'Dexter' recap: Sex, Lies, and Videotape

After last week's gasp-inducing final minutes -- when Jordan Chase all but declared war on Lumen and Dexter -- we knew something big was going to go down this week. Little did we know that episode 10's biggest moment would be less about Dexter and Lumen's destruction and more about the pair's union -- in the bedroom.

But there's so much to cover before we get to that, like Lumen's first kill, Deb's spot-on theory about a vigilante killer, and Liddy's highly incriminating new evidence that's going to bite someone in the ass sooner than later.

First, we picked up with Dexter shipping Harrison off to Orlando to his grandparents' house as a precaution following Jordan's threatening conversation with Lumen. Hopefully the cute little tyke isn't there too long; if Astor was any indication, the grandparents don't have a shining track record in the child care department.

As if parting from his son for the first time since Rita's death wasn't enough to poop on Dexter's day, he arrived at work to find out that the team was once again investigating Cole in the barrel girls case.

Dexter seemed surprised to learn this, but I'm fairly certain they pointed this out in the last episode. Correct? Then again, maybe he was too distracted by the situation with then-missing Astor to note it.

Dexter knew they'd never track Cole because he had already thrown the smug jerk's body into the sea in pieces. But Deb and Quinn were none the wiser, so they were shocked when they went to Jordan's Apple-sponsored office and found out Cole had been missing for two weeks. Deb was quick to jump on Jordan (not literally) for failing to report Cole's sudden departure to the police, and her curtness earned her a spot on Jordan's bad side. She knew Jordan was involved somehow, but in the absence of real evidence, they moved on to Cole's house in search of a lead and found much more than they'd hoped.

First there was the blood -- Cole's blood. It had been left there from the night Dexter and Lumen had broken into his house, and Lumen had hit Cole to save Dexter. "You don't miss a thing," Dexter told his sister, before adding in his head, "…unfortunately." Deb's increasingly sharp instincts only created more problems for Dexter and Lumen as the investigation went on, with the most notable threat to their cause beingDeb's  theory that there were two good guys on the hunt for the raping bastards: the police and a vigilante killer. Her hypothesis was later supported by a fact first pointed out by Masuka: There had been 12 locks of hair at Boyd's house but 13 known victims, meaning one had gotten away. She also pieced together that rapist DDS from a few episodes back was also connected to the crime. So with two suspects vanished and one dead, it was a more than suspect situation, argued Deb.

I've always admired how Deb uses her brain on the job. She thinks about the cases -- unlike the other detectives who seem to sit around in their oversized, ill-fitting shirts waiting for evidence and leads to come their way. She is and will always remain the only person capable of piecing together Dexter's second life. And it seems more and more like that's the path this storyline is headed. Anyone else have chills?

Along with the blood, the team also unearthed Cole's DVD collection, and we're not talking romantic comedies and Jerry Bruckheimer flicks. Cole had kept recordings of all 13 brutal tortures -- Lumen's included. (Even though we only heard the sounds, but they still made my stomach churn.)
