Leroy really didn't understand Ainsley's hatred toward him.
It's not as if he wronged Ainsley's mom either, because she's just a surrogate mom, a baby carrier.
The woman also knew about this and didn't have any affection for Ain, the baby she gave birth to.
After all, she's an ability user, and her ability was actually fertility and childbirth.
For her, she could give birth to a lot of children without feeling any discomfort or pain. She could even allow the children to inherit the parents' good genes or abilities to an extent.
Many couples who couldn't have children used her as a surrogate mother, making her the baby carrier.
The eggs and the sperm all belonged to the parents while she was only a carrier.
In Leroy's case, the eggs were chosen from an ovum bank, and they chose the one with the best combination with Leroy's genes.
That's how Ainsley was born.
In a sense, she was born to be a mafia boss.
