If it's someone new in the fanfiction, he could be a bit of an enigma at first. Maybe he's from another district. He might be initially scared but then step up. He'd have to deal with Katniss's strong personality and her fame from the Hunger Games. But over time, he'd grow into his role as a father - to - be and support Katniss through the pregnancy.
It will probably change her a great deal. In the original story, Katniss was mainly focused on survival and the fight against the Capitol. But with triplets on the way, her priorities will shift. She'll start to consider things like a safe place to raise her children, proper education for them. Her character will grow in terms of her emotional range as she experiences the joys and fears of motherhood.
Perhaps the father is a new character introduced in the fanfiction. A rebel from a far - off place who came to her district and they fell in love at first sight. He could be on a mission related to overthrowing the remaining oppressive forces in the post - Hunger Games world and their love and her pregnancy add a new dimension to his mission.
Well, it could also be Gale. Although Katniss has a more complex relationship with Peeta, her long - time friendship and some underlying feelings for Gale could potentially make him the father in a fanfic. It would add a whole new layer of drama to the story.
Peeta would be overjoyed and also very protective. He would constantly be by Katniss's side, making sure she has everything she needs. Gale might have mixed feelings. He still cares for Katniss deeply, and while he would be happy for her, there might also be a tinge of sadness that it's not him in that role with her.
While Peeta is the obvious choice, some fanfictions might explore the idea of Gale being the father. This could add a whole new layer of drama and conflict. Maybe there was a moment of passion between Katniss and Gale before she fully committed to Peeta, and this led to her pregnancy. However, this would be a more controversial take as it goes against the main narrative of Katniss's relationship with Peeta in the original series.
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.
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.
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.
Maybe Ron Weasley. Imagine a fanfiction where Ron, after getting married, has triplets. Given his humorous and sometimes clumsy nature, it would be really fun to see how he and his wife deal with three little ones. He could pass on his love for food and his loyalty to his children in a really endearing way.
