You're obviously trying to prove me wrong, I can tell. On the other hand, I can actually do accurate research more efficiently than someone who vandalizes a section of a page in order to "prove" their claims.
The fandom says that "Anga spots a patch of Tuliza past a nearby sea. The team arrives at the sea, only to find that the water is extremely salty. Makini suggests that Kion relax in the water, and he relents. Once in the water, he calms and begins to float on his back."
The Wikipedia article states "Taking Makini's advice, Kion decides to soak in the water to soothe his scar and becomes relaxed."
Now it should be obvious that "calm" and "relaxed" are synonyms. As paraphrased:
"The team arrives at the sea, only to find that the water is extremely salty, and Makini suggests that Kion relax in the water. Taking Makini's advice, Kion decides to soak himself in the water, and once in the water, he calms and begins to float on his back."
The 2 last sentences in the paraphrase here signify that Kion did not actually sleep. Obviously, I am not forging this AT ALL; even real Lion Guard haters would agree with me on this, you excluded for obvious reasons.
