How does A tempest end?

Ariel has readied Alonso's boat for their departure, and the boatswain shows up again, telling them about what happened to all of the sailors during the tempest.

Caliban apologizes to Prospero for taking the foolish Stephano as his master, and Prospero, at last, acknowledges Caliban, and takes him as his own. Stephano, Trinculo, and Caliban's plot is exposed to the whole group, and is immediately forgiven. Prospero invites everyone to pass one last night in the island at his dwelling, and promises to tell the story of his and Miranda's survival, and of the devices of his magic. The play ends with Prospero addressing the audience, telling them that they hold an even greater power than Prospero the character, and can decide what happens next.
