Dean led The Doctor and Sherlock to the sitting room. Castiel's blood soaked the carpet. John sat next to Sam who tried to fix his wounds. John was gripping Cas' right wrist for some reason.

"How's he doing, doctor Watson?" The Doctor asked.

"I don't know, really. He's possessing the body which means the body isn't really working anymore. When you possess a body, the body stops and you control it. What's the point of putting in effort to beating a heart when all you need is the legs and the arms and the senses? And if anything does get broken, you could just patch it up together. No big deal. So it's not the body that's injured- it's his soul. Meaning, they used an angel blade to harm him."

"Is he dying?" Dean interrupted. Tears brimmed his eyes. But he will come back, right? He always comes back.

John slightly loosened his grip on Cas' wrist. Blood sputtered out and a bright light shown from where the blood is coming from.

"His spirit is leaking out. The body is not repairing itself. Only he can save himself but he lost too much spirit- too much power- to do anything."

"So we just sit here and let him die?!" Dean cried.

"Do you have a better idea?"

"How about let him live. Maybe after some time he could bring more soul back and then repair the wounds." Sam said.

"Or we could let another driver take place." Sherlock said.

They all turned to him "What?" John asked.

"Think about it. If we let the soul of the guy he's possessing- the natural soul or the one that's been with the body since birth- take over, he could get the body going again and the body could heal the wounds again. Just like before Cas possessed him. And with the organs not being used for a long time, it could easily repair the body in a few hours."

"So let me get this straight, Charlotte." Dean said, holdin up his hand "We let old Jimmy take over and he will jump start the body and repair the wounds faster?"

Sherlock nodded and said "Don't call me Charlotte."

"If you want to change your clothes then turn to the right and look for the first door you see to your left side." The Doctor told him.

"Why would I want to change my clothes?" Sherlock slowly asked.

The Doctor shrugged "Maybe you would want to wear… girl garments?"

Sherlock pursed his/her (confused but going for her) lips and said "John, come along." She grabbed John's arm and left the room.

The Doctor rubbed his hands together and pulled up his sleeve. He closed his eyes and placed his hands on both sides of Cas' forehead.

"Can you do it, doc?" Dean asked.

"I can get into his head so maybe I can shift him from Castiel to…." He opened his eyes. The wounds suddenly closed and Castiel opened his eyes.

He didn't do anything. He just looked at the three men hovering above him. He took a deep breathe and said "I…" His eyes widened. "I can talk again." He blinked a couple of times. "I'm in control!" He was about to stand up when he fell on his back "I'm in pain!"

"Jimmy?" Sam asked.

"Yes?" Jimmy asked, looking at him.

"It's really you then?" Sam smiled.

"Yes." Jimmy chuckled. "It's been a while."

"Jimmy, you know this won't last, right?" The Doctor said, looking at him. He didn't show much movement to indicate his expressions but his eyes gave away everything just like how it gave away his true age. He was sorry. The Doctor wanted nothing more than to let this man go. To let Jimmy live with his family but that was not an option.

Jimmy's smile slightly disappeared "No. I know. I was awake the whole time. When Castiel is ready, I'll let him take over."

The Doctor smiled sadly. "Thank you, Jimmy Novak."

"My pleasure" Jimmy clapped his hands together "So. A secret order, Sherlock a girl, multiple internal bleedings in my back. Where do we begin?"
