Castiel made his way into the church and snuck down the steps to the sounds of Amber's screams. His heart pounded in terror. He peeked around the corner and saw a demon standing guard in front of a metal door. The knife and Dean and Sam's guns stuck out of the top of his pants. He made eye contact with Dean who peered out of the small window in the door. They nodded at each other in silent agreement. Dean started to yell and heckle the demon to get his attention. The demon turned around and focused his attention on Dean, while Castiel found a wooden chair at the bottom of the steps, picked it up and slammed it up against the demon's head knocking him unconscious. Castiel kicked the body out of the way of the door and freed Sam and Dean from the room.
"C'mon! They started the ceremony!" Castiel yelled grabbing the knife and guns and handing them to Sam and Dean.
"Hang on..." Sam said taking the knife and cutting the demon's arm exposing a steady stream of blood. Sam consumed as much blood as he could and dropped the arm meeting up with Castiel and Dean outside the door where Amber was being held. They heard ominous chanting on the inside and Amber screaming out for help.
"Here you take the knife." Sam ordered Castiel as his eyes began to turn black. "Take out as many demons as you can, I'll hold Lucifer."
Dean kicked open the door and found Lucifer holding the blade high above his head about to make the sacrifice.
Castiel seeing the blade quickly ran over to Lucifer and plunged the knife into his back....making him drop the blade and stunning him temporarily.
Sam raised his hand and held Lucifer in place while Castiel removed the knife. Dean began shooting the minion demons as they moved toward him in retaliation.
"Cut her loose, get her outta here!" Sam yelled struggling to keep his demon blood hold on Lucifer.
Castiel ran over to the table and cut the straps holding Amber down. He sat her up on the side of the table.
"Cas! Watch out! she yelled as a demon attempted to grab Castiel. He spun around quickly and slit its throat knocking it to the ground.
Sam continued his hold on Lucifer and once Castiel had cut Amber from the table, he turned his power into overdrive, lifting Lucifer up off the ground. Lucifer's eyes turned white and his skin glowed as it melted. He dropped his head and laughed.
"This isn't over Sammy! You can't kill me!" Lucifer chuckled as he watched his skin melt off his vessel's bones. "I'll be back for her!"
Suddenly Lucifer exploded into a bright light leaving nothing left of his former vessel. The explosion was so massive it shook the room and knocked the four back into the corridor. The church itself began to rumble and crumble around them. Pieces of the ceiling and walls began to crack and fall.
"It's gonna collapse!" Sam yelled as followed in behind Dean, Castiel and Amber who ran frantically up the steps and out of the church and down the sidewalk before a final loud explosion signaled the total destruction of the entire building.
The four watched as a large cloud of dust bellowed from the ruins.
