Yes. We can be killed ... if you try hard enough.

Matthew

Diana: Were you an alchemist?
Matthew: No. I inherited those from my brother. He was fascinated by science with magic, magic with science. He never knew which way around it was.
Diana: I'm not sure either, to be honest. That's why I'm drawn to it.

Matthew: Did you cast a spell to call the book up?
Diana: No. No. No, I've never been very good at spellcasting.
Matthew: Well, then, perhaps there was a spell on it and you just happened to meet its conditions.

Diana: Living without magic isn't bad. I've survived without it.
Matthew: Well, that's not quite true. You use it all the time. You can feel me when I look at you.
Diana: It feels cold, like ice growing under my skin.
Matthew: Witch power is in your blood, it's in your bones. You were born to be a witch just as you were born to have blonde hair and those blue eyes.

Diana: And you?
Matthew: I was born human. We didn't keep track of birthdays back then, but I'd estimate it was in 500 and then I was reborn as a vampire in 537.
Diana: The things you must have seen.
Matthew: Mmm. And done.
Diana: Would you like to have dinner with me tomorrow?

Miriam: Certainly you're worried about the Bishop blood. I certainly have.
Diana: What will this tell us.
Marcus: Your inherited traits as well as where you've come from. From your DNA, we can trace you back to one of four witches...
Matthew: What the hell are you doing? If any vampire is going to take her blood, it's going to be me.

"Alchemy exists to transform mortals from a state of suffering to enlightenment." I didn't know into all this.

Agatha

Matthew: Hello, Miriam.
Miriam: You're craving her.
Matthew: Miriam, how I feel about Diana Bishop has absolutely nothing to do with you.
Miriam: She's a witch. You're a vampire. You know the rules. It's forbidden by the terms of the covenant.
Matthew: The Congregation is not going to enforce a four-thousand-year-old rule.
Miriam: Does Diana even know about it? Because Marcus doesn't seem to think so.
Matthew: Bye, Miriam.

Peter Knox: Expecting someone?
Diana: Get out of my rooms!
Peter: You're feeding him. You shy away from us and yet you seek out vampire company.
Diana: I'm not a bigot like you.
Peter: Just like your father, so open-minded that he put himself and your mother in mortal danger.

Diana: You don't breath much.
Matthew: Well, our hearts don't beat. [pause] Very often.

Matthew: I thought you knew about vampires. That's why you invited me to dinner.
Diana: I probably know a little less than most humans do.
Matthew: Most legends about us were dreamed up by humans.
Diana: Black hats, and bats, and brews.
Matthew: Yes, somewhere in all those stories there's a speck of the truth, something that frightened humans and helped them to deny that we're real.

Matthew: What do you taste?
Diana: Flowers and spice. You?
Matthew: There's violets in there. The purple sugared ones. Elizabeth Tudor absolutely adored them. Ruined her teeth. Also, blackberries from hedgerows, cigar smoke, red currants, and brandy. I could go on.
Diana: What would I taste like?
Matthew: Don't ever say that to me.
Diana: I only asked to understand.
Matthew: It would only take but a moment. You wouldn't be able to stop me if I struck, and I wouldn't be able to stop myself.
Diana: I'm safe with you.
Matthew: [grabs her] The smell of you… Willow sap. Chamomile honey. Frankincense. Lady’s mantle. Ancient things I thought I’d forgotten. It’s not only your scent. I can hear your witch’s blood moving in your veins. When I touch your skin and it rushes to the surface.
