* ActingForTwo: Dana Sparks portrays both Grace and Faith Standish. They are identical twins.
* ChannelHop: Given its already strange status, it's no surprise that it also had a very weird network switch; specifically, the show moved from Creator/{{NBC}} to [=DirecTV=] and its exclusive channel, The 101 (later known as Audience Network and ultimately taken off the air in 2020, as Creator/HBOMax was now more important to AT&T's ill-fated media ambitions). However, NBC continued to make the show, and [=DirecTV=] declined to renew the show after one season.
* TheCharacterDiedWithHim: Timmy was Tabitha's faithful companion for centuries, always being sewn back together once Tabitha had reincarnated into a new form. He even survived a few maulings by their familiar, a bitchy house cat. Timmy finally ran OutOfContinues when Tabitha reluctantly implanted his heart to Charity to de-zombify her. Ironically, Josh Ryan Evans died the day after his death scene was aired; Evans was slated to return in a new guise, but succumbed to a heart condition.
* TheOtherDarrin: Too many to list, [[http://en.wikipedia.org/wiki/Passions#Cast so here's a list]] from Website/TheOtherWiki.
* RomanceOnTheSet:
** Lindsay Korman (Theresa) and Creator/JustinHartley (1st Fox) first met on the set of the show. They married in 2004 but divorced several years later.
** Creator/NatalieZea (2nd Gwen) and Travis Schuldt (1st Ethan) have been together since appearing on the show at the same time and welcomed a daughter in 2015.
** Ben Masters (Julian) and Tracey Ross (Eve) have been dating for many years.
* WhatCouldHaveBeen: When Charity initially came back recast, she was scripted to have a final showdown with Tabitha with the ghosts of Grace and Faith to help her. But her recast was so unpopular with fans that the final battle was cancelled and this Charity was rewritten as a copycat.
** WordOfGod has also gone on record regarding the Luis/Sheridan/Antonio/Fancy story line. [[spoiler: Apparently if the show hadn't ended, Fancy was going to lose her child and then Luis and Sheridan would have an affair with each other, setting up a reunion and Antonio becoming a villain again.]]
** Apparently, the writers had an alternate idea with Sheridan after she turned evil that they never went with. [[spoiler: The idea was that "evil" Sheridan had actually been Beth all along, and the real Sheridan was once again being held captive.]]
