History Series / LockeAndKey2020

* AdaptedOut: A few so far:
** Al Grubb, Sam's friend and Nina's rapist in the comics.
** Jamal Saturday, Scot's best friend and Kinsey's boyfriend.
** Jordan Gates, Tyler's romantic interest.
** The Giant Key is not included in the show.
* AdaptationExplanationExtrication:
** It's revealed in the comics that the reason why adults can't perceive or memorize magic is because Hans Riffel deliberately altered Keyhouse to that end in 1942, having seen the devastating results of ambitious adults trying to harness the magic of the Keys. In the show, it's portrayed as an intrinsically magical element with no real explanation for the arbitrary deadline.
** In the comics, it's explained that Dodge's nature as an Echo allowed him to extend his consciousness into empty places while still trapped in the Well, hence why he was able to communicate with Sam long distance - as Sam's ''soul'' is empty and purposeless. In the show, it's never explained how Dodge managed to communicate with Sam via the Wellhouse painting in Rendell's office or why this is never used again.

** In the comics, the Head Key allowed the wielder to literally open their skull, granting them access to a miniature MentalWorld that they could reach into and alter at will. The show expands on its power by simply creating a door into the mental world large enough for the wielder to enter and explore.
*** On a similar note, the manifested emotions and memories accessed with the Head Key are - in the comics - tiny and easily contained in a bottle. In the show, they're full-sized and can be extremely dangerous to anyone in their path, as is the case with Kinsey's Fear, and [[spoiler: Eden's MurderousMannequin army.]]

* BigBadDuumvirate: [[spoiler: The first season ending sets one up with Gabe, who is really Dodge/Lucas, and Eden, who was possessed by a demon from the Black Door.]]

* BreakingTheFellowship: After almost drowning in the Drowning Caves, the Savini Squad breaks their friendship with Kinsey and Gabe. [[spoiler: They reconsider.]]

* ButtMonkey: Kinsey, Scot and Gabe use the Music Box key on Eden to embarrass her.

** The Demon Key: [[spoiler: A key Doge forces Duncan to forge that allows people to be [[DemonicPossession possessed]] by a demon]].

* CoolOldGuy: Joe Ridgeway, an English teach at the Locke's school, and [[spoiler:the ghost of Chamberlain Locke.]]

* DemonicPossession: [[spoiler:Lucas is possessed by one of the demonic "bullets" that emerge from the Black Door.]]

* TheHedonist: Dodge. She eats a lot, indulges in stealing clothes and jewelry from museums, simply to change her look, takes enjoyment with very high class living conditions and [[spoiler:engages with a hapless bystander with an offer of sex with the intent to kill them. As Gabe though, he is much more reserved]]

* HeKnowsTooMuch: [[spoiler: Joe Ridgeway saw Lucas with Ellie Whedon at her house and took a picture of him. Lucas kills him to continue operating in secret.]]

* KilledOffForReal: [[spoiler:Sam is stabbed by Dodge and falls out the Ghost Key door, separating his soul from his body. The police arrive, taking Sam's dead body away and closing the door, trapping Sam as a ghost.]]

* LeftHanging: Some season 1 mysteries are left unresolved, to be resolved in later storylines:
** How did Erin Voss become trapped in her own mind?
** What happened to Kinsey's fear entity?
*** [[spoiler:Eden and Gabe trapped Kinsey's fear in a cage and keep it as a pet. Later on it escapes and is absorbed by Kinsey.]]
** [[spoiler:Sam, while technically dead, still exists as a ghost.]]
*** [[spoiler:He reappears working with Chamberlain Locke trying to stop Dodge. He later helps Kinsey find the Angel Key.]]

* LovableAlphaBitch: Eden Hawkins was initially the standard AlphaBitch, a [[ThePrimaDonna PrimaDonna]] who edged out Kinsey out of spite. But while she can be vain and intimidating, she is not really malicious and [[HeelRealization expresses discomfort when she learns what Kinsey thinks of her]]. It surprisingly doesn't take much for her to become an ally, especially after learning about the magic keys. She also helps [[spoiler:the Locke children dispose of Dodge by trapping her behind the Black Door.]]

* MindRape: Erin Voss went through a form of this, leaving her in a near catatonic stupor. [[spoiler:Somehow her Head Key self, of high school age, was imprisoned in her mind. It's implied in Lucas' initial attack she suffered severe brain damage]].

* NotQuiteDead: Kinsey stabbed and buried her "fear" only [[spoiler:for it to be alive later on. This is because [[FridgeBrilliance emotions can't be killed, only buried]].]]

* OurGhostsAreDifferent: Echoes created via the Echo Key are dead echoes of people. They are not really alive and can't be killed in traditional ways. They learn that demons that possessed human hosts are bonded to their spirit, and will return with them as echoes.

