Katherine: "Better you die than I."

Rose: "Being in love with your brother's girlfriend must be difficult."

Damon: "I'm not in love with anyone."

Rose: "Wanna try that again?"

Caroline: "You have a friend?"

Stefan: "You say that with such a discouraging amount of surprise."

Katherine: "Witches and their spells. So many ingredients. So many people to sacrifice."

Katherine: (To Elena) "He killed them. My entire family. Just to get back at me for running. Whatever you do to escape Klaus, he will get his vengeance. Your friends, your family and anyone that you`ve ever loved."

Elena: (To Stefan) "It`s not just me that's in danger. It's Caroline and it's Tyler and it's Bonnie... They're all part of breaking the curse. I can't blame anyone else anymore. Because it's not because you came into town, or because you and I fell in love, that's not why everyone that I love is in danger. It's because of me. Everything is because of me."
