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.
YMMV: The Chicago Code
Genius Bonus: Episode 9 revolves around a multiple murder that is paralleled with the St. Valentine's Day Massacre; the prime suspect is named Dion, which was also the name of Dion O'Bannion, the onetime leader of The Irish Mob, who were the victims of the original massacre (although O'Bannion was killed before the massacre).
Magnificent Bastard: Gibbons of course. He's always a step ahead of everyone. Too bad he wasn't as careful when he was younger (see Smug Snake entry).
