Why are the people no longer afraid of Tenorio? (chapters 13-14)?

Tenorio riles the people up by accusing Ultima of witchcraft. When he comes to the Marez home with his accusations, we see a glimpse of the superstitious fear of witchcraft that permeates the culture of the town. The men in the mob allow themselves to be stirred into a frenzy because they are afraid of what they do not understand. The test for witchcraft is an opportunity to place Ultima in a definable position: either she is a witch, or she is not a witch. Although the mob is eventually satisfied that she is not a witch, Tenorio's actions and accusations have taken away his influence with the crowd.
