Sanctuary, Season 3

Nikola Tesla:
You have a Sasquatch for a butler and you travel the world with history's most notorious murderer, and now you don't feel safe? Helen, green is not a good color on you.

Helen Magnus:
Don't be ridiculous.

Nikola Tesla:
She's intelligent, powerful, remarkably well- preserved for her age, everything I look for in a woman, and unlike someone I know, she's actually interested in me.

Helen Magnus:
I'm not engaging in this childish conversation.

Nikola Tesla:
The more you deny it, the truer it is.

Helen Magnus:
Oh, that's an excellent scientific method.

Nikola Tesla:
Thank you.

Helen Magnus:
Really, really good--

Afina:
I can hear you, you know. Vampire, remember?
