We know who the next victim is, so we're flying down the street in the Impala to get to the warehouse where the next victim works. It's late at night, but he's a nightguard. Dean and I get to the warehouse and stop. We run inside, guns raised. Sam is trying to burn the bones.
We hear gunshots and shouting above us so we run up the steps. We see Alex cornered, and Jason has his gun aimed.
"Hey!" I shout. Jason looks at me and I shoot him with the shotgun, bullets full of rock salt. He disappears. Dean and I run over to Alex.
"Are you hurt?" Dean asks.
"N-No." Alex replies.
"Come on." I say. "Let's get you out of here."
"Behind you!" he shouts, and I duck when I hear a gunshot and a bullet bounces off the rack next to me. Dean is suddenly in front of me and he shoots at Jason. Jason disappears.
"Get him out of here." Dean says.
"Dean, no, I'm not-"
"Go!" he says. I sigh and rush Alex out of the room.
"Who was that?" he asks.
"Which one?" I say.
"That Dean guy." he says.
"He's my brother." I reply.
"Are you close?" Alex asks, and we get outside.
"He's one of the greatest people I know." I reply. There's a gunshot inside and I hear Dean shout. "And I'm gonna save his ass!" I call as I run back inside.
DEAN'S POV
I try to wrestle the gun out of Jason's hands. I notice Rachel by the door, aiming her shotgun.
"Shoot!" I shout.
"I can't!" she says. Jason throws me into a wall, and steps in front of me, and I try to get the gun again.
"Shoot, dammit!" I shout.
"Dean, I could hit you!" she says. A bullet gets shot from Jason's gun and I try to grab it. Suddenly I jump back as he goes up in flames. I look at Rachel.
"Why didn't you-" I stop. She takes her hand off her side and it's covered in blood. She starts to collapse but I rush forward and catch her just in time. I sit down with her head on my knee, and try to keep pressure on the wound.
"Dammit."
"Dean." she breathes out.
"Yeah, I'm right here, kiddo. I'm here." I say. Sam rushes in the room, and sees the scene before him, and runs over and sits next to me.
"Oh god." he says. Rachel smiles weakly.
"Sammy." she breathes. "I'm sorry."
"Stop it, you're gonna be fine." I say. She coughs and blood drips from her mouth. I exchange a worried look with Sam.
"No deals." she breathes.
"We aren't gonna need to make deals, Rach, you'll be-" Sam says, but she cuts him off.
"Promise… me." she says weakly.
"I promise." he says, his voice cracking slightly.
"I promise." I say. She lets out a shaky breath.
"I love you guys." Rachel says.
"We love you too, kiddo." Sam says. She smiles slightly.
"The Winchesters that changed my life. That saved me." she says. "Th-Thank you." Then her head rolls to the side, and her eyes look glassy. She stops breathing.
Sam and I stare at the body on the floor. How could we have let this happen? How could I?
"Hello." someone says behind us, and we see Cas.
"Cas." Sam says.
"Ready?" he asks.
"For what?" I ask.
"To reverse the spell." he replies, making my heart break more. I sigh.
"It's too late, Cas." I say. He looks horrified.
"What?" he asks. I step aside, and let him see Rachel. He stares at her. He walks towards her, and kneels down. After a few moments, he winks out.
