Whatever makes Hank so attractive when he's fishing is genetic.Generations of Yarbo men have been inadvertently seducing the women of Saskatchewan, spreading their genes far enough that everyone in the area now has some small traces of Yarbo DNA. Hank has the purest strain, but it manifests in every other Dog River citizen as a streak of complete insanity.
Lacy deals drugs (from the city) to the residents.When Hank asks "Where's your F n' E?" (in response to the letters missing from her cafe). Lacy immediately responds "this is a family restaurant, Hank", not following up with "and what are you talking about?"
Robot versus Werewolf would be a stalemate.Hank fails to consider that while the werewolf has supernatural claws and strength, it would at best do cosmetic scratch damage to the robot's steel shell. Inversely, mechanical steel fists or claws would be unable to inflict any wounds that the werewolf couldn't heal almost instantly.
