How does the author use foreshadowing in The Wolf and the Dove?

Ragnor de Marte's role as Aislinn's captor foreshadows his continued determination to claim her by right of conquest, even after failing in the joust ordered by the King.

Gwyneth, Wulfgar's sister's belief that Ragnor had Aislinn first, foreshadows her jealousy and determination to make Aislinn's life miserable.
