The kid is confused by the sight of Nemo and his men. He's sure that they're from the Halcyon group, but he can't figure out who they are. The kid wonders what the man with them is doing, and the man tells him to calm down. Nemo explains that the most important trait of a predator is its ability to evade its prey. For example, an octopus can change its color to match its surroundings. That's how one of Nemo's men will be able to catch Nemo.
