with her. At first, Lumen is petrified of Dexter, believing that he will kill her for being a witness to his crime. Despite Dexter's constant assurances that he will not kill her, Lumen refuses to trust him. After an escape attempt, she is once again captured by Dexter. Instead of imprisoning her again, Dexter shows Lumen the bodies of Boyd Fowler's previous victims, and assures her that, had he not killed Boyd, she would have been next. It is at this point that Lumen confides in Dexter and tells him that Boyd was not the only one who hurt her. It is ultimately revealed that she had been held captive for an unknown amount of time, during which she was repeatedly raped and tortured by a group of five men. 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 get on with her life and leave Miami. Upon breaking into to her motel room, Dexter discovers that she has been attempting to track down the group of men who raped and tortured her. He learns that she has gone to kill a sex offender whom Dexter, having hunted him down earlier, knows to have been wearing a tracking anklet. He stops her in time and this 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 Dan Mendell, 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, Mendell calls his co-conspirators on Lumen's cell phone, confirming her suspicion and prompting Dexter to kill him by snapping his neck. 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.
