Who does not get married at the end?

The Trickster of Seville by Gabriel Tellez ends with a number of marriages, as the King seeks to resolve the various issues that have been created by Don Juan over the course of the story.
As a means of returning order to the land, the King orchestrates the marriages of Ana to Mota, Octavio to Isabela, and Batricio to Aminta. Because these marriages are depicted as examples of the King dispensing proper justice, however, it is fitting that Tisbea the fisherman's daughter remains unmarried.
This is intended to be a punishment for Tisbea's behavior. She believed Don Juan when he promised he would marry her in return for her assistance, but ultimately everything she did in pursuit of this goal helped Don Juan carry out his disruptive works. As such, as an ally of Don Juan, Tisbea is punished in that she is the only person who is not married off at the end of the story.
