Soon, Sam lost track of how much time had passed. He had long ago given up on trying to read the clock; his vision had become blurry from being over tired. Finally seeing Dean in a state of restful peace calmed his nerves and made him realize just how sleep-deprived he was.
A few minutes wouldn't hurt. Sam glanced at Dean's heart monitor, happy to see that he was still alive. He smiled down at his brother, slightly disappointed when he, unsurprisingly, did not smile back.
Sam's head lolled back so he was staring at the Christmas snow white ceiling.
"You're not going anywhere, Dean," he murmured, before falling into a restless sleep.
Sam woke up with a start. At first, he was not sure where he was, but after looking around for a bit, everything came flooding back. He pressed the heels of his hands into his eyes, trying to make the memories go away, but no matter what, they clung to the back of his mind. A noise coming from the window shocked him out of his regret.
The pane was rattling open, seemingly by itself. Sam leapt up from his chair and slowly walked over, afraid of what might be outside; what he saw shocked him. Climbing into the room was a person that neither Sam or Dean had seen in three years: it was Cas.
Sam wanted to be relieved that the angel had finally shown up, but he was more angry than anything.
"What the hell do you think you're doing?!" he shouted, not caring who heard. "You disappear for three years and you think it's okay to just show up? Where have you been?!" Tears were streaming down Sam's face, but Cas just walked right past him. Angered even further by this, Sam attempted to grab Cas' shoulder and turn him around, but his hand just went right through the angel's shoulder.
"What...?" he sputtered, looking at his hand to make sure it was okay. Sam was taken aback and fell silent, choosing to watch Cas slowly walk over to Dean.
Then, the strangest thing happened. Cas gently shook Dean and he awoke. He sat up in his hospital bed, a soft smile on his face, and his green eyes turned to look up at Cas.
"I've been waiting for you," Dean said happily, taking the angel's hand.
"I'm sorry it took so long," Cas whispered, tears forming in his eyes. "You ready to go?" Dean nodded and climbed out of the bed, sighing as his feet hit the cold hospital floor. The pair walked over to the window, hand in hand, and began climbing out. Dean turned around one more time, smiled, and waved to his brother.
"Wait... No, no, no," Sam said, frantically. "Where are you taking him? Where are you going with Dean?! Cas, get back here! Don't take my big brother from me!" He ran to the window, hoping to grab Dean, but it was too late; they were already flying off towards the stars.
Sam awoke once more, this time to the sound of a loud, steady beep; Dean's heart monitor had flat lined.
"Doctor! Nurse! Someone get in here!" he screamed, holding Dean in his arms. Tears poured down his cheeks, dampening Dean's hospital gown.
Doctors and nurses came rushing in and began prying Sam from his brother.
"No! I have to stay with him! He's my brother!" Sam cried, trying to break from the nurses' grip. He looked at the doctors, hoping to see some sort of effort to save his brother, but the doctors were just shaking their heads.
The last thing Sam saw before he nurses dragged him out of the room was the doctors pulling a sheet over Dean's face.
AN:
It's not done. There's still another chapter to come. Maybe Dean's not dead...?
