Lost Girl, Season 1

Dyson:
I don't want to share you, Bo.

Bo:
What?

Dyson:
I don't want anyone else's hands on your body. I don't want anyone's mouth on yours. And I know this is the last thing you want to hear right now.

Bo:
Why wouldn't I want to hear that?

Dyson:
Because you're a succubus, Bo. It's not in your nature to be monogamous.

Bo:
I am fighting my nature for you, and I am more than just my species, and I don't see you out there running around howling at the moon and chasing rabbit all day.

Dyson:
That's a good point.

Bo:
I know.

Dyson:
Look, I've been through more relationships than you, and I know that lying about who you are and trying to change the person that you care about never ends well. I can be intense, I can be territorial, and God knows I can be muleheaded. But I'm also yours... if you'll have me.

Bo:
Dyson, you are an idiot. You've been mine for a very long time.

Dyson:
Well, you better be careful, 'cause wolves mate for life.
