[Mary fishes out a blood-soaked towel from the toilet that overflows with blood]

Jesus! How'd that get in there!

After I killed that kid, I used that towel to clean up the mess, and then I stuffed it down there.

Norman, you couldn't have killed that kid. You were locked in the attic.

It wasn't locked! You said so yourself.

Norman, stop talking nonsense! I'm telling you, you did not kill anyone.

Then how do you explain all this blood?

[Mary does not reply] [shouts]

Well?!

I can't. I mean... I don't know.
