So that's where the robot comes from. Wonder how both Nagisa and Tomoya know it though. Maybe they shared some past event together? Sunohara was actually serious and rational this episode. Given how good a friend he is to Tomoya, and probably deep down already knows their relationship, he lets Nagisa go, if he ever had her at all. Akio blunders all over the show building up for his last one. I wonder what his dream was though.
