At the officer's dinner, James Fitzjames tells the diners consisting of John Franklin, Francis Crozier, Lt. Edward Little, Dr. MacDonald, Lt. John Irving, and Lt. George Hodgson about the time he was shot in China. Crozier sarcastically asks Fitzjames to recount the time he was assigned to guard bird guano. Franklin mentions that Reid noticed a patch of ice that doesn't appear to be summer break-up ice, but isn't concerned. Crozier has a meeting with Franklin and Fitzjames about David Young and Dr. MacDonald tells them Young has dark blood in his stool and he may have tuberculosis. Franklin suggests Dr. Stanley have a look at young and decides to have Young brought to his ship. Franklin gives a speech to the crew about how they will soon accomplish their journey. Six days later, both ships are stuck in the ice and the next morning they wake up to be surrounded by continuous ice.
