The placard that Castle holds up at the auction at the end had his bidding number as 187. Section 187 of the California Penal Code defines the crime of murder.
The made up Scotch used in the show, St. Miriam, they made a spelling mistake, since Whisky in Scotland is spelled without the e, rather than "Scotch Whiskey" like it said in the bottle. In Ireland it is spelled whiskey.
Beckett: Lanie just swabbed the shard of glass and found trace amounts of alcohol.
Castle: A container of alcoholic beverage, a resentful bartender...
Beckett: And given the location of the Old Haunt, a potential crime scene just two blocks away from the river.
Castle: Convenient for all your body dumping needs.
Beckett: So, Castle... Can I buy you a drink?
Castle: Why, detective Beckett, I thought you'd never ask.
Castle: (about the river) This is the most celebrated body depository this side of the Jersey wetlands.
Beckett: This must be a part of the old sewer system. Castle: Probably used these as access tunnels during prohibition. It's incredible, isn't it? Beckett: Yeah, aside from the fact that it's...damp, cramped, dark, and we are almost certainly walking in rat poop. Awesome. Castle: Don't forget the C.H.U.D.S Beckett: C.H.U.D.s? Castle: Cannibalistic Humanoid Underground Dwellers. These sewers are crawling with them. Beckett: You know, I kind of figured you more for an "alligator in the sewer" type of guy. Castle: There's alligators down here?
Castle: Well, the Old Haunt just reminded me of how vital tavern culture is in this town. I thought, why not open up a little tavern of my own? Beckett: So instead of buying a drink, you're gonna buy a whole bar? Castle: My way of giving back. Beckett: Yeah, to your ego.
Alexis: Can you believe my old grade school shirt still fits? Martha: Oh, like a glove, yes. A shirt, no.
