(based off the season 7 episode 2 of Supernatural)

After having his wall broken in his head, Sam has been seeing Lucifer and he has told Sam that he is still in Hell with him, locked in the cage. Sam is unclear about this, Lucifer explains that this is his best torture yet, allowing Sam to believe that he got out of the pit and back into his normal life only to reveal or remove the wool over his eyes to show that he is still in Hell, burning. Dean and Bobby notices Sam not acting alright and after losing Cas and having these new creatures from purgatory that they know nothing about they turn to look at Sam and to see all the damage before them.

Dean- "Yeah well, now onto our other big problem. Who you doing and do not say okay?

Sam- "I'm not okay."

Dean- "You think!"

Bobby- "Hey, go a little easy."

Dean- "There's nothing easy about it Bobby, okay. We acted like he had everything under control."

Sam- "I get it, I'm sorry. I... I didn't exactually want to crack up, you know?"

Dean- "What the hell happened back there?"

Sam- "Well, its not just flashbacks anymore."

Dean- "Well then what?"

Sam- "It's more like, I'm seeing through the cracks."

Dean- "What does that mean?"

Sam- "It means I'm having a difficult time figuring out what's real."

Dean-''Hallucinations?"

Sam- "For starters."

Dean- "Well for starters, if your tripping Hell's bell why would you hide that?"

Sam- "I wasn't hiding it Dean. I was just not talking about it. I mean It seemed like you two had enough going on as it was. I just figured to hold onto the safety bar and ride it out you know, but it's getting more specific."

Dean- "As specifically what?"

-Sam begins to tell Bobby and Dean that he has been seeing Lucifer and he has been tormenting him and dangling this idea that this place is not real.

Dean- "What the hell Sam?"

Sam- "I told you."

Dean- " I mean seriously, how do you argue with that?"

Sam- "I know. It's a problem."

Dean- "No wait I got it. Why would the devil hollow deck you a whole new life, when he can just kick your ass all over the cage?"

Sam- "Cause as he puts it: "You can't torture someone who has nothing left for you to take away""

Lucifer- "Very good Sam."

Dean- "Okay fine. But this Malibu dream mansion that he, he makes for you to take away is this post-apocalyptic mess?"

Lucifer- "It had to be a mess Sam, or you wouldn't believe it was your life."

Dean-" Wait are you seeing him right now?"

Sam nods his head yes.

Dean- "You know he isn't real right?"

Sam- "He says the same thing about you."

Dean turns to look over at Bobby for help and answers. Bobby has always been there for the boys and Dean right now was unsure what was going on and how to solve the new problem before them, which was Sammy.

Bobby- "I'm going back to work."

Dean now had no clue what to do with Sammy but he knew he must keep a close eye on his little brother, cause the other shoe always drops and he wanted to be there for Sammy and protect him the best way that he could.

Bobby and Dean went back to work on the new monster problem while Sam slept a little bit. Sam finally woke up and looked around the room not seeing Bobby's house but meat hooks and fire. He heard laughter and screams off in the distance then he got a sharp white hot pain along his body as it slowly became covered in flames. He then sat up quickly waking up from his sleep only to see Bobby looking at him. Bobby sat in the kitchen with stacks of books before him. He looked at Sam with curious eyes.
Sam's breathing was not regular. He thought he was already wake but he just woke up now and is in Bobby's house, but he couldn't be sure that this was truly real or not.

Bobby- "You alright there boy?"

Sam- "Yeah. I'm good."

Bobby- "Good."

Bobby went back to work and Sam looked around the room. He had told Dean what was going on but the truth was he didn't know if anything he was seeing at this very moment was real of just apart of his torture by Lucifer. Sam cleaned his gun and helped Bobby as best as possible, Dean was out looking for clues and answers when Bobby got a call from Jody Mills saying her doctor was a monster, so Bobby left and Sam was stuck alone inside a place that he has felt like his only ever home, but now these familiar walls and books weren't giving him a safe feeling. Sam feared that this was all false and that both Dean and Bobby weren't real and the thought of that was depressing. If this was all fake then he was still in Hell and Dean was alone on Earth. Sam felt Lucifer snap Bobby's neck and seeing his body slowly fall to the ground and having Cas blowing up into a million pieces. Then seeing his big brother's face, soo much pain and sadness was held in it. How much he thought he was doing the right thing, which he was. He was saving the world and mainly saving his brother but he was also doing harm too. He had killed a man who was there for both him and Dean when their own father wasn't and then his newly found friend, Cas.

Sam was upset. He had no idea not one, he didn't know if the house he was in, was real let alone the floor he was walking on. Everything looked and felt real but that single thought that it all could be fake, over powered all of his other thoughts and sences. He could taste beer and read the words on the pages of the books but he also could see meat hooks and Lucifer. All Sam wanted was to know what was real and not. Yes the idea of being with Dean again was great and a big wish of his. And being with Dean was one hundred times better than being cooked in Hell, but then again seeing his brother's face everyday and not having it really be Dean was more painful than him stuck in the cage with Lucifer and Michael and getting his ass kicked forever.

Sam saw Lucifer reading in the corner of the room and he questioned everything that has happened. Everything since the fall in the field. Getting out of the cage was impossible, he knew he wasn't coming back he told Dean that. (5x22)
Sam- "You know I'm not coming back?

Dean-"Yeah I'm aware."

Sam-"So you got to promise me something."

Dean-"Okay. Yeah anything."

Sam-"You got to promise not to bring me back."

Dean- "What??? No! I didn't sign up for that!"

Sam- "Dean."

Dean- "Your Hell is gonna make my tour look like graceland, you want me to sit by and do nothing?"

Sam-" Once the cage is shut, you can't go poking at it Dean. It's too risky!"

Dean- "Nah nah, nah No! As if I'm going to let you rot in there!"

Sam- "Yeah you are. You don't have a choice!"

Dean-"You can't ask me to do this."

Sam- "Sorry Dean you have to."

Dean- "So what am I supposed to do?"

Sam-"You go find Lisa, you pray to God she is dumb enough to take you in. You have barbeques and football games, you go live some normal apple pie life Dean. Promise Me!"

Sam knew very well that Dean had promised him, but he also knew how hard it took Dean to do that. He was Dean's whole world and Dean only ever knew of was hunting and protecting him. Sam thought it over and over in his mind.
"Could Dean have gone back on his promise to him, if that meant saving him? And what would that cost him? His soul? His mind? What would it cost his brother? Another trip to Hell? "

Sam couldn't think of a straight answer. He had no idea what was real and if Lucifer was just a part of his mind leaking memories because of the wall coming back down after his soul was placed back in him, after Dean made a trade with Death. Then, this place, everything, was real but then again he couldn't truly know and had this horrible feeling as if it was all fake, and he was still stuck in Hell like he had plained on being and Dean had followed though with their promised they made. Yeah Sammy didn't want Lucifer to get free but now he badly wished that somehow, some way he did make it out of the cage and was back living the life he has always had, fighting monsters by his big brother's side.
