Ariel now enters, unseen by the group on stage, and puts all of them to sleep, except for Sebastian and Antonio. Left awake, Antonio and Sebastian devise a plot in which Sebastian will seize his brother's crown, much as Antonio had years earlier seized his brother's title and property. Although Sebastian has some concerns of conscience, Antonio dismisses such worries and urges action while everyone is asleep. Sebastian needs little convincing, and with Antonio, the two draw their swords and advance on the sleeping king and his party.
At this moment, Ariel takes action. He awakens Gonzalo in time to prevent the murders. Antonio and Sebastian quickly concoct a story to explain their drawn swords, warning of great noise, as if from bulls or lions. Alonso is easily convinced of his brother's sincerity, and the scene ends with the royal party leaving the stage in search of Ferdinand.
