The members of the Classics Club were in the club room. After a helicopter flew over the school, Houtarou suddenly remembered a middle school teacher, Ogi Masahiyo, and his love of helicopters. Satoshi and Mayaka had vague memories of Masahiyo, and the former remembered the teacher saying he had been struck by thunder three times. Houtarou became curious and went with Chitanda to the public library to investigate. They discovered that Masahiyo had been a mountain climber and one time at school was glad to see a police helicopter fly over the middle school because two climbers had been stranded in the mountains at the time.
Episode 18 of Hyouka had a self contained story. I wanted to see an episode leading to a conclusion but its episodic nature is good. It was funny when Satoshi and Mayaka made fun of Houtarou for wanting to do something. My hope for a romance between Houtarou and Chitanda seems to be going in the right direction. But Houtarou does not seem to notice the subtle hints of romantic feelings coming from Chitanda. This episode gets a 8 out of 10.
