Where does foreshadowing occur in the book, Beloved?

“There was no blood. Mr. Garner came home bent over his mare's neck, sweating and blue-white. Not a drop of blood. Sixo grunted, the only one of them not sorry to see him go. Later, however, he was mighty sorry; they all were.” (pg. 381)

The above quote foreshadows Sixto's knowledge that Garner was, in fact, the lesser of two evils. Something... or someone, will be worse.
