Your other personalities don't count.
Now this is where it actually gets a bit serious.. even though I wasn't taking her seriously she actually did.
Nighttime. Patrick walks by a courthouse on his way home. Steam rises from underground vents. He walks through an alley, a black shadow under a pale streetlight. He stops and looks behind him, to see a homeless man by some piles of trash. “Hello. Pat Bateman. Do you want some money? Some food?†He starts taking out some money. “I’m hungry,†says the bum. “It’s cold out too isn’t it? If you’re so hungry, why don’t you get a job?†The bum says he lost his job. “Why? Were you drinking? Insider trading? Just joking.†He asks him his name, and the bum says his name is Al. “Get a god-damn job, Al! You have a negative attitude. That’s what’s stopping you.†He promises to help him get his act together. Al tells him he’s a kind man. He puts his hand on Patrick’s arm, and Patrick pulls it off, visibly disgusted. “You know how bad you smell? You reek of shit. You know that?†He laughs, and then apologizes. “I don’t have anything in common with you.†He bends down and opens his briefcase. “Oh thank you mister, thank you. It’s cold out here…†“You know what a fucking loser you are?†Patrick suddenly takes a knife out of the briefcase and stabs the bum three times in the stomach, then pushes the shocked man to the ground. The dog barks at Patrick, so he stomps it with his foot, hard enough to kill it. He picks up his briefcase and walks away down the alley.
A health spa. A young Asian woman rubs some lotion on Patrick’s face. She compliments him on his smooth skin. Later, another Asian woman gives him a manicure. “I have all the characteristics of a human being. Flesh. Blood. Skin. Hair. But not a single, clear, identifiable emotion, except for greed, and disgust. Something horrible is happening inside me, and I don’t know why.†He is lying in a tanning bed now. “My nightly bloodlust has overflowed into my days. I feel lethal, on the verge of frenzy. I think my mask of sanity is about to slip.â€
