(Disclaimer thing: I OWN JACK SQUAT!)
Castiel groaned as his head pounded. The last thing he could recall was Raphael blowing him to oblivion...yet, he could see something over him...
"About time you got up, you idiotic git." The voice came from a man with dark hair in a brown coat with matching pants and a hooded shirt under it. A superior who'd been AWOL.
"Metatron?" Castiel clambered to his feet before attempting to bow. It was then he noticed the woman next to him, with brown hair and an odd silver outfit. "Who...how..."
"She can rebuild you. She has the technology. She can make you better, stronger, faster." Metatron replied as she did a handstand. "However given her quirky sense of humor, you may have a tail additionally."
"But how...." Castiel glanced down and frowned. That white puffy tail wasn't there before...
"Be happy you're not a platypus. I believe the answers you seek lay in my companion's eyes." Metatron replied simply as she pulled her eyelid down. Castiel held his head.
"I'm confused."
"You were just a molar in the Prophet Chuck's hair-and by the way, he and Luke were nothing compared to Jay and Silent Bob. Ow!" He turned to where the woman had smacked him. "Right. My companion asks me to remind you to fulfill your purpose. The Winchesters are in danger. Zachariah has given Dean stomach cancer and removed Sam's lungs. Assist them at once!"
"Right, Sir!" It only occurred to him after he vanished he had no idea who 'she' was.
