If the moon can give water bending, logic saysshe can take it away. But if that's impossible, perhaps the Kingdom could do what Iroh suggested and hold the Moon Spirit, and possibly the Ocean Spirit hostage. The Tribe surrenders, and the Moon and Ocean are unharmed. And since the only way La will take action is if Tui dies, he won't do anything. Plus, since Tui and Yue are now the same being, Arnook will stand down for the sake of his daughter.
