-1A/N: Casey and Derek aren't step sibs in this story they are best friends. Sorry its so short

"David what are you doing," Casey cried as she felt the metal get pressed against her skull.

"You aren't suppose to be talking to him and I told you if ever did again I would have to punish you," David said smirking and pushing the gun further into her head. The feeling of the gun pressed hard against Casey's skull made her wince from pain.

"David we can talk about this just let Casey go," Derek said trying to stay calm.

"You want to talk fine we can talk but I'm not letting her go," David said pulling his arm tighter around Casey's waist. As David pulled his arm tighter around her waist, Casey elbowed him in his stomach. Casey's punch knocked the wind out David and he released Casey from his grasp.

"You bitch how could you choose him over me," David said as tears fell from his eyes.

"That's easy he never threatened to take my life," Casey said as she clung to Derek's hand tightly. When Casey said this David pointed the gun at them.

"If I can't have you know one will," David said as he pulled the trigger and ran down the street. When David pulled the trigger Casey fell to the ground clutching her arm in pain.

"Casey are you okay," Derek asks pulling out his cell phone and calling 911.

"My arm hurts really bad Derek," Casey said curling up in the fetal position.

"It's ok the ambulance is on the way just stay with me," Derek said sitting down and pulling Casey into his arms.

"I will try," Casey says but as she mutters the last word she passes out.

"Casey Casey come on wake up," Derek says while shaking her.
