Thanks for the reviews! Like I pormised I'm updating my stories today :)

Castiel had left as quickly as he had arrived. Dean scooped Sam up and carried him to the bed. He cursed himself at every step he took. He had just gotten done telling Sammy he wasn't going t o leave him, and then he did.

"I'm so sorry, Sammy," he whispered, teary eyed. "So sorry." He brushed his brother's hair back gently and covered Sam with a blanket.

"Dean," Bobby sighed. "I know what you're thinking, and-"

"Don't tell me it's not my fault, Bobby," Dean snapped. "I promised I wouldn't leave him and I did for a split second and…" He shook his head "I swear to God, I'm never leaving his sight again," he muttered. And Bobby could tell that at that moment, Dean was being dead serious.

He sighed and nodded to Tom.

"We'll leave you alone. Let us know if you need anything, and if he wakes up."

Dean nodded, not taking his eyes off of Sam's face.

A few hours later Sam's eyes fluttered open and he glanced around the room in a dazed manner.

"Hey, Sammy." Dean's voice was soft when he spoke. He didn't want to frighten the kid.

Sam glanced at him.

"Dea?" He was struggling to speak, Dean could tell. "Wha…appened?" With the situation Dean wasn't surprised that the way Sammy talks had been affected.

"Demons tried to poison you," Dean told him. "Castiel saved you."

"Cas… demo…"Sam's voice trailed off. It became so hard for him to try and form complete sentences. Dean hated to see him struggle like this. "I don…understa.." Sam added desperately and Dean remembered that Sam's comprehension level had been affected too. Didn't Castiel tell him he would have the mind of a young confused child? How young? Sam was around 10 or so when he found out that monsters were real. Dean realized this was probably before then. He sighed in frustration.

"Nothing, Sammy, don't worry about it." He grasped his brother's hand. "The important thing is that you're okay. That you're alive."

Sam studied the room.

"Whe…whe…" He tried to say but Dean understood the question.

"Where are you?" He asked and Sam nodded weakly.

"At a friend's of Uncle Bobby's. You remember Uncle Bobby, right?"

Sam nodded again.

"Bo…bby,"

"Yeah, he's here, you wanna see him?"

Sam nodded, more eagerness in his face now. Dean called for Bobby to come.

"Hey kiddo," Bobby said gently, remembering what Castiel had told them.

Sam gave a smile in response.

"Uncle Bobby," he said softly, relief in his voice.

"Yup, and just like your big brother I ain't leaving any time soon. You need anything you just holler, okay?"

Sam nodded . Bobby eyed Dean.

"You need anything?"

Dean shook his head.

"No thanks." Bobby nodded.

"When you need some rest, just let me know okay? I'll take over."

"Thanks, but I'm not going to be resting for a while," Dean said grimly. He wasn't going to take his eyes off of his brother ever again. Bobby frowned at that, but choose to remaine silent. Slowly he left.

"De...Dea?"

"Yeah, Sammy?"

"Where's...Where's..."

"Where's who?"

"Da...d..."

Dean's face stiffened at that. How the hell was he going to explain this to Sammy?"

"Out, away for work. You know how he leaves for weeks at a time."

Sam nodded.

"W...when he coming...bac...k?" Talking was becoming more and more difficult for him.

"I don't know, Sam." Tears stung Dean's eyes. He hated lying to Sam but he knew Sam was in no shape to hear that their father was dead. And had been dead for a while. "But I'm going to take care of you, okay?"

Sam slowly nodded and shuddered. Dean sat up.

"What's wrong?" His voice was sharp.

"Col.."Sam's voice trailed off slowly. Exhaustion was creeping inside of him.

"Cold?" Dean finished and Sam nodded. Dean got up to grab a blanket on a nearby chair.

"Dea!" Sam started to sit up the best he could, fear in his eyes. "Don!"

Dean turned around sharply.

"Don't what?"

"Lee..lea.." Sam murmured.

"Leave?"

Sam nodded.

"Sc...scared of...alone..."

Pain filled Dean to hear his brother speak like this. He swallowed.

"I'm not leaving you Sammy," he said slowly. "I'm not leaving you ever again. I'm just getting a blanket." Slowly Sam's shuddering stopped as he nodded, his tense limbs relaxing as Dean covered him with a blanket. And Dean started to rock him back and forth while running his hands through Sam's hair.

"I'm never leaving you again," he added softly, determination in his voice. Sam closed his eyes, feeling safe in his brother's arms, and fill into an exhausted sleep.

Sorry for it being so short, but it's better than nothing!
