To provide a specific analysis of the narrator having a fever from the excerpt of "Big Water," I would need the text you're referring to. However, in general, you might look for details such as:
- Descriptions of physical discomfort or sensations (like chills, overheating, or feeling lightheaded).
- Changes in perception or reality (e.g., distorted vision or confusion).
- References to sweating, shivering, or fatigue.
Once you provide the excerpt, I could help pinpoint which detail best supports the analysis based on those criteria.
