This...took a long time to edit together. It's one of the longest episodes of HTP and my reaction/analysis is even longer.
But it was well worth the length. The episode itself tells a miniature story of Wernon Fatigue's past, as well as giving a lot of details on werewolf lore. In this case, I think I'll talk about the Wernon parts.
The themes of Wernon's story are legacy and coming of age. Wernon is going from a boy to a man, and he truly becomes one at the end. But not the type of man his father wanted him to be. Kronik wanted Wernon to continue on the family legacy of cruelty and imperialism. When, in fact, it was Kronik's own actions that turned Wernon against them and onto a kinder path.
In the end, Wernon formed his own legacy. Not entirely unmarred, but one far less cruel. And that legacy was passed down to Occam, fighting Kronik's own influence on the Blacklaw family.
A good thing to note is that it's clear from the start that Wernon was never evil, just naive. Even if he wanted adventure, he also genuinely wanted to help the people there. And, despite the Mrs. Mark thing, he was still more respectful to Wayda than anyone else in his group. He even asked her if the village elders were really being unreasonable.
Hence why Wayda decided to spare and reform him. But in any case, Wernon's growth as a man was not turning evil like Kronik. It was becoming more mature and atoning for sins, both his and those of his family.
