After seeing Book 4 without the Red Lotus, even though the Red Lotus is explicitly said to be still out there, I'm not quite impressed because it looks as if they just threw the Red Lotus away. It would've made a great sub or sideplot where they must deal with recurring attacks from Red Lotus cells while fighting with Kuvira. All I can think of after seeing Book 4 is that Kuvira wiped out the Red Lotus, but I'm not convinced. I think if there was a sequel, it should be about a White Lotus agent who is tasked with weeding out Red Lotus cells. There could be a plot where the protagonist discovers that since the Red Lotus's formation, Red Lotus agents have been infiltrating the ranks of the worlds' governments and even within the ranks of the White Lotus, and it threatens to put them in disarray. Â For example, what if while Xai Bao left, he had followers secretly stay behind in the White Lotus to carry out his work and sabotage and corrupt the organization? Â
