A/N: Thanks for the response so far for this fic. I was a little nervous because I know this has been done so many times before. I just wanted to take my turn at it because Cas is one of my favorite characters. He's so awesomely tragic, and I have a soft spot for human!Cas as well. I just feel bad because well with Cas human that means no Jimmy. I'll make it up to Jimbo later though.

Chapter Two

Cas really didn't like it when it was Dean's turn. If he thought Sammy was bad, Dean was just as worse. Dean was all over his ass, especially when Cas was taking the pills that the doctors had prescribed to him.

"Would you rather me not take them at all?" Cas asks Dean.

"Ya think." answers Dean.

Cas pops them like candy, without any water. Dean has a future flashback, remembers how Cas turns out in 2014 and he doesn't like it. He never did ask that sonabitch when it all started. He can't help but wonder if it had started now. His future self never told Cas to stop. It wouldn't have done any good. That Cas and That Dean lost what ever they had here. They didn't bother to listen to one another anymore, just exchange sarcastic retorts to see which one came out the biggest asshole. Right now, in this particular moment, Dean had a feeling that he would come out winning this time.

"I have to take these," Cas reminds him. "Dr. Gamble said I have to take four a day."

"I don't give a flyin' fuck what Dr. Gamble told ya!" Dean spats at him.

That ticking time bomb is about to go off. Dean can feel it coming. "If I don't Dean, it won't get any better." Cas informs him as he puts his pill back with the rest of them in the medicine cabinet.

"Yeah, it will get worse!" Dean yells at him.

Dean never told him about what he saw in the future. All he could say when he got back was: "Don't ever change." He thought that would have been enough, but it's not.

This is the one that bugs the shit out of Cas. Dean always thinks he's fucking right. "Dean, you don't-" Cas tries, but Dean doesn't let him get any further than that.

When he was an Angel, he could catch Dean move before he did. He needed that just in case if Dean did something stupid. Now, he can't, and it sucks because Dean has him pinned island in Bobby's kitchen.

"I do know God dammit!" Dean curses at him, his hands tight around Castiel's shirt collar. The best part of all this is with him being human he can actually beat the shit out of him without the pain.

"Get. Off." Cas tries his best to shove Dean's weight off him, but it's useless, like everything else these days gone by. He's no longer stronger than his charge.

"No," Dean argues and slams into the edge of the island.

It hurts because the island is digging into his back. That will leave a bruise later. Oh well, it will just add on to the rest of them. Cas casts his eyes downward even these blue eyes of his no longer have the stronghold as they once did.

"Ya sonabitch, ya better look at me," Dean's hazel eyes have the power now, they draw up Castiel's blue ones. "Ya say I don't know, but I do. Fuck. I wish I didn't!" Dean yells at him. "Cas, what ever doin', ya need to stop. Now!"

Cas just laughs at him like he's the bad end of a very stupid joke. "You think it's that easy, don't you?" he asks of him. "You think I can just turn these fucking emotions off like a switch?" he laughs again. "I can't Dean, I'm not like you!" he spats. "I don't know how to control these damned things in the first place!"

Emotions are new Cas, Dean will at least give him that consideration. Still, it's no excuse. Then it hits Dean. The realization what The Devil had told him. What ever he did, it would come to pass in some sort of way... He can't help Cas. Damned if does, damned if I do as Def Lepp sang once. It hits him with such a force that it causes him to stumble backwards.

"Ya'know what, fine. Do what ever the Hell ya I want." Dean declares in such a cold tone that it makes Cas shiver. He doesn't like to see Dean like this. Never has. However, what makes this time different from all the others is that this time: it's his fault.

Dean left a few minutes after that, leaving Cas alone. He's known loneliness before, but nothing like this. With Dean, he was sure there would be someone there to catch him when he fell, and he was literary, but now, its as if there is no one.

On the road, Bobby can't help but notice how urgent Sammy is to get home. "Where's the fire Sam?"

Sam's the one behind the wheel. "I just don't like the idea of Dean being alone with Cas right now. I think it was a bad idea to leave those two alone with each other."

Bobby sighs.

"What?"

"I can see what yer doin' here kiddo, but the truth is if Dean opens a can a whoop ass on that Angel friend of yers then he's bringin' it on himself."

"I can't believe what you're saying Bobby," Sam retorts. Then again, this was the same man who helped Dean put him in the panic room. "Am I the only one who cares for Cas right now?"

"I ain't sayin' I'm not, and ya should know better than to think that," Bobby points a warning finger his way. Hell, if anything Cas has become like another son to him, Angel or no Angel.

Sam grips his hands tight around the wheel. They don't get it. They don't understand what Cas is going through. He does.

The rest of the way back was silent.

