This is my theory about Lu Ten's death.?? It did not seem coinsidental.?? I think the death was set up by Ozai maybe to get the throne.?? I think he had connections with (DONT LOOK IF YOU DONT WANNA KNOW A FUTURE CHARACTER)
The king's advisor, Long Feng.?? He, I think set up the death of Lu Ten, and got away with it.?? This way, Iroh would lose, giving Ozai better chances.?? This goes against my suffering teaching Zuko theory, but still, it is from a different angle.
