Juliet convinces the Nurse and Lady Capulet to leave her the alone. Then she takes out the potion the Friar gave her. She worries for a brief moment that it might be real poison.
She freaks herself out by imagining what it will be like to awake surrounded by a bunch of dead bodies, including the fresh corpse of her cousin Tybalt.
She drinks the potion, but makes sure to fall on to the bed instead of dropping awkwardly onto the floor.
