Philip returns from war, bringing crowds of slaves with him. He also marries a woman from Thrace to seal an alliance, causing mad jealousy in Olympias. In retaliation, Olympias appears on stage in a celebratory play, something which is allowed her as a priestess of Dionysos, god of theatre, but is still considered wildly shocking since only men are supposed to appear on stage. In the gossiping crowd afterward, Alexander slashes the leg of a man who he hears insulting his mother. To atone for attacking someone without warning, Alexander sacrifices to Zeus, and believes that the god speaks directly to him during the rite.
