The four fractured communities finally come together at the Kingdom for a long-awaited trade fair and to sign a mutual protection charter.
Alpha sneaks into the fair disguised in the scalp and clothes of a murdered woman. She later shows Daryl a massive ocean of walkers that the Whisperers control.
To mark her territory and punish the communities for crossing her lines, Alpha abducts and murders 10 survivors, placing their reanimated heads on wooden spikes.