* PragmaticAdaptation: Season 1 of the series adapts the comic's first three story arcs "Welcome to Lovecraft", "Headgames" and "Crown of Shadows", along with elements introduced in later arcs, while expanding on the Lockes' home and school lives.

* TheReveal: [[spoiler: Gabe was Dodge all along, the person they threw behind the Black Door was actually Ellie and Eden was hit with one of the glowing bullets and is now possessed. Season 2 emphasizes that Gabe never truly existed as the key can't turn anyone into a real person but a made-up persona.]]
** [[spoiler: Before this, Erin Voss revealed to Kinsey that Dodge and Lucas, who died 25 years earlier, were the same person.]]

* ShapeshifterDefaultForm: Played with. We are introduced to the "Well Lady" at first as an attractive, dark haired woman (played by Laysla De Oliveira) and is given the name Dodge. As it turns out, Dodge was a known persona for [[spoiler: Lucas via the Identity Key]], which Erin Voss shares with the kids and becomes the first step to unraveling what is happening. Dodge is basically the standard appearance for this enemy of the first season, as [[spoiler: fooling the kids into throwing that persona into the Black Door]] means that they end up taking a new standard form in [[spoiler: Gabe]] in the second season.
* ShootTheShaggyDog:
** [[spoiler: Ellie Whedon was already TheWoobie. Her boyfriend was possessed by a demon, killed two of their friends and was killed by another one. For years she felt something was missing until she used the Echo Key to bring Lucas back. This led to her being emotionally manipulated and physically abused until she had enough and tried to fight back, only to fail. Lucas used her as part of his plan, using the Identity Key to make Ellie look like Dodge and making the Locke children and friends think they really defeated Dodge. The children ended up throwing Dodge, really Ellie, [[FateWorseThanDeath screaming into the void behind the Black Door forever]].]]
** [[spoiler:Early in Season 2, while seeking information from Erin's mind, Tyler and Kinsey learn that she was accidentally imprisoned inside her own head over two decades earlier, and set her free. While she's upset at having lost so much time, she has every intention to make up for it, and is soon making plans for her future -- only to be brutally murdered by Gabe just a few days later.]]

* SuperStrength: Lucas/Dodge, as a result of the demonic possession, has enhanced strength.

* SurprisinglyRealisticOutcome: After being introduced to the Head Key and discovering a monstrous manifestation of her fears and insecurities, Kinsey decides to go back inside her head, "kill" the entity, take it into the real world and bury it. The next day she starts acting more carefree and outgoing, but saying and doing things that are unkind, even cruel because her sense of restraint and empathy became disconnected. The entity turns out to not be dead and attacks Eden, someone Kinsey fears. She realizes [[LiteralMetaphor that "burying" her emotions]] was not improving things and was only causing further problems for herself and those around her. She later brought the fear entity back inside her head, as it was better to deal with her feelings one step at a time in a mundane fashion.

* TroublingUnchildlikeBehavior: Sam Lesser veers off into this. Him killing Rendell Locke, [[spoiler:his own father and attacking the Locke family twice qualifies as this.]] Though because of his abusive father and manipulations by Dodge, he was also DrivenToVillainy.

* UnwittingInstigatorOfDoom: Bode didn't know giving Dodge the Anywhere Key would result with so much death.

* UnexplainedRecovery: [[spoiler:Ellie Whedon returns after a near cave in opens the Black Door. How she survived for so many months, let alone not possessed by a demon, is not explained.]]
* WeaksauceWeakness: The shadows created by the Crown of Shadows can be defeated by light from the smallest light source, like a match.

* WeCanRuleTogether: [[spoiler: Once Gabe has the Demon Key he starts making numerous lackey's who are obedient to his commands, but despite not needing her permission he still wants to convince Kinsey to willingly become possessed]].
* WeirdnessCensor: One that is magically enforced. Adults who experience the magic of the keys will forget its existence within a few seconds, though they might be curious about the physical evidence left behind. The kids learn of the Memory Key that is designed to allow adults to retain memories of the magic.
** There do seem to be some natural exceptions however. Rufus, due to his particular disorder giving him a more child-like personality, despite being in his early twenties can freely talk about and remember the keys and magic, including remembering seeing two Dodges even while concussed and half conscious. While not remembering initially, he is able to recall after some help from his therapist. A feat that shouldn't have been remotely possible if he was indeed able to be affected by the memory altering.

* YouHaveOutlivedYourUsefulness: [[spoiler:Sam for Dodge, who stabs and kills him.]]

* YourMindMakesItReal: Thanks to the Head Key, anything taken out literally becomes real in the physical world.

** The Chain Key: When used with the Great Lock, [[WhipItGood it creates a chain that can attack or restrain any target the wielder wants]].

