"Now?" Sam thought that maybe he could sleep for at least an hour before they'd be back on the road.

"Yeah. Now," were the only words Dean offered his brother.

"But I haven't finished my beer?" Sam saw right through his brother, and knew that what Bobby said affected him more than he was letting show. Maybe if he could stall, Bobby would be able to get through to him.

"You went to college, Sammy. Chug it." Dean wasn't even making eye contact with his brother; he just kept walking towards the front door.

The more Dean tried to run, the more Sam wanted to keep him there. "Dean, I haven't slept in four days. Do you think we could just stay put for two hours?"

"Sleep on the drive there," he replied as he walked out of the house.

Dean sat in the car anxiously waiting for his brother to exit the house as well. When he finally saw his tall frame walking through the doorway, Dean noticed that his brother was not alone.

Sam offered the passenger seat to Castiel, "I'll take the backseat this time, Cas. I need to lay down."

It was obvious that the angel felt uncomfortable taking the seat next to Dean, but he didn't argue.

Sam was out cold after the first hour on the road. Dean had been expecting a barrage of questions from the angel, but instead all Castiel had to say was, "I'm sorry, Dean."

"You don't have to apologize for anything," Dean said quietly.

"No I do," Castiel replied in a tone that Dean recognized all too well. It was the tone the angel used whenever he thought he had let Dean down, "I should have protected you. None of this would have happened if-"

"No one said it was your job to protect me!" Dean gripped the steering wheel tightly, "Look we can have this conversation later. Okay?"

Castiel didn't answer. Dean felt terrible for treating the angel like this, but he didn't know what to do. Maybe one day he would be able to tell Castiel about what had happened, but right now the emotions were too raw to confront.

Sam woke up, the sun rose, and they crossed the Ohio state line, but the silence remand, until they reached Canton.

Dean pulled the Impala into the empty parking lot, "You guys just wait here. I'll be back in a minute."

He exited the car and walked down the same alley from 1944. He took a right, and found the same door. He knocked several times, and waited.

Five minutes passed before Dean decided to remove his lock picking kit from his jacket pocket. It was a tricky lock to pick, but Dean almost had it, before Castiel turned the corner and broke his concentration.

"What are you looking for Dean?" the angel asked as he walked closer.

Dean stood up, "In 1944, I met this organization called The Men of Letters. They told me that the Winchesters were suppose to be a part of it. Before they sent me back, They told me to look them up."

A sad look appeared on Castiel's face, "Dean, I'm sorry, but the Men of Letters are gone."

"What are you talking about, Cas?" the disappointment nearly destroyed Dean.

"They were all killed over forty years ago," Castiel walked closer to Dean.

The man just stood there. The only silver lining he saw was suddenly gone, and he didn't know what to do. Then, he noticed the angel walking closer. Castiel wrapped his arms around Dean, and wordlessly held him. Dean slowly brought his arms up, and grabbed Castiel tightly. He allowed himself to enjoy the embrace, but it didn't last long.

The angel started shaking, and his legs gave out. Dean managed to catch him, before he hit the ground, which is when he noticed the look of pain on the angel's face.

"Cas? Cas! What's wrong?" Dean tried to get Castiel to speak, but the only noise that came out of the angel's mouth were quiet winces. Dean quickly picked him up, and carried his body to the car.

Sam got out of the car when he saw the two, "What happened?"

"I don't know. He was fine a minute ago," Dean was unable to keep himself composed. Tears were beginning to stream down his face as he placed Castiel's body in the backseat, "Let's get him to a motel. You call Bobby to see if he has any idea what's going on."

Dean was in the driver's seat ready to go, before Sam could get out his phone.

"Hey Bobby, something just happened to Cas. Do you think you could find something about it?" There was a short pause, "I don't know. I didn't see what happened. Talk to Dean."

Dean reached out for the phone and began describing the situation, "One minute he was fine, and then he started shaking, and he just fell down."

Bobby's concerned voice responded, "Okay, I'll see what I can find out. Call me if anything changes."

"We will," Dean hung up and handed the phone back to Sam.

They pulled into the motel parking lot, and Sam walked to the office to get a room. Dean walked around the car to check on Castiel. He stopped shaking, now he just lay there lifelessly.

Sam came back to the car, and they walked to the room. Dean carried Castiel the entire way. Once they got to their room, Dean placed Castiel on one of the beds, and called Bobby back.

"Hey, Bobby. Cas is unconscious now, he still has a pulse, but we still don't know if that's just his vessel or what."

"Alright, Dean. I'm still looking for an answer. We don't have much on angels to begin with, so it might take a while, but I'll call you if I find any leads."

"Thanks, Bobby. For everything," he said before hanging up the phone.

Dean sat down in the chair next to Castiel's bed. As he stared at the angel's pale face, he didn't care about whether or not Castiel loved him. All that mattered was that he loved Castiel, and he wanted to be with him, even if it was only plutonic.

"Did Bobby find anything?" Sam's question barely phased Dean.

"Not yet," the older brother replied with his eyes still glued to Castiel.

Sam didn't really know what to do in this situation. Not even twenty-four hours ago, Dean wanted nothing to do with Castiel. That was the way his brother was though, and there was no sense in trying to understand it. So, he decided to change the subject, "So, you never told me what we were looking for."

Dean had almost forgotten, "It doesn't really matter anymore. It was a dead end."

Clearly Dean just didn't want to talk. Sam went on a food run, showered, called Bobby, but Dean remained silently in the chair next to Castiel. Finally, it was getting late and Sam was ready to get another couple hours of sleep.

"Wake me up if you hear anything from Bobby, okay?" Sam said as he settled into the hotel bed.

Dean simply nodded in reply. He hated feeling helpless, but that's exactly what he was at the moment. Maybe in the morning he could look for any information the Men of Letters left behind, and hope that they could help, but it was still a long shot.

Dean just sat next to the angel. Whenever Dean was in trouble, he'd just pray to Castiel. Now that Castiel was the one in trouble, Dean had no where else to turn. Eventually, the constant running through of different plans and situations began to exhaust Dean's mind, and he was slowly falling asleep.

Suddenly, the covers started to move, pulling Dean out of his drowsy state. He moved to sit on the bed, and placed both of his hands on each side of Castiel's face, "Cas?"

The angel slowly opened his eye, and when he saw Dean's face hovering over his, he couldn't help but smile. "Thought you didn't want to see me?" Castiel replied in a playful tone.

Dean looked away shamefully, and dropped his hands, "Are you okay?"

"I am now," Castiel replied quietly as he sat up and stretched his shoulders.

Dean stood up and nervously scratched the back of his head, "Can I get you anything?"

Castiel slowly rose from the bed, "I think I just need some air." Soon the door was closing, and Dean was left standing in the motel room.

Five minutes passed before Dean decided to go check on the angel. He exited the room to find Castiel with his back turned, sitting on the curb.

Dean slowly walked over, and leaned against the impala, "Listen, I'm sorry, and I know I owe you an explanation but-"

"It's okay Dean, I understand."

"No, Cas, you don't," Dean took a step towards the angel.

Castiel stood up, and walked closer to Dean, "No, I do." Suddenly, Castiel's hands were holding Dean's face, and the angel was gently pressing his lips against Dean's.

He was in shock, but only for a moment. Dean wrapped his arms around the angel's waist, pulling him closer. He sucked Castiel's lip, hoping to get a moan out of his angel, but he was the one moaning.

Castiel pushed Dean against the impala, and rolled his hips into the man. Dean's need increased, and he let it show in his kiss. Castiel only managed to pull away from Dean for enough time to say three words.

"I remember everything."
