In some versions of this fanfiction, Peeta could be a bit worried. Given the dangerous world they live in, he might be concerned about the safety of Katniss during the pregnancy and the future of the child. He could start making arrangements to ensure they have enough resources and protection, while also expressing his love and support for Katniss.
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.
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.
Katniss would probably be very protective at first. She has been through so much in the Hunger Games, and she wouldn't want her daughter to go through any hardships. Peeta, on the other hand, would likely be more empathetic and try to understand his daughter's feelings.
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.
She might be nervous. Katniss is used to being on her own and not having much family interaction. Meeting Peeta's family could be intimidating for her. She may be quiet at first, observing them carefully.
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.
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.
Their friends from District 12 would likely be overjoyed. The people there have seen so much hardship, and a new baby would be seen as a sign of hope. They would bring gifts, like hand - made baby clothes or food. Finnick, if he were still alive in the fanfiction, would be very supportive. He would offer his wisdom and share some of his own experiences if he had any related to parenting. He'd also be there to protect them from any Capitol interference.
Gale might initially feel a bit of jealousy and sadness, but he would ultimately be happy for them. He would probably offer his support in a more practical way, like helping with hunting to ensure they have enough food for the new family.
