The Duke heard the conversation between the siblings and glanced again at the undead, who were indeed dressed like the ordinary townsfolk here.
Neither he nor Vivian had entered Black Oak Town during the day, so they had no impression of these townsfolk.

The Duke realized that the present situation was likely related to the day's cleansing, even saying that Leonard's sibling's massacre led to the current scenario.
They were implicated, though it's not entirely Leonard and Ella's fault, as the mission above demanded a carpet search and cleansing.
The two were eager to claim credit, so they actively executed the task, being the first to arrive in Black Oak Town.
