When Rebekah was looking for a loft with shutters in the fourth episode, he had a question.

Klaus Mikaelson: It turns out my brother is even more depraved than I am. He is the noble stag no longer, indeed an altogether different beast is crepeing through the cracks. And you have also altogether failed in your representation of me because there is one thing you never thought me capable of. Forgiveness. You, Finn, have remained a boar for centuries but here is where your true fault lies. You never learned that the bonds of family far outweigh anything else. Such bonds trump petty jealousies, they overcome great feuds, and yes, they even allow one monster to pardon the great sins of another.

Klaus Mikaelson: [to Kol and Finn] I'd prefer you both to join me against our mother, but I'll happily settle for one or the other. Either way, if you continue to defy me, your lives will be reduced to an unending sequence of agonizing torture. So, which is it to be?
