Looks like Rizzo is really dead, dead. Either that or he's particularly good at lying on the ground immobile with a bloody stomach wound. So Jack's got a big choice here: He can either go to Mia and tell her that he's the one that killed her dear old disgusting dad, or he can lie to her about it. Naturally, he lies, because being honest with your girlfriend isn't something that this show would ever recommend doing. And then he ends up also lying to his brother and creating a whole bigger tangled mess in the process. And Savino isn't really helping matters, in that everyone immediately thinks that he's the third man involved in killing Rizzo since he stood to gain the most. And because, well, he really was indirectly responsible. Still, Savino tells Jack that he'd be wise to keep his mouth shut or Mia will figure it out and stop having sex with him. Besides, it looks like the dead hooker who was at the house with Rizzo and Jack had a shady boyfriend who they can maybe pin this whole thing on. Since there are nothing but white pickup trucks in Vegas and that's the only real clue they have.
While all this investigating is going on, Mia spends most of her time moping and feeling remorseful about the fact that said nothing but shitty things to her father the last time she saw him, and then she takes Savino's offer to return to her job, but also negotiates herself a fancy promotion as head of casino operations.
And when Savino isn't being hauled in for questioning/threatening by Katherine, or telling Jack to shut up, or giving Mia her job back, he's dealing with the Chicago problem. Which is that they want double the skim they have been taking, but if Savino and company comply and make Chicago some extra cash, they won't send another jerk like Rizzo out to oversee things. Also, Savino has the annoyance of Tommy (played by Dollhouse alum Enver Gjokaj), who is a talent manager at the Hacienda who keeps stealing his musicians. Turns out it was just a ploy to get Savino's attention and a job, but it almost gets him killed in the process. But now he's working for Savino, who either seems to respect him or might be keeping him close to murder him later. Hard to say so far.
In Dixon news, his flirting with women is interrupted by his old high school chum who has turned to stealing cars and racing in order to make cash to support his kid. Dixon wants to bust the big crime ring, but his buddy Pete nearly gets killed in the process. And that's when Ralph has to step in to help little brother, because Dixon can't be trusted to be entirely competent on his own. This involves Ralph flirting with a cute redhead to get information, and a potential date, and taking down the crime ring. As a bonus, he also figures out that Pete's ex-wife and her new boyfriend were the ones who tampered with his car so they could take Pete's kid away from him. But while Ralph can figure out Dixon's case, he doesn't even have a remote clue that his other brother is a murderer, involved in tampering with FBI evidence and breaking innocent watercoolers in the process.
At the Savoy, some crooner is warbling about trouble coming or something. At the bar, some slick guy in a suit butters up Savino for getting in on the ground floor with "Dickie Fontaine," but that's just one of the smart moves he's made since taking over the joint. Savino is wary, but pleased and when the charmer introduces himself as Tommy Stone -- who works over at the Hacienda -- Savino cracks, "We all have to make a living." Stone says his friends in Hollywood tell him Fontaine's booking fees will quadruple once his record comes out, but of course Savino already knows that, right? Savino, obviously lying, pretends he does and as soon as Stone leaves, Savino -- falling for what is clearly a con -- calls Cota over to say he wants to lock Fontaine in for a year and his current price.
Elsewhere, a shaken Jack washes his hands in the bathroom of the hovel where he shot Rizzo and it turns out I was wrong when I assumed Rizzo wouldn't actually be dead -- he's getting cold on the floor, still lying where he fell. Jack -- obviously anxious and not at all thinking straight -- takes Rizzo's gun and gets the hell out of there. The only real explanation -- since this was an entirely justified kill -- is that he doesn't want Mia to know he did it. I guess he'd prefer to lie about it first and THEN have her find out?
Anyway, Dixon is hitting on some comely European tourists and ignoring the radio report of a stolen black Thunderbirds running from cops along Fremont (the only street in Vegas) when the car goes running past. He manages to calm his boner long enough to leave the women and gives chase in his own car, cutting the guy off and pulling his gun on him, only to find out he knows the guy, who is named Pete. (Just one name, like Cher.)
Back at the station, Dixon wants to know what happened to the straight-A star ballplayer he knew from high school, but apparently has disappeared. Turns out he didn't so much disappear as knocked up his girlfriend and so got a job and settle down. Dixon must be a really good friend if he didn't know that. Pete says he's stealing cars now because he needs the money; things aren't going well with his wife and he tells Dixon he can't do time because of everything he's got going on, which is, apparently, a job and a family? Dixon presumes Pete's not doing this on his own, since there have been a rash of auto thefts lately and Pete admits he boosted the Thunderbird for a guy who is part of a ring of mechanics who strip the cars for parts for sale in L.A. He'll be at a drag race tomorrow night and Dixon's very interested in that.
