. i tend to think of N refusing therapy for some reason
. i also hc that uzi didn't tell anyone about the solver in her tail.

. i hc that tessa was punished by her parents with just the chains, while, as i think, her parents show distain at the robots, so while tessa got chained in her room, the worker drones got harsher punishment based on what they did (this also is hinted from N's punishment for insulting tessa's mother)
. robots can get sick in someway.
