(Elena and Damon are talking about Katherine...)

Elena Gilbert: What was she like?

Damon Salvatore: She was beautiful. A lot like you in that department. She was also very complicated and selfish, and at times not very kind... but very sexy and seductive.

Elena Gilbert: So which one of you dated her first?

Damon Salvatore: Nicely deduced. Ask Stefan. I'm sure his answer differs from mine.
