The Ritsuko episode was as straight as arrow, and thus impossible to spoil. Tell me if you did not guess that Ritsuko had to substitute for a member of Ryuugyu Komachi. What’s strange, however, I did not feel bored about the predictability. It was a comfort food episode before another showdown with the forces of evil.
It could have gone another way. For example, potentially delicious interactions with Ritsuko’s old fans did not get a play. But it’s all right, I am satisfied anyway.
By the way, there were a few shots of Kotori in civvies.
