A plotline could also involve Katara and Zuko being the only survivors of a shipwreck. They have to rely on each other to survive on a deserted island. During this time, they learn about each other's skills. Zuko's fire - making skills help them keep warm and cook food, while Katara's water - bending helps them find fresh water. This mutual dependence leads to a deep friendship.
One great story could be 'The Journey of Zuko and Katara' which delves deep into how they grow as individuals and together. It shows Zuko learning to fully embrace his new role and Katara becoming more understanding of different cultures. Another one might be 'Zuko and Katara: Allies to Lovers' where their friendship gradually turns into something more as they face various challenges side by side.
Well, perhaps Katara blames Zuko for something that went wrong in their attempts to bring peace to the world. She might think he made a decision that cost them dearly. Her disappointment and anger could be so intense that she lashes out at him verbally. Zuko, who has been trying hard to redeem himself, is deeply hurt by her accusations and starts to cry. It could also be that Katara misunderstands Zuko's intentions in a situation. Say he was trying to protect her but it looked like he was being controlling, and when she confronts him about it, he can't handle the thought of her seeing him in such a negative light and cries.
One possible plotline could be that they initially struggle with the news due to the political implications in their world. Maybe their respective nations have different views on their relationship, and they have to fight for acceptance. Another could be that they focus on preparing for the baby, with Katara teaching Zuko about water tribe traditions related to childbirth. And a third plotline might involve an external threat that targets Katara because of her pregnancy, seeing it as a way to manipulate Zuko or disrupt the peace between their peoples.
Some fanfictions explore their role in rebuilding the world after the war. Zuko and Katara could be working together to restore balance between the nations. This kind of fanfiction often shows their leadership skills and how they complement each other.
In some fanfictions, a plotline could be that they discover their feelings during a mission in a far - off land. Away from the prying eyes of their comrades, they start to see each other in a new light. Maybe they are forced to rely on each other more than usual, and through shared hardships, their love blossoms. Another aspect could be how they deal with jealousy. For instance, if Katara has admirers from her own tribe, Zuko might struggle with feelings of jealousy and have to figure out how to handle it without revealing their relationship. And vice versa if Zuko has Fire Nation girls showing interest in him.
One possible adventure could be exploring ancient ruins. These ruins might hold secrets about the origins of bending or some long - lost artifacts. They would have to solve puzzles and overcome traps to uncover the mysteries within.
One plotline could be that Zuko and Katara have been secretly in love for a while. They finally confess their feelings and decide to start a life together. Then the pregnancy becomes a new chapter in their relationship, with them having to deal with the reactions of their friends and families. Some might be happy, while others might be skeptical at first.
A really interesting plotline is when they both discover new powers or abilities that are related to their connection. Maybe Zuko discovers a new way of using his firebending that is linked to Katara's waterbending, or vice versa. This often leads to a lot of training sessions together, which in turn strengthen their bond and also lead to some really cool action scenes in the fanfics.
One possible plot development could be Katara initially resisting the marriage wholeheartedly. She might try to escape or find a way to nullify the forced union. This could lead to a lot of tension between her and Zuko, as he may be more accepting of the situation due to political or family reasons.
One possible plotline could be an alternate universe where Zuko and Azula were raised differently. Maybe they were closer as siblings and a kiss could be a sign of their deep bond. Another could be a story where Azula has a change of heart after her fall from grace and she and Zuko share a moment of reconciliation that involves a kiss as a symbol of forgiveness.
