"Gabriel!" he yelled at the top of his voice.
Few moments later, he appeared in front of him.
"Howdy, Cas!", Gabriel greeted, "what going on?"
Castiel looked at him. "I need your help" he said.
Gabriel frowned. "Really? What can I do for you?"
Castiel gulped before speaking. "Bring her back to life."
They looked at each other for a while, then Gabriel spoke. "Cas", he sighed, "I can't."
The angel clenched his fists. "Please, bring her back to life." he begged.
The archangel shook his head. "No Cas, it's impossible."
"I'm begging you brother, do it for me." Castiel said, a tear fell down his cheek.
Gabriel sighed deeply and shook his head. "Castiel, you know I can't do it, don't ask me that."
"Do you love me, Gabriel?" he asked suddenly.
The archangel stared at him puzzled. "Yes, Cas. You are my brother, how could I not love you?" he responded smiling at his younger brother.
"If it's true, then you have to do that. Please, give me Anna..." he begged with trembling voice.
Gabriel shrugged. "I'm sorry Cas, I really can't."
Castiel shook his head and looked at his brother angrily. " Why don't you want to help me, Gabriel? You can do it but you don't want. I never asked you anything, I knew where you were but I never said a word. Now I'm begging you and you turn your back on me!" he cried out.
"Cas! I can't defy Michael, do you understand?" Gabriel blurted out.
Castiel was silent, looked in his eyes and nodded. "I know", he said, "but I can't bear...." he moaned.
Gabriel walked to him. "Castiel, I'm sorry but I can't defy him. She wanted to kill his vessel's parents."
Castiel nodded slowly. "I know, but someone sent her . She.... she wasn't a betrayer..."
Gabriel smiled. "Cas... Anna has disobeyed."
"I know, Gabriel. I know", Castiel murmured, "but I need her... please, help me."
Gabriel didn't know what to say, he looked at his little brother and he felt powerless. "Please Castiel, don't ask me that, I can't." he repeated.
"You can!" the angel shouted.
"Yes brother, I could and believe me, I would like but I can't do it, I'm sorry."
"You don't understand my sorrow", Castiel said, "it's all my fault."
"What? Don't tell crap, pal!" Gabriel reproached him.
The anger flamed in his hazel eyes. Castiel was as innocent as a newborn. Nothing was his fault.
"Yes Gabriel, it's my fault! I could avoid all this!" he yelled.
The Archangel laughed. "How?" he asked.
"When Anna remembered who she was, I would have to protect her. I was blinded by my loyalty to the garrison, I feared to lose my wings. If only I had been braver, she would not die" Castiel explained to his older brother.
Gabriel stared at him frowning. "Are you serious, Cas? Would you have preferred to disobey in order to help a fallen angel?"
"I did it, and we didn't manage to stop the Apocalypse. If I had disobeyed then....."
"Enough", Gabriel snapped, "you can't be serious. You're upset now, I understand, but..."
"I loved Anna. I love her. I never told ...." he confessed trying to hold back his tears.
Gabriel sighed. "I know Cas, but she left you." he said gently.
The angel nodded. "Yes, and I think I will never forgive her for that. But I need her, so I beg you again, give me Anna. Raphael killed me and now I'm here, you can bring her back here. Please."
"Take my grace." Castiel said.
"Take my grace. Take it and give me Anna. Make us humans."
Gabriel chuckled. "You are crazy brother, if I take your grace, you die."
Castiel shook his head. "I don't know what to do, I can offer just my wings."
"I can't, I'll never forget Anna."
"I can't help you Castiel" Gabriel said.
"I see. I'm sorry to have bothered you. I apologize." Castiel said in a dry tone and turned.
Gabriel was really sorry for his younger brother, but he couldn't defy Michael. His older brother would punished him.
"Castiel!", he called, "please, wait."
Castiel stopped. "What."
"Look", began, "I want to be honest, I didn't like Anna, but believe me, I would like bring her back to life just for you. I can't, Michael could kill me..."
Castiel nodded briefly. "I understand... it doesn't matter"
The Archangel saw something strange in his eyes. "What have you got in mind?" he asked suspicious.
Castiel shrugged. "I don't know yet, but it's no business of yours." he responded harshly
His tone gave him the creeps. "Cas... Michael will kill you if you will try to..." Gabriel warned his brother, but he interrupted him.
"I don't give up, Gabriel. I will find out a way..." said Castiel with firmness.
"You are mad, Castiel. He isn't me, do you want die?" asked Gabriel.
The angel nodded and stared at him. "Yes, maybe I'm mad. I won't give up, I will find out the way to bring her back to life."
"I won't let you do it", Gabriel cried out, "you will die! I will stop you!"
"You'll have to kill me." Castiel replied and disappeared.
