You work with the fire lord but he left u to die.

while trying to find the Avatar you got shot in the stomach. Turns out The fire lord shot you and didn't realise it was you..he laughs and lefts

after a while Sokka walks by and finds u.

Sokka: "Shit, shit, shit! You're okay, you're okay!" he speaks in a panic and shakey tone of voice, his hands were shaking and he was breathing heavily
