Final answer:
The incident with the Nagual likely reveals character traits such as bravery and resourcefulness, and it might also illustrate themes like community and cultural connection.
Step-by-step explanation:
The inquiry about what the incident involving the Nagual on pages 187-192 reveals about Odilia and Juanita implies a narrative context where characters interact with mystical or supernatural entities. Without access to the specific content of those pages, we can deduce that such an incident likely demonstrates aspects of the characters’ bravery, resourcefulness, and possibly their connection to cultural or familial traditions. Analyzing characters' reactions to supernatural incidents is a common way to explore themes like alienation, community, humanity, and the mystical in literature.