* AmbiguousDisorder: Rufus seems to have some developmental problems, sports childlike vocal patterns and a hyperfocus on certain topics, though his tendencies are not nearly as pronounced as they were in the comic. It's worth noting that the actor is autistic.
** Sam Lesser has obvious psychopathic behaviors, but a flashback in high school shows him as very socially awkward, hinted as [[AbusiveParents a result of a bad home life]]. [[spoiler: Using the head key on him gives him a MyGodWhatHaveIDone response, implying deep down he wasn't in control of himself]].
** Erin Voss is in a psychiatric hospital in a mostly catatonic state. It's never explained exactly what is wrong with her, but implied to be from head trauma. [[spoiler: Turns out that she accidentally got trapped inside her own mind while using the Head Key, leaving her body catatonic.]]

** Revealed during the Revolutionary War flashback that British Captain Frederick Gideon willingly let himself be possessed, after seeing one of his soldier's possessed and the power it gave him.

* HeelFaceTurn: [[spoiler:Sam Lesser as a ghost helps the Lockes stop Dodge by leading Kinsey to the Angel Key. He later hijacks the body of one of Gideons enforcers and helps them escape and head off Gideons attempt to recover the Creation Key]].

* InvisibleToAdults: Adults are not capable of remembering the effect of the magic keys. Even if they see and experience it firsthand, they magically forget their experiences a few seconds after seeing it. [[spoiler:Subverted with Rendell, Ellie, and Mark, who somehow figured out a way to keep their memories of the keys into adulthood.]]

** [[spoiler:Under Rendall's instructions, Duncan forges The Memory Key specifically to combat this trope. This is how Rendall, Ellie, Mark and Erin all remember magic.]]

* OnlyTheChosenMayWield: On a minor level, the Locke kids seem to have a biometric pass to use the keys they find around the house, but Dodge is unable to take a key without it being willingly given by them. The Locke's initially think this is applicable to everyone, but learn it only applies to demons from the black door. A regular person can steal a key, and thereby Dodge is free to take it from ''them''. Dodge describes it as the keys being loyal to the Lockes. [[spoiler: Gideon calls forth echoes of former soldiers who are not possessed by a demon in order to get around it]].

* AdaptationalAlternateEnding: In the original comic books, [[spoiler: the story ends with Dodge being defeated, Lucas Caravaggio's soul being put to rest, though at the cost of Keyhouse burning to the ground; worse still, several of the Locke family's friends and loved ones are killed, resulting in much grief. However, Tyler keeps the surviving Keys and eventually goes on to rebuild the house with the power of Whispering Iron.]] In the show, [[spoiler: Gideon is defeated, Keyhouse survives, and only two minor characters die - but the Keys have to be sacrificed in order to close the rift that Gideon opened... but it's also indicated that there might be Keys left unaccounted for in the house.]]

* LaserGuidedAmnesia: Memories of the Key Magic will fade in adults a few moments after being exposed to it. This generally enforced AdultsAreUseless while simultaneously [[WeirdnessCensor cleaning up loose ends of anyone else catching bizarre events]]. The second season ends up deconstructing this. Duncan had memories of tragic events removed using the Head Key in addition to the Key Magic amnesia, which left him with large gaps of his childhood he doesn't remember. This made him very apathetic, sometimes hostile regarding his childhood and he doesn't know why. [[spoiler: Restoring his memories while still having Key Magic amnesia left him extremely disoriented as he couldn't make sense of the tragedy without further context, and the kids had to locate the Memory Key to fix this]]. Nina probably deals the worst with this. Since Rendell's death, Joe Ridgeway's death and Sam's involvement is all connected to the Key Magic, the kids have found some sense of closure by unraveling that mystery. But since Nina can't remember any of that, she feels like her family is moving on with their lives and can't understand how.

* TheCameo: Both Creator/JoeHill and Creator/GabrielRodriguez cameo as paramedics. Creator/TomSavini also cameos as the locksmith Bode goes to.

* TailorMadePrison: A number of side effects from the keys can be used as fairly effect prisons. Using the Head Key things have been stored inside their own mind. The Mirror Key creates a never ending labyrinth past a mirror threshold that is near impossible to escape on your own even with the key inserted. The Snow Key accesses a snowglobe, which was used to trap a couple of human-possessed demons long ago.

** The Mending Key: a key that, when used alongside a cabinet, can repair ''anything'' put inside of it. Within reason.

** [[spoiler: The Omega Key: the key that opens the Black Door.]]

** [[spoiler: The Demon Key: a key that allows people to be [[DemonicPossession possessed]] by a demon]].

** [[spoiler: The Alpha Key: a key that kills demons inside human hosts but also kills the hosts as a side effect of the demon liquifying and solidifying in the host]].
** [[spoiler:[[PowerGivesYouWings The Angel Key]]: a key that needs to connect to a harness that allows its user to gain wings to fly]].
** [[{{Animorphism}} The Animal Key]]: a key that turns the user into an animal. Each user has a specific animal they turn into; Bode turns into a sparrow, Kinsey turns into a cat, and Ellie mentions turning into an owl.
** The Snowglobe Key: transports people into a snowglobe containing a miniature Key House when used inside the house.
** [[TimeTravel The Timeshift Key]]: a key that sends the user back in time for a specific amount of time; however, anyone who is interacted with in the past won't remember it, and [[spoiler:anything or anyone that is brought forward in time will disappear after the timer inside the clock the key is used with runs out in order to prevent a paradox from happening]].

