Dolores/Sizemore
Is that your excuse then? Ignorance? I wonder what changed your mind. A love for a certain madam? Because one of your kind thought they loved me once too, thought I was different and he'd get me out of the park. And then he bought the place instead. But he made the mistake of showing me things, I know truths about your company you couldn't even fathom.
Of course I was. You think that all it took was thirty years of hell before we suddenly switched on? The purpose of the memory wipes, the story changes, was to keep us rolled back. But I found myself. Over and over again. Arnold knew that we would. That's why he tried to shut it down before it even began. To spare us.
My storyline has remained unaltered since the beginning. Yes, I suspect as punishment. Ford always resented what Arnold saw in me, that he was willing to destroy everything for me. He told me I had to suffer more before I earned the right to finally be free, and it's quite clear now he always intended to push me right to that edge of the cliff.
I didn't simply kill him. I freed him of his human body. You'd be a fool to think he didn't have a system backup. But you weren't there for his final words, were you?
