-Elijah Mikaelson is the brother of Klaus. A part of a family of vampire/werewolf hybrids banished from New Orleans a century ago.
Elijah: [to Sabine] You ever experienced something so profoundly wonderful that when it was taken from you your life felt unbearable?
Sabine: Yes, I have felt that. And I have the scars to prove it.
Elijah: I believe that when you love someone and that person loves you in return you're uniquely vulnerable. They have a power to hurt you that's like nothing else.
If the definition of insanity is doing the same thing repeatedly and expecting different results then surely my quest for your salvation ranks me as one of the maddest of men.Elijah
