How does the author use foreshadowing in Bronx Masquerade?

Gloria and Lupe represent the two ends of the spectrum of teenage motherhood. Gloria loves her son. Lupe searches for love and believes a baby will fill the void in her life. Motherhood is represented as a duality, both as something unwanted and wanted. Both girls look at motherhood through very different eyes. Gloria's reality is not what Lupe dreams of. But Lupe's reality is not what Gloria sees. Both girls are at a standstill. This foreshadows that poetry may move both of them along to a better future.
