Trivia: It's noticeable that the series drops in quality in season 3. This is because ABC hired the consulting firm "Q5" to rework their lineup in an attempt to boost ratings. Unfortunately, Q5 seemed to misunderstand the series, and forced the creative team to unnecessarily change it. Their changes included making Janine a blander character and relegating Winston to just being "the driver." The crew hated the changes, which they felt were often racist and sexist. Some even left out of protest.
Trivia: Dio in this episode drinks Cronenberg Whisky, just like in the manga. The fictional brand is most likely a homage to the director David Cronenberg, especially given the bit of 'body horror' appearing in this arc.