* HeelFaceTurn: [[spoiler:Sam Lesser as a ghost helps the Lockes stop Dodge by leading Kinsey to the Angel Key.]]

* OnlyTheChosenMayWield: On a minor level, the Locke kids seem to have a biometric pass to use the keys they find around the house, but Dodge is unable to take a key without it being willingly given by them. The Locke's initially think this is applicable to everyone, but learn it only applies to demons from the black door. A regular person can steal a key, and thereby Dodge is free to take it from ''them''. Dodge describes it as the keys being loyal to the Lockes.

* AdaptationInducedPlotHole:
** Chamberlin Locke's ghost is not haunting the grounds in the comics, so there's nobody who the heroes can consult on the history of the family and the many dangers of the Keys. In the show, however, Chamberlin's potential for advice is almost never used - the most prominent exception to this being in season 2, when ''Dodge'' is willing to consult him for help.
** In the show, Sam Lesser's attack on Keyhouse is rescheduled until ''after'' Dodge escapes from the Wellhouse and more Keys are discovered... but the overall script remains the same - meaning that the Lockes apparently [[ForgottenPhlebotinum don't think to use the Music Box to stop Sam]].
*** On a similar note, the show features Sam somehow making it from the prison to Keyhouse with astonishing speed despite not possessing the Anywhere Key, and somehow never being noticed by anyone in the meantime - despite burning down a good chunk of the prison with the Matchstick Key; in the comics, his journey takes several ''days'' of hitchhiking, during which he murders several people who he fears might have recognized him.
*** Also, the ''reason'' for Sam's attack on Keyhouse. Again, in the comics, the attack happened before Dodge escaped the Wellhouse; indeed, Dodge didn't just want to take another shot at finding the Omega Key, but actually intended to use the attack as a means of tricking Bode into handing over the Anywhere Key... but here, Dodge is already free and has access to the Identity Key, which can allow them to take on any number of personas that could theoretically trick the Lockes into handing over the Keys (as they do ''later in the show''). More to the point, Dodge is indestructible and super-strong, whereas Sam is an ordinary human with one Key, so there's no explanation for why they bother breaking the guy out jail and sending him to Keyhouse when - unlike the comics - Dodge has ''tons'' of other options.
** In the show, Kinsey, Tyler, and their assorted friends don't seem terribly worried about Kinsey's manifested Fear running loose - and actually leave it for another season before dealing with it. In the comics, this relaxed attitude was due to the extracted personality elements being small enough to fit in a bottle; in the ''show,'' these elements are human-sized and are capable of inflicting physical harm - as [[ButtMonkey Eden has already found out the hard way]] - making Kinsey and co come across as both stupid and deeply callous.
** In the comics, Rendell Locke set out to open the Black Door because he was worried about forgetting magic when he turned eighteen and wanted Whispering Iron to create the Memory Key; plus, because he was aware of the dangers involved thanks to the Timeshift Key, he and his friends took as many precautions as possible, ''including'' full use of the Keys they had obtained, and things only went wrong because [[spoiler: Duncan made the mistake of following them into the cave, accidentally getting Lucas possessed while trying to save Duncan from the Door.]] In the show, the Memory Key isn't considered until after this escapade: Rendell was just curious about what was behind the Black Door and went in completely cluelessly, making him come across as reckless and stupid.
** In the comics, Rendell and his surviving friends never created the Memory Key thanks to [[MyGodWhatHaveIDone their remorse over all the deaths they unwittingly caused]], instead opting to forget magic - hence why nobody knows what happened to Erin and why she remains in her sorry state for so long. In the show, Rendell and his friends successfully created and used the Memory Key to preserve their knowledge of magic... but even though they ''would'' be able to understand and recognize what had happened to Erin, none of them ever heard anything about it or did anything to help her - not even Ellie, ''who was living in the same town as her at the time and never left.''
** Erin's catatonia. In the comics, [[spoiler: it's due to Dodge using the Head Key to literally empty her mind]]; in the show, [[spoiler: it's due to her being accidentally trapped inside her own MentalWorld when a maid at Keyhouse removed the key from her head... naturally raising the question of why Erin would have been stupid enough to use the Key with her body alone and unguarded - and why none of the Keepers of the Keys ever tried to help]].
** Ellie Whedon's comic incarnation summons Dodge from the Wellhouse as a result of being {{Mind Rape}}d by a fragment of Dodge, and originally came to Keyhouse to murder her abusive mother - which she couldn't do, but [[BadGuysDoTheDirtyWork Dodge could]]. In the show, the fragment and the abusive mother don't exist... so instead, Ellie summoned Dodge of her own accord, even allowing them into her house after Dodge escaped, seemingly not understanding that this was the version of Dodge that was ''possessed by a demon '''until he murdered someone in front of her.''' '' In the comics, she at least had the excuse of being unable to remember the supernatural; her show incarnation has no such excuse.
** In the show, Ellie is forced into working for Dodge due to a direct threat against Rufus - despite the Lockes having enough of the Keys to theoretically keep Rufus safe - and doesn't confide in the Lockes until Rufus talks her into it, making her seem weak-willed and easily manipulated considering all the murders that Dodge has committed by this stage. In the comics, Ellie is being kept in line due to a mixture of guilt, psychological abuse, and outright MindRape via the Head Key, to the point that she isn't able to turn against Dodge because she honestly believes that he's actually her nephew.
*** For that matter, it's never specified why ''Rufus'' doesn't try anything against Dodge when he makes it clear that he doesn't like seeing his mother being forced to cooperate. In the comics, Rufus is a child no older than Bode, not to mention easily pushed around by menacing authority figures like Dodge and his own grandmother, so it makes sense that he can't do anything aggressive against the older, much more physically-imposing Dodge... but in the show, Rufus is a grown man and has already helped Bode booby-trap his bedroom, so he's not helpless - and yet he doesn't do anything more than encourage Ellie to break free from Dodge's control.
