Melissa in Omaha: Gimme something on Castle that doesn't have to do with the couple's relationship.
As you wish! The 12th episode of the season, entitled "Under the Influence," finds Beckett and Castle on the case of a murdered DJ. Among their list of suspects: Regina Cane, a fading pop star desperate to stay in the spotlight; an image-conscious rapper named Bone Thug; and an orphaned 14-year-old street kid with a growing rap sheet. Look for Esposito, who didn't exactly have the easiest upbringing himself, to take a special interest in helping out the troubled teen.
