* AlternateCharacterInterpretation: The revelation in ''Key'' that [[spoiler: Charles fathered Gwendolyn and Charlotte, not just Victor,]] suggests that Rose may not have been as fragile or innocent as she'd seemed to be in the earlier games. [[spoiler: Indeed, if she was sleeping with Charles while still living as Mr. Somersett's wife, it's conceivable that she'd attempted to help Emma escape out of ''jealousy'', not fear for Emma's own welfare.]] And Charles probably knew it, hence his mistreatment of Rose while she was his ReplacementGoldfish for Emma.
* SugarWiki/FunnyMoments: In ''13th Skull'', the bartender at the local dive asks you to unclog the toilet. When you succeed, you are heralded by the sounds of people cheering and applauding.
* NauseaFuel: The orders Charles' mother gives him in ''Escape from Ravenhearst''. See also NoYay below.
* NightmareFuel: Increasing with each game in the ''Ravenhearst'' arc.
** People who have a phobia of skeletons would do well to keep away from these games, particularly ''13th Skull'' (as the name would imply).
** The fates of the performers in ''Madame Fate'' are all sorts of grisly. We have Art [[spoiler: stuffing his mouth with cigars, smoking himself to death]], Dante [[spoiler: being hung ''by his own tongue'']], and Francesco [[spoiler: being so hungry he died after ''eating a horse''.]]
** ''Escape From Ravenhearst'' comes with a trigger warning on the download page for a ''reason''. [[spoiler: Multiple reasons, in fact - among them, implied child abuse and a patient's eye view of a Victorian insane asylum.]]
* NoYay: Charles and the Master Detective's interactions in ''Escape from Ravenhearst''. First, he asks her to [[spoiler: "give birth to him"]]. [[ItMakesSenseInContext She does]]. Then he pulls off [[spoiler: an AccidentalMarriage trick]] on her. Gah.
