I can see the logic of what you're saying, I'm just surprised that the desires of the child seem to have been ignored. I guess ultimately they just decided to focus on different aspects of the story. A follow up would definitely have been good.
I watched Whispers today. A great episode, probably one of my favourites of the season, you really feel sorry for the replicant and the abrupt death at the end is really quite shocking, especially how they talk to him as if he's not a person.
