Final answer:
The provided text excerpts do not contain information about what Wendy orders when David asks her. Additional context or text is required to accurately answer this question.
Step-by-step explanation:
From the provided information, it is not clear what Wendy orders when David asks her, as the text excerpts given do not directly reference a scenario where Wendy is asked to order something by a character named David. The excerpts seem to come from different contexts and don't provide enough detail to answer the question about Wendy's order. From the first excerpt, we can discern that a character named Wendy is involved in a situation concerning a nursery door that was not locked. In contrast, the second excerpt introduces a character named Harry who suggests that it is time for dinner, but this does not specifically relate to Wendy or her actions in regards to ordering anything.
Without the relevant information or context, it is not possible to determine what Wendy's actions might have been in response to David's request. To accurately answer this question, it would be necessary to have the appropriate part of the text where the interaction between Wendy and David takes place, especially if it involves a dialogue where Wendy is expected to place an order of some kind.
