the avatar seemingly was destined to fall in love with the southern water tribe leader’s family. yue —> sokka, aang —> katara.

think of it. every previous avatar we’ve seen in a relationship wound up with someone in the same elemental group. aang was a unique case since his entire culture was wiped out and he wanted to repopulate it a century out of his proper time. so his soulmate moved an element forward in the ordering (air, water, earth, fire). on a deeper level, in moving a century forward via the iceberg, aang still had the family the avatar in this generation was supposed to have; with the water tribe. “Sokka and I, we’re your family now.”

this ripple effect even makes sense of korra. the first two elements aang masters are the easiest for him, as air and water are complimentary. but korra, a water tribe native, is awful with airbending. she’s great at earthbending, she’s great as a firebender, and she’s good at waterbending because that’s what she was born into. but she’s awful at air. she’s bad with air like aang was bad with earth. because air and earth are opposites. and korra is an earthbender avatar in a water tribewoman’s body. everything makes sense now with this context

going absolutely crazy on this: if aang hadn’t trapped himself in the iceberg and learned all four elements in a year (like we know he can) but when he was meant to be trained, then he defeated firelord sozin, meaning the technology resulting from the conflict was able to progress beyond weapons of war, it’s possible that the technological advancement of korra’s time would’ve been around in yue’s time. meaning that the equalist movement would’ve naturally been on the rise. so, of course, the universe would want the avatar to see the complexity in this situation. which would explain why yue’s southern water tribe soulmate is a nonbender interested in technology. with sokka.... just like korra’s is. in asami
