Afterwards, Dexter plants all of his Arthur artifacts (including a pic of Christine) in the cab of Beaudry's truck, ensuring that the cops will connect the dots from him to Trinity. And since we're all very stupid, Dexter narrates his entire process. So now it's not just his voice-over or the imaginary subconscious father figure leading us by the hand, it's Dexter himself. Brilliant.
Christine gets home and immediately calls her dad. She tries to explain why she hasn't returned his calls, but be blurts that he knows where she's been, and she's not to call him anymore. Click. Harsh.
That night, Dexter plants still more items of Arthur's, this time at Beaudry's ramshackle abode. And finally, he places Arthur's bludgeoning hammer in Beaudry's toolbox. Done and done.
Dexter gets home, and as he's walking up to his front door, he spots Elliott sitting on the stoop next door. Rita is peering out through the blinds and takes particular interest in Dexter crossing the lawn. But she doesn't try to stop him. Dexter greets Elliott, who's shitting a smallish brick as he stands up. "Stay the hell away from my wife," says a surprisingly territorial Dexter. Deflated, Elliott begins with, "Jesus, Dex..." but before he can explain, Dexter hauls off and punches him. He moves in to do it again, but Elliott begs off. He gives a few mealy-mouthed excuses, and finally Dexter just says not to touch her again. The he goes home, the triumphant caveman, and Rita is surprisingly not pissed off. "I'm glad that you cared that much," she smiles. Okay, I know we're like two scenes removed from Dexter tearing into a man's throat with a power drill, but THIS is making me queasy. Rita kisses Dexter's sore punching-knuckles and helps ice them down. They both giggle about Dexter the Unlikely Fistfighter. Whatever. She deserves him.
The next day, at work, LaGuerta and Angel meet in Matthews's office and smugly inform him of their nuptials. And I do mean "smugly." They basically tell him that if he pursues (perfectly legal) action against them (for falsifying an affidavit), he's gonna look like a big, mean, anti-marriage jerk. It's really making me not like them. Matthews, who knows he's been beat: "I can only marvel at the level of cynicism. Using the institute of marriage as a cheap political ploy. You must be very proud of yourselves." And yeah, in a vacuum I guess that counts as an oblique nod to current events, but it's weird lining Angel and LaGuerta on the bad side of that line. Whatever, nobody cares about this storyline anyway.
