Left for Dead Continued

While we were walking through the sand, G whispered, "Sam?"
"Yea?"
"I have something to tell you," He stopped.
"M'Kay, but um why are you whispering?" G grabbed my hand and pulled me into the woods.
"Hey!" I protested as G put a hand over my mouth.
"Do you ever shut up? I need to tell you th-" A shot could be heard in the distance. Terrified, I clung to him.
"It came from the barn," I remembered something," Oh no! Josh!" G's eyes widened and we ran towards the barn.
**********************************************************************************
"Josh! Josh!" I screamed, "Josh!"
"Sam, don't worry, he's fine," he sighed, "I hope..."
"GRIFFIN! He's my brother! The only family I have left! You expect me not to worry!? What if he was shot? Ohmygosh" I put my head in my hands," He's dead, he's dead,"
We walked into the barn, "Josh?" I whimpered.
"Yea?" Came the muffled reply.
"J-josh?" I saw him come out from behind a bale of hay, "JOSH!!!"
He saw me and smiled," I think we've established that my name is Josh...." He caught me in a hug, "I'm fine, Sam."
