[Willona opens the back of Penny's dress, revealing her back's covered in bruises
] Oh no!
Wha - what happened?
[turning around quickly
] Uh, I fell, I always fall, my feet are all thumbs.
Baby, come here. Now I know you like to make up stories, but I need you to tell me the truth. Who gave you those bruises? Baby, who did those awful things to you?
[enters and sees Penny's dress open
] What's going on?
] I didn't tell them a thing, momma, honest I didn't.
[goes to her mother
[hastily ties up Penny's dress and trying to act innocent
] What would you have to tell them, sweetheart?
