I am confused about Alice (SPOILER) Okay so I think I‘m almost done with the game so here‘s a question about Alice. 

Later in the game we find out Alice is an Android too. But why does Kara not know this? She was with the family before and I think Androids don’t have to eat but she cooked for Todd and Alice, plus when running away from him, Alice is sick and needs sleep. So was she an Deviant before Kara was? And why didn’t Alice have an ring on the side of her head, like other Androids (normally) do? Todd was also talking about her mother. 
I may have missed a lot of clues, been playing the game for the first time but maybe I was just too blind to see it. 

Sorry for my English, I‘m not a native speaker.
