Marji's parents protest every day. She tells them she loves the king because he was chosen by God, but her father, Eby, gives her a quick history lesson about how the father of the current Shah, named Reza, organized a coup to overthrow the emperor and set up a republic. With the support of the British, he succeeded. Marji's father then reveals that the emperor that Reza overthrew was Marji's maternal great-grandfather.

Marji's mother, Taji, picks up the story from there, describing how her father was placed in a water-filled cell for hours.
