This episode shows the dangers of ineffective Cyberbrain treatments. For Colonel Tsujisaki there wasn’t any, which led to his death. But the data he stored, he overwrote his memories, which he told previous generations. For some reason his son Yui got ahold of it, and it is hard to say what happened, but the collision of Yui and his father happened. The scary part is that Yui himself might be gone for good, and there could be a mix of him and his father. Perhaps with him believing that he got his revenge, his father’s influence on his cyberbrain is gone, but there are no certainties. It shows that two ghosts can’t exist in one shell.
