How does this monologue foreshadow future developments in the play? what element of conflict is established? romeo and juliet (act 1 scene 1) in advance1

There are no monologues in Act 1 Scene 1. Based on Romeo's two longer lines in his dialogue with Benvolio ("Alas, that love, whose view is muffled still, / Should, without eyes, see pathways to his will!" and so on), Romeo foreshadows the future events by implying that fights and disasters can happen because of love. "O heavy lightness, serious vanity, / Misshapen chaos of well-seeming forms! / Feather of lead, bright smoke, cold fire, sick health, / Still-waking sleep, that is not what it is!" There is a conflict between a presupposed order that love should bring, and the chaos that it really brings.
