- Corpse: [to the tune of London Bridge is Falling Down] What's that barking? It's all starting. Like a row... of dominoes. Can you stop them falling? Someone's due a mauling. Here it comes, the wolf-shaped gun. Annie, listen... here's your mission. Mitchell's toast. If you're a scaredy ghost, come to Purgatory, stop shit getting gory, or the big bow-wow... ends your story now.
- Mitchell: They're going to kill me, Annie. They're gonna kill us all.
- Annie Sawyer: No, you don't know that.
- Mitchell: They're frightened of us.
- Annie Sawyer: They should be.
- McNair: Tom, if you're reading this, then I'm dead. Somewhere in this house is a vampire. He's the one I've always been searching for. He was there when I became this creature, and tonight I tried to kill him. If I had, I would have been able to stop - but I wasn't doing this for me, or the man I killed two months ago, or even your parents. This was for you, my Tom. This must be the final act.
- McNair: Tom, I want you to live a different life now, one that's decent. You see, we've lost everything that was harmless and mundane. When I sat down to write this, I realised I'd forgotten how to hold a pen. It's so long since I did something so ordinary. I was selfish. I turned you into a weapon for my own war. The things I've asked you to do, they make me ashamed. Let it end. I want you to be human now. Stop this chaotic, violent life. Make this the end of that story. I died tonight but don't avenge me. It's getting dark. I have to go. Always know that I love you, Tom. I wish I really had been your father.
- [McNair's grave marker: "A warrior, a father."]
- Mitchell: [awakening inside a fight cage] Why have you brought me here?
- Herrick: Hm, surely, WHO have I brought here is more apropos. I mean, one minute you're letting George tear my head off for the sake of humanity and the next you're massacring twenty of them in a train carriage. I mean, talk about fickle.
- Mitchell: Yeah, I wouldn't expect you to understand. Your character's always been pretty consistent.
- Herrick: I think that was a dig!
- Herrick: George, did you know you've been living with a celebrity the last few weeks? Oh, it's not me. Um... You're so sweet.
- Lia: [referring to Nina coming to the afterlife] You know, I think we'd be great friends, us three.
- Annie Sawyer: Yeah. Yeah. All the murdered girls, mm?
- Mitchell: You recruited me. You led me into this unbelievable world - and I know I've done some terrible things, but I've seen some extraordinary things, too. I have more memories than I deserve, Herrick, and that's because of you. And so, in return, I want to give you this.
- [Looking out, the dawn of a new day breaks from across the North Sea]
- Herrick: Look at this world. How does it make you feel knowing that soon all this will be ours?
- Mitchell: Don't you understand? It always was.
- Edgar Wyndam: [switching off the recording of Mitchell's arrest] A nation exhales as the killer of the Box Tunnel Twenty is finally brought to justice. In other words, that was the sound of someone else doing your job. My name is Edgar Wyndam, and as of twenty-six seconds ago, you are all unemployed. If you have a phone in your hand or a piece of paper or a file, put it down. Make your way to the exit. You will be searched on the way out. And when your wives and husbands ask why you are back so early and so shamefaced, you tell them this: "Our superior officer disappeared. An arrest was made, but then the arresting officer and five more police were killed at the suspect's house, and then the suspect disappeared." You tell your families "I am here because I failed."
- Annie Sawyer: Can't believe how quickly Nina's recovered.
- George: Yeah, well, it's the one advantage to being a werewolf, I guess. You don't survive shattered bones and major organ failure every month without toughening up a bit.
- Mitchell: [explaining his special request of George] He has to kill me because he has to disown me. You've all become corrupted by me, but George most of all. He suspected more than any of you, and so he had to choose between his love for me and his ethics - and I let him choose me.
- Edgar Wyndam: And then there are the history makers - a werewolf impregnated by another werewolf. Ugh. We've never seen the like. The others want you culled. I'm the curious type. I want to see exactly what it is that's going to pop out.
- Edgar Wyndam: I want you to pass on a message to every werewolf, every ghost, every vampire that you meet. You tell them the world is under new management now. It is year dot. You tell them this: The age of the vampires has begun.
