In the post - war fanfiction, their relationship could evolve into a romantic one. They've had a strong bond for a long time. As they work side by side, Aang might finally be able to fully express his feelings for Katara. They could start a family together, with their relationship based on love, trust, and a shared vision for the future of the four nations.
Their relationship could deepen as they share in the joys and sorrows of rebuilding the world. They've been through a lot during the war, and now they can truly rely on each other. They might become even closer friends at first, with a mutual respect for each other's abilities growing stronger.
Their relationship often develops through shared adventures. They face many challenges together, which makes them rely on each other more and more, leading to deeper feelings.
In some cases, the anger could be a catalyst for a more romantic development. Aang expressing his strong emotions might make Katara realize the depth of his feelings for her. Or it could be the other way around, Katara's reaction to his anger could make Aang see her in a new light, leading to a shift in their relationship dynamic towards a more romantic one.
In modern fanfiction, their relationship might develop slowly as they navigate modern - day life. For instance, they could start as friends who meet at a coffee shop regularly. As they share their dreams and fears, they realize they have deeper feelings for each other.
Their relationship would likely deepen. After the war, they have more time to focus on each other. They'd probably have more romantic moments, like taking walks on the beach or having quiet dinners together. Aang would be more open about his feelings, and Katara would be more affectionate towards him.
Katara could be heartbroken. She might initially be in denial, not believing that Aang has actually left. Then she could become angry, feeling betrayed by Aang's sudden departure.
Well, a common theme in fanfiction is their romantic adventures. Fanfic writers love to imagine Aang and Katara going on secret dates to beautiful, hidden places. These could be secluded islands or magical caves. Their relationship in fanfiction can also be a bit more complex than in the original series. There could be misunderstandings due to their different upbringings. Aang being the last Airbender with a more carefree nature at times, and Katara being a strong - willed Water Tribe girl.
It developed gradually. At first, they were just friends on an adventure. But as time passed, Aang's feelings for Katara grew deeper.
It could also be that Katara was being overly critical of Aang's progress in learning new skills. Aang might feel frustrated and angry if Katara is constantly pointing out his flaws instead of being more encouraging, especially if he's already trying his best.
One possible storyline could be them traveling the world together to help rebuild the nations. They could use Aang's Avatar powers and Katara's waterbending skills to bring water to drought - stricken areas or help with construction using earthbending - like techniques. Another could be them settling down in the Southern Water Tribe and starting a family while also teaching the next generation about the importance of the four nations' unity.
Aang might go into a deep state of depression. He has always been an emotional character, and having his heart broken by Katara, someone he loves deeply, could send him into a downward spiral. He might isolate himself from his friends and stop practicing his bending for a while.
