In The Sound and the Fury, as part of his fictional alibi, Jason invents this "sister" of the fictional "showman" who borrows his car; her equally invented husband is supposedly involved with "some town woman" (258).
As part of his fiction about loaning his car to a showman in The Sound and the Fury, Jason invents an adulterous "brother-in-law" involved with "some town woman" (258).
In The Sound and the Fury to refute his niece's accusation that he has been following her, Jason invents a story about the "showman" who borrows his car to chase after his "sister's husband" (258).
Readers of The Sound and the Fury never see the band that plays in the traveling show visiting Jefferson, but several of the novel's black characters talk about it, and in Jason's section both he and Uncle Job hear the music they are making. "That's a good band," Job says (248); "Dem folks sho do play dem horns" (230). Jason refers to the show's performers as "a bunch of Yankees" (230), but there's no clear evidence that they come from the North.
In The Sound and the Fury the old "man in a dirty apron" Jason spots at the train carrying the traveling show in Mottson is probably a cook. Though smaller than Jason, he becomes a "puny fury" when he feels Jason has insulted him, driving to get to his "butcher knife" and then attacking Jason with a "rusty hatchet" (309-10). As the owner of the show later tells Jason, warning him to stay away from the show, "That damn little wasp'll kill you" (312).
After leaving Parker's in The Sound and the Fury, Quentin notes that "two bootblacks caught me, one on either side, shrill and raucous, like blackbirds. I gave the cigar to one of them, and the other one a nickel" (83). Though the text does not make their race explicit, the "blackbird" image suggests that these two individuals are African American.
In The Sound and the Fury Miss Quentin, like her mother Caddy, is sexually active as a teenager (and also seems to be pregnant, as Caddy was with her, out of wedlock). Jason is sure that his niece makes herself available not only to all the "slick-headed jellybeans" (184) and "dam squirts" (188) in Jefferson but to "every dam drummer and cheap show [man] that comes to town" (239).
In The Sound and the Fury this "man who mutilated himself" by cutting off his genitals with a "broken razor" is known to readers only through Quentin's recollection of a story Versh tells him (116).
