In the excerpt from "Thankless in Death" by J.D. Robb, a character questions another's energy and stamina, noting that they don't seem exhausted despite recent physical exertion. The response highlights the importance of a good meal, mentioning that a satisfying lunch and a small snack helped maintain their energy levels.

The dialogue also hints at the urgency and action of the earlier situation involving a chase. One character suggests that if the other had eaten properly, they might have been able to keep up in the pursuit, subtly commenting on the relationship between nourishment and performance during high-stress tasks.
