* BigLippedAlligatorMoment: Chapter 2 when Pearl finds Steven [[spoiler: watching porn]].
* HarsherInHindsight:
** Chapter 8 shows Zoisite [[spoiler: brutally raping 12-year-old Connie]]. The following chapter has an Author's Note dedicated to [[WebVideo/YouCanPlayThis Justin Carmical]], who'd killed himself that year in 2014. Four years later, he was posthumously revealed to have sexually groomed underage girls while still a producer at Website/ChannelAwesome.
** Steven [[spoiler: [[AccidentalMurder kills Zoisite and Zircornia completely by accident]]]] at the end of Chapter 13 and then [[StressVomit expresses remorse over what's he done by puking]] in Chapter 14. Steven himself would not [[spoiler: kill (or shatter) a Gem]] until over five years later in ''WesternAnimation/StevenUniverseFuture'' when he [[spoiler: accidentally shattered Jasper]] in the episode "Fragments."
* NauseaFuel: Pretty much every scene that's {{Gorn}} could count as this.
* NightmareFuel: Zoisite's first murder while in blob form is described in graphic detail. Also, the subsequent murders he commits are this.
** Seriously, good luck trying to forget that he liquefies people to death.
