Hold on a sec. If Koh is lynched today, Sokka cannot die (unless FF have that killing role and a recruit after it). So then we just Jet-hunt and it's all good. Derp.
TA has nothing to fear from Zuko executing them since they'll win with FN/FF falling. FF should out Jet so that they don't get executed and screwed of a win.
-vote Koh
I'm pretty sure that's the most optimal plan moving on from here. Has noone else realize that?
Keep in mind game won't end til we lynch Iroh, once TA and FF are dead. And Zuko can easily find him through a failed execution (also the lolz on how much that breaks canon).
