Jake thought of an obvious choice. Melissa. Why wouldn't he want to use it on her? This'd be a great use for the gun! "I'm using it on Melissa!" He typed in a few settings, and headed downstairs, waiting for his sister.
About 20 minutes later, Melissa came in. "Twerp! I'm home!", she yelled. "Hello, sis.", said Jake, as he steps out of the shadows. "What are you doing down here? You aren't waiting for me, are you?" "I am. I'm gonna do something to you. As payback, for the total bitch you've been to me." "What? Are you serious? You're, like, 4 years younger than me. I could probably kill you!" Jake smiled, and pointed the gun at her and fired.
