Richard Castle: Twin girls are born and put up for adoption. Odette goes to a wealthy, loving family, Barbra, not so lucky. She gets bounced around from one foster home to the next, always knowing, deep inside, that she was meant for something better. Then, one day, the two of them meet on a train bound for Miami. The connection is instantaneous. In two days they learn everything there is to know about each other. And Barbra can't help but think, "If only I had landed in the lap of luxury like Odette, I could have been anything I wanted to be."
Kate Beckett: Are you suggesting that Barbra purposefully caused the derailment to take over Odette's life? With what? Her crazy Wiccan powers?
Richard Castle: [excited] Oh... Wow! That would be an incredible twist! But no. No. The accident happens, Odette is killed, Barbra survives. And in the midst of all the chaos and rubble, she sees her chance. She switches identification with Odette, and she changes her destiny. In one move, Barbra builds herself a better future. A perfect life.
Kate Beckett: Until she was murdered a year later.
Richard Castle: Yeah, well, separated twin stories never end happily.
Richard Castle: Except 'The Parent Trap'.
Javier Esposito: Maybe Castle's right. I mean, since we're going to be there, we might as well consider the Sapphire as a *potential* bachelor party venue.
Richard Castle: I'm so happy you said that, because there are a number of establishments down there that cater to bachelor party events. I think maybe we should take a little sampling.
Kevin Ryan: No, no, no. We are not sampling any clubs.
Javier Esposito: What? Come on, bro. Why are you stalling us on this?
Kevin Ryan: Look Javier, I...
Kevin Ryan: I got some bad news.
Kevin Ryan: I had to ask Jenny's half-brother, Nelson, to be my best man.
Javier Esposito: Nelson?... That guy I met at your birthday party? 16, with braces? Couldn't stop talking about being a mathlete?
Kevin Ryan: It was a family thing. I-I didn't have a choice.
Javier Esposito: Yeah, you did.
Richard Castle: No, actually, when it comes to weddings, you don't.
Richard Castle: Trust me. You do not want to start a marriage with a family feud.
Javier Esposito: This sucks.
Kevin Ryan: I know.
Javier Esposito: And I was gonna give you an awesome send-off, bro.
Kevin Ryan: I know.
Richard Castle: Well boys, I'm sorry. I'm sorry it had to come to this. I didn't want it to, but it looks like we have no choice. There is no other way. IBPWOC. Impromptu Bachelor Party While On Case.
