TheDexterprequel showDexter: Original Sinhas already changed quite a bit from Dexter Morgan’s (Patrick Gibson) early life and the timeline of his story.Original Sinhas clearly done its homework on the mainDexterseries and its accompanying sequel series,Dexter: New Blood. There have been several great Easter eggs and references in the prequel series, fromOriginal Sin’s Trinity Killer referenceto the possible Brian Moser sightings throughout the show. It hasn’t been completely faithful to the other shows, however, andOriginal Sin’s timelinehas made some major changes to the establishedDextercanon.
A certain number of small retcons and timeline inconsistencies were basically unavoidable forOriginal Sin. The mainDexterseries explored Dexter’s youth and early days as a serial killer to a surprising extent.Original Sinwould have had a nightmare of a time carving a completely novel story out of all the small reveals scattered throughoutDexter’s eight seasons. While some creative liberty was to be expected,Original Sinhas still made some fairly major changes toDexter’s timeline, and it’s created a few glaring plot holes for the original series andNew Blood. These 10 inconsistencies are the biggest in the prequel show.
10Dexter Should Still Be In College During Original Sin
Dexter’s Earliest Kills Happened While He Was In College & His 20-Year High School Reunion Was In 2011
The main problemOriginal Sinpresents to the timelineDexterestablished is that it’s set too early.Original Sinfollows Dexter just after he graduates from college in 1991, but the premiere ofDexterseason 6 saw Dexter attend his 20-year high school reunion in 2011.Dexter should have graduated from high school, not college, in 1991, yetOriginal Sinboth tweaked Dexter’s age and rushed him through college in order to graduate at age 20. It’s perhaps not the most important change, but it is fairly significant given how prominent Dexter’s high school reunion was inDexterseason 6.
If it had stuck to the original show’s timeline, Dexter would have been hunting down drug dealers and co-ed murderers instead of loan sharks and serial killers.
The main way Dexter’s age changes things forOriginal Sinis through his victims.Dexteralluded to the idea that Dexter was killing people all throughout his college career, yetOriginal Sinestablished that he only took his first victim a week before he graduated. The forgottenwebseriesDexter: Early Cutseven established that Dexter killed one of his college professors and one of his classmates. If it had stuck to the original show’s timeline, Dexter would have been hunting down drug dealers and co-ed murderers instead of loan sharks and serial killers.
9Debra Morgan Should Be A Lot Younger Than Dexter In Original Sin
Dexter Made Debra Seem Much Younger Than Original Sin Made Her
Dexter wasn’t the only member of the Morgan family whose age was changed inOriginal Sin. Debra Morgan’s (Molly Brown) age actually changed even more than Dexter’s did. InDexterseason 1, Deb was presented as a rookie cop making her way up through vice and into homicide, while Dexter was 35 years old and an established figure at Miami Metro.Dexterseason 8 even confirmed that Deb was born eight years after Dexter, yetOriginal Sinis presenting her as just four years younger; Dexter is 20 and Deb is 17. With that age gap, Debra would have been 31 when she first got transferred to homicide.
None ofDexter: Original Sin’s retcons, timeline inconsistencies, or plot holes necessarily make it a bad prequel.
The difference in Dexter and Deb’s age gap also changes their sibling dynamic significantly. In the original show, Dexter seemed to have taken care of Debra to an extent, especially after Harry’s death. InOriginal Sin, however, Debra seems to be much more independent, and she even takes care of Dexter in some ways. Deb’s responsible for making dinner, she babysat him after he accidentally got high, and she’s even encouraging him to be more social.Deb inOriginal Sinis almost unrecognizable from the shy and self-conscious Deb who had to ask her big brother for help several times inDexterseason 1.
8Original Sin Changed Dexter’s Third Kill
Dexter’s Third Kill Was Originally A Drug Dealer, Not Levi Reed
Dexter’s first six kills were revealed in some ofDexter’s flashbacks andEarly Cuts' episodes, yetOriginal Sinchanged them as well. One in particular, Dexter’s third kill, was especially different in the prequel show.InDexterseason 8, Harry Morgan (James Remar) revealed that Dexter’s third kill was an unidentified drug dealer, but he also mentioned that it was the first time Dexter displayed photos of his victims.Original Sin, however, made Dexter’s third kill Levi Reed (Jeff Daniel Phillips), a child murderer who did not deal drugs. Harry also revealed that in a confidential meeting with psychiatrist Evelyn Vogel, so he had no reason to lie.
Dexter: Original Sin Retcons The Kill That Officially Made Dexter Morgan A Serial Killer
Dexter: Original Sin saw Dexter officially become a serial killer, but it also introduced a major retcon to the moment and a twist in Dexter season 8.
