What happens
Caliban persuades the drunken Stephano and Trinculo to help him murder Prospero and take the island. Caliban describes Prospero's weaknesses—his afternoon sleep, his books, his daughter Miranda—and promises to show them the island's riches in exchange. Ariel, invisible, repeatedly calls Caliban a liar, sowing discord. The three men gather stolen clothes and prepare to act, though Ariel's music and tricks distract them from their purpose.
Why it matters
This scene reveals Caliban's desperation and cunning. After twelve years of servitude, he seizes what he believes is his chance at freedom. His offer to Stephano is transactional—information and loyalty in exchange for rulership—but his description of Miranda exposes his conflicted desires. He has learned enough language and strategy from Prospero to mount a real threat, yet he remains powerless without allies. The irony cuts deep: Caliban's path to freedom depends on serving a drunkard, substituting one master for another. His plan is pragmatic but also reveals how thoroughly colonization has warped his thinking—he can imagine freedom only through domination and hierarchy.
Ariel's invisible interventions complicate the scene's moral landscape. By sowing discord among the conspirators, calling Caliban a liar, and causing Stephano to beat Trinculo, Ariel prevents the plot from advancing. Yet Ariel does this under Prospero's command, meaning the torment of these would-be assassins serves Prospero's will, not justice. The scene raises uncomfortable questions: Is Prospero justified in preventing Caliban's rebellion through magical sabotage? Does Caliban deserve punishment for conspiracy, or does his enslavement justify any attempt at freedom? The comic tone—the drunken stumbling, the squabbling, the distraction by fancy clothes—masks darker undercurrents about power, rebellion, and the uses of magic to enforce control.
