How does the author use foreshadowing in Marry the One Who Gets There First?

In Photo 25, which suggests that Black has sex with one of the college women who works in the kitchen, Julavits foreshadows the ending in which he picks June up on the side of the road leading from the lodge. In addition, the author uses omens and signs seen by various characters to foreshadow coming events. Rose Sheidegger, for example, believes she was fated to marry her husband when he used a quotation her grandfather used. Her future husband, however, learned the saying from a mah-jongg parlor owner who told him it works ladies like charm. Later in the story, Rose laments that she married the wrong man.
