Diagoro is such a brave little guy. Goes looking for his father with no hesitation, just pure instinct.
It was nice to see Itto and Retsudō working together to solve the flood problem. Even when both men want to kill each other, they're still honorable men. They end setting off the explosives and that's when Diagoro gets a hint toward where his father is. Little chap was ready to swim there, but luckily some guy on a boat finds him and is taking him there.
