ok while katara marrying zuko and becoming the fire lady and moving to the fire nation is a cute headcanon and all i like to believe that if zutara had actually happened they would’ve argued for a while about where they would live? bc obviously zuko would have a duty to stay in his nation as the fire lord and he’d want katara to come with him, but she’d want to go back home and mend her broken village after the war
and so they’d get together and try long distance, taking turns visiting each other for a few years until one day, when zuko made a trip to the south pole, he’d ask katara to marry him, in the fire nation, to be his fire lady, and she’d say yes, but even after they were wed they’d still run into the same problems because katara would want to go home and zuko couldn’t just leave the throne??
so they’d agree to have children (luckily for zuko, their first child was a firebender, so he wouldn’t have to deal with more scrutiny for his decision to marry a waterbender) and once their children were old enough to understand, katara and zuko would remain married but decide to live separately. zuko would stay with his children in the palace until summer, when they’d visit the south pole and reunite with katara for a few weeks, and she’d go with them back to the fire nation for a few weeks more to spend time with them before leaving again, and that’d be their system for years until their oldest child was sixteen, and zuko decided he no longer wanted to be fire lord, and he’d abdicate from the throne, and he and katara would retire to a remote village in the earth kingdom, in the middle of both of their homes for the rest of their days
