Leonard Hofstader was pissed. After getting hit by Penny with the baseball bat he was angry. He realised that he had nobody but that bitch Cara to blame. That damned bitch had cost him everything and for what, Sheldon Cooper. The name aroused rage in him. Sheldon fucking Cooper. And not only that but his so called friends Howard and Raj also were now against him.
In his rage Leonard would end up wandering near the shady areas of Pasadena, where his hotel was located. He had no idea of what to do next. While walking he would be stopped by a couple of rough looking men. One guy would stop him and taking out a gun said," Hey, where are you going?". Leonard got scared and replied," TO my hotel Room. I don't want trouble, here take my wallet". The man took his wallet, took out cash and gave it back to him.
Leonard after receiving the wallet would go to his hotel but after taking a few steps stopped. He would go back to the guy and speaks to him in a scared voice," Sir, would you mind if I asked you something". The guy asks,"What?" "How can i get a Gun?" The man relies by saying,"How much cash do you have?" "Not much in my hand but I have an ATM card and have about $2,000 there". The guy pauses and then says ,"For $ 600 you'll get a pistol with 16 bullets, a Smith & Wessen Sd Ve 9mm".
Leonard would give the man who said his name was Rodrigo the money and within half an hour receive the gun, loaded. Leonard was told how to use the gun and had about six of practice shots with it. He would hide the gun in his jacket and go back to Penny;s house with revenge on his mind. He reached the place within 15 minutes and would go up. He would knock on the door. The group was surprised as all of them were there and nobody else was expected. Penny asked who it was and Leonard replied that it was him. Penny said," Leonard, leave before we call the police". Leonard took out his Gun and undid the safety and replied,"Something of mine fell in your apartment, let me take it and i will leave". Penny looked around but found nothing. She replied,"There is nothing in here. Go away". "Well i dropped it, give me my thing and i will leave".
Sheldon opened the door and started ,"Leonard you ..." and a gunshot rang out. Sheldon stumbled back a few steps, clutching his hand to his abdomen. Penny ran to Sheldon. Everyone saw that Leonard had a gun. Leonard would quickly fire while others were in shock. While his aim was not good, his shots did do damage as Penny who was near Sheldon was hit in the right shoulder while Cara was hit in her throat. Bernadette was hit on her thigh and a bullet hit Stuart on the ear and one grazed his arm. With his bullets over, Leonard was standing above Penny and Sheldon. He would see Penny holding Sheldon and would hit her on the head with the pistol while calling her a bitch. Alice, Howard and Raj would go to restrain him and Leonard would also swing the gun at them catching Alice on her shoulder before Raj tackled him and Howard managed to get the gun.
Raj would call 911 and helped Alice before he saw Cara and got a shock. The ambulance and the police both arrived and Leonard was taken away to jail and Raj and Howard would go to the hospital with the others. Cara and Sheldon would be pronounced dead on arrival at the hospital. Penny would also later die due to head trauma. Bernadette, Alice and Stewart would go back to their normal life but they would be scarred. As would Howard and Raj.
Leonard would get the electric chair for the murders he committed. And as he was lead to the chair, Leonard would say." I am better than Sheldon fucking Cooper".