There’s no way to reconcileOriginal SinandDexteron this particular issue: it’s an outright contradiction of something the latter established very explicitly.Switching from an unnamed drug dealer to Levi Reed both madeOriginal Sinmore original and let it dive deeper into Harry’s decision to use Dexter as a weapon for justice, but it changed the main series to do so. It was probably for the best, as Levi Reed’s death was a great moment inOriginal Sin, but even a good retcon is still a retcon.
7Original Sin Completely Ignored Dr. Vogel From Dexter Season 8
Harry Morgan Was Supposed To Go To Dr. Vogel For Advice About Dexter’s Early Kills
Original Sindidn’t limit its retcons ofDexterseason 8 to his victims, however. Dr. Evelyn Vogel (Charlotte Rampling) has also been written out of Dexter’s early life as a serial killer entirely.Dexterseason 8 revealed that Vogel helped Harry come up with theCode of Harry, and that the two met frequently as Dexter started killing people. They made tapes shortly after several of Dexter’s earliest kills, like after he killed his third victim.Original Sinshould include scenes of Harry discussing Dexter’s kills with Vogel, but it has yet to even introduce her to the show.
Other than Harry himself, Dr. Vogel had the biggest impact on Dexter’s early life and development out of anybody in theDexterfranchise. It was because of Vogel’s advice that Harry kept training Dexter as a serial killer, even despite his reservations.By removing Dr. Vogel,Original Sinis putting more of the responsibility for Dexter’s violence on Harry, and making him even more guilty for using Dexter as a tool for murder by proxy. Without Vogel, Harry will also have no one else to turn to when he discovers just how heinous Dexter’s killing method is, which will make his eventual suicide even easier to believe.
6Harry Morgan Slept With Other CIs Besides Laura Moser
Original Sin Makes Laura & Harry’s Relationship Seem Like A Momentary Lapse Of Judgement
Original Sinhas done quite a bit to make Laura Moser’s (Brittany Allen) story more fleshed out, but it had to changeDexterto do so.InDexterseason 2, Deb learned that Harry had a long list of criminal informants that he slept with, and one of them even suggested Harry picked his CIs specifically because he wanted to have a sexual relationship with them.Original Sinseems to have changed that, however, as Harry’s relationship with Laura is being portrayed as an unintentional bout of passion and weakness, rather than part of a larger pattern of adultery.
Making Harry and Laura into star-crossed lovers helpedOriginal Sinquite a bit.Laura feels much more fleshed out, and the show’s flashbacks have added even more moral grayness to Harry as he continues to force the woman who loves him to conduct dangerous work as a criminal informant. It also, however, detracts from the moral grayness the original show gave Harry by revealing he was a serial cheater and womanizer. It also somewhat excuses Harry’s affair by showing that his romp with Laura was a response to his marital problems with Doris (Jasper Lewis).
Harry’s Original Partner Was Davey Sanchez, Not Bobby Watt
One of the more blatant changesOriginal Sinhas made toDexter’s lore concerns Harry’s partner. InOriginal Sin, Harry has been working with Bobby Watt (Reno Wilson) since the 1970s. However, in the originalDexter, Harry’s partner was named Davey Sanchez. Despite not appearing on-screen, he was actually a very important character.Davey was murdered by a man named Juan Ryness, and Harry walked in on Dexter taking revenge against Ryness. Seeing one of Dexter’s mutilated corpses first hand was one of the main reasons Harry ended up taking his own life.
While Bobby Watt does directly contradictDexter’s description of Davey Sanchez, it’s not actually as important of a retcon as other changes.Original Sincould still stay true to the most important part of Davey’s story by eventually having Bobby killed, and having his murderer walk free. Thus, Harry would have Dexter kill the murderer, setting off a domino effect that causes Harry to commit suicide. At this point,Original Sinhas effectively only changed the name of Harry’s partner, and it could easily stay true toDexterlore.
4Captain Matthews Should Already Be At Miami Metro Homicide
Another ofOriginal Sin’s changes affects a different character from the mainDexterseries. InOriginal Sin, Captain Aaron Spencer (Patrick Dempsey) is in charge of Miami Metro’s homicide division, and it seems he’s had the job for quite a long time. Spencer and Harry are good friends, and they have quite a history together.Harry also had a close relationship with a different police captain inDexter, however; Captain Thomas Matthews (Geoff Pierson). In the early 1990s, it should be Matthews leading Miami Metro inOriginal Sin, not Spencer.
