One has to wonder, how did Mowgli know Dr. Plumford would be capable of healing Baloo's bullet wound? Because he treated Mowgli's bullet wound from when Wilkins grazed him earlier.
Each of Boone and his men die a somewhat Karmic Death that reflects either their own follies or the follies of men.
Harley has always looked down on Mowgli as a "little brown brother", only to drown in brown quicksand.
Tabaqui reflects the human folly of human wrath and violence. He tries to kill Mowgli with a giant boulder, but Mowgli throws the man's balance off and he falls to his death.
Buldeo represents the human folly of vindictiveness and goes after Mowgli on the technicality that Wilkins shot his leg mistaking him for "the little man-cub". Ironically, it's Mowgli who was wronged when Buldeo let the former's father be wrongfully devoured by Shere Khan. But Mowgli doesn't even know, or care for that matter.
Last but not least, Boone falls victim to the folly of Greed, where he's weighed down by his bag of treasure (and eaten by Kaa).
For a moment, it seems a case of Fridge Logic that instead of eating Boone and his men, Bagheera chose to chew the ropes tying Mowgli to the tree. He could've eaten them and then they could've escaped. But remember why Mowgli didn't bring Kitty along: "It's safer with these men and their guns." Mowgli must've somehow told Bagheera to spare these men, knowing they somewhat kept Shere-Khan at bay.
How long had Tabaqui been following Mowgli before they reached the waterfall?
Harley rants at Colonel Briden for not paying him what he's owed. On one hand, it would be easy to assume he's just being greedy. On the other hand, bear in mind that in the Victorian era, he's probably looked down upon by other British officers for his Scottish background. So assuming he's not lying, it's quite possible (and quite sobering) that Harley has a reason to be sore at Colonel Briden.
