- Katherine: (to Elena) "Do you really think that I want to take a road trip with you? America's most boring, self-righteous vampire?"
- Qetsiyah: (to Stefan) "I'm Qetsiyah-- that sane, rational, well-adjusted woman you seem to know so much about. Clearly you've heard the man's version of the story. The one where I'm a back-stabbing lunatic that ruined everything for Silas; a raging bitch-witch whose obsession with vengeance created a whole new dimension of suffering in the afterlife."
- Qetsiyah: (to Stefan) "I'm a complicated person... but Silas remains a simple man."

- Qetsiyah: (to Damon) "Silas had his true love and Stefan has Elena. We're merely the conflict that makes it interesting."
- Silas: (to Katherine) "You know, it's funny-- the love of my life looked exactly like you, and yet the mere thought of your face makes me want to vomit."
