While the fleet re-provisions, "Ringle" sails to England under the steady and capable Lieutenant Harding, and returns with Sophie Aubrey, Christine Wood, her brother Edward Heatherleigh, Maturin's daughter Brigid, and Aubrey's twins Fanny and Charlotte, all of whom will sail with Aubrey and Maturin to South Africa. The three girls had not been getting along well, with the Aubrey twins jealous of any attention their mother gives to young Brigid, a concern to both fathers. Brigid is a natural sailor, having been on the "Ringle" at a very young age for her voyage to Spain and on the packet to return to England. The twins are seasick most of the way to the River Plate, whereas Brigid is at home, friends with the sailors and ready with answers to everything aboard ship. When they meet their father, the twins have shed the jealousy and begin to have a kinder connection with their cousin Brigid.
