Surrogate

The girl acted a little awkward when meeting Alex for the first time. She understood that he was different from her father, so the experience was very unique and not so pleasant for her.

Especially because she understood the importance of his existence. After all, biologically speaking, she knew that it was him who was her real father.

Alex was confused about that aspect too. His clone had told him the same thing and now the young girl in front of him was telling him the same thing as well.

"Can you explain to me why she and my clone think that I am her biological father?" Alex asked using his spiritual sense.

The man heard it and gave a reply with his spiritual sense as well.

"Back when I first made clones, there was one thing I was worried about more than anything else. It was the fact that sending genuinely talented folks out into the world full of not-so-talented ones, I would soon cause the uniqueness of these humans to dissipate."
