List of Dexter characters
Her mentally scarring experience has left her with a desire for vengeance, and she attempts to enlist Dexter's help to hunt down and kill the remaining perpetrators. He is willing to do this for her, but suggests that she gets on with her life and leave Miami. Upon returning to her motel room, Dexter discovers that she has been attempting to track down the group of people who raped and tortured her, and has gone to kill a sex offender who Dexter, having hunted him down earlier, knows to have been wearing a tracking anklet. This revelation leads Lumen to realize she does not possess the skills or experience to discover the identities of the men who tortured and raped her and kill them. However, finding herself unable to leave Miami, she shoots a man she suspects of being one of her abusers, due to recognizing his distinctive smell. When the man escapes after being shot once in the leg, Lumen calls Dexter, who helps track down the wounded criminal, albeit reluctantly, and cautions her about killing the wrong person. Protesting innocence at first, the victim calls his co-conspirators on Lumen's cell phone, confirming her suspicion and prompting Dexter to kill him. They later meet at Dexter's house, where Lumen reveals that his death brought her a sense of peace, stating that the only way she will be able to find that peace again is to kill all of her other abusers. Dexter recognizes this as being her own "dark passenger", and agrees to help her.
