WARNING! This article contains SPOILERS for Dexter: Original Sin season 1, episode 1!Though Dexter Morgan tragically died inDexter: New Blood’s ending,the vigilante serial killer’s death is officially retconnedinDexter: Original Sin’s opening scene. Based on the hit novel series by Jeff Lindsay, the dark dramaDexterquickly became a success following its premiere in 2006, following Dexter Morgan across eight seasons as he evaded capture while acting as a vigilante serial killer. However, the originalDexterseries became notorious for its divisive endingin 2013, which saw Dexter mercy kill his sister Deb, abandon his son, drive his boat into a storm, and become a lumberjack under a new alias.
Given the show’s enduring popularity,Dexterwas given another chance to redeem its finale through a limited revival series in 2021, titledNew Blood. Dexter begins killing again after a nearly decade-long hiatus, coinciding with his estranged son, Harrison, finding him under his new identity in New York. InNew Blood’s ending, Harrison discovers that Dexter murdered an innocent man outside the Code.

However, the opening scene of the prequel,Dexter: Original Sin, reveals that Dexter actually survived.

Dexter Was Rushed To The Hospital & Revived After New Blood
The first few minutes ofDexter: Original Sin, a prequel taking the timelineback to 20-year-old Dexter’s first kills and beginnings at Miami Metro in 1991, take place in the present day. With narration by Michael C. Hall, who portrayed Dexter Morgan inDexter,New Blood, and the upcoming sequelResurrection,Original Sin’s opening scenepicks up exactly whereNew Bloodleft off with Dexter Morgan bleeding out in the snow. However,Original Sinreveals there’s more to that scene thatNew Blooddidn’t include.
InDexter: Original Sin’s opening, a gravely wounded Dexter is rushed to the hospital in an Iron Lake police car, with a team of doctors working tirelessly to revive him. While his pulse was almost lost,the emergency room team was able to successfully jump Dexter back to life, confirming that he wasn’t killed by Harrison’s gunshot. However, it’s likely that Harrison still thinks he killed his father, asNew Blood’s ending saw Harrison drive away across the country after Angela let him leave the crime scene.

She brought him to the hospital and ultimately saved Harrison from being a killer.
SinceOriginal Sinshows Dexter being driven to the hospital in a police car, it’simplied that Angela Bishop, Dexter’s ex-girlfriend and the Chief of Police in Iron Lake, rushed him there. In the final moments ofDexter: New Blood, Angela manipulated the crime scene to make it look like she was the one who shot him, not Harrison, and called in the incident as an “officer-involved shooting.”Original Sinnow indicates that Angela had some hope for Dexter’s survival after that moment, so she brought him to the hospital and ultimatelysaved Harrison from being a killer.

Dexter’s New Sequel Admits A Harsh Truth About New Blood, 2 Years Later
Dexter: New Blood continued the events of the original show, but now that the franchise is set to expand again, the sequel show reveals a weakness.
Dexterarguably wrote itself into a corner in 2006 by naming the series after the titular character; it’s analmost impossible task to continue the franchise without Dexter Morgan himself being in the lead. Plus, it’s nearly just as difficult to do so without Michael C. Hall being involved either on-screen or through voicework. Unless he becomes Harrison’s Dark Passenger, a la Harry Morgan for Dexter himself, then you’re able to’t continue if Dexter Morgan is dead. However, considering how divisive the character became inNew Blood, it would be amajor risk to carry aDexterspinoff on Harrison’s back.

Dexter: Resurrectionis set to premiere on Paramount+ with Showtime in the summer of 2025.

Hall’s Dexter Morgan returning on the small screen for longer than just a limited series, while also addressing and attempting to repair many of the unresolved stories, complaints, and divisive changes fromDexter: New Blood.
