The Dexter prequel series Dexter: Original Sin has a prime opportunity to fix one of the most overlooked plot holes that the original show never addressed. There weren't many plot holes at all in the original show, but one subtle issue persisted through all eight seasons of Dexter. For a show as well written as Dexter was, it's almost unheard of for a plot hole to be completely overlooked like that. It also concerns a central part of Dexter's killing ritual, so as minor as it may seem, it has massive implications on his ability to evade the police.

Even though Dexter ignored this plot hole for years, Original Sin is going to have to address it soon. Because of Original Sin's timeline, the prequel show has done everything from solving Dexter: New Blood's M99 vs. ketamine debate to explaining why he started showing his victims photos of their victims.
