This foreshadows the tragic consequences of the well-intentioned but ultimately ill-fated plan.
4. Nurse's Misinterpretation: The Nurse misinterprets Juliet's emotional state and assumes she is distraught over Tybalt's death, rather than the potential separation from Romeo. This misunderstanding further complicates the situation and highlights the communication barriers that contribute to the tragedy.
