The Question and Answer section for Romeo and Juliet (Film 1968) is a great resource to ask questions, find answers, and discuss the novel.
not an answer again... u r losing ur consistency :( T_T
I'm only guessing where in the film you are referring to. I think this relates to after the Capulet party. Mercutio thinks Romeo has gone sulking into the night over Rosaline when in fact Romeo has gone to Juliet's balcony.