"Cas?" Sammy questions when he enters Bobby's house.

He doesn't like the silence that answers him back. It's eerie, like before... "Cas!"

Bobby follows him. It was also too quiet for his liking. "Where's Dean?"

"He's not here."

Sam is relieved when he finds Cas in the entrance way.

"Ain't he suppose to be watchin' ya?" Bobby asks him.

"Yup."

Sam sees that he has a beer in his hand and it's almost empty. Sammy exchanges a worried look with Bobby. Dean was pissed off and off somewhere. That's probably a good idea. At least, Sammy thinks so. Bobby doesn't.

"I'm goin' see where that idjit has gone off to." he declares and goes to pull out his cell to find his oldest. He goes off to give some alone time for Sam and Cas.

"How long have you been by yourself?" Sam demands.

Cas shrugs. "A couple of hours, give or take."

Sam doesn't like that answer. That's more enough time to do anything, and Sam searches with his eyes to see if there are any new cuts anywhere on Cas. It's hard to tell because now Cas has long sleeves. Damn winter.

"I didn't do anything," Cas assures him but he doubts that Sammy will believe him. Which he doesn't.

"I want to check," Sam demands.

Cas doesn't get a chance to argue. Sam gives him a full out body search. It's humiliating but what else is new? "I told you," Cas says once Sam is done and he pulls back on his shirt.

"I just wanted to make sure," Sam tells him.

"Feel better,"

Sam nods.

"At least one of us does." Cas replies, and tosses the beer he's finished only to get another one.

"Um, Cas..." Sam isn't sure that's a good idea.

Cas only response is: "Want one?"

It's dark by the time Dean comes home, he's drunk, and Sammy is the one waiting for him. Bobby has Cas covered. "Where the Hell have you been?"

"Out." he stumbles forward, Sam catching him.

"I can see that." he shakes his head and tosses his ass into the nearest chair.

"Why ya gotta be so rough with me Sammy?" he asks with a hiccup.

"You were suppose to be here." Sam reminds him. "Watching out for Cas!"

"Well, coulda, woulda, shoulda,"

"Oh, I'll coulda, woulda, shoulda," Sam threats with a balled fist towards his big brother's direction. The only reason why he's not is because the sonabitch is drunk. "Do you have any idea what could have happened to him in the time you weren't here?" With that said out loud, Sam was stupid for only checking for cut marks. As soon as he was done with Dean he was so going to check up on Castiel's pills. Cas had no idea that he was keeping up with him behind his back. As for now, Cas was doing as the doctor said so.

Dean shrugs like he doesn't care, which deep down, past all the booze, he does. That makes it hurt worse, but what Sammy doesn't understand is that they can't do anything. It's only going to get worse from here on out. What's the point? He's all ready failed Cas.

"What aren't you telling me Dean?" Sam demands, catching those hazel eyes that are filled with guilt and blame. He's seen that look before. In fact, he's seen that a lot since Dean took that Back to the Future trip with Zachariah. He hadn't said much, just kept Cas within arms length.

"It doesn't matter." Dean spats at him.

"The Hell it doesn't! If has something to do with Cas, it does!" corrects Sam.

That's when Dean laughs. "It really doesn't."

Sam wasn't finding any of this funny.

"Talk 'bout the blind leadin' the visually challenged." continues Dean, closing his eyes. He hopes that will get his world to stand still.

Sam crosses his arms. "What's that suppose to mean?"

"Ya, baby brother," Dean points at him, opening his eyes. "Couldn't save ya, and guess what we can't save Cassie either," Then that's when Dean lets the cat out of the bag, and shares with Sam what he saw in 2014.

So, that's why Dean had been acting so odd around Cas of late. Now, he understands. He sighs, goes to his brother on bended knees. "The past is done with Dean. We can't do nothing about that, but the future we can." he shakes his head. "You don't know how true that future will turn out to be. Zacharia was dick. He was probably trying to scare you and by the looks of it, he's done it. Don't let that jerk off win, and don't give up on Cas so easily either. He's a lot stronger than anyone or himself is giving credit for."

This why Sam was one Hell of a baby brother. Not only did not forget the pie, but one look of those puppy dog eyes and words of encourage. Dammit at all if he didn't believe him. Sam was good at giving people hope, even him.

After his brother was taken care of and in bed, Sammy went back down to check up on Castiel's candy store. His eyes went wide with worry as he what feared came to pass: there were more than a few pills missing.

TBC...

A/N: Two things. One: Guess who I named Dr. Gamble after. Hum... LOL! Had to do it because Sera Gamble is my hero and wanted to name a character after her even if it was only a mention of thing. Two: "Talk about the blind leading the visually challenged." Is a Methos quote from Highlander. Had to borrow it because its one of my favorites.
