In a fanfiction, Zuko and Mai's relationship could be filled with lots of unspoken understanding. Zuko, with his intense and often brooding nature, would find solace in Mai's calm and collected demeanor. Mai, who has always been somewhat of an outsider in her own way, would see Zuko as someone who truly sees her. Their relationship might develop as they engage in activities together, such as training sessions or diplomatic meetings. Zuko could start to rely on Mai's sharp observations and insights, and Mai would find herself falling more in love with Zuko as she witnesses his growth and determination to make the Fire Nation a better place.
At first, Zuko might be hesitant to accept Hakoda's comfort. But as Hakoda continues to show kindness and understanding, Zuko could start to open up. They might develop a friendship based on mutual respect.
One plot idea could be that they initially struggle with the news. Zuko might be worried about how his role as a leader would be affected while Mai is dealing with the physical and emotional changes. They could face challenges from the Fire Nation's traditional views on pregnancy and family. Another idea is that they go on a journey to find a safe place for their child to be born, away from the political unrest in the Fire Nation.
Perhaps the fanfiction delves into the baby's unique abilities or characteristics. Since Zuko has a connection to the Fire Nation and Mai is a skilled fighter, the baby could inherit some extraordinary powers. It could show how they train the baby to control these powers while also giving it a normal childhood.
Zuko can be developed by exploring his role as a leader within the context of his marriage. He may struggle to balance his duties as Fire Lord with his time for Mai. This internal conflict can show his character's depth. He could also develop new bending techniques influenced by his love for Mai. As for Mai, she can develop by getting involved in more political matters, standing by Zuko's side and using her intelligence to influence decisions. She could also start to make more friends in the palace, which would change her somewhat solitary nature.
Their relationship would likely become more intimate and protective. Zuko would be more protective of Mai, constantly worried about her well - being during the pregnancy. Mai would probably become more dependent on Zuko for emotional support.
One possible plot could be that Zuko and Mai are initially shocked by the pregnancy. They then start to prepare for the baby's arrival. Zuko might be a bit overprotective, while Mai tries to keep her cool. Their friends could be excited or worried, and there could be challenges like dealing with the public's reaction as they are important figures. Maybe they face some threats to the unborn child which they have to overcome together.
Zuko could be developed by showing more of his vulnerability to Mai. He could open up about his past traumas, like his banishment and the search for his honor. This would make their relationship deeper as Mai could comfort him. For Mai, her character could be developed by showing her more passionate side towards Zuko. Maybe she could be the one to initiate some important conversations in their relationship.
Zuko's personality could be shown as more tender and caring than ever. He might be constantly worried about Mai's well - being and that of the baby. His sense of responsibility would be heightened. Mai, on the other hand, while still maintaining her dry sense of humor, would show a more vulnerable side. She may not be as openly emotional as Zuko but her actions, like making sure the nursery is safe, would show her love and care for the unborn child.
Maybe a plot where Mai is kidnapped by enemies of the Fire Nation who want to use her to get to Zuko. Zuko then embarks on a dangerous rescue mission. Along the way, he realizes just how much Mai means to him. Or a story where Zuko and Mai are forced into an arranged marriage by Fire Nation politics. At first, they resist, but as they spend more time together, they start to develop real feelings for each other that go beyond the political arrangement.
One plotline could be the challenges they face in the Fire Nation. Since Zuko is the Fire Lord, there might be political implications of his partner being pregnant. People might try to use the situation to their advantage or there could be concerns about the safety of the unborn child.
