These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: John Gillon, all the way. He tried fixing the last fight of Charles Macom Diggs by betting against him while the whole town bet on him, and when Diggs wouldn't go along, doped his nasal spray, which essentially turned his brain into a vegetable. And that's not even mentioning what he does to Slim after Ham loses his fight with Roy.
John Gillon: (after Caine has made him bet his entire fortune) Sounds like you know quite a bit about me, Mr. Caine.
Gabriel Caine: What I know about you, Mr. Gillon, would make Charles Macom Diggs himself stand up and walk.
