can you imagine how the whole energybending scene must have looked to Sokka and Suki
Sokka: “ohmygod, I think aang’s losing!”
Suki: “you dont know that, maybe red is aang’s color”
Sokka: “you think the motherfucker who was planning to genocide the entire world with fire has a *blue aura*??”
Toph: “what the FUCK are you guys TALKING about”
this is really funny but unfortunately they would only see aang with his hands on ozais face and chest. we got to see the same technique from a different perspective in korra
But i posit to you that this can be funnier because sokka and suki would see aang just hold his hands on ozai for a few moments and it would look super anticlimactic from their perspective
