According to spoilers, the serial killer will send a scary message directly to Danny, and there's a possibility that the killer is harbouring a grudge against Danny. The contents of the letter are yet to be revealed, but it is something that will put Danny in a foul mood throughout the episode.

Elsewhere in the episode, we'll see the Reagans gathering for an awkward family dinner. According to a preview clip obtained by Entertainment Tonight, the meal begins with Erin talking about her attempts at getting a judgeship.

A possible serial-killer case is assigned to Danny and Baez. Meanwhile, Erin considers becoming a judge; a mayoral candidate claims that Frank has been secretly investigating her spouse; and Eddie confronts her dad when he turns up in the hospital.
