Nemo asks Aronnax if he'd like to visit a pearl fishing ground. Of course, Aronnax says yes.
It's too early for pearl diving, Nemo says, so they'll have the place to themselves. The pearl divers, poor Indians who dive from small boats, won't show up for a while.
Nemo and Aronnax discuss the primitive, pitiable conditions these divers toil under.
Though Nemo warns Aronnax that the waters are shark-infested, he doesn't tell Ned and Conseil. Aronnax explains how pearls work, slipping in a few comments about sharks along the way. Eventually, he tells Ned the grim news in the most casual way possible.
To Aronnax's surprise, both Ned and Conseil are cool with this adventure anyway.
