In the previous episode, defence lawyer Caleb ruthlessly exposed the mystery novelist's history of memory losses, thereby proving him a weak witness for the murder of a well-regarded reporter named Sadie. The lawyer proves that the murder was in fact a crime of passion and that Sadie was killed by her husband when he discovered that the reporter was in a same-sex relationship with Nina.

Castle saw Nina running over the dead body of Sadie and assumed that she killed her. Post the trial, Ryan and Esposito praise Caleb's calibre as a criminal prosecutor but Rick remains shocked after being exposed to his painful past.

In the upcoming episode, he and his detective wife will investigate the murder of a Russian diplomat and during the investigation they become entangled in a web of crime and punishment.

Season 8 is lacking in Caskett romance but fans need not have to wait more as co-showrunner Alexi Hawley has hinted that jealousy will bring them back to their magical romantic best in episode 16.

"in [Episode] 816, we will be doing a little Beckett/Lucy/ Castle [interaction], a bit of jealousy," Hawley told TV Line.
