Integra: Yes, Father?
Arthur: Vampires have no concern for human life. They will kill everyone close to you without a second thought.
To fight them effectively, you must be prepared to match them. You cannot show them mercy. They will show you none. Be ready for that, Integra.
Integra: But, Father, that means people will die…
Arthur: People will always die. As long as vampires exist, they will kill people. You can’t be afraid to let one person die if it will save many others.
Integra: Did you ever have to let an important person die, Father…?

Integra: 6 AM? And I’m awake?!
