Li Cheung is pedalling madly on the exercise bike. She is putting off her dinner until she is really hungry because fish paste makes her sick. She hears a loud racket and runs out into the other corridor, joining the other women. The lights flicker and she collides with Melissa. When the power comes back on, the women see a large blue box in the dining area. The Doctor tinkers with the transmitter, allowing his sonic screwdriver to access it remotely to release the anchors holding the pod to the ocean floor. The women will need to provide extra power on the exercise bikes.
