Susie Chang: Dr. Isles is the first president elect in the field of forensic pathology .
Detective Jane Rizzoli: Yes, and the first whose patients are all dead .
Susie Chang: [Taking the cake as the celebration is interrupted]
Okay, I'll just, eh, take this to the fridge .
Susie Chang: not the morgue fridge .
Detective Jane Rizzoli: If that goes anywhere near a person with a toe tag, I'll know it .
Susie Chang: I understand .
Detective Jane Rizzoli: I'm watching you Chang! .
Susie Chang: The morgue fridge is the only thing big enough to fit this cake in .
Angela Rizzoli: Dead man tell no tales .
Detective Jane Rizzoli: Well, he is shot, right, Maura? He wasn't run through with a spear or something? .
Dr. Maura Isles: Well, I need to autopsy to confirm the cause of death, but these wounds are consistent with a gunshot, yes .
Detective Jane Rizzoli: Well, just because it is a professional killer, doesn't mean it's a professional hit. Ned wasn't even supposed to be here .
Detective Vince Korsak: Professional killer, random target? .
Detective Jane Rizzoli: Don't day the R-word! It's bad for morale! .
Dr. Maura Isles: You know I think he has clinical lycanthropy, usually brought on by schizophrenia or a psychotic break .
Detective Jane Rizzoli: Do I need a tattoo on my forehead that says: "What does that mean, Maura?" .
Dr. Maura Isles: Oh! I assumed you were just shocked into silence because his condition is so rare .
Detective Jane Rizzoli: No! .
Nina Holiday: Turns out custom reloaders are very cooperative people .
Nina Holiday: after I threatened them with a warrant to seize all their chemicals to search for unregistered tags .
Detective Jane Rizzoli: Hey, did you get my text? .
Dr. Maura Isles: You said you were coming down .
Detective Jane Rizzoli: Yeah, and then I said: "scratch that, I need you to come upstairs and talk to Teen Wolf" .
Dr. Maura Isles: Oh .
Detective Jane Rizzoli: Well, after that it's just variations of "where the hell are you?" .
Dr. Maura Isles: These emoticons don't deserve to be used in such disturbing ways .
Detective Jane Rizzoli: Gets the point across, doesn't it? .
