So Dexter's in lockup, pacing angrily and arguing with Harry and His Warming Glow. Harry gives Dexter shit for losing it on a cop, while Dexter rages about how he couldn't well get caught with an unconscious body ("fuck you, it's your number-one rule!" he yells, which amused me). Harry says that's not why he flipped out. Dexter's face gets all evil-grinnish as he seethes that he couldn't just let the cops find Arthur -- HE has to do it himself, for his family. Now, while Harry smugly uses that statement to further advance his theory that Dexter's family is ruining him, I need to address that "I have to be the one to kill him," shit from Dexter. I appreciate that the show is attempting to answer these questions about why Dexter wouldn't just let the cops have Trinity, but this sudden zeal to dispose of Trinity to protect his family doesn't really explain his reticence to killing Arthur these last few weeks. I mean, on the one hand, whatever, season's almost over. On the other hand ... whatever, season's almost over. Anyway, Dexter says it's our old friend Darkus Q. Passengerious who's to blame. "It's ruining my life," he intensifies. "It is your life," Harry returns. "I don't want it to be," Dexter whispers. O RLY? Well. If Dr. Roma Maffia were around right now, she might consider this a breakthrough. Before committing Dexter to an institution for arguing with thin air for fifteen minutes now.

Miami Metro. LaGuerta's gathered the team (minus both Morgans) for a de-brief. They're having a hard time making this Beaudry thing make sense. He's got alibis for at least two Trinity cycles, and his M.O. on the prostitute murder is inconsistent with the other killings. LaGuerta bitches about Matthews going to the press with Beaudry as the suspect. Masuka deadpans that he knew Beaudry wasn't Trinity, though he can't quite explain how Trinity's DNA ended up all over Beaudry's shack. Then there's Angel, who followed up Deb's postcard lead to Bloomington, where they indeed had a bathtub killing, a jumper, and a bludgeoning that year. But wait! There's more! The cop Angel talked to said that same month, a 10-year-old child went missing. LaGuerta immediately recalls Miami's own recent missing 10-year-old boy, Scott Smith (from two episodes ago). Angel says he called all the other Trinity cities and found boys missing in each one, five days before the cycles began. So Miami Metro is now as caught up as Dexter was two weeks ago. LaGuerta says to bring Scott Smith in.
