"Love Hurts" & "Love Kills": Nathan Grant born Nicholas Kosta is a notorious Philadelphia criminal who fled to LA after murdering his wife. He became secretary of a support group for love and sex addicts, using the meetings to find cases that reminded him of his wife. Upon finding a victim, Grant would stalk the women for information and sexual gratification. Upon learning enough he would break into their homes, steal a knife and stab them to death becoming a meticulous Serial Killer and allowing him to relive killing his wife again and again. Grant then left their exes to take the fall for his crimes. Successfully murdering four women in this manner over six years, his cooling off period rapidly deteriorated between each kill. Following killing his fifth victim, Grant immediately began stalking Pam Tyler; two days later he attempted to kill her but was fought off. Undeterred, a few days later he killed his sixth victim, engineering events so the terrified woman ran straight to him. Realizing the police were after him, Grant framed another group member, and attempted to silence Special Agent Vicki Gregg.
Critical Dissonance: The show isn't well-liked by critics, with one reviewer using words like "misogynistic" and "vile." However, it's popular with viewers and has pulled in consistent ratings.
Chris Powell for using his influence to avoid being convicted of rape. He then stalks women to scare them to death with their phobias and film them for his amusement.
Perry Whitley takes the cake for stalking Beth after their close encounter in "Pilot." He covertly harasses by sending her things from her past and is the Boy Toy to her friend just to get closer to her. Though it really flip-flops on him. As he seems to be unable to control himself and changes from being a calm stalker to a guy desperately seeking for help from his obsession issues.
Unintentionally Unsympathetic: Beth Davis. One would feel more sympathy for her if she didn't alienate everyone close to her and act like a Jerkass to her team when they express genuine concern for her. Gets even worse when essentially the whole team has come up to her at different points asking if she is alright and she still pretty much just tells them to go away.
