Notes: See part one

Dean couldn't contain a startled yelp that escaped from his lips as the fire raced toward him. He struggled to slow himself, to catch himself on something, anything.
But there was nothing.

With a delighted laugh the Crossroad demon snapped her fingers and the flames vanished.

Dean crashed hard onto a cement floor.

Dean muffled a curse as he struggled to sit up. With no time to brace himself his left shoulder had taken the brunt of the impact.
It felt like it was on fire and Dean felt blood trickle down and hit the sleeve of his shirt.

"Had fun with that, did you?"Dean asked as he slowly got to his feet.

The woman smiled. "Yes, actually. You deserved that one."

"So I'm just supposed to trust you."

"Yes and we all get what we want. Sam gets happily ever after, and I get eternity to play with you."

"Bring it on."Dean stated with a grim smile. At least in a fight he'd have a chance of controlling the situation.

The Crossroads demon waved her hand.

Dean waited.

Sharp pain shooting up his arm forced Sam's dazed mind to focus. He glanced down to find the source of the pain and found a nurse wrapping gauze tightly around his right hand, wrist and forearm.

The young red haired woman smiled at him kindly. "We removed all the glass, and closed the wounds. I've given you a light pain medication. If the pain gets worse let us know and we'll increase the dosage."

Sam nodded as he absently covered his right arm with his left hand. "Thank you."

"Sam….."Weir began after the nurse left.

Sam turned to face Elizabeth. As he did Sam realized they were still in the main area of the infirmary. Just the opposite side from where Sam had hit the wall.

"How's Dean?"Sam asked anxiously as he looked away from Weir and Sheppard to the smaller room where his brother lay.

"Beckett's still working on him."Weir replied gently as she moved toward him. She placed a hand on Sam's good arm to gain his attention. "Sam, what happened?"

Sam shook his head. "I don't know. Dean was sleeping when I left earlier. So when I returned and found him lying there I assumed he was still asleep. I tried to wake him, he didn't respond. That's when I noticed he wasn't breathing."

"No sign of a struggle?"Sheppard inquired from his spot by the wall.

Sam shook his head. "No."

"I'm afraid my findings won't shed any light on the subject."Beckett stated as he appeared from behind the trio.

Sam was instantly on his feet moving to stand in front of the doctor. "How's my brother?"

Beckett sighed inwardly. There was never an easy way to handle this part of the job."I'm sorry,lad. Dean's slipped into a coma."

Sam felt his knees buckle and he reached behind him for the small square chair he'd been seated on earlier.

John saw Sam's reach fail and he quickly moved to grasp Sam by the shoulders and ease him over to the chair.

"How?"Sam whispered. "He was fine this morning."

Carson knelt down in front of the younger man. "Sam, I've run every test I can think of and there's no medical reason for this to be happen'. Even his neuro scans come back negative."

"Tox results?"Elizabeth asked quietly even though she knew Carson had already run the test.

Beckett glanced up and nodded. "Aye, negative as well. No poison in his system."

"Thank you, Carson."Weir acknowledged. "Keep me posted of any change."

"I will."Beckett replied with a nod as he left.

Shakily Sam turned to face Sheppard and Weir.

Sheppard stayed close by Sam ready to give support if Sam's unsteady body failed him again.

Sam motioned them to a quiet corner. "The only thing I can think of is that the demon Dean made the deal with revoked it."

"Sam…."Weir began but Sam waved her silent.

"I know this is still new to you and you don't quite believe me, but hear me out."Sam pleaded. "It's the only thing that makes sense."Sam's voice dropped to a tortured whisper."I've just never heard of a demon taking a soul this way."

Sheppard knew he shouldn't ask, but the words came out anyway. "How do they usually…..take it?"

"Hell hounds."Sam replied quietly as he turned back to look at his brother's still form.

"Of course."

"If you'll excuse me."Sam said as he began to move toward the door. "I need to sit with my brother."

"We're here if you need us."Sheppard stated.

Weir sighed. "I'm going to update SGC and talk with Dr. Jackson see if he has any ideas."

"What's going on?"Ronon asked as he made his way out of Teyla's infirmary room.

"Sam found his brother unconscious and not breathing."Elizabeth replied quietly.

"He's in a coma and Beckett doesn't know why."Sheppard added. "How's Teyla?"

"Same."

"John,"Elizabeth stated as she moved toward the door. "I'll be back in an hour. As you keep an eye on our guests can you radio Rodney and see what he's found?"

"No problem."
