Back at the station Korsak finds out that he was passed up for the Sergeant by Joey (Donnie Wahlberg), an old rival of Jane's. While getting ready for a family dinner, Angela confesses that she thinks Frank needs Frankie to be part of Rizzoli & Sons. She wants Jane to tell him all of the things that she missed. Before Angela can finish Jane gets called in for another strangling victim. Maura and Jane are both worried, because it's the second strangling in one day. While finding the identities of their victims, Korsak notes that they share the same names as two of the victims of the original Boston Strangler, believes that the Boston Strangler is back, and that he wasn't really caught like everyone believed. During dinner with her date, Maura begins to analyze her date, and diagnoses him with Marfan's Syndrome, when he hears this, he runs off.
