The Vampire Diaries, Season 5

Katherine:
I want to know why you made up that fake story about your mom.

Nadia:
It was a test. You failed.

Katherine:
I knew it was a fake story. By 1645, I'd been running from Klaus for a century and a half. There's no way any of his minions would have mistaken anyone for me. But you know how my brain works, right? So you must have known that I wouldn't have fallen for that sob story.

Nadia:
I wanted to get under your skin, and it worked because here you are.

Katherine:
What kind of sick game are you playing?

Nadia:
It's not a game, Katherine. You did kill my mother, but it wasn't Paris. It was in a little cottage in England, and it wasn't 1645. It was April 6, 1492, and she was all alone, exiled by her family two years earlier. You stuck her head in a noose, pushed her off the chair, and snapped her neck.

Katherine:
Who are you?

Nadia:
My name... is Nadia Petrova... and you are my mother.
