WARNING: SPOILERS ahead for Dexter: Original Sin episode 8.After eight episodes, theDexterprequel seriesDexter: Original Sincontinues to ignore a crucial detail between Dexter and Brian from the original series. After Brian’s infamous ice truck passed Dexter inDexter: Original Sinepisode 7, it became clear that Dexter’s biological brother had been keeping a watchful eye on him throughout the season. Although Brian appears in severalOriginal Sinflashback scenes with Harry and Laura Moser, he doesn’t have a big role and hardly talks to Dexter or his mom all that much.
Dexter: Original Sinepisode 8 finds Harry searching for a serial killer with Maria LaGuerta. The killer murders a psychologist from Tampa, which leads Harry and LaGuerta to search through the doctor’s patient records, only for Harry to come across Brian’s file. Without even needing to prove it, Harry knows that Brian is likely the killer Miami Metro is searching for. These developments set up a potentialconfrontation between Harry and Brian, who haven’t seen each other since that fateful day in the shipping container years before.

While Brian is seen in many of theDexter: Original Sinflashback scenes, he and Dexter are hardly ever depicted interacting with each other, which implies a distance in their relationship.

Theflashback scenes inDexter: Original Sinare focused primarily on Harry and Laura’s relationship after she becomes a police informant for Miami Metro. These scenes offer a compelling look at their dynamic with never-before-seen detail, and add entertainment value and backstory to the series. That being said,young Dexter and Brian are treated mostly as background characters in these scenes, which is unfortunate since it would have been interesting to see their sibling dynamic at that age. Both boys are quite young during these scenes, but old enough to offer some insight, such as Dexter calling Brain “Biney”.
