Klaus, Hayley and others in “Unfinished Business”

Klaus

I assure you, love, that there is not a thing in the world that will matter enough for me to waste even thirty more seconds of my time. Elijah, what madness is this?

Klaus... You need to listen to them.

Klaus

You're all out of your minds if you think some liquor fueled one-night stand--no offense, sweetheart-- means a thing to me.

Sophie

Marcel may be able to keep us from practicing real magic in this town, but as keepers of the balance, we still know when nature has cooked up something new. For example, I have a special gift, of sensing when a girl is pregnant.

Klaus

What?

I know. It's impossible.

Klaus

What are you saying?

Elijah

Niklaus... the girl is carrying your child.
