We've been looking for answers in the wrong place the entire time. The answer doesn't lie with vampires; our human genes hold the key.

Miriam

Gallowglass: Philippe asked me to look out for you.
Diana: Look out?
Gallowglass: And make sure that you made your way to Matthew.
Diana: You would have waited centuries.
Gallowglass: I gave him my word.
Diana: He had no right to ask that of you.
Gallowglass: Diana, I did it gladly.

Weston: Why are you helping a witch?
Agatha: The same reason that you should be, Timothy. The book is our chance to prove that demons matter, too. We have faced centuries of prejudice because no creature or human has even tried to understand us.

Diana: Timothy, we need to prove to The Congregation that their cruel and antiquated laws are the reason that creatures are suffering. This page will complete The Book of Life, make it whole again.
Weston: You don't have to explain it. I know exactly who you are. You're the one who will learn how it all began -- the blood, the death, the fear, and the one who can put a stop to it for once and for all.

Diana: Where's Matthew?
Sarah: Diana, I was there for Rebecca when you came into this world; I'm here for you now. We can do this.

Matthew: Marcus, I deeply regret what I did her. I'm sorry.
Marcus: Thank you.

Matthew: I believe that we should live with truth and hope, not fear.
Ransom: Pretty words, the last thing we need.
Matthew: Tell me what you do need.
Ransom: Remorse, Matthew! If I could just believe for one second that you comprehend what we lost.
Matthew: I am sorry for what happened
Ransom: NO!! It didn't happen to us! It was done to us! Now, if you can't understand that.
Matthew: Malachi Smith. Friendly, big smile. He was walking down Bourbon Street. He stopped for a cigarette, and I killed him. Suzette Boudreaux. Beautiful blonde hair. Spoke immaculate French. I pretended to be lost. She gave me directions. And I killed her. Sun Gren LaChalet. She would often visit the San Luis Cemetery. Someone she cared about was laid to rest there. And on a rainy Sunday afternoon, that's where I killed her.

Marcus: Matthew is trying to find another way, and that starts with a cure to blood rage. You can help us figure out why you and I aren't afflicted. You can't change what's already happened.
Ransom: But he can own it, Marcus! Just by being here, he's opening wounds that have barely had a chance to heal. I'm glad Matthew's found his conscience, but I can't help thinkin' it's a couple centuries too late.

Diana: So, Father. Who do you trust with the book? A member of The Congregation or a member of your own flock?
Hubbard: I need to know that my flock will not be collateral damage in this struggle the de Clermonts are engaged with. Can you give me that?
Diana: No. But I can promise you this -- if we lose, any chance we creatures had to live in peace will be gone, and there will be reason for Knox or Gebert to keep up the pretense that we are all equal. They're already using The Covenant to divide us.

Miriam: New Orleans was never going to be easy. What Matthew did there, it was carnage. It ripped Marcus's family apart.
Chris: But you can't choose your family, right?
Miriam: Well, that's not strictly true for vampires. You just have to live with your choices for a long time.

Jack! You control the rage; the rage does not control you. Remember what we practiced. Stay in the present. Find your focus.

Matthew

There will be no scion. Go home.