How Harry Morgan Dies In Dexter & When It Will Happen In Original Sin
It’s already a given that Christian Slater’s Harry Morgan will die in Dexter: Original Sin, but the show has a big decision to make with its timing.
Dexterheavily implied that Harry and Matthews had a good and long-standing friendship with one another.One flashback saw Matthews visit the Morgan family household on Deb’s birthday, and he was good enough friends with Harry to hide his official cause of death in his autopsy to protect Deb and Dexter. That type of friendship takes years to foster, but it currently looks like Harry and Matthews only knew each other for a short time inOriginal Sin. Even ifOriginal Sinbrings Matthews in to replace Spencer, there shouldn’t be enough time before Harry’s death for them to grow that close.
3Dexter Shouldn’t Be Working With Harry At Miami Metro In Original Sin
Harry Originally Died When Dexter Was Still In College, So They Shouldn’t Have Experience Working Together
Perhaps one of the broadest timeline inconsistencies inOriginal Sinis the mere fact that Dexter and Harry are working together at all. In the original show, Harry died while Dexter was still in college, long before they could have been coworkers.Dextereven used that fact on several occasions, as both Dexter and Deb had to go to Captain Matthews to get information about Harry’s time at Miami Metro. Now thatOriginal Sinshowed that Dexter worked side by side with his dad, however, he should have at least some firsthand knowledge of Harry’s career, or at least a better friend to ask than Matthews.
Both Angel Batista (James Martinez) and Maria LaGuerta (Christina Milian) should have started their detective careers years after Harry died.
Dexter isn’t the only character who shouldn’t be working with Harry Morgan inOriginal Sin, though. Both Angel Batista (James Martinez) and Maria LaGuerta (Christina Milian) should have started their detective careers years after Harry died.Neither of them ever made reference to personally knowing and working with Harry, even though Maria was his partner on the NHI Killer case. Dexter also wondered how he had grown so close to Batista inDexterseason 1, even thoughOriginal Sin’s new timeline means that they had been coworkers for 15 years and Dexter was the son of Batista’s late friend.
2Dexter: Original Sin Undid New Blood’s M99/Ketamine Retcon
Dexter Used M99, New Blood Changed It To Ketamine, & Original Sin Changed It Back
One ofOriginal Sin’s most unusual retcons didn’t actually change the originalDexter. In fact, the franchise reverted to the main series' canon afterDexter: New Bloodchanged it in 2021.New Bloodinfamously changed Dexter’s drugof choice from the horse tranquilizer M99 to the common sedative ketamine.It was a controversial decision that many fans ofNew Bloodsaw as an overly convenient plot contrivance, butOriginal Sinswitched back to the original drug. A large portion ofOriginal Sinepisode 5was even dedicated to showing how Dexter got his hands on M99, not ketamine.
Dexter Just Ignored New Blood’s Most Divisive Plot Hole 3 Years Later
Dexter: Original Sin got a chance to fix a plot hole that Dexter: New Blood created three years ago, and the prequel show ended up ignoring it.
Though it reestablished the status quo of Dexter’s go-to sedative,Original Sin’s choice of M99 over ketamine madeNew Blood’s decision to use the latter even more confusing. IfOriginal Sinhad doubled down on ketamine, thenNew Bloodwould have been a simple - albeit controversial - retcon.By changing back to M99, however,New Blood’s use of ketamine is now completely unexplained. Angela (Julia Jones) seemingly found out Dexter was the Bay Harbor Butcher through sheer luck and some internet blogs that got key facts of the case wrong, asOriginal Sinproved that he never used ketamine at all.
Despite Harry’s Advice About Trophies, Dexter Still Went On To Take Blood Slides
He hasn’t started taking blood slides yet, but Dexter did take a trophy already inOriginal Sin. In a bit of foreshadowing to his eventual use of blood slides,Original Sinsaw Dexter take Nurse Mary’s earrings as a trophy from his first kill. That led to a slew of problems that eventually culminated in Harry explaining why trophies create a direct line of evidence back to Dexter and how it violates the first rule of the Code: don’t get caught.Despite Harry giving him an explicit warning not to take trophies, Dexter would still go on to take blood slides by the time of the main series.

Throughout the original series, Dexter treated the Code of Harry like law. There were, of course, a fewkills that violated the Code of Harry, but those were during moments where Dexter was either mistaken or going through an internal turmoil.Dexter’s decision to take blood slides directly and willfully contradicted the Code of Harry, and the fact thatOriginal Sinhad Harry expressly warn Dexter about it makes it an even more egregious rule break. On its own, Harry’s warning isn’t much of a plot hole, but it adds up withDexter: Original Sin’s other inconsistencies.
