I was amused by the blogger's observation that a villain who mistreats his horse is likely to be unseated at an inopportune moment. In fact, back in high school, I wrote a story in which the climactic confrontation was cut short when: the villain spurred his horse, it reared up, he fell off and broke his neck. The heroes were left staring dumbly at the corpse and wondering what to do with all their adrenaline.
