Chapter 1
"Please" Castiel cried
He looked up from their corpses. The corpses of the two boys that had showed him happiness, taught him love, and gave him family.
"Please!" Cas sobbed, his voice breaking while he looked down at their motionless forms. On his knees, tears flowing down his cheeks and splashing into the growing pools of still-warm blood. His father placed a hand on his shuddering shoulder.
"Lucifer is caged, Castiel. The cost was great but why cry over these mortals?" God, Chuck, said. Cas just looked up at him with eyes filled with grief and despair.
"Please," Cas wept, his so voice so raw and full of pain, so against how God programmed his angels, he decided to do something he had never done before. In his eons of existence, he had never made a mortal immortal. And that is what he did now, as he crouched down and laid a steady hand on either boys' foreheads. He called their souls from heaven and transformed them into angelic grace. Cas let out another heart wrenching sob as their bodies were surrounded by glorious white light. When it faded, Sam and Dean were on the ground, newly formed wings spread beneath them. Dean's, a charcoal grey and Sam's, white that were speckled throughout with grey. Cas felt Chuck's hand on his shoulder.
"Be happy, Castiel," he breathed and vanished.
Cas sat in a silent vigil, waiting for his family to awaken. As the sun creates the horizon, Dean let out a sputtering cough and opened his beautiful green eyes. Cas let out a small sound as he watched Dean sit up, Sam still passed out beside him. He glanced around, then stood up unsteadily. Then, noticed his magnificent wings. His eyes widened and he noticed Cas staring at him, tears threatening to spill over once more.
"What happened," Dean groaned.
"You died," Cas whispered, "You and Sammy, you died," and his voice broke. Tears flowing down his cheeks once more. He felt strong arms pull him up and into an iron-wrought hug. Cas clung to Dean, breathing him in, iron and leather. He held on until his tears dried. Dean pulled back enough to see Cas's red-rimmed eyes.
"I'm back and I promise I won't leave again," he murmured and after a second's hesitation, pulled Cas into a deep kiss. It was breathless and wild and lasted for five thunderous heartbeats. Cas pulled back and stared into Dean's gorgeous eyes, then at his slightly swollen, pink lips and kissed him again.
Sam moaned and they quickly pulled apart just before Sam rolled over and sat up, then noticed his wings and promptly fainted. Cas scratched the back of his head as he watched Dean walk to his brother's side, hands in his pockets.
