Ryan: I feel bad for Gates. My sisters could never work together. I tell you, when the two of them went at it-- Whoo!
Esposito: I wouldn't mind going at it with Gates' sister.
Ryan: Really? How'd you like having Gates as your sister-in-law?
Beckett: Ryan, you guys kept your wedding small. What was it -- like 100 people?
Ryan: Yeah, that’s all we could afford.
Castle: How did you contain the list?
Ryan (inhales deeply): I have a lot of relatives who hate me now.
Castle: Of course...I'm going to have to invite my mother and Alexis.
Beckett: Yeah, and my dad and aunt Theresa.
Castle: Right. Espo and Ryan, who will bring Jenny.
Beckett: Mm-hmm. Lanie.
Castle: Lanie. I'm going to have to invite the poker group.
Beckett: Yeah, Maddie.
Castle: Gates.
Beckett: Ooh! And Gates' family.
Beckett: U.S. Attorney for the Southern District. That's a really big deal.
Castle: Why hasn't Gates ever mentioned her before?
Beckett: I don't know, but there was definitely a subtle chill between the two of them.
Castle: A subtle chill? More like a polar vortex. I'm guessing something happened between them in the past. Something deeply personal that Gates does not want us to know about. I'll give you a dollar if you ask her.
Beckett: No way.
Casle: Come on, aren't you curious?
Beckett: Yeah, but I like my job too much.
Castle: We're in! Castle you've done it again.

  • It revealed that Gates has a sister name Elisabeth Weston who is the U.S. Attorney, which makes Weston potentially her maiden name(?) and this is also the first time we meet one of Gates' relatives.
  • In this episode, Castle and Beckett start making a guest list for their upcoming wedding.
  • When Castle and Beckett asked Ryan about his wedding from Till Death Do Us Part, he stated that he and Jenny had made a guest list and kept it small and simple (because that was all they could afford). As a result, he now has a lot of relatives who hate him.
  • Ryan has two sisters, since he mentioned them in A Rose for Everafter and Once Upon a Crime.
  • Ryan told Castle that roller coasters make him sick.
  • Noree Victoria who played Secretary is Penny Johnson Jerald's sister.
  • Beckett's Aunt Theresa is mentioned again when Castle suggests that she should be taken off the wedding list after having made a post that was less than flattering about Castle on her Facebook page when it was reported on page 6 that Castle had been seen canoodling with his ex-wife and publicist, Gina, in Limelight. According to Beckett, Aunt Theresa did take the post down.
