Dexter, Season 6

Jonah:
Get the f*** out of my house.

Dexter:
Show me where it happened, Jonah. Your father killed your mother here, on this staircase?

Jonah:
Police can be here in three minutes.

Dexter:
Here is where her body was, and here is where you cleaned up your mother's blood.

Jonah:
You're a sick f***, you know that?

Dexter:
Where'd you fight your father off? It was here, right? When you took the weapon from him and hit him - chasing him off?

Jonah:
Yeah

Dexter:
Swinging at him the whole time.

Jonah:
Yeah, I was. Yeah.

Dexter:
If that were true, there'd be blood on the wall, and on the ceiling here. But there's no spatter here.

Jonah:
Hey, that's because I cleaned it up. Now go!

Dexter:
With bleach?

Jonah:
Yes.

Dexter:
Not on this wall - because there was no blood on this wall, because your father was never here. I know for a fact that Trinity did not kill anyone in this house.

Jonah:
Is that because you killed him?

Dexter:
Yes - just like you killed your mother and your sister.
