CSI - 'In Vino Veritas'

Countless CSI episodes have started the way this one does - rich fancy people at a fancy party. This one's weird though, because it's a guy and his wife(? Girlfriend?) going into a mansion and she seems like she doesn't want to be there, then he says "Well I'll look like an ass if I back out now, besides, I really want this" and then he has to tell a password to some burly dudes and they let him in - to a room full of people, like 80% women. Weird. Then the guy goes and talks to an older man who looks like he's in charge, and his henchman. They start talking about 'virtue' and he asks how much it costs - then they lead him to a dark room with a red altar in it - someone lifts the cover and the audience can't see it, but the first guy says "Whatever the price, I'll pay it". It's all very cloak-and-dagger or secret-society-esque.
Next thing you know, Greg and Sara are opening a barrell in an allyway and pulling out a guy in a tuxedo - only his face is so decomposed that I can't tell if it's the newcomer or the henchman.
The 2 Davids are pulling the guy out, and Hodges smells the barrell and says it smells like wine. Then as he's rolling it down the hall, he sees a guy looking in Russell's office and OH MY GOD IT'S GARY SINISE!!!! I SMELL CROSSOVER EPISODE!!!!

He's there to visit Christine, his girlfriend.
The body has holes like there were nails driven through his hands. And he has cufflinks with JD engraved on them.
Hodges knows all these fancy wine-related terms because of his fiancee, and Morgan would rather stick to vodka.
Sara finds that the dead guy had eaten whale sushi (EW!) before he died, and then they go to talk to a chef who was arrested for selling that stuff - he's unloading big containers of wine (under guard? wha-?) and when he says 'who's asking' what they are, Brass gives the obvious answer: 

"Me. And I'm not going to ask again."

Apparently the wine is worth $100,000 a bottle, and then Mr. Vogel, the old guy from earlier and the mansion's owner, turns up. His house is beautiful. Apparently he's an auctioneer and sells really old wine.
He recognises the cufflinks (not the bloated guy's face) and says they belong to a Jack Davari, who was a huge collector. He was in a fight with a Mr. Ratelle, who owns a winery and was trying to buy back a case of his family's own 1936 wine. He was not successful.
Meanwhile Russell and Mac are going to visit Christine at her hotel room, and she won't answer he phone - then they see blood on the door handle and bust it open, there's no one there and it's a huge mess in the room with blood everywhere. Nick finds a bloody man's dress shirt under the bed, that the victim was not wearing, since all the blood was on the outside of the shirt. Also there was a broken glass table.
Then Brass finds out that Ratelle has broken into Vogel's wine cellar and is smashing bottles everywhere, and even though I don't like wine, it's ridiculous because so much money is just getting smashed on the floor. And he has a ridiculous French accent to match hahaha.
The blood on the shirt and in the room was a woman's probably Christine's, and then Morgan finds a bottle of the '36 in Ratelle's car, and Hodges says that there is something wrong with the smashed bottles. He thinks they're fake. SO he decides to open the $82,000 bottle - "for science".

Science, my ass... He wanted to taste fancy wine!!!

And he and Morgan sit in the lab drinking it ahhaah.. The fake wine had traces of readioactive isotopes in it, from the soil where the grapes were grown. Meaning it was post-WW2 wine, not 1936.
Ratelle admits to knowing that Davari was selling fake Ratelle wine, because there are only 609 bottles left in the world, and he knew where they all were, so it could not have been real wine that Devari was selling (Brass says "Actually, I think it's 608, I saw the lab report." HA!).
Nick is assembling the giant puzzle that is the glass table, finds a fingerprint of someone unknown, and a diamond. He traces the serial number on the diamond to a jewlery store, and when they go there, hte sign on the door says 'closed' but the door is open - and so is the safe. And there's a dead guy. And Christine's cell phone.
The dead guy is the owner of the store, and he was apparently trying to invest in Christine's new restaurant that she was planning to open in Las Vegas (plans Mac didn't know about) and there was blood from (probably) her and a second man at the scene - Jimmy Boyd, who has a criminal record and worked at Christine's New York restaurant.
The man who we saw at the beginning was Jonah Drake, the man who ended up buying the '36 Ratelle. And Samantha, his (now) fiancee, they say that the wine was real and that he wanted to buy more but she wouldn't let him.
Sara and Greg go to a warehouse Jack owned, which is full of a counterfeit wine operation. And the corking machine is what punched a hole in Davari's hand. The fingerprints match the guy named Tom Scola who was moving the wine. He was Davari's partner in the operation, but has an alibi for when he was killed.
Mac doesn't believe that Christine would be mixed up with the criminal types, and then they found the jewlery owner's car, and there is blood in it, and a blond woman in the trunk. They look all sad and disappointed - then Russell rolls her body over, and it's not Christine.
There was blood from Tom Scola in the warehouse, but he was definitely at the club he claims to be at. But there was heightened levels of estrogen in his blood, because he was a bone marrow donor. Which means that the DNA wasn't from him, it was his recipient sister. Who is Samantha, the fiancee from before. She was involved in the con, but fell in love with Jonah and she wanted Jack to leave him alone, and then he insulted her and she slapped him, he attacked her, and she turned on the corking machine and shot him. And now I feel really bad for Jonah. 

As Greg put it, "He only loved 2 things in life - you, and that wine. And they're both fake."

There was gold paint on the jewlery store owner's car, that matched Boyd's car, and they find him, alone. Kim the dead woman in the car was Boyd's girlfriend. Christine never came to Vegas because Jimmy owed a loan shark and was going to scam the jewlery store owner, using his girlfriend as a stand-in for Christine. But his brother had her with him, and then the loan shark abducted both of them, and is threatening to kill them both if he doesn't get the diamonds. And Mac wants to take him back to NYC to rescue his girlfriend, and Russell says 'You can't do that! Not alone at least - I'm coming with you.'
CROSSOVER TIME!!!!
