S6E10 · Sleep, Dearie Sleep

Complete story — includes the ending

As the Queen's 80th birthday nears, her advisers ask to begin planning Operation London Bridge, the plans for her state funeral. Charles asks the Queen for permission to marry Camilla, but she is reluctant to give it. After consulting with the bishops, and William and Harry, she grants Charles and Camilla permission. Elizabeth selects the lament " Sleep, Dearie, Sleep " to be played at her funeral after the royal bagpiper suggests it. William, Kate and Harry attend a costume party where Harry is photographed wearing a Nazi uniform with a swastika armband, and he is condemned by the media. A rift develops between William and Harry, though they later reconcile. Elizabeth sees her middle-aged self encouraging her to abdicate, while a vision of her younger self later encourages her to continue. Charles and Camilla marry, and the Queen delivers a speech at the blessing at St George's Chapel. Philip commends Elizabeth on her decision not to abdicate. The Queen, alone in the chapel, sees visions of her coffin and her younger selves as "Sleep, Dearie, Sleep" plays, before leaving through the West Door, disappearing into white light.
