* HarsherInHindsight: In ''On A Pale Horse'', Lachesis defends Fate's meddling in Zane's life by saying that "all mankind will be damned" if they don't meddle. Come ''For Love of Evil'', we learn that Satan doesn't actually intend any such thing. Quite the opposite actually. [[spoiler: His bid to claim God's power is motivated by a desire to stop people from being damned unfairly.]] The idea that the forces of Good may have actually been preventing a desirable outcome (and unwittingly subjecting countless innocent souls to damnation) by their interference is some pretty serious FridgeHorror.

* TearJerker: Fate having to comfort Norton's successor/predecessor, a six-year-old boy.
** Also, a previous Chronos being broken at realizing that from the POV of Niobe, the woman that he had loved for 35 years, they are only meeting for the second time.
** Orlene meeting God, except God is so narcissistic that He does not react to anything anymore.
** The wedding at the end of book 5.
