Klaus is not in love with Hayley but has come to see her as a part of the Mikaelson Family. She is carrying his child and in the beginning they had a rocky start but eventually they grew to understand each other and even protect each other. However, ever since Elijah's return, Klaus senses Hayley's attraction to his noble brother, which makes Klaus feel left out and threatened. Klaus has left the Plantation to live in The French Quarter and he took Hayley with him, but it wasn't her choice so much as an ultimatum. You think they can patch up their friendship?