** It's never stated why Dodge chose to take the form of a woman, when the Identity Key could have allowed him to take the form of just about any human being imaginable, or why he chose to do so ''at the bottom of a Well,'' or even why Dodge ''continues'' to use this female form when using literally any other one would prompt less fear from Bode. In the comics, there ''is'' no Identity Key, the various shapeshifting powers being divided between the [[BlackLikeMe Skin Key]], the [[TimeMaster Tempus Fugit Key]], and the [[SexShifter Gender Key]] - which Dodge actually has access to... and far from using it in the Well for no good reason, Dodge used it before he was killed the first time in order to ShowSomeLeg and trick Mark Cho into letting his guard down. Because he was killed soon after while still female, Dodge's Echo remains in this form until he escapes.
*** Also, how Dodge got his hands on the Gender/Identity Key: in the comic books, Ellie accidentally dropped her Keys in the Wellhouse after her mom hit her in the face; then, when Dodge's freshly-summoned Echo [[KickTheSonOfABitch snapped Candice Whedon's neck]], Ellie fled without picking them up. In the show, Ellie's first meeting with Dodge was conducted quite peacefully with no murders, with Ellie still being totally clueless about the fact that Lucas's Echo was possessed, even when he began demanding the Keys, to the point that when asked, she just... hands over the Identity Key - which, unlike the Gender Key, offers ''literally '''unlimited''' '' opportunities for disguise.
** Late in season 1, Ellie reveals that most of the Keys were split between the surviving Keepers of the Keys and the rest were simply hidden around Keyhouse... but it's never once explained why they needed to be divided at all, or why they couldn't just be hidden - especially since the ones being protected by the Keepers were arguably the easiest for Dodge to find. More to the point, it's never explained why Mark needed to commit HeroicSuicide in order to keep Dodge from torturing the Key locations from him, since the Keepers have already removed Duncan's memories of the event and could easily do the same for Mark and the others. In the books, Rendell never needed to include any of these [[ComplexityAddiction overcomplicated contingencies]]: he just hid the Keys around Keyhouse by himself, leaving Rendell as the only one who knew all the secrets until he turned eighteen and forgot about magic - hence why Sam went after Rendell instead of any of the others.
** In both the comics and season 2 of the series, [[spoiler: a disembodied Sam Lesser]] attempts to kill Dodge by possessing his body, only to be thwarted and forced back out again. In the comics, Dodge is in ghost form and trying to negotiate with [[spoiler: Sam]] not far from the house and understands the risk of a GrandTheftMe, forcing [[spoiler: Sam]] to fight him to a standstill before he can get anywhere near Dodge's unconscious body. In the show, Dodge is negotiating with Chamberlin Locke in the graveyard on the far, ''far'' end of the property, leaving [[spoiler: Sam]] with ample opportunity to fly off and possess Dodge's body while he's still distracted... but for some reason, [[spoiler: Sam]] doesn't get moving until ''Chamberlin tells him to, '''alerting Dodge to the threat and wasting precious time.''' ''
*** Also, the attempted possession features [[spoiler: Sam]] trying to kill Dodge. In the comic books, this made perfect sense, as Echoes are still possessed of ordinary human weaknesses despite their supernatural nature. However, in the ''show,'' Echoes are effectively invincible and can only be killed by forcing them over the Wellhouse threshold - and yet the episode attempts to play this as if [[spoiler: Sam]] might actually have a chance to end Dodge's reign of terror once and for all, even though Dodge has already demonstrated his invincibility on camera back in season 1 by casually taking six bullets to the chest.
** In the show, the fact that the Keys cannot be stolen from the Lockes (by demons, at any rate) results in some confusion: despite being cautious enough around Jamie Bennet to check her for demons via the old "take this Key from me" test, Bode doesn't seem to find it suspicious that [[spoiler: Gabe]] feels the need to borrow the Ghost Key from him. In the books, no such rule exists, and Dodge can steal any of the Keys at any time - to the point that he's in the habit of pinching the Head Key from Kinsey and returning it before she realizes it's gone. Furthermore, in Dodge's Ghost Key incident, he didn't need to ask Bode for anything: he already ''had'' the Ghost Key and had snuck into Keyhouse in the dead of night to use it.
** In the "Clockworks" issue, the cave housing the Black Door was originally underwater up until Peter Locke pumped the water away and allowed the revolutionaries to store their provisions there; the Black Door itself was an actual carved door that almost immediately began luring in victims and couldn't be closed until Benjamin created the first Whispering Iron lock and the Omega Key. In season 2 of the show, it's revealed that the cavern was perfectly mundane and could be reached at low tide with no potential for demon attacks... up until Captain Gideon was forced to retreat in there, whereupon the wall cracked open to reveal the portal that would become the Black Door. No explanation for Gideon's miraculous discovery is ''' ''ever'' ''' provided.
*** On that note, the fact that [[spoiler: the demons can shoot out of the Black Door like bullets]] raises questions as to how anyone could have safely obtained Whispering Iron without casualties. In the comics, [[spoiler: the demons don't shoot out like bullets, and ''can't'' cross the threshold without immediately collapsing to the ground as Whispering Iron, and it's ''theoretically'' safe to harvest so long as you can ignore the mesmerizing effect of the Door; indeed, it's so safe that Lucas was the first case of possession on record following Harm Timmerman and his brother back in the eighteenth century.]]
** During the EnemyCivilWar between Dodge and [[spoiler: Eden]], Dodge uses the Crown of Shadows to bring down the roof of the caves down on top of her - unwittingly breaking the Black Door open and [[spoiler: giving Ellie a chance to escape.]] If this was possible with the Crown of Shadows alone, one might wonder why the hell Dodge even ''needed'' the Omega Key in the first place when brute force would have been enough, or why he chose to menace Keyhouse with the Crown back in season 1 when he could have gone straight to the caves with a few hostages and recruited an army. In the comics, '''this is categorically impossible''': if the Black Door is opened by any means other than the Omega Key, it will simply open onto an empty room, hence why Dodge never tried brute force.
** In season 3, [[spoiler: Bode's possession by Dodge. In the show, it's because "Zack" was able to improvise despite being unmasked as Dodge and managed to outsmart Tyler, Kinsey, and even Sam Lesser; in the show, it's because Bode decided to go back in time to gloat over Dodge's defeat... only for Dodge to follow him back to the present. Suffice it to say that there's still no explanation as to why Bode would do something so '' '''insanely''' '' reckless after going back in time once and clearly recognizing that people in the past can react to his presence - unlike the comic incarnation, which was based around IntangibleTimeTravel.]]

