The next morning, day of the wedding, the house is very busy preparing for the wedding that day, because they have not yet realised that the bride is "dead". Capulet tells the Nurse to go wake up Juliet.
When the nurse arrives upstairs to wake up Juliet, she realises that she is dead. Capulet, Lady Capulet, Paris and the nurse mourn her death but Friar Lawrence assures them she is in a better place.
Juliet tells the nurse to leave her sleep alone, and tells the same to Lady Capulet afterwards. Once no one is there, she drinks the potion, but first thinks about what will happen if it doesn't work, and gets worried.
