Ralph finds Ray Humphries watching a reel-to-reel film of Tommy's fight with the Russian and it's not long before Ray reveals that Tommy has been fighting his whole life, because his dad used to beat his mom, who died before she could escape him. That's why Tommy's got a thing for the underdog, and why he wasn't going to tell the trainer that he the Russian actually cracked a vertebra, since the trainer would barely let Ray fight due to his asthma. Ray's showing of Ralph his asthma medication is the type of info you know is going to be relevant at the end. Ray has no idea why Tommy would need a gun, since he could kill a man with his fists. Well, you don't need to be a genius to understand that you can only punch as far as you can reach, but we'll let that go.
Now, you're not going to set up that Rizzo is a degenerate gambler with a mean streak without letting us see some of it ourselves, and sure enough, Rizzo pops his cork when he realizes the blackjack is bottom-dealing in order to bust and let Johnny win. I'd have been thankful for that kind of customer service when I went to Vegas, but Rizzo kicks the shit out of the guy. Well, I have a hard time believing Rizzo wouldn't have done the same thing if he'd lost, so either way.
Meanwhile, Dixon is doing a great job over at the Lost Oasis. He's helping carry in booze and reminiscing about winning an amateur strip-tease contest, so it's nice to find out that the Lost Oasis flies the rainbow flag at least some of the time. What he's not doing is paying attention to the bag, and the person with the other half of the ticket has come and gone. Nice work, shithead!
Savino surveys the damage in the private casino, and gets some guff from Rizzo about how Savino thinks he'll OK the restaurant if Savino throws him some peanuts like you would a monkey. Then he's off to the casino proper to gamble. Savino tells a worried Red that they'll just bribe the gaming commission, which will be worth it if Rizzo gives the nod to the expansion plans.
Over at the sheriff's office, Jack and Ralph are trying to wrap their ranching brains around cracking the LASTUS7 code, when they get the double-bad-news whammy of Rizzo being out on the casino floor and Dixon's fumbling of the bag stakeout. On the plus side, a passing glance from Yvonne cracks the code: It refers to the 7 o'clock bus from Las Vegas to Tucson.
So it's off to the bus station, where the Lamb posse boards the bus. Fortunately, the person who picked up the bag has left it on the seat next to her. "Is that your bag, ma'am?" asks Ralph. I'd like to think the other passengers were pleased that the police were finally cracking down on that bullshit thing people do where they take up a whole bus seat with their bag so someone else can't sit down.
