In Sanctuary the second man who rides in the truck that carries the moonshine that Lee Goodwin makes from Frenchman's Bend to Memphis literally rides "shotgun" - as the truck pulls away from the Frenchman's place, "the second man lays a shotgun along the back of the seat" (22). He teases the driver about his impatience to get back to his woman in the city.
In Sanctuary the man who drives the truck carrying the moonshine that Lee Goodwin makes from Frenchman's Bend to Memphis complains about having to wait for Horace, to whom he is giving a ride to Jefferson. "I got a woman waiting for me," he says (21).
The narrator of Sanctuary calls the people who board with Popeye's mother "clients" (304). None are described in any detail, but we know they include some "old ones" and one man who finds two fires in his room. The day after firemen discover Popeye's grandmother with a fire in the attic, "all the clients left" (305).
Standing outside Miss Reba's brothel in Sanctuary, Virgil and Fonzo see this "plump blonde woman" and "a man" get out of a taxi (192). The couple's behavior outside the door causes Fonzo to suck in his breath, and Virgil to assume that they must be married, but while the narrator never says so explicitly, it's clear enough that she is a prostitute and he is one of her customers. She disappears into the house.
In Sanctuary, while listening to State Senator Clarence Snopes talk about the life he lives in the capital of Jackson, Horace conjures up images of "bellboys" with "bulging jackets" (presumably contained alcoholic beverages) making deliveries to "hotel rooms" (175).
When Temple in Sanctuary thinks of the baseball game in Starkville that she is missing, she imagines "the green diamond dotted with players." The description of their playing is unmistakably in Faulkner's words, however, not hers: "encouraging one another with short meaningless cries, plaintive, wary and forlorn" (37).
This fellow student at the barber school with Fonzo and Virgil is presumably the person in Sanctuary who, twelve days after they have started sleeping at Miss Reba's, tells Fonzo about the existence in Memphis of a house of prostitution. At any rate, he accompanies them to "that house" after Fonzo convinces Virgil to go (196).
The aunt of Temple who lives "up north" in Sanctuary may really exist, though it is clear that when the local newspaper in Jackson publishes the news that Temple's father has sent his daughter to spend time with this woman, that is a fiction intended to cover Temple's disappearance from college (176).
The "two figures" Horace sees locked in an embrace in "an alley-mouth" in Memphis in Sanctuary are probably outside Miss Reba's house, though it is possible they exist only in his mind, which is reeling from his encounter with Temple inside the brothel and the story she tells him about being raped. The behavior of the couple certainly matches Horace's fascinated revulsion with sexuality: the man whispers "unprintable epithet after epithet" caressingly; the woman swoons with "voluptuous ecstasy" (221).
