A/N: You know when you're listening to music and you doze off and have a dream kind of related to the song? I did this with March of The Pigs by Nine Inch Nails, and this is what came out. It's probably the darkest thing I've ever written- enjoy...!
Disclaimer: The only thing I own is the box set- I don't make any money out of writing this stuff. I just do it for the lulz.

Leonard didn't like to brag, but he was a great actor.

The move from New Jersey to Pasadena had been a thought-over decision. The decision to move in with Sheldon, however, wasn't. He'd thought that he'd found a kindred spirit in the tall man- but he hadn't. Sheldon was not like him, he was just another OCD guy with an antisocial personality disorder. He'd told Sheldon time upon time that he was mad- but he wasn't, because his mother had had him tested.

Leonard smiles cruelly. His mother had never had him tested. Good thing, too.

That's what it all relates back to, in the end. His mother.

The two are more alike than anyone wants to admit. Leonard isn't willing to say he was abused, but he was neglected. He wonders briefly if it is genetics that has made him how he is, but really, who cares about the causes?

Leonard continues to dwell upon his childhood as he sits down on the sofa. Still not in Sheldon's spot. Never in Sheldon's spot.

He looks over to his roommate, in the kitchen. No matter the causes, these are the effects.

The thermostat. The thermostat was the short term trigger, his family and history were long term ones. He'd worked so hard to keep people from knowing his story. Everyone had believed the lies, even Penny. Leonard laughs as he thinks of her. Really, his acting around her had never been better. She'd believed every word that came out of his mouth.

Back to the thermostat. It was abnormally cold for October, but still Sheldon refused to change the temperature of the flat to it's winter setting. There'd been a flaming argument about it, and it was a damn good thing that Penny had been working, otherwise she'd have come to investigate. And then everything would be fucked.

"Sheldon, it's freezing in here!"
"But the average temperature has still not reached the average temperature for winter- ergo it is not winter!"
"Have you factored in climate change? It's possible that you-"
"Of course I factored in climate change, what do you think I am, a five year old?"
"You're acting like it!"

Leonard had retired to his room. Sheldon was provoking him- he knew it. He had tried to contain himself, tried to stay the calm, quiet Leonard that everyone knew him to be.

Sheldon had ruined that.

It was a red mist moment. Sheldon was still in the kitchen. Leonard had silently stepped up behind his roommate, and, with a movement quick as lightning, Sheldon slumped over the counter.

Leonard smiled, standing up as he remembered the moment. He circled around to the kitchen and stared at his best friend. His unseeing eyes stared back as blood dripped steadily into the sink from the gash in his neck.

"Any last words, Dr. Cooper?" Leonard laughs. He might leave the stain there. His now-ex roommate would have hated it. He looks down at himself. "I have ruined this shirt." He says to himself. Time for a shower, and this time there wouldn't be an obsessive roommate yelling at him to wash away his dead skin cells, and to preserve the hot water.

Leonard was a great actor, and he was sure he could pull this off.
