The "spy" Richard Castle pretends to be is named "Steven Caldwell". Richard Castle tells this to Hans Brauer. Mitch Pileggi (Hans Brauer) played the recurring role of Colonel Steven Caldwell in Stargate Atlantis.
The Euros found in the trunk of the victims car are easily recognisable as fakes, since their proportions are completely wrong. They are far too high compared to the real Euros. About at least 1/3 higher than the real 50€ bills.
Castle: Uhm, well, with my book due, I was thinking it'd be a good time for us to take a break. Beckett: A break? Castle: Yeah. Well, God knows, you gotta be tired of me following you around all the time, and I really do need to get some work done. With everyone gone, I figure, why not just stay up in the Hamptons, you know? Get away from the city for a while. Beckett: Well, for how long? Castle: The summer at least. I thought this would be our last case.
Esposito: So... Castle's last case, huh? Beckett: Mm-hmm. Esposito: Ryan and I thought we'd do a little going away party. Beckett: Yeah. Well, it's not like he's leaving forever. Esposito: You sure about that? Why do you think he's been following you around all this time? What, research? The guy has done enough research to write 50 books. Look... whatever the reason is, I'm pretty sure it doesn't include watching you be with another guy.
Castle: According to this, half the kids in your building will be 16 and 17 year old boys. Alexis: Relax, dad. Each floor has a resident advisor who's 21. Castle: Oh, so the one person in charge is conveniently old enough to buy alcohol?
Castle: Oh! Look who's off duty! Beckett: Yeah, well Castle, I'm not all work. Lanie: Don't go into a drinking contest with her. She can take you. Castle: Thank You. Beckett: Oh, I don't need to drink to take him. Lanie: Ooh! What's got into you?
(Hans finds out Castle is not the person he was supposed to meet and grabs his shirt) Beckett: NYPD! Hands up! (Castle puts his hands up) Not you Castle! Castle: Right..
Castle: It's kinda like a tradition you know; bonfires, roasting marshmallows, telling ghost stories, sleeping late... We've done it since she was five. Beckett: Sounds nice. Kind of magical actually. Castle: Yeah, you know what? You should come. Oh! It's right on the ocean, there's a secluded pool, you could lay out, work on your tan. Beckett: Wow Castle. You're working really hard to see me in a swimsuit. Castle: If you are not comfortable in a swimming suit you can just skinny dip. (Beckett smiles to herself)
Michael Trucco (Det. Tom Denning) and Rick Worthy (Jason Fenn) previously co-starred together in Battlestar Galactica, playing Samuel T. Anders and Simon/Number Four respectively.

Season Finale
When Castle is told James Patterson is going to be late for the poker game he says "probably gives him time to write another book". Alluding to the fact that Patterson puts out a book about every other month. Then at the poker game guest star Patterson says: "Only one book a year, Rick?"
The film Castle is watching at the beginning of the episode is "His Girl Friday" (1940) with Cary Grant and Rosalind Russell. The quote they choose to use "We've got something between us nothing can change" is probably intended to describe the relationship between Beckett and Castle.
