sokka and katara have probably never spent more than a week apart from each other, both growing up in the south pole and having literally traveled everywhere together…
…until after the war.
the gaang probably got swept up in fixing the relations between the nations, helping with rebuilding in cities and towns, and just fixing the entire world way past what should have been expected of them, and so when they inevitably went their separate ways, how well do you think sokka and katara coped with that?
do you ever think that katara might sometimes turn around to try and crack a joke about her brother only to realize that sokka isn’t there to laugh with her? did she sometimes forget that the first person she looks to for support simply isn’t there to have her back anymore?
do you ever think about how sokka, maybe searching for a chance to make fun of his little sister, realizes she isn’t there to bicker with him anymore? or how maybe after so many years of trying his hardest to protect her, sokka can’t quite sleep because he isn’t able to know for certain that katara is okay at that very moment?
and when they do end up meeting back up again, did either of them cry after not having seen each other in person for weeks or even months? or were they too stubborn to admit that they missed one another?
how long did it take for these siblings to settle in with the fact that things were never going to be the same as it was before they left the southern water tribe the day that they found aang?
