What are some examples of foreshadowing in act 2 of Shakespeare's Romeo and Juliet?
Whenever one is asked to find evidence of foreshadowing in Shakespeare's Romeo and Juliet, look to the Prologue, Chorus, or Romeo's dialogue for answers. The Chorus is the voice of Fate which is like an omniscient narrator guiding the audience along through the warnings at the beginning of acts. Romeo is very in tune with Fate and has dreams that he feels warn him about the future. Both of these are places where foreshadowing is found. For example, the Chorus explains the current situation at the beginning of act 2 and explains that lovers usually have time and means to meet to express "vows" to each other, "but passion lends them power, time means, to meet,/ Temp'ring extremities with extreme sweet" (II.Prologue.13-14).
Another quote that has foreshadowing elements happens before Romeo and Juliet are married and Romeo is talking with Friar Lawrence: "The love-devouring Death do what he dare;/It is enough I may but call her mine" (II.iv.7-8). It's as if with this quote Romeo is tempting death or fate to intervene!
