Masuka finds that LaGuerta has sent a blood slide to an independent laboratory for analysis and asks Debra whether he is going to be fired. Debra calms him down and goes to LaGuerta's office that discloses that she believes that the Bay Harbor butcher is still alive. Debra offers to help her to cover Dexter, but when she tells to her brother, he unsuccessfully asks Debra to step back. While cleaning his boat for Harrison's return, Dexter finds vestiges of blood and soon he learns that it belongs to Louis. Then he discovers that the dangerous Isaak killed Louis and now is seeking revenge against him and the detectives of the Miami Metro for Viktor's death. Dexter warns Debra and protects her and he plots a plan to get rid of Isaak that does not work as planned. Dexter also discovers the truth about the involvement of Hannah McKay in the crime spree. Quinn surprisingly accepts bribery from the Koshka Brotherhood. Debra disappoints Angel to protect her brother and vanishes with a photo that would compromise Dexter in LaGuerta's investigation.

Hannah McKay is not innocent as she pretends to be, and now Dexter knows. Quinn disappoints the fans of this series, apparently accepting the bride in his car. My vote is eight.
