LaGuerta and Captain Jack are keeping up their little version of Who's Afraid Of Virginia Woolf?" when LaGuerta finds, in a Doakes evidence box in her garage, a tackle box that contains deep-sea fishing lures -- and a key. We'll find out there's an address on a label on the tackle box...
...so we cut to them arriving at the very dilapidated seaside warehouse Dexter had up on his computer earlier. Captain Jack speculates that Doakes probably got rid of his boat when he figured the law was on him, which sounds easier said than done if you ask me. LaGuerta agrees with me, at least to the extent that she points out Captain Jack is jumping to conclusions, but soon Captain Jack is telling her to call the forensics team in, as, in a cubby, he's just located a bunch of BHB-looking paraphernalia, including some black trash bags. I'm shocked that no one paid for the product placement on that one. No wimpy trash bag is going to hold the dismembered pieces of a corpse!
Later, someone from the team is holding up a set of knives -- apparently also recovered from the place -- and says that while the blood on them is too degraded to analyze, the print on it belongs to Doakes. Captain Jack is like, "That's a wrap!" but LaGuerta pulls him aside and points out that Dexter is a forensics expert, and as such could have set this up. Captain Jack rebukes her with his customary (and hilarious) lack of tact, but when LaGuerta emotionally asks what's wrong with him, he softens a bit in asking why she can't let this go. She confesses that she feels she owes it to Doakes to clear his name, but their biases are leading them to opposing conclusions here and he tells her that while she's great at the political game, she's not so much an investigator and she should drop it and, by the way, live up to her end of the bargain they made. It is kind of awesome how they've made LaGuerta this Cassandra, how her motivation to clear Doakes makes her tenacity entirely believable yet is also a reason people are quick to dismiss her theory. LaGuerta tells Captain Jack he'll get what's coming to him, which is a choice of words I wouldn't be too thrilled to hear coming from her. After he wishes her Feliz Navidad, he bails.
Deb steps out onto her porch for some reason and runs right into Hannah, who tells her she's not there to fight, but to talk about Dexter. Deb is pretty dismissively hostile - shocker! -- but agrees to hear Hannah out, so she says that Dexter is happy and she figures that's a pretty big deal with all the pain he's been through. Deb admits that she can't argue with that, so Hannah plows on that Dexter's been talking about a future with her and she knows it would be very meaningful to him if she and Deb could find some common ground. Deb notes, somewhat sardonically, that this is for Dexter's sake and when Hannah agrees without acknowledging the tone, Deb takes a swig of water from the bottle she's holding and a long moment to consider before saying that Dexter does seem happy, and Hannah replies that she loves him and wonders if they can work out their issues. Deb says sure, she thinks she can, and then steps forward: "It's because I love Dexter that I'm willing to do whatever it takes to protect him from you. I'm not going to give up until your murdering ass is behind bars for good. That's how we're gonna work out our issues." I mean, it's no Roya Hammad almost literally exploding in Carrie Mathison's face, but it's still a pretty good burn. Deb is like, lates, and Hannah, defeated, takes off.
