I really really wanna talk about this clip here, because I truly don't think people caught the subtlety of this scene's power.
Nine immediately going for the snarky comment, his usual demeanor to show off that he's cool, he's a loner, he doesn't need anyone.
However, when Sonic makes the correction, saying, "No, I-I mean, I always thought your extra tail was cool, but the metal ones? Man, you're amazing!", for a second you can see the genuine surprise on his face. He's so shocked that someone appreciates something that brought him so much misery that he literally does not know how to respond, responding with a nonchalant "Uhhh, sure..."
He's so surprised, but you can see the second he realizes he unmasked his uncaring nature, forcing himself back into his barricaded facade.
Maybe other people haven't caught it because it's so subtle, but as a person who had to barricade myself away like that,
i think sokka is the funniest example of a bisexual because he doesnt want to watch anyone else teach aang but when zuko does it hes like cmon guys lets go watch these stupid jerkbenders jerkbend so stupidly and they are shirtless! losers pfft 🙄🙄😳
