Thetitle ofDexter: Original Sinseason 1, episode 10 is “Code Blues,“which gives a hint about a tragedy to come as it’s the hospital code often associated with heart attacks. This seems to indicate that Harry Morgan may die inDexter: Original Sin’s season 1 finale, asMichael C. Hall’s narration as Dexterin the premiere indicated that Harry would live approximately another year after his heart attack. While that could be delayed until later in the series,Dexter: Original Sinseason 1 is certainly building toward a major event for the Morgan family.

After the backlash toDexter: New Blood’s endingin 2022, which featured Dexter Morgan being shot and killed by his teenage son, Harrison, that resolution was undone as two newDexterspinoff shows were announced:Showtime’s prequel,Dexter: Original Sin, and a new sequel series,Dexter: Resurrection.
How Dexter Morgan Survived New Blood’s Ending
The opening scene of Dexter: Original explains how Michael C. Hall’s Dexter Morgan survived being shot by Harrison in New Blood’s ending.
In the opening scene ofDexter: Original Sin, it’s revealed that Michael C. Hall’s Dexter actually survivedNew Blood’s ending, being rushed to a hospital and revived by doctors. This is used to set up the newspinoffDexter: Resurrection, which will bring back Hall as Dexter Morgan after miraculously surviving his gunshot wound. Though an exact release date hasn’t been announced, it’s been confirmed thatDexter: Resurrectionwill premiere on Paramount+ with Showtime in summer 2025.
