Brother Jesse -- a.k.a. Brawny -- wearing yet another plaid flannel shirt, sits in the interview room again. Stabler and Benson tell him that the DNA test lets his brother off the hook but puts him in the hot seat. "Which really doesn't make any sense to us," says Stabler. "We know your brother's bad, but you've been clean all your life." "Can you explain this?" asks Benson. Wheels turn sloowwwly in Brawny's head: "No." Stabler says that a blood test would clear things up, but Brawny is reluctant. "Maybe -- I should -- call a lawyer," says Brawny. Benson tells him he's free to go, and he lumbers out.

Back in the office, Jeffries and Cassidy tell Munch what they've found in the old L & O Backstory Files: back when Ray Gunther was arrested, he copped a sympathy plea, saying that he and his brother were raped by their dad growing up. "Could explain a few things about Jesse, huh?" says Cassidy. "Except the prosecution put Jesse on the stand," explains Jeffries, "and he said that Ray completely fabricated the story." "So how do we know which one is lying?" wonders Cassidy. Cap'n Cragen and Benson and Stabler come in and join the discussion about the Gunthers' "piss-poor gene pool." "You think Jesse was just born bad?" says Benson. "That's bull," says Stabler. "Destiny isn't predetermined." Everyone opens their mouths and recites whole paragraphs about the nature-vs.-nurture debate from my college psych textbook. Benson stalks off. "Is something wrong?" Stabler asks, following her. What -- could it be that one of our detectives is Taking It Personally? "The only way that Jesse makes sense in all this," says Benson, "is that they're fruit from the same poisoned tree." "You don't really believe that, do you?" says Stabler. Benson just looks at him and walks off.

Law & Order: Original Flavor sends over -- Abby! Kick some butt, Abby! Toss that hair! "I understand your DNA test pulled a little Arkansas two-step," she says to Cap'n Cragen and Stabler. Benson is standing in the back of the room, scribbling something in her notebook -- probably "I hate Abby. She is not all that!" Stabler explains to Abby the snafu with the bloodline test. "Jesse's lawyer is already waving the old A.C.L.U. banner, asking where does it stop -- are we going to test every relative of Ray Gunther's?" "No," says Benson. "Just the one that lives in the victim's building." Abby pretty much ignores her and asks them what else they have beside the DNA. "Only lawyers sandbagging us at every turn." Cap'n Cragen explains that there's the video of Seth at the party, but it's tied up in litigation. "Any way of getting it untied?" asks Abby. Cragen says, "Let me see if I can make an end run of my own," as if acting like a football player would impress Abby or something.
