Joe: So, what was that back there?
Karen: I cannot deliberately place myself in immediate physical danger.
Joe: So, what, you've got an override? Some kind of self-preservation thing?
Karen: In a way. David Elster's wife took her own life. He hardwired my programming to ensure I could never do the same.
Joe: So, no throwing yourself into oncoming traffic, then?
Karen: It means I can only protect Sam if it poses no threat to my own wellbeing. I can't be a mother.
