Bridget Moynahan and Donnie Wahlberg are reprising their roles on CBS's Boston Blue episode, "L'Dor Vador," which features Erin Reagan as Assistant District Attorney for Danny Reagan. The episode also featured a scene where Erin and Danny were confronted by a serial killer named Abraham, who confessed to knowing the whereabouts of a missing Boston girl. Abraham then led them on a high-stakes journey to find out where he was holding the girl's captor. The pair explained the significance of the phrase "please don't hurt my family" in the episode, which was a reference to Blue Bloods.
