Rebekah: I know you hate me, but what's done is done.
Klaus: What's done is never done. It remains within us, the story we tell ourselves so we know who we are. A vicious father, a bastard son, and the sister who betrayed him. Perhaps it's time for a new story.
Elijah: Niklaus, I understand your anger, but I implore you, be better than him. Do what he could not. Demonstrate the grace of mercy rather than this petty cruelty.
Klaus: You ask me to show mercy to one who has wronged me? You really don't know me at all, do you, brother?
