Dixon and Ralph interview Nathan's heartbroken mom and discover that the limping accomplice was likely Nathan's younger brother Russ -- Nathan "filled his head with nonsense," says Mom, and that their dad -- who frequented the sports book just robbed by the brothers -- died just a month ago, but they lost him down a bottle long before that.
Savino gives Cota a suitcase of cash to bring to Farwood to cover Tumbleweed work, and Cota cracks wise about how this the first time he's taking cash to a bank. Not bad!
Then Laura shows up, freaked out that the stage manager asked her if she wanted any of Diane's dresses. She peppers a taciturn Vincent with questions about Diane, saying she didn't seem like a drug addict. Vincent says "these people" know how to hide it, and gets a little angry when Laura persists. "You're asking questions you don't want to know the answers to," he almost snarls, and then gets a little too offended when Laura comes right out and asks if he killed Diane. He denies it, but -- when she reminds him that he promised no more lies -- that it's possible some gave her a "hot dose": two parts heroin, one part strychnine. "Maybe it was Rizzo, or maybe it was just bad luck," he says. And that's about all she's getting out of him.
Jack is over at the Savoy, having learned nothing about Hal Whitford, and wondering why Mia even cares. It's because the big fish gambling up there also gamble downstairs, but they won't gamble at all at the Savoy if they feel they're being taken advantage of. So Jack wants to go undercover -- what is it with these Lamb idiots deciding to go undercover? -- and join the card game. Mia's reluctant but softening.
Based on a tip from Mrs. Auster, the Lamb brothers are interviewing a bar owner but he has already been robbed by Nathan and Russ. The bar owner sports a shiner, given to him by Russ, all riled up by Nathan on account of how the bar poisoned their dad, since that's where he used to drink his paycheck away, near the cement factory where he used to work.
Over at the poker game, the current hand has come down to Hal Whitford and Jack, who might as well wear a shirt that reads "DON'T WORRY I'M NOT LAW ENFORCEMENT" for all the casual questioning he's doing. He takes the pot, though, grinning, when his trip tens beat Whitford's aces and eights. Taking it all in is Mia, who looks less than aroused at her boyfriend's poker and investigative prowess.
