I'm worried the reviewer isn't actually human and isn't able to pick up on all sorts of cues, based on the reviews I've read thus far. Karen, I'm sure in part due to her emotions and Elster backstory, believes synths were a mistake and told Niska as much. Niska chose to withhold this information from the others.

I never cared for this show until some point in season 2. I ended up really really liking season 2!
