Ariel has informed Prospero that he has done his task that Prospero has sent him to do, which was to create the storm. As Prospero congratulates Ariel, Ariel brings up the fact that Prospero has promised him something and he is still waiting. But then Prospero gets mad because he has done so much for Ariel in the past.
As Prospero tells Miranda their background, he says that he was the Duke of Milan. Unfortunately they got kicked out of Milan and he was no longer the Duke.
Prospero tells Miranda that he is glad that they got to the Island all in one piece. He also tells her that the reason they got kicked out was because his own brother did this to them.
As Prospero tells Miranda about their past, Miranda starts to fall asleep. Miranda eventually falls asleep and someone else comes.
Prospero reminds Ariel that before he was his slave, he was Sycorax's slave and when he didn't follow her orders, she locked him up. He tells Ariel that when he arrived on the island he was still locked up.
