Deb and Angel are getting lunch, Deb saying, "Look, this wasn't my idea!" "Could've said no," says Angel coolly. "Come on, Angel, we have a job to do," says Deb. "Since when is it my job to prove to a fellow police officer that I'm not a serial killer?" Angel demands. Deb says that's not what this is about: "This is about trying to figure out who had the motive and opportunity to kill all eighteen of our victims." Angel isn't convinced that anyone in the department is capable of pulling off the crimes, and Deb says, "Then help me prove it! Go through the Rodrigo case with me. Look, it is not just you. LaGuerta's cooperating on her old cases! Even Matthews is coming in." Angel looks at her, and after a pause, he wordlessly procures a file from his bag: "The Rodrigo file." "You just happened to have it with you?" laughs Deb. Angel: "I'm a reasonable man." They smile at each other, and then tuck into their sandwiches.

Back with Dex and Lundy, Dex is going through the specifics of the file: "You know how it is. The defense attorneys bring in their so-called 'blood experts' to counter everything I say." "I'm familiar with the process," clips Lundy. Dexter is shaken, and starts to flail a bit: "I understand how this may look like sloppy blood-work to the layman -- that's what Rodrigo's defense convinced the jury of -- but as you can see, the low-velocity blood drops clearly point in the direction opposite to that in which we know Rodrigo to have fled, which makes it impossible --" "Except those low-velocity drops were revealed to actually be ninety-degree passive drops that were given tails to the angle of the floor," says Lundy. Oh, shit. This guy knows his blood-work, so this is going to be a tough sell. Come on, Dex, you can do this. He tries again: "Perhaps...but, if you then examine the blood trail --" "Which we know isn't a blood trail, but projected blood," says Lundy. "You're not winning me over here, Morgan." Dexter sighs, and after a rest, says, "Truth?" "By all means," says Lundy. "I was overworked," says Dexter. "I was carrying half a dozen cases at once. It was a heat wave, which means a spike in...homicides. This one got pushed aside. I didn't write up my summary until an hour before the trial, and I obviously overlooked a few things." "A murderer walked free because you were overworked?" asks Lundy. "Yes." Dex looks ashamed, and Lundy stares at him harshly. Yikes, dude. Is it warm in here?
