Here is a brief summary:
Arronax is moved by Nemo's fervor as he speaks about the name Avenger. Arronax recognizes that Nemo's presence in the water was caused by "wrath, either hideous or glorious." For the time being, Arronax promises us that he will soon find the source of Nemo's rage, but he is distracted by a faint booming sound. He climbs to the platform, where Ned and Conseil are already standing, and looks out towards the ship Arronax in the distance, which he had seen earlier. The boys notice that it's a battleship, but they can't tell whose nation it belongs to because there isn't a flag visible anywhere.
