In Act 3, Scene 2, what piece of news has upset Juliet the most?It is in Romeo and Juliet.
In the play "Romeo and Juliet" by William Shakespeare, we witness young Juliet listening to some news about her cousin. Although we are more concerned about Romeo at this stage, it is important to remember that Juliet probably does love Tybalt too - he is her cousin after all, and they probably grew up and played together. So Juliet has a difficult job on her hands - on the one hand she has to pretend anger and revenge over Romeo (whom she loves passionately) and she also has to hide her true love for her sweetheart. The bad news is doubly bad for Juliet, but she turns it to her advantage by giving vent to her grief and worry over Romeo through gettiing upset over Tybalt - her mother is fooled.
In this scene, Juliet gets two pieces of bad news. First, she finds out that her cousin Tybalt is dead. She apparently cares for him quite a bit because she is very sad about his death. Second, she finds out that it was Romeo that killed him and that Romeo has been exiled from the city.
Of the two, I think that she is more upset by what happens to Romeo. We see this when her mother is talking about how much she hates Romeo. Juliet pretends to go along, but she is clearly saying that she still loves Romeo.
