Read juliet's last speech in the excerpt: juliet: o fortune, fortune! all men call thee fickle. if thou art fickle, what dost thou with him that is renown’d for faith? be fickle, fortune, for then i hope thou wilt not keep him long but send him back. what effect do these lines create? they flash back to scenes in which the characters playfully discussed fortune; thus, they add a brief touch of humor. they provide a momentary easing of tension by foreshadowing romeo's return to juliet's side. they use flashback to remind the audience of romeo's deep faith, leading the audience into a hopeful mood. they increase suspense, because by calling fortune "fickle" they hint at an unlucky end for the lovers.
