The Vampire Diaries, Season 5

Nadia:
In 1864, there was a vampire roundup in Mystic Falls.

Katherine:
Was there? I'm bad with dates.

Nadia:
Word on the street is that you sold out many vampires, including your best friend Pearl and her daughter Annabelle.

Katherine:
I was running from Klaus. I needed to jet solo. I threw a couple of vampire names on a hit list. Sue me. I also impersonated a teenager to get my ex-boyfriends to make out with me, staged a fake fight to trigger my lover's werewolf curse, ooh, and I chopped off this douchey guy's fingers with a butcher knife once. That was cool.

Nadia:
What about ripping a mother away from her daughter? Having her killed for your own benefit?

Katherine:
What are you getting at?

Nadia:
Now a little bit about me. I had myself turned into a vampire to hunt you, to even the playing field, to track your every move for however long it took me until I found you, and I did this because you killed my mother. It happened in Paris, 1645.

Katherine:
I go to Paris for shoes. The shoes I remember. Everything else requires a few more details.

Nadia:
Her name was Lily Atoma. You were on the run from Klaus. She took you in, but when his minions show up, you pointed at my mom, and you said, "That is Katerina Petrova. She is the one you want." So they took her away.

Katherine:
You were never going to let me go, were you?

Nadia:
No, but I'd hate for you die on an empty stomach.
