"katara has ALWAYS been in love with zuko!!"
Katara: *literally threatens to kill Zuko in season 3 episode 12*

"katara and aang came out of nowhere!!"
Season 1 Episode 14: the Fortuneteller

"katara chose bald 13 year old baby aang over sexy ass 17 year old zuko!"
Katara is 14 and they're all children

If you wanna ship water and fire so bad Sokka has never threatened to Kill Zuko & he was most willing to befriend Zuko besides Aang since he showed up to help them defeat the firelord. Also Sokka is 16 and significantly closer to Zuko's age

And you know
Katara & Zuko & Aang could theoretically make a good throuple when they're all adults in the future but not as kids ! Whew
