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.
Davina: You don't look well.
Elijah: Well, only this morning I had a mystical dagger embedded in my chest so I'd say I'm holding myself together quite well.
