Because the nurse is her trusted adviser, and basically like another mom to Juliet. ;)
Although there are many themes of "The Landlady" by author Roald Dahl, one of the main themes is appearance vs reality. The Landlady is very nice and generous towards Billy which causes him to ignore the sinister plot the Landlady is conjuring.
I believe these parts provide direct characterization: "<span>Endowed with commonsense, as massive and hard as blocks of granite, fastened together by stern rigidity of purpose, as with iron clamps, he followed out his original design, probably without so much as imagining an objection to it."
The writer clearly and directly describes the character's personal features, as well as his internal motivation for an action. It is opposed to indirect characterization, where we can grasp the character's traits or motivation through his/her actions or speech.</span>
