"Scar Tissue" is the fourth episode of the eighth season of the American crime drama television series Dexter.
Set in Miami, the series centers on Dexter Morgan, a forensic technician specializing in bloodstain pattern analysis for the fictional Miami Metro Police Department, who leads a secret parallel life as a vigilante serial killer, hunting down murderers who have not been adequately punished by the justice system due to corruption or legal technicalities.
According to Nielsen Media Research, the episode was seen by an estimated 2.47 million household viewers and gained a 1.2 ratings share among adults aged 18–49.
Vogel (Charlotte Rampling) starts treating Debra (Jennifer Carpenter) for her PTSD by taking her to the shipping container where she killed LaGuerta.
Quinn (Desmond Harrington) has passed the sergeant's exam, but Matthews (Geoff Pierson) tells Angel (David Zayas) that he prefers Detective Angie Miller for the position.
However, he is surprised when the girl, Niki (Dora Madison Burge), introduces herself as his daughter, given that he was a sperm donor during college.
While Debra feels guilt for killing an innocent man, Vogel insists "in your heart, you know you will always choose Dexter."
During this, Debra discovers a recorded session where Harry (James Remar) expresses disgust after witnessing Dexter killing a man, feeling he cannot live with it.
