The newly married pair talk about how Castle's mobster friend is actually a nice guy.

"Up until the point he guts you like a fish," Beckett replies to this.

Castle then introduces Beckett to Dino (Paul Ben-Victor), the mob boss. While Dino and his men are wary of the fact that Beckett is with the NYPD, Castle assures them that they need their help for a murder investigation.

"For you, Rick, I'm happy to help, and the boys are too," Dino says calmly as the clip ends.

This episode will also be a big one for Esposito (Jon Huertas) and Lanie (Tamala Jones), according to the press release for the episode.

"When an ER physician is gunned down in the street, Castle and Beckett soon discover that the victim was a mob doctor to a Mafia family run by an old friend of Castle's. Also, against the backdrop of Christmas, Esposito and Lanie reach a defining moment in their relationship," the synopsis reads.

Castle airs Mondays at 10 p.m. ET/PT on ABC.
