Dar e Nijat Theory

After seeing Abu Bakr's requirements for his wife, I feel like the his and Zaryab's marriage will happen due to his mother's wish. His mother will see her own past in Zaryab and convince her son to marry him. Why Zaryab will agree to marry him is pretty clear coz Zaamil taunted her that a man like Abu Bakr would never marry a woman like her.
