#the only more positive thing I can think of is that Midori's lavabending reminds me of the way Kat describes Vaatu

what if vaatu got midori instead??

Well.. "got" is kinda the wrong word here because honestly, I don't see Vaatu willingly fusing with a human in most circumstances, the exceptions being Adumbration by @katkastrofa – which barely counts since it was less fusing and more him being inside her already by virtue of growing inside Raava – and my Avatar Suiren AU, in which it's done on Vaatu's terms and Suiren doesn't remain fused to him a second longer than she has to, as much as she loves her little emo kite (may or may not be falling under the influence of both Kat and @shadelorde by implying that whatever the fuck Unalaq was doing with Vaatu was coerced and barely consensual since Unalaq was the one who had the most power in that sitiation. Do with that information what you will). And if he were to, I doubt Midori would be his first choice, nor would Midori herself wish to be the Avatar, Dark or otherwise

BUT if we operate under the assumption that it does somehow happen, Vaatu would have access to all of Midori's inner workings and I'm afraid that listening to her anxiety-ridden internal monologue of "I will forever be inferior to my gorgeous, powerful and capable sister. She will always be better than me, more beloved by everyone whose opinion matters, unaware of the inescapable shadow she casts. I'm doomed to remain the pathetic, useless little sister who can't even stand up for herself" will hit way, way too close to home and he'd yeet himself out of her within five minutes
