zuko and katara are the kind of best friends who never shut up. they are constantly talking over each other at the same time and their voices get louder and louder the longer it goes on. despite the chaos, they each fully absorb what the other is saying. they would actually have a harder time understanding each other if there wasn’t so much screaming.
zuko and toph can basically communicate telepathically. zuko will come into toph’s room after a tough visit with azula and they’ll just sit there for a while. she’ll flick him in the arm at the exact right moment and he’ll feel better. or she’ll stomp into his room to cool off after a fight with katara, and they won’t say anything, but his waves of loving energy will bring her back down to reality.
zuko and aang always talk in cryptic references to adventures they’ve had. aang will nudge zuko and say something like “hey. remember that guy with two belts?” and they’ll burst into giggles and refuse to explain the joke to anyone else. (you had to be there.) or they’ll be working on some new piece of policy and just fully start speaking in code. zuko will mumble something like “don’t forget bosco” and aang will derail the whole meeting to add more restrictions against exotic pet breeding.
zuko and sokka talk intensely and honestly and with a lot of poetry. it took sokka by surprise to discover just how often zuko will quote a poem rather than describe his own feelings, but after a while he got into it and now they both do it, nerds that they are.
oh and zuko and suki? their letters to each other are all pictograms. they’ve planned entire vacations this way without exchanging a single word. suki will be like “👾🥬🦟🦟🍒🗺👙❓" and zuko will be like “🚢‼”
