WOW, this episode was PACKED! So much lore packed into a short time, and they finally tied up several loose ends regarding Esola's relationship with the KNoCC androids. My opinion? Professor Shibaura Hakushu is a despicable man. A degenerate old man who, obsessed with a young girl, ruined his own life and almost the life of his adopted son. Not everything is his fault; the traffic accident and the terrorist attack weren't his doing, but he definitely didn't make the best decisions. Being so determined to make his son the perfect human, he forgot that to achieve that, he himself had to act like a father. But overall, an excellent episode. The conflicts are very well-developed and feel realistic. It's both emotional and surprising.
