The little numb feeling in your stomach

Rib Cage

I made it to the cave and looked at the screen again. I couldn't see anything but black.... A few seconds later (which felt like eternities) the screen shuffled with light here and there and by the looks it was being pulled out of my dad's pocket. Chad was next to him. It showed the tin vehicle and the bones were collapsed in a giant pile of rubble and sand and (now) bones. In the corner of the screen was still the vehicle, but I didn't see the little girls inside of it. My dad was saying something but I couldn't hear. And then Chad started screaming, my dad was freaking out. The camera was moving everywhere. They were both screaming and Chad collapsed and then my dad. And he fell with the camera, but he faced it his whole body. He's face was bloody and his legs were slaughtered, Chad was now just a pile of flesh gushing out and bones. My dad was muttering something, but between the fast moving lips and blood spewing out of his mouth it was hard to read his lips, and then he stopped moving all together....
I started a loud,"ohhhhhh my pop!" And then placed a hand over my mouth. With the strength my dad had left he put the camera in the best view so I can see everything. Sarah had an axe and was coming right for my cave. But she was sprinting to it, she wasn't going to cheesy-horror-movie-walk to me. I had seconds before she was here and was trying to cut my stomach with her axe. I grabbed her hands and the handle and she scream incredibly loud,"you were just going to leave us?!?"
"N-no! I was making a place to stay for us in this cave!" Still fighting the axe away from me, what were in her little skinny bones??
"LIAR!!!!!!"
Her screeching was terrible, it broke my heart that she was so upset. I ripped the axe from her little hands and I ran a few steps ahead until she grabbed my waist. I swung around and axed her in the stomach, but the axe was a little dull and it only made a cut.
She cried out but then laughed.
"I'm not trying to kill you Sarah! Only trying to hurt you so I can get away!"
I hit again with the axe and started for the jeep.
But... Where was her sister.....?
