After he betrayed her and gave birth to a child by another woman, and then her mother died during childbirth, He came to her and said:
Troy: Rose, I'm standing here with my daughter in my hand. It's us. Young and not aware of adult matters. She is innocent, she has no mother.
Rose: Why are you telling me that?
Troy: She's my daughter Rose of my flesh and blood I can't deny that I can't deny her because she's family like our sons, you and this baby are all I have in this world so I guess what I'm saying is I appreciate that you help me take care of her.

Rose: Okay, Troy, you're right. I'll take care of your baby for you, cause like you say, she's innocent. You can't put the sins of fathers upon child. Motherless child's got hard time. From right now this child's got a mother.
But you a womanless man.
