A lot happened on Sunday night’s episode, but the one thing that stuck with me was a desire to implore the writers of “Dexter” to please give Deb Morgan a break already. I was half laughing, half groaning when she asked Quinn to tell her if it was going to end badly. Memo to Deb: IT’S GOING TO END BADLY! Although it’ll be exciting, no doubt, to see how Quinn’s vendetta against Dexter will play out in regard to his relationship with Deb, I wish the show would figure out a way to give her a love life that doesn’t go horribly awry. Even if it means she becomes a nun, it’s time to give her a break.
Otherwise, Sunday night’s episode is about Dexter trying to keep his life neatly compartmentalized: This part of him is a father, this is a blood-spatter expert, this is a murderer. To celebrate a return to old times, Dexter decides to take down Lance Robinson, who kills men he meets online for casual encounters. “Tonight’s the night,” he says as he goes, while we also see Lumen preparing for her own kill. Dexter’s hopes for a tidy evening are disrupted when Lumen calls him as he’s wrapping Lance in plastic. She begs for Dexter's help: She has tracked down one of the men she thinks raped and tortured her but has botched the murder.
Dexter meets Lumen at her murder scene, where she initially blames him for not doing it for her. She discerns that he works for the police department as they track her bleeding, escaped victim through the marina, bickering along the way like a big brother and wayward little sister. Lumen reveals that she never actually saw her attackers’ faces or heard their names, but she knows, based on a smell, that he’s the guy. I’ve been trying to figure out exactly how Dexter sees Lumen (I was worried that they might kiss at the end of the episode and was relieved when they didn’t), but I love this scene, the way Dexter seems so peeved and incredulous when Lumen curses him out.
While Deb and Angel are doing a stakeout on a club to try to get the Fuentes brothers, they get a call about a potential homicide at the marina, which of course just happens to be the potential homicide that Dex and Lumen are engaged in. Then Lumen and Dexter find their man, and a ridiculous bloody screaming match ensues (again, so much for neat and compartmentalized) in which Dan the Dentist claims he’s never seen Lumen in his life. Dexter takes a call from Sonya to hear Harrison say bye-bye (or “die-die”), and when he returns, Lumen has her stiletto against Dan’s throat. While Dexter yells at Lumen for being nuts, Dan crawls off and is conveniently heard on the cellphone telling his cronies that Lumen’s alive -- so she has had her man all along. “They’re gonna find you,” Dan promises Lumen, and then Dexter finally dispatches him. Lumen seems almost happy, but they need to clean up, because Deb and Masuka are on the trail.
