The friends would all react differently. Effie would go all out in planning a grand baby shower, with Capitol - style decorations and gifts. Cinna, if he were still alive, would design the most beautiful maternity clothes for Katniss. Their friends from the districts would come together to build a safe and comfortable home for them, pooling their resources and skills to make sure Peeta and Katniss are ready for the new addition to their family.
Their friends would have a mix of reactions. Some, like Prim, would be overjoyed and start preparing for the baby right away. She'd knit little clothes and offer medical advice. Others, like Beetee, might use his technical skills to create some useful gadgets for the baby, like a self - warming crib. Johanna might seem indifferent at first, but then show her support in her own tough - love way, by teaching Katniss self - defense techniques even while pregnant.
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.
Peeta would be very supportive. He'd probably take on extra tasks to ease Katniss's burden. Katniss, on the other hand, might be initially a bit scared but would soon become a fierce protector of the unborn child. They'd rely on their survival skills to ensure they have enough resources for the baby.
Katniss might initially be a bit hesitant and worried, but she would quickly step up. She could use her skills to provide for the daughter during this time, like hunting to get extra food. Peeta would likely be more vocal about his support, talking to the daughter about his hopes and dreams for the future and how this new addition to the family can be a positive thing. He might also use his baking skills to make special treats for her. Overall, they would both be there for their daughter, drawing on their own relationship and the love they have for each other and their family.
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.
Gale might have a complex reaction. He has deep feelings for Katniss, so he could be a bit jealous at first. But being her friend, he would eventually come around and offer his support, perhaps by providing extra hunting resources for the soon - to - be family.
She might get angry. Katniss has a fiery side, and seeing Peeta with another girl could trigger that. She could give Peeta the cold shoulder and refuse to talk to him.
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.
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.
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.