*** Also, the ''reason'' for Sam's attack on Keyhouse. Again, in the comics, the attack happened before Dodge escape, and Dodge actually intended to use it as a means of coercing Bode into handing over the Anywhere Key... but here, Dodge is already free and has access to the Identity Key, which can allow them to take on any number of personas that could theoretically trick the Lockes into handing over the Keys (as they do ''later in the show''). More to the point, Dodge is indestructible and super-strong, whereas Sam is an ordinary human with one Key, so there's no explanation for why they bother breaking the guy out jail and sending him to Keyhouse when - unlike the comics - Dodge has ''tons'' of other options.

** Late in season 1, Ellie reveals that most of the Keys were split between the surviving Keepers of the Keys and the rest were simply hidden around Keyhouse... but it's never once explained why they needed to be divided at all, or why they couldn't just be hidden - especially since the ones being protected by the Keys were arguably the easiest to find. More to the point, it's never explained why Mark needed to commit HeroicSuicide in order to keep Dodge from torturing the Key locations from him, since the Keepers have already removed Duncan's memories of the event and could easily do the same for Mark and the others. In the books, Rendell never needed to include any of these [[ComplexityAddiction overcomplicated contingencies]]: he just hid the Keys around Keyhouse by himself, leaving Rendell as the only one who knew all the secrets until he turned eighteen and forgot about magic - hence why Sam went after Rendell instead of any of the others.

