In “Dexter” Season 5 Episode 4 “Beauty and the Beast,” Dexter finds himself in a conflict between the Code of Harry rule that states do not kill an innocent and the rule that states one should not get caught.
It seems that one of Boyd’s victims saw Dexter dispatch Boyd. She has been tortured and is out of her mind with pain and fear, despite everything Dexter does to try to nurse and comfort her.
On top of that, Dexter has to take off and help Debra at a crime scene in the latest Santa Muerta beheading. Dexter is able to ascertain in a minute that one of the killers smoked a cheap cigar, the butt of which they get a partial thumb print from.
With all this bother, Dexter forgets that he has left Sonia, the nanny from the auld sod, alone with Harrison for far too long. Sonia resigns in annoyance.
A little investigation uncovers that Dexter’s big problem is named Lumen, who hails from out of town and has an unpaid bill at a local motel. She also seems to have run away from her family, who really wants her back.
In the meantime, Quinn is on the hunt for Trinity’s family because he would really like to show them a picture of Dexter, who he believes (correctly as a matter of fact) that Dexter is Kyle. This gets both the FBI and Laguerta angry with him.
Laguerta is also angry with Angel, whom she orders to apologize to the fellow whom he beat up in the bar. This does not, however, deter internal affairs.
Using the thumb print, the two beheaders are identified and located. Angel leads in the assault team. Unfortunately, they get away; one takes a hostage to keep Debra off of him. Debra manages to save the hostage’s life.
In the meantime, Dexter has to sweet talk Sonia into giving him another change and Lumen into not trying to run and to trust him. The former task proves easy; Sonia really likes babies. Lumen is a somewhat harder case. Dexter finally convinces Lumen by taking her to Boyd’s dump site and telling her about Rita. Lumen understands an outraged husband wanting to kill people like Boyd, and it seems she will not rat Dexter out.
However, here is the complication. Boyd was not the only monster who abused Lumen. There was a whole gang of vicious creeps who did things to her that cannot ever be described. And now, Lumen has concluded that they have to pay. Will Dexter help?
A poor serial killer’s work is never done,
