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.
Ear Worm: The background music, which plays and loops continuously throughout game-play.
Fridge Horror: In the Airport arc, we find out that Chief King's suicide was because the Crimson Order would kill Cathy if he were caught. This raises questions about the families of Alden Greene, Ashton Cooper, and Luna Hecate, all of whom were arrested for murder, as well as Jason Palms, Anakee, Herman Cavendish, Jenny Quaid, Constance Bell, and any other people who helped to take down the Crimson Order.
Alden Greene is pegged for most of the Financial Center arc as a Corrupt Corporate Executive who's suspected to be involved in some very questionable transactions, who believes money can solve any trouble, and who's a Smug Snake in general. Then he murders recurring character Rachel Priest with an injection that causes her to die a horrific death, in order to keep her from revealing the unethical Super Soldier program he's about to bankroll.
The Rorschach Reaper is already a heartless Serial Killer and master manipulator. Who then goes on to hypnotize Jones into attempting to murder the player character.
Milton Grimmes is the head of an organization that is implied to be behind almost all of Grimsborough's murders, including the murders of Rachel Priest and Adam Bentley. Then, he points a gun at the player character.
Erikah Mabayo is the second Serial Killer in the game behind the Rorschach Reaper, and it shows. Even beforehand, she is responsible for several minor crimes in Bayou Bleu, but in Case 10 it is discovered that she killed 4 24-year old prostitutes for no real reason, including one of the only sympathetic characters in the bayou, singlehandedly ruined Harvey Fitchner's career, found the only witness and blackmailed him, then started the voodoo craze to give herself power.
Shipping: Ever since his introduction, many players have shipped Russell with Amy.
Ships That Pass In The Night: And before Russell's introduction, Amy was shipped with Jones, whom she never interacts with due to them coming from different districts.
Andrew Kamarov. In his first appearance in chapter 15, he lost his mother and was kidnapped shortly afterwards. His nanny, whom he seems to care about, was arrested for the murder. In chapter 17, he was orphaned when his father was also murdered.