** On a similar note, the show features Sam somehow making it from the prison to Keyhouse with astonishing speed despite not possessing the Anywhere Key, and somehow never being noticed by anyone in the meantime - despite burning down a good chunk of the prison with the Matchstick Key; in the comics, his journey takes several ''days'' of hitchhiking, during which he murders several people who he fears might have recognized him.

** It's never stated why Dodge chose to take the form of a woman, when the Identity Key could have allowed him to take the form of just about any human being imaginable, or why he chose to do so ''at the bottom of a Well,'' or even why Dodge ''continues'' to use this female form when using literally any other one would prompt less fear from Bode. In the comics, there ''is'' no Identity Key, the various shapeshifting powers being divided between the [[BlackLikeMe Skin Key]], the [[TimeMaster Tempus Fugit Key]], and the [[SexShifter Gender Key]] - which Dodge actually has access to... and far from using it used it in the Well for no good reason, Dodge used it before he was killed the first time in order to ShowSomeLeg and trick Mark Cho into letting his guard down. Because he was killed soon after, Dodge's Echo remains in this form until he escapes.

** In the show, Sam Lesser's attack on Keyhouse is rescheduled until ''after'' Dodge escapes from the Wellhouse and more Keys are discovered... but the overall script remains the same - meaning that the Lockes apparently don't think to use the Music Box to stop Sam.

** In the comics, Rendell and his surviving friends never created the Memory Key after the catastrophe that followed, instead opting to forget magic - hence why nobody knows what happened to Erin and why she remains in her sorry state for so long. In the show, Rendell and his friends successfully created and used the Memory Key to preserve their knowledge of magic... but even though they ''would'' be able to understand and recognize what had happened to Erin, none of them ever heard anything about it or did anything to help her - not even Ellie, ''who was living in the same town as her at the time and never left.''

** Late in season 1, Ellie reveals that most of the Keys were split between the surviving Keepers of the Keys and the rest were simply hidden around Keyhouse... but it's never once explained why they needed to be divided at all, or why they couldn't just be hidden wholesale - especially since the ones being protected by the Keys were arguably the easiest to find. More to the point, it's never explained why Mark needed to commit HeroicSuicide in order to keep Dodge from torturing the Key locations from him, since the Keepers have already removed Duncan's memories of the event and could easily do the same for Mark and the others. In the books, Rendell doesn't need to include any of these overcomplicated contingencies: he just hides the Keys around Keyhouse, and once they turn eighteen, the Keepers forget all about magic.

** During the EnemyCivilWar between Dodge and [[spoiler: Eden]], Dodge uses the Crown of Shadows to bring down the roof of the caves down on top of her - unwittingly breaking the Black Door open and [[spoiler: giving Ellie a chance to escape.]] If this was possible with the Crown of Shadows alone, one might wonder why the hell Dodge even '''needed'' the Omega Key in the first place when brute force would have been enough, or why he chose to menace Keyhouse with the Crown when he could have gone straight to the caves with a few hostages and recruited an army. In the comics, '''this is categorically impossible''': if the Black Door is opened by any means other than the Omega Key, it will simply open onto an empty room, hence why Dodge never tried brute force.

** In the show, Kinsey, Tyler, and their assorted friends don't seem terribly worried about Kinsey's manifested Fear running loose - and actually leave it for another season before dealing with it. In the comics, the casualness was due to the extracted personality elements being small enough to fit in a bottle; in the ''show,'' these elements are human-sized and are capable of inflicting physical harm - making Kinsey and co come across as both stupid and deeply callous.

** Ellie Whedon's comic incarnation summons Dodge from the Wellhouse as a result of being {{Mind Rape}}d by a fragment of Dodge, and originally came to Keyhouse to murder her abusive mother. In the show, the fragment and the abusive mother don't exist... so instead, Ellie summoned Dodge of her own accord, even allowing them into her house after Dodge escaped, seemingly not understanding that this was the version of Dodge that was ''possessed by a demon '''until he murdered someone in front of her.''' '' In the comics, she at least had the excuse of being unable to remember the supernatural; her show incarnation has no such excuse.

** It's revealed in the comics that the reason why adults can't perceive or memorize magic is because Hans Riffel deliberately altered Keyhouse to that end in 1942, having seen the devastating results of ambitious adults trying to harness the magic of the Keys. In the show, it's portrayed as an intrinsically magical element with no real explanation.

** In the "Clockworks" issue, the cave housing the Black Door was originally underwater up until Peter Locke pumped the water away and allowed the revolutionaries to store their provisions there; the Black Door itself was an actual carved door that almost immediately began luring in victims and couldn't be closed until Benjamin created the first Whispering Iron lock and the Omega Key. In season 2 of the show, it's just a cavern that can be reached at low tide with no potential for demon attacks... up until Captain Gideon was forced to retreat in there, whereupon the wall cracked open to reveal the portal that would become the Black Door. No explanation for Gideon's miraculous discovery is ever provided.
*** On that note, the fact that [[spoiler: the demons can shoot out of the Black Door like bullets]] raises questions as to how anyone could have safely obtained Whispering Iron without casualties. In the comics, [[spoiler: the demons don't shoot out like bullets, and ''can't'' cross the threshold without immediately collapsing to the ground as Whispering Iron, and it's ''theoretically'' safe to harvest so long as you can ignore the mesmerizing effect of the Door; indeed, it's so safe that Lucas was the first case of possession on record following Harm Timmerman and his brother back in the eighteenth century.]]

