What's a Living Thing?
The marionettes learn about life and death when Lime adopts a squirrel for a pet. As Lime nurses the squirrel back to health, and then chooses to set the squirrel free for its own good, the marionettes experience new emotions, proving that their maiden circuits are continually growing, just as the Shogun said they would. When the Shogun hears of the pet project that the marionettes have undertaken he is pleased because the growth signifies one step closer to reviving females on Terra II.
