Y’know at first I was wondering why she didn’t just bend to defeat them. Firebending would’ve taken them out much faster. But instead, she took all these evasive maneuvers and instead of incapacitating them via injury, she wrapped them in canvas (?) and tied them up with rope, all without dealing them serious injury. Why? Because they’re her tribemates. Chances are, she’s known these people since she was small, and the fact that they think she’s betraying them when she’s just trying to help them is tearing her up inside.
Look at how she’s moving.
Spinning, circling steps.
Big circular arm movements.
Actually, I want to add on. She used Airbending. (Thank-you for catching that.) :) And Airbending in itself is what type of bending? Evasive. Avoid conflict, do not inflict unneeded damage, “push” don’t “shove,” etc. She doesn’t want to hurt these people. She just wants to stop them. Even if they hate her for what she’s doing, she just wants to stop them without harming them.
