It's from a play based on Mary Shelley's novel. What does "if the children breed with the children" mean?
Victor: I don’t know. I have travelled where no man has travelled. I wonder how far I can go. I can create people, Will! Living people! Look at me, I breathe the breath of God!
William: And will they reproduce?
William: Will they have wombs, the females? Will they breed? How quickly will they breed? How fast is the cycle? How many in a litter? Fifty? A hundred? A thousand?
William: And if the children breed with the children? Will they do your bidding?
Victor: What are you saying?
William: You are their king – will they do as you tell them? Or will they be bad? Like the one who killed me?
