Diana: I don't think that's bundling.
Matthew: Well, it is in France.

Matthew: That one was made by the tip of a broadsword during the hundred years war. Think of them like a map of my life.
Diana: I want to hunt down everyone who hurt you.
Matthew: My love. With you, my life has a beginning, a middle, and an end. When you're gone, my life will be over.

Matthew: We don't understand everything yet, but so far we've discovered that you have every genetic marker we have seen in a witch. We have the elemental markers of air and water.
Diana: Witch wind and witch water.
Matthew: Mmm hmm. You also have earth, which means you're likely, more than likely, to cast spells.

Ysabeau: You think that lighting a fire and pouring some wine will help them?
Marthe: He loves her, Ysabeau.
Ysabeau: They'll need more than love. The witches will think she turned her back on her own kind, and they will come. And when they come, her weakness will put us all at risk.
Marthe: She will find a way to use her magic to protect herself.
Ysabeau: Then she better stop behaving like some human and find a way, fast.

Gerbert: What is it? What can you see? Is Diana the witch from the prophecy?
Luisa: Beware the witch with the blood of the lion and the wolf for with it she shall destroy the children of the night.
Gerbert: I know that; I know. Speak to me or you will get no more of this.
Luisa: Two. Light. Dark.
Gerbert: There are two witches?
Luisa: One close.
Gerbert: Who is she, and where can I find her?

Ysabeau: Do you know what you have just done?
Matthew: If we're not welcome here, Diana and I will leave.
Ysabeau: Have I ever deserted you?
Matthew: No mamón.
Ysabeau: Then why would I now? You are my beloved son and you are now my daughter. Your fight is now my fight. If you have the courage to love my son, you have no need to fear your power. The women of the de Clermont family defend themselves, and you will be no different.

Diana: Tell me.
Matthew: If I do, they'll be no turning back. You have to understand.
Diana: Ysabeau made me understand. Tell me.
Matthew: From this moment, we will always be one. Diana, I love you.

Diana: According to her, you're a mix between Superman and Lancelot.
Matthew: Well, I try.

Domenico is a snake and Gerbert? Gerbert is unspeakable. It's long been rumored that he's kept a witch captive for centuries in his thrall. You keep away from them both.

Knox

Ysabeau: I told him I could take his suffering away and make him live forever. He was so out of his mind with pain, I don't think he completely understood what he'd agreed to.
Diana: If I could use my blood to save him, I would.

Ysabeau: Matthew's true love will always be Blanca; she gave him a son. You'll never be able to bear a child by him. In 1500 years, Matthew has never mated, and I didn't think he ever will. It's forever.
Diana: I will never leave him.
Ysabeau: Of course you will. Your life is fleeting compared with a vampire's. When you are long gone, Matthew will have to carry on living without you, just as he did with Blanca.

Matthew: Honestly, though, she, she is incredibly powerful. And she's clever and funny. She's full of courage.
Hamish: Don't fall into the trap of thinking for her.
