Nell mom had died and she is super sad. Mattie couldn't take care of Nell because she barely could take care of her self.
Mattie saw Eliza. She saw the women walking steadily away from me and that she held a large basket in her hand. She shouted Eliza name and they turned into an alleyway and disaperred.
Mattie was scanning the windows around the courtyard to look for Eliza. She heard the door close and it was Eliza at the bottom of the stairs. Eliza had no idea where was Mattie the whole time and why she had the bay girl with her.
