Savino goes to see Diane in her dressing room, and she purrs that she knew he'd come eventually. He turns up the radio and starts dancing with her, feeling her up and kissing her -- clearly checking for a wire -- and even rips open her blouse. She's enjoying it, but once he's determined she's clean, he tells her he knows about the FBI, and just because she's not wearing a wire it doesn't mean she's not a rat. He wants her gone, and angrily gives her until morning to make herself scarce.
Jack's making a report on Pete Holm to Yvonne, despite Ralph's grousing that it's a waste of time, at least until Jack mentions an injury on Holm's right hand -- he winced when Jack shook it. This twigs with Ralph because Ginny had an injury on her left. They quickly deduce that the two of them stuffed Merrick into the cement mixer, using Yvonne as a prop as they walk through it. "This is exactly why I left my last job," she says, whatever that's supposed to mean.
Holm and Ginny, in Ralph's office together, deny the allegation, except Ginny blurts out a detail of the body's condition -- the fact that it was beaten before getting thrown into the mixer -- that only the cops and killer knew. "Nice work," grumbles Holm, as Ralph makes them put their hands on the desk, where he finds mirror-image wounds from a cement mixer blade on their wrists. Book 'em, boys!
Afterward, Jack's working on the paperwork when Ralph gruffly says he'll take care of it, because Jack's got somewhere to be. Jack's not going to pass that up, so he heads for the door, wishing his brother a sincere Merry Christmas before he goes, and the brothers smile at each other.
Over at the Savoy, Dixon appears to be hosting and bartending a Christmas party for a bunch of deputies and assorted hangers-on. He snatches some mistletoe to hang between him and Yvonne, but she slaps him and walks off, leaving him to chase her and demand to know why she's so bossy. "Because you love it," she says, and then she roughly shoves a bucket in his hands and tells him to go get some ice. Despite his apparently raging boner, Dixon eagerly does so, while Yvonne bites her lip all turned on.
In the hall, he runs into his uncle. "What are you doing here?" says Jack, surprised. "Nothin'. You?" asks Dixon. "Nothin'," says Jack, and they go on their separate ways. Mia lets Jack into her room, oblivious to the bombshell she's about to drop on him that they can't see each other anymore. Jack jokes he knew he should have got her Patsy Cline, but Mia's serious, what with the conflict between their families (in all senses). "I'm not afraid of your father," Jack says. "You should be," Mia says. Yeah, I'm kinda with Mia on this one. Jack asks her if it wasn't working for her the other night when she was in his arms on the dance floor, because it was working for him. "Jack, don't make this harder," she says, and opens the door. He asks if this is what she wants, and she says it doesn't matter.
