Sancho sleeps in the same chamber as Don Quixote. He would prefer his own quarters so he could get some sleep and not be disturbed by the restless Quixote. Quixote starts discussing Altisidora, who died from unrequited love of him.
Sancho complains he had nothing to do with her death or her falling in love. He begs to be allowed to sleep.
They both fall asleep.
Samson Carrasco had learned of Quixote's whereabouts from the page that brought the letters to Teresa. He asked the road Quixote had taken from the duke and duchess. The duke told him of their practical jokes, which amuses Samson. When Samson returns from vanquishing Quixote, he gives the duke an update before returning home.
The duke then sends out men on horseback and orders Altisidora to play dead so they can have more fun at the expense of Don Quixote and his squire.
Altisidora greets Quixote the next morning, blaming her for her death. She has Sancho to thank for restoring her. Sancho asks about what the netherworld is like. She told Sancho she came to a gate where devils were ill-temperedly playing tennis with one another. The tennis ball was the second book written about Don Quixote, which made her remember him.
Don Quixote once again reiterates that he is sorry that Altisidora loves him, but his heart belongs to Dulcinea. Altisidora tells him that what he has seen is all make believe. She is not somone to die out of unrequited love.
The duke and duchess enter, and Don Quixote asks his leave of them. A vanquished knight doesn't deserve to live in splendor. The ask if he has reconciled with Altisidora, and Don Quixote replies that Altisidora has too much time on her hands.
Don Quixote and Sancho leave that evening.
