In “Dexter” Season 5 Episode 5 “First Blood,” Dexter’s anxiety over whether his infant son Harrison will follow in his father’s footsteps is exceeded only by his fear that Lumen, the traumatized woman, will do something stupid.
That something is to start trying to kill the men who tortured and raped her. Spoilers follow.
It is certainly understandable why Lumen would want to execute a little street justice. She cannot bear to be touched by any other human being, even a female security officer who pats her down at the airport. And, as we say in Texas, these are men who really, seriously need killing.
The problem is that Lumen, unlike Dexter, is not very good at it. Going after what turns out to be the wrong guy in a public place with a gun would not seem to inspire confidence. Besides, urged on by his inner step dad, Dexter really does not want Lumen to become a killer. He may not get what he wants.
Is Dexter doing this out of some stunted form of compassion which he, as a sociopath, should not actually feel? Or is the motive more practical? If Lumen is caught by the police trying to waste her tormentors, his name is bound to come up. That would be inconvenient.
In the meantime, Debra is hot on the trail of the Santa Muerta killers. More corpses, being eaten alive by various vermin, turn up. A little leg work by Debra turns up something that looks like a tattoo. The tattoo looks like an eye, but its significance is not immediately apparent.
It is not readily apparent until the tattoo turns out to be a night club stamp. Now knowing where the San Muerta killers hang out, Debra senses the end of the hunt is nigh.
All is not well with the Laguerta/Angel marriage. Angel, being the suspicious and jealous type in any case, somehow gets the impression that his wife the Lieutenant is carrying on with the Internal Affairs investigator who is making his life uneasy. Things do look suspicious, with unexplained late nights, car rides, and finally a cheap motel.
But all is not as it seems. Angel should really be a more trusting husband.
Finally, Quinn, now under suspension, is still very much on the trail of Dexter, whom he thinks (correctly, as it turns out) was somehow involved with the Trinity Killer, the late and unlamented Arthur Mitchell. Quinn enlists the help of an old friend in this hunt. Now Dexter really has yet another reason to be worried.
