Genevieve refused to leave her room after the fight with Rhett. She was mad at him for suggesting she didn't see Kenneth again. She would not allow him to control her life. She had a life before marrying him, or before he bought her.
Genevieve had dinner in the room; since 'her husband' wouldn't allow her to leave the room; she might as well stay and lock herself inside it. She refused to see anyone or talk to the maids who returned with her belongings after being instructed by Rhett. She planned to stay in her room for as long as she could.
That night no matter how hard Genevieve tried to sleep, she couldn't. Her eyes always went to the door for any sign of Rhett or she would walk towards his balcony to see if she could see his car driving in. But nothing.
