"Alright, talk to you later…yeah, bye" Bobby set the phone back in its cradle and sighed. He walked over to the fridge, pulled out a beer, and carried it over to the table. Dropping into a chair he popped the top of the bottle and took a big swig thinking over his recent phone conversation. Thinking about the call just made him angrier and angrier until he finally snapped. Slamming the beer bottle down on the wooden table Bobby yelled, "That's it! I've had enough of this shit!" He began pacing the length of the room muttering to himself as he attempted to work out a solution to the problem at hand. After a few minutes of pacing, he stopped and looked up at the ceiling. There might not be any way for him to fix things, but he knew who could. He just had to remember the name. "Let's see Cas-andra? No, that's not it, Cas-elberry? Nope, definitely not. Ummm, Cas-cade? No way." He thought making a face. "Come on, come on, I know Dean told me his name, it was Cas, Cas, Castiel! That's it! Castiel!"
With the angel's name remembered and a plan formed there was only one thing left to do. Leaning against the table Bobby crossed his arms over his chest and bellowed, "CASTIEL! CASTIEL, get down here right now!" He waited glancing around for any signs of movement and wasn't very surprised to find none. Not about to let that stop him Bobby called out, "Fine! You don't want to come talk that's okay with me. But you can at least hear me out. I'm sick and tired of what's going on with the Winchester boys. Dean and Sam are good boys and I don't like what your little war is doing to them. I mean, did you have to tell Dean that he's the one that broke the first seal! The kid was already broken from what happened in Hell, he didn't need that added to it. And yet you expect him to be the strong kick ass demon hunter he once was. Are you looney? Oh, and I know about that little stunt you pulled with the boys making them forget everything and everybody to supposedly show Dean that he was meant to be a hunter." Bobby snorted. "Yeah, like the kid didn't know that already. Dean's a natural born hunter, always has been. He couldn't give up hunting if he wanted to. I know you thought your little reality check would fix things but it didn't. See, you're going about it all wrong. If you want Dean to be the bad ass hunter he was, you need to give him back what made him that way."
"I do not understand." A calm voice softly said from behind him.
"Shit!" Bobby exclaimed. Spinning around he saw a young man in a long tan trench coat staring at him. "Geez, don't you have a trumpet or harp or something you could play before you pop in like that. You almost gave me a heart attack!"
"Castiel cocked his head to one side and gazed curiously at the old hunter. "I am sorry. I did not mean to frighten you."
"No harm done this time." Bobby told him as he dropped back into a chair. "Does this mean you were actually listening to me?"
"I heard but I do not understand. What is it that I need to give Dean?" Castiel asked.
"His little brother, Sam" Bobby replied.
"But I do not have Sam." Castiel stated. "He is with Dean already, is he not?"
"Well yes and no" Bobby answered smirking at the confused expression on the angel's face. "See, Sam is with Dean, but its Sammy he needs." Seeing the angel motion for more, Bobby rolled his eyes and began to explain. "It's like this. Dean's always been the strong, tough hunter for a reason; he needed to protect his little brother Sammy. Even after Sammy grew up and became Sam Dean still felt like he had to protect the kid. It's kinda like the way a father feels about their children and with good reason; Dean practically raised Sammy. Not only is he the protective older brother, he's also the overprotective father. You with me so far?"
"Yes, I understand." Castiel replied.
"Good" Bobby said. "Now with Dean always in big brother/dad mode Sam has always fallen into the little brother role whether he knew it or not. He always followed Dean's lead. But when Dean went to umm, down there, Sam didn't have anyone to look up to or follow. He had to toughen up and take control to survive and he did. And then Dean came back with all his memories intact, which if you ask me, you could have wiped out of his mind. Anyway, the Dean that came back was a mess. So instead of the boys resuming their old roles, they kinda reversed them. Sam's trying to take care of Dean, to be the brother Dean was for him all those years and Dean's letting him. You want Dean to take charge of this mess, you're gonna have to find a way to make Sammy the little brother again. And it's not gonna be easy. Sam's way more bullheaded than his daddy ever was. When that boy gets his mind set on something, it'd take an act of God to stop him."
"You wish me to stop Sam?" Castiel questioned.
"No! No, that's not what I'm saying at all!" Bobby quickly shouted standing and walking toward the angel. "I just mean that you need to find a way to force Sam to be the little brother in the duo again; some way where he'll have to accept Dean's help and protection. You do that and Dean will snap right back into the big brother role he's had for so long."
"Interesting" Castiel stated. "Thank you Mr. Singer. You have been a great help."
A loud bang from outside had Bobby turning to the window. Seeing nothing he turned back to find Castiel gone. Shaking his head he went back to the table and sat back down. He had a feeling he needed to be near the phone.
In a rundown motel outside Watertown, South Dakota
Dean walked out of the bathroom followed by a cloud of steam. "All yours Sam!" he called as he stretched out on his bed hands behind his head.
"Not now Dean." Sam said from his spot at the table. He continued staring at the laptop screen as he rapidly tapped the keys. "I think I might have a lead on…"
"Hello boys." Castiel greeted as he appeared at the foot of the beds.
"Geez, I've really got to get you a bell." Dean grumbled as he sat up.
"What are you doing here, Cas?" Sam asked as he walked around the table to stand between Castiel and his brother. "You got another "little job" for Dean to do?"
"Sam!" Dean warned glaring at his little brother. "Back off."
"It is alright Dean." Castiel assured him.
"No, it's not" Dean disagreed. Standing up he took hold of Sam's arm. "Calm down Sam. Let's just sit down and hear him out, okay?"
"Fine" Sam hissed pulling his arm out of Dean's grasp. Huffing he plopped down on the end of his bed glaring as his brother mirrored his actions.
"Alright, now that that's settled. Let's get this over with. Why are you here, Cas?" Dean asked.
"A friend has enlightened me about the two of you. He has shown me the way I need to precede." Castiel explained as he walked up to the two boys and raised his hands. He lightly touched their foreheads sending both Winchesters into a sleep state. "Now to fix things." He whispered.
A little while later
Dean blinked awake to find himself staring at the ceiling. Groaning he rubbed his eyes trying to recall why he was sleeping in his clothes. A memory of Castiel's raised hand flashed in front of his eyes causing he to sit straight up in bed. "Sam! Sam, you okay?" he called.
"I'm fine Dean" a tiny voice squeaked.
"Squeaked? What the fuck?" Dean thought as he spun around to look at the other bed. He took one look at Sam and burst out laughing.
"Dean! Dean, it's not funny!" Sam whined from his spot on the bed. His little forehead crinkled and his bottom lip poked out. He quickly grabbed hold of his shirt to keep it from slipping off his tiny body. "He made me a little kid again!"
