Dexter, Season 5

Debra:
You gonna introduce us?

Astor:
That's the one I was telling you about - his new girlfriend.

Dexter:
She's my tenant. Lumen, this is my sister Debra. Deb, Lumen.

Debra:
I didn't know he had a tenant.

Lumen:
Didn't know he had a sister. I'm gonna...go check on the girls.

Debra:
Seriously? That's your tenant?

Dexter:
Yes.

Debra:
Where's all her stuff?

Dexter:
She hasn't really moved in yet.

Debra:
But you know her well enough to trust her with your son.

Dexter:
It was an emergency. I thought the girls had been taken.

Debra:
Why are you keeping her a secret?

Dexter:
I'm not.

Debra:
Really? Cos at the station we asked you who you were spending all your time with. You didn't mention the hot blonde that's living in your house?

Dexter:
Didn't seem...like it mattered. Obviously she didn't take the girls.

Debra:
That's not the point. I'm not judging you. Believe me - I understand rebound as much as anybody. But don't you think it's a little soon?

Dexter:
I'm not on any rebound.

Debra:
Come on. She's your tenant - really?

Dexter:
There's nothing going on.

Debra:
Fine. I give up.
