Caroline: "Probably off somewhere doing bad things to good people."

Rebekah: "There has to be more to this dress."
Stefan: "There’s not."
Rebekah: "So women in the 21st century dress like prostitutes, then? I got dirty looks for wearing trousers."
Klaus: "You wore trousers so women today could wear nothing."

Katherine: (to Stefan) "I’ve heard about that sister. Be careful. She’ll ruin you."

Damon: (to Bill) "So, Bill, I hear you’re into the whole daddy-daughter vampire-torture thing."

Gloria: (to Klaus) "You’re harshin’ my juju."

Rebekah: "I am not a brat!"
Klaus: "A thousand years of life experience says otherwise."

Tyler: "You want me to kick his ass?"
Caroline: "Yes. I mean, no. I bought him the shirt he’s wearing and it was really expensive."

Stefan: (about the other Originals) "Why don’t you un-dagger them?"
Rebekah: "Because he would hunt me down and kill me. He’s a vindictive little bastard, my brother."

Alaric: "You killed me."
Damon: "You pissed me off."
Alaric: "You killed me!"
Damon: "Ric, no hard feelings, alright? I was on a bit of a tear, and everyone was trying to tell me how to behave."

Damon: "Can't we just kill him?"
Liz: "No, Damon. He's Caroline's father."
Damon: "He sounds like a douchebag to me."
Liz: "Yeah, well, just 'cause you and I are on okay terms, doesn't mean I'm suddenly a big advocate for your lifestyle."
Damon: "Is that what you told him when you two got divorced?"
