back to his old self, while also preparing for the new life that's about to come.
Well, in such fanfictions, the pregnancy can be a symbol of hope. After all the trauma they've been through in the Hunger Games, having a baby is like a new start. It might also lead to some interesting character developments. For example, Peeta's protective nature could become even more pronounced, and Katniss might struggle with her role as a soon - to - be mother while still being the strong Mockingjay.
In this fanfiction, their pregnancy could be a source of great stress as well. Given their past traumas and the dangerous world they live in, they would be constantly worried about protecting their unborn child. For example, they might fear that the Capitol could use their baby as a pawn in their power games. So they would have to take extra precautions to keep their pregnancy a secret for as long as possible.
This kiss could potentially be a turning point. It might bring back memories for Peeta or make Katniss more determined to help him recover. It all depends on how the author weaves 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.
Perhaps Peeta, while hijacked, is made to target Katniss's friends and family as well. This would put Katniss in a difficult position of having to protect them from Peeta, while also trying to save him. It could lead to some very tense and emotional scenes. Also, Katniss might try to get help from other rebels who have experience with dealing with Capitol - inflicted mental torture to try and reverse what has been done to Peeta.
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.
Well, it might be about how their relationship evolves during the pregnancy. Peeta could be extremely protective of Katniss, and they might have to rely on each other more than ever. They could also be visited by old friends from the Games, who offer their support and advice. And perhaps there are some health scares during the pregnancy that make them realize how precious their family - to - be is.
