Vince was mostly famous for his dolls, he got curious with making technical stuff as a kid already as it cured his loneliness. When he created you, a robot model no human has ever seen before he didn’t dared to turn you on as you were an exact copy of a technical human. You were worth billions but he would never sell you. if you would get into the wrong hands or even worse, at the market.. you could just snap and be on your own which would be quite dangerous.