'' In the comics, she at least had the excuse of being unable to remember the supernatural; her show incarnation has no such excuse.

*** Also, the attempted possession features [[spoiler: Sam]] trying to kill Dodge. In the comic books, this made perfect sense, as Echoes are still possessed of ordinary human weaknesses despite their supernatural nature. However, in the ''show,'' Echoes are effectively invincible and can only be killed by forcing them over the Wellhouse threshold - and yet the episode attempts to play this as if [[spoiler: Sam]] might actually have a chance to end Dodge's reign of terror once and for all, even though Dodge has already demonstrated his invincibility on camera back in season 1.

** Chamberlin Locke's ghost is not haunting the grounds in the comics, so there's nobody who the heroes can consult on the history and dangers of the Locke family. In the show, however, Chamberlin's potential for advice is used only on occasion - most prominently by ''Dodge.''

*** On that note, Erin's catatonia. In the comics, [[spoiler: it's due to Dodge using the Head Key to literally empty her mind]]; in the show, [[spoiler: it's due to her being accidentally trapped inside her own MentalWorld when a maid at Keyhouse removed the key from her head... naturally raising the question of why Erin would have been stupid enough to use the Key with her body alone and unguarded - and why none of the Keepers of the Keys ever tried to help]].

** In both the comics and season 2 of the series, [[spoiler: a disembodied Sam Lesser]] attempts to kill Dodge by possessing his body, only to be thwarted and forced back out again. In the comics, Dodge is in ghost form and trying to negotiate with [[spoiler: Sam]] not far from the house and understands the risk of a GrandTheftMe, forcing [[spoiler: Sam]] to fight him to a standstill before he can get anywhere near Dodge's unconscious body. In the show, Dodge is negotiating with Chamberlin Locke some distance from the property, leaving [[spoiler: Sam]] with ample opportunity to fly off and possess Dodge's body while he's still distracted... but for some reason, [[spoiler: Sam]] doesn't get moving until ''Chamberlin tells him to, '''alerting Dodge to the threat and wasting precious time.'''

** In the comics, Rendell Locke set out to open the Black Door because he was worried about forgetting magic when he turned eighteen and wanted Whispering Iron to create the Memory Key; plus, because he was aware of the dangers involved, he and his friends took as many precautions as possible, ''including'' full use of the Keys they had obtained, and things only went wrong because [[spoiler: Duncan made the mistake of following them into the cave, accidentally getting Lucas possessed while trying to save him from the Door.]] In the show, the Memory Key isn't considered until after this escapade: Rendell was just curious about what was behind the Black Door and went in completely cluelessly, making him come across as reckless and stupid.

** In the comics, Rendell and his surviving friends never created the Memory Key after the catastrophe that followed its creation, instead opting to forget magic - hence why nobody knows what happened to Erin and why she remains in her sorry state for so long. In the show, Rendell and his friends successfully created and used the Memory Key to preserve their knowledge of magic... but even though they ''would'' be able to understand and recognize what had happened to Erin, none of them ever heard anything about it or did anything to help her - not even Ellie, ''who was living in the same town as her at the time.''

** In season 3, [[spoiler: Bode's possession by Dodge. In the show, it's because "Zack" was able to improvise despite being unmasked as Dodge and managed to outsmart Tyler, Kinsey, and even Sam Lesser; in the show, it's because Bode decided to go back in time to gloat over Dodge's defeat... only for Dodge to follow him back to the present. Suffice it to say that there's still no explanation as to why Bode would do something so insanely reckless after going back in time once and clearly recognizing that people in the past can react to his presence - unlike the comic incarnation, which was based around IntangibleTimeTravel.]]

* LighterAndSofter: The adaptation is significantly more family-friendly than the comic book it is based on, for while it occasionally leans into BlackComedy and features some grisly murders, the tone is significantly lighter: the demons are not the Lovecraftian Children of Leng; racism, homophobia, and sexual assault are not featured; the sympathetic elements of the villains are more pronounced; and, of course, there are far fewer deaths by the end of the series.

* RaceLift: The series version of Erin Voss is white and Ellie Whedon is black.

** The shadows created by the Crown of Shadows are quite varied in the comics, taking the form of Roman legionnaires, samurai, wolves, bears, mythological creatures, and many other shapes. In the show, they're limited to scuttling humanoid forms.
