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: Nicholas Quinn. He lured two office cleaning ladies to his country house, where he held them against their will, drugged and raped them over a period of several days, then forced them to keep quiet by threatening to have their work visas revoked should they ever leave the country, as well as keeping them from bringing their families with them. This is the Attorney General of Australia we're talking about.
The Woobie: Richard. Possibly the most likeable main character, and he is put through hell and back by the writers every single episode. He also finds it incredibly hard to deal with, making him prime woobie material.
