The narrator and Asuka are in the middle of rebuilding their shelter when a large stingray appears on the horizon. The narrator is shocked to see the stingray's tail, which has a barb on it, and he is afraid that the stingray has bitten him. He tries to swim to shore with the stingray, but the animal bites him instead. Asuka tries to get her ears to pop, but she is unable to do so because of the pain in her ears. They are almost out of the shelter, and they have not had time to collect their food. When Asuka notices that her ears are hurting underwater, she has to pinch her nose to relieve the pain.
