What happened in the previous episode of Dexter: Original Sin?

Dexter: Original Sin season 1 episode 9, Blood Drive, explored Dexter and Brian’s traumatic past. The episode started with Brian Moser charming an older woman at a bingo hall. She turned out to be Barb, the child welfare worker who had separated him from Dexter years ago.

Meanwhile, Harry Morgan realized that his choice to raise only Dexter had pushed Brian toward darkness. The episode featured flashback sequences that showed how Harry found young Dexter and Brian in a shipping container covered in blood after their mother, Laura, was murdered.

Harry decided to take in Dexter but not Brian, which shaped both their lives. Brian felt abandoned and hurt and tried to suffocate baby Deb, which was one of the reasons why he was left out of the Morgan family.

In the present, Dexter is focused on tracking down Captain Spencer as he suspects he could be the child kidnapper and killer. While he was able to catch Spencer, he did not kill him and only cut his finger off.

Dexter hoped that Spencer would lead him to his kidnapped son, Nicky. The episode ended with Brian fully embracing his dark side as he brutally murdered Barb. This set the stage for an intense season finale where the Morgan family dynamics would shake up with Brian’s entry.
