Klaus and Mikael in “Unfinished Business”

Klaus

So Mikael If you're going to kill me, then get on with it.

Mikael

Au contraire, Niklaus. Some things remain unsaid. For instance, you were right to be proud of your achievement here. As I walked the streets, your name was spoken of in reverent tones by the city's finest. So after I kill you, I will remain here in New Orleans until every last person who remembers you is dead. The deeds of the mighty Klaus will be remembered by no one. And you, boy, will simply never have existed.
