Chapter 1
As Dean and Sam fought Crowley's men, Cas made his way slowly to Samandriel. When he reached his brother, Cas began to unscrew the screws from his head, loosening the headgear as well. When Cas removed the screw that was first inserted, Samandriel relaxed and Cas got flashbacks of Naomi torturing him in a white room. "Hold still!" she ordered and Cas screamed as she drilled into his head. Cas then snapped out of it and continued to remove the torture device from his brother. When the last spike was removed, Cas lifted the headgear off and Samandriel looked up at him in relief as Cas put his hand on the side of his brother's blood-stained face. Before Dean could stab the doctor, the man cried out. "I know things!" he exclaimed. "Cas! Go!" said Dean and Cas left with Samandriel with the sound wings heard.
When both angels reappeared outside, Samandriel was shocked. "Everything's okay. You're safe. We're going home." said Cas. "No! Don't take me back there, Castiel!" stated Samandriel. "What do you mean?" asked Cas. "I told Crowley things that he had no right to know! He got to our coding…secrets I didn't even know we had!" cried Samandriel. "What secrets?" asked Cas. "Heaven? Naomi?" asked Samandriel. "Who's Naomi?" asked Cas. "Who's Naomi? Listen…I have been there! I know! They're controlling us, Castiel!" cried Samandriel. "What are you talking about?" asked Cas, who then found himself in Naomi's office. "KILL HIM!" she shouted when she got in his face. "What does he mean they're controlling us?" demanded Cas. "Castiel!" she exclaimed. "Who is controlling us? Why did I see your face? Why was I so afraid? What did you do to me?" asked Cas. Enraged, Naomi grabbed Cas by his coat and lifted him out of the chair. "This is a direct order! Kill him!" ordered Naomi and pushed Cas away. When Cas came back, he summoned an angel blade and stabbed Samandriel, and the familiar light shone as he died. Cas sank down as his brother's body did the same and pulled out the angel blade.
"What did I just do?" Cas asked Naomi. "You killed a traitor. You did Heaven a great service." said Naomi. "That's what I tell Sam and Dean?" asked Cas.
Cas was sitting and holding Samandriel, his forehead resting on his brother's head when Sam and Dean came running out of the warehouse. "Cas!" called Dean as they came up to the angel. "What the hell happened?" asked Sam. "Tell the Winchesters that Samandriel had been compromised." said Naomi. Cas looked up, face wrought with sadness. "He was compromised." said Cas. "He came at you and and you acted in self-defense." said Naomi. "He came at me…I killed him in self-defense." repeated Cas. "Say you must return his body to Heaven and bring him to me." said Naomi. "Cas, you okay?" asked Dean when the brothers saw that blood was coming from Cas's left eye and he wiped it away. "My vessel was damaged during the attack. I have to go. Samandriel's remains belong in Heaven." said Cas and bent down and put his arm around Samandriel's shoulder. "Cas, wait!" exclaimed Dean. "Thank you, both…for everything you've done." said Cas and hung his head. "Cas!" stated Dean and the angels were gone. Dean walked to the spot where the angles had just been and looked around, lost.
