Matthew: I haven't lost control of myself for a very, very long time. I trained myself to hold the blood rage back, and I used genetics to try to understand it, try to find a cure.
Diana: Darling.
Matthew: It's Ysabeau who carries the honors. Luckily, she's spared of its effects. Luisa and I are not so fortunate. This is why we can never be truly mated.
Diana: Do you really think that I would ever walk away from you, my love, after all we've been through?
Matthew: This was but just a glimpse. You have no idea what I'm capable of. I'm a killer, Diana, and I've killed thousands. I was Philippe's weapon. He used me to eradicate the disease.
Diana: He made you his assassin.
