Summary: Tag to 5.01 Sympathy For The Devil. Sam leaves thinking Dean and Bobby don't want him around, but ends up in the middle of a very dangerous turf war between two different species of supernatural monsters.

Chapter 1

Sam watched Dean as he walked to the Impala, he felt like he was unable to move, Dean's words were whirling around his head. "You trusted a demon over your brother and looked what happened. I just don't think we can be what we were, you know? I just don't think I can trust you." The last sentence hit him like a ton of bricks. Those words were soon joined by Bobby's voice. "You were reckless, and selfish and arrogant!" "I'm sorry" "Oh yeah, you're sorry you started Armageddon. This kinda think don't get forgiven boy! If by some miracle we pull this off, I want you to lose my number, you understand me?" Bobby had told him that it was the demon talking, but Sam couldn't forget those words in Bobby's voice, the person he's considered as a second father since his mom died, the person who raised him along with his brother.

He guilt and self-hatred building up inside him was unbearable. He stared at Dean when he gave him another glance from the driver's door. His big brother's eyes was full of pain and angst. Sam's eyes were burning with unshed tears, he had caused Dean all that pain.

"Umm.. I think I'm going to go for a walk, I'll meet you back at the hotel room." He finally croaked out, he knew he had to leave, Dean didn't need him, neither did Bobby or Cas. He turned away from Dean as the tears began to fall. He took a weary step forward, uncertain if his legs would buckle, thankfully they didn't. He started shuffling away from Dean, hopeful Dean would tell him not to go, tell him to get in the car and stop being a bitch. He reached the corner of the hospital building, looking back to see Dean getting in the car. Turning away again more tears fell. It was quicker to get back to the motel on foot, cutting through the park instead of having to drive all the way around. He decided he'd go back, grab his stuff and leave before Dean arrived back.

Dean walked towards the car, knowing the words that just came out of his mouth had hurt his brother. He arrived at the driver's door and sighed, he turned back around to Sam. Sam looked paralyzed, stuck the floor beneath him, his eyes glistened with tears.

"Umm.. I think I'm going to go for a walk, I'll meet you back at the hotel room." Sam mumbled, his voice quiet, broken. Before Dean could reply Sam turned away, Dean knew he was crying by the way he stood, the way his shoulders sagged.

Dean sucked in a breath as Sam took a hesitant step forward, paused, and then started to walk. Dean wanted to stop him, to take them words back. "As if he doesn't feel bad enough, well done Dean!" Dean cursed himself. He decided to give him some time, he yanked the door open and ducked down into the seat. He looked at Sam through the window, catching him looking back towards him, even though it was dark, he could see the tears falling down his face, his eyes looked dull and defeated.

Sam disappeared around the corner, "I need a drink" he thought turning the car on set on finding the nearest bar.

Sam trudged through the motel car park, thankful for not seeing the black Impala parked outside their room. He stumbled through their room's door, searching frantically for his bag, finding it on the chair in the far corner. He almost ran across the room, picking up the bag and throwing it on his bed, he went to the drawer pulling out most of his clothes, also dumping them on the bed. He grabbed the rest of his stuff from the bathroom. He shoved everything quickly into his bag, determined not to be here when Dean got back, he couldn't face him again, couldn't face the disappointed look on his face.

Zipping up his bag and hefting it up onto his shoulder he crossed over to the table, grabbing the little notebook on the shelf above the tv. He stared at the blank piece of paper for a moment, not sure whether it was worth leaving a note, would Dean care anyway if he was gone? He decided to just incase Dean still cared a little bit about him. He scribbled down what he wanted to say, putting down the pen, he sighed not knowing where he could go. Looking around the room one last time "I'm sorry Dean" he whispered to the empty room. He shuffled towards the door laying a hesitant hand on the handle, he looked down trying to blink away the tear that were threatening to leak from his eyes again. He turned the handle and exited the room.

2 hours later...

Dean stumbled drunkenly up to his and Sam's motel room, he tried to open the door. "Keys!" He muttered to himself, he dug through his pocket, his fingers finally meet cold metal, "there you are" he muttered again, pulling out the key, shoving it into the keyhole. A minute later he finally managed to get the door open.

He expected to see a gigantic lump, Sam, in the furthest bed "huh.. Must be a long walk." He grumbled to himself then he found it empty. He slumped down on his bed exhausted. He pulled his shoes off and lay down on the bed. Two minutes later, the room was only full of the soft drunk snores of the older brother.

Sam managed to "borrow" a car. He made it two towns over before finding himself to tired to keep his eyes open, he decided to find a motel and get some sleep.

10 hours later...

Dean woke up with a banging headache, he sat up slowly bringing a hand up to his head when a sharp pain shot through his skull "aahh.. gaahh... hangovers suck!" He yelled, expecting to hear a chuckle from Sam. He turned to look over to Sam's bed, it looked like it hadn't been touched. "Sam?" He turned to the bathroom, the door was open, meaning Sam wasn't in there. "Must've went to see Bobby" he thought instantly, flinging his legs over the side of the bed. His belly grumbled and moaned "wow! I'm starving!" He said, finally finding his feet and standing up.

He went to go have a shower and get dressed before leaving the room to go find a diner, he hadn't noticed Sam's bag missing or the note left on the table.

After breakfast he went to the hospital to see Bobby and hopefully find Sam.

Entering Bobby's room he saw Bobby looking out the window. "Hey Bobby! How you feeling" He said happily. Bobby turned and looked up at the young hunter.

"How do think I am, I'm in a friggin' wheelchair!" Bobby scowled.

"Alright, sorry!" Dean replied "how's Sam this morning?" He questioned.

"What do 'ya mean? I haven't seen him." Bobby said confused.

"You haven't?"

"No why, when's the last time you saw him?" Bobby's eyes filled with concern.

"Um... Last night, he said he was going for a walk, then when I woke up this morning he wasn't there, I assumed he had come here." His own eyes were now filling with concern and fear.

"And you saw him last night, he came back to your room?"

"No... I went out for a drink after I said... Umm.. he wasn't there either." Dean explained.

"After you said what?" Bobby asked suspiciously.

"I said.. I.. That I didn't trust him, that we could never be what we were." Dean lowered his head, unable to look at the shocked look in Bobby's eyes.

"Aw.. Hell, kick him when he's down why don't 'ya. What about his stuff, was that there?" Bobby was really concerned now.

"I don't know" Dean's voice went quiet, "I didn't check, I just thought he was here."

"Well go back and do it now!" Bobby yelled harshly, he regretted as soon as he saw the worry and fear in Dean's eyes.

Dean turned and walked out the room without a word.

What will happen next? Will Dean try to find Sam?
