Final answer:
Without knowing the specific literary work or context, it is not possible to describe how Patricia deals with Trevor shoplifting batteries in chapter 17, as this situation appears to come from an unspecified fictional source.
Step-by-step explanation:
In chapter 17, Patricia's response to Trevor shoplifting batteries at the mall is not provided in a specific text, as this scenario seems to be from a fictional work or a book not identified in the question. Therefore, without knowing the specific text or context, it is impossible to accurately describe how Patricia deals with the situation.
In general fiction, characters dealing with shoplifting might respond with concern, anger, disappointment, or by taking action such as confronting the individual, seeking help from authorities, or attempting to return the items. However, providing a specific answer requires knowing which book and characters are being referred to.
