Transcripts
Madison Li: This is day... eight of trial six. The last week has been very productive, but exhausting. I think we'll need a break after this. Binet has done some really marvelous work with the personality mesh. It's... well, it's almost too good. The responses map almost identically to expectations... Some of the most life-like I've seen. Of course... It's not really Shaun. None of his memories are in there. That, even now, would be a step too far. It's starting to have an effect on the team, I think. I know I've been caught up in the moment once or twice... Just a second or two... forgetting that he's not a real boy. Still, I think we'll need to consider restricting him to the lab only for the moment. I'm well aware that others are... put off by his presence. If I were slightly more arrogant, I might consider that a sign of success...
