Sam stands there, paralyzed in the dungeon, with the bottle full of glittering green liquid in his hand. The bottle was strangely cold, almost frozen so to do hurt your fingers if he hold it for a while. However, it contrasts with the dense, oily liquid appearance.
Sam doubted to do. He quickly calculated that Dean will need nearly twenty hours of suffering to reach the desired age, more the time to recover him from the effects of the poison.
He could not cheat Dean. he would have to tell him what was going to happen.
Not was that Dean would have never lied not for "his own good", but he would not do it.
He thought that the sacrifice would be worth in the long run, when he see himself strong and self-sufficient again. But it should decide the Dean himself. He put in the bottle in his shirt pocket and went to the library, where he had left Dean.
larga, cuando se viera otra vez fuerte y autosuficiente. Pero debía decidirlo el propio Dean.

He found Dean sound asleep with his head on a book, boredom or fatigue of the bad nights plagued by nightmares had been more strong than him and had fallen asleep. Further, teenagers need more sleep than adults. Sam remembered reading it, an effect of growth and hormonal instability.
He debated waking him or not. And finally, he decided to let him sleep a little.
He left the bottle and instructions on the big table in the library of men of letters.
He put his shirt on Dean, so he did not stay cold. Sam went to the kitchen to prepare some dinner for them, while he snorting for the concern over it was better to do.
Sam did not know if Dean should eat something, as magical cocktail was not good for the stomach. But as he will not separate of the side of Dean during the time that él remains in coma, he should force himself to eat something and leave brewed coffee for get to stay awake during the long time of the Dean's illness.
He decided to prepare something to eat for Dean too, in the event that he decided not to drink the spell . Sam thought that the best option was that they will use the magic drink.
But the process was too hard and he would leave Dean decide, but perhaps the used its puppy eyes a little.

Sam was hitting an unwilling bite of his sandwich when Castiel made his appearance.
He had felt that Dean was sleeping and he was going to avail this moment, for to talk to Sam about Dean. He wanted to give his opinion over the subject to Sam.
Castiel appeared so suddenly that Sam, that was lost in his own thoughts, he could not help but startled.
"Castiel. Please, you do not show up so suddenly."
"Sam, I need to talk to you."
"Are there problems in heaven?" Sam asked "No in Heaven. There are problems here. I heard your thoughts ."
"That sounds terrible. You cannot get into the heads of the people. It's an intrusion."
"Sorry. It was not intentional. But I'm glad I did because you're going to make a mistake."
"What do you mean?" Sam began to get irritated.
"You must not force Dean to leave his adolescence."
"I think that's not your decision." Sam replied curtly.
"Sam, I pull your brother from the perdition, I rebuilt his body and his mind."
"You mean you know him better than me? What do you know what is best for him that I know it?" Sam was really angry.
"Yes."The angel answered with his usual lack of empathy.
"Look, Castiel. You're a good friend. But Dean and I are brothers. You're get into something that none of your business."
"Everything that affects Dean is my business. Your brother had lost those years of adolescence for taking care and protecting you."
"You want to say me it's my fault." Sam was no longer able keep his voice low.
"Now I have to pay for it and take care of a teenager, assuming a responsibility that I do not want. My childhood wasn't wonderful neither, Castiel. I can not bear this ..."

Castiel interrupted by placing two fingers on his forehead.
"What I mean is this."
The images began to fill Sam's head.

Dean still dazed, lifted his head from book. He could hear voices in the kitchen. He stretched like a cat, opening his mouth and running his hand over his face. he stood up with the intention of going to the kitchen to see who was.
But he only walk a few steps when the voices grew louder, so Dean could hear to Sam that speak very loudly and angry.
He stood still upon hearing the words of Sam.
He came back to where he was before, while his brother's words was resonating in his head:
"... care of a teenager ... I do not want that responsibility, ..., I can not bear to Dean ... Dean is a burden for me ..."
Dean dropped back onto the chair and big tears came out of his green eyes.
When he wiped his eyes with his hand to clear his vision, and caught his attention a bottle that shines in bright green . He got up and grabbed the bottle surprising him its icy touch.
Dean unwrapped the papers around the bottle and he read what it seemed instructions.
He soon realized that it was the spell that Sam wanted so badly, which would restore to him to adulthood.
He recognized the letter of Crowley and he was grieved that his brother had tried with the demon behind to him.
He stared at the bottle. "Well Sammy, I'm not going to make things difficult. It is very clear what you want ". He uncapped the bottle and twisted his nose at his nauseating smell.

Sam was seen in 10 years. Dean prepared his birthday. As always his father was not there and money was tight, but Dean appeared with a cake and a gift.
The lay in the arms of his brother:
"Thank you, Dean! How did you get the money?"
"You do not worry about it, Sammy. Happy birthday little brother! Let's put the candles so you can blow them and open your gift!"
He saw himself getting out of school and into the arms of his brother, crying because bullies had thrown him to the ground and broken his backpack. Dean consoled him and took him home. when Sam did his homework, Dean left. When he returned he had a black eye, but he was smiling.
"Solved Sammy! They will not bother to you again."
Sam ran to embrace him. "Thank you, Dean! You're the best brother in the world."
He saw Dean going to parent meetings, clapping his football team, get standing up and cheering to him in the function of theater, ...
He watched as Dean had dinner, cleaning the house, preparing the weapons of his father, ... While he was doing homework, preparing his exams or went to the movies or birthday with friends, ...
He saw to Dean, with shattered shoes, go to a second hand store. He bought a backpack and shoes for Sam, he looked sadly shoes for him but turned to leave them in their place.
Finally, he saw to Dean washing dishes in a crappy restaurant, he sneaking into seedy bars for betting in the pool. He watched as Dean sometimes getting ejected badly to the establishment. Or as the players, who did not accept to be plucked by a boy, beaten him and took away him the money he had won ...
Sam saw to Dean in dark corners, behind hostess clubs, waiting ..
He saw men coming close to Dean and as they exchanged four phrases with him and Dean put inside his pocket some money that they give him, and so he accompanied to them ...

Castiel removed his fingers from Sam's forehead, and Sam bent like to throw up, breathing hard.
"Sorry Sam, but you did not want to hear me. And that's just what he did for you when he was 14 years old. I can show you more if you want. What he did for you when he was 9 years old, at 16 years, ... But this is what you wanted to say you when I told you that Dean lost those years for you. He did not do it for your fault ... he did it for love of you. "
Sam leaned against the kitchen table to help get straightened himself Little by little, he managed to calm down, but more memories came to his mind: Fireworks of July 4, his escape to Flagstaff, his discussions with his father and Dean always doing peacemaker, paying the piper, ...
He rubbed his face.

"How I can be so selfish!" Sam lamented "That's not, Sam. Only you did not realize what it meant all that to your brother. Dean seemed happy and carefree at the time. But it was only a mask, and he really suffered and felt very lonely in those years. For this I wanted to talk to you, so you give him the opportunity to really get a youthhood, growing up under the care and protection of people who love you and care about him, so he can enjoy the years of young that he lost. If he wants it, of course. "

"Cas, I promise! We will tell us Dean over a possible solution. But if he wants to stay in his 14 years old, then I willingly assumed care of him. I will give him, everything that he could not have then."
Cas put his hand on Sam's shoulder:
"I'll be here for you. Count on me."
Sam hugged his friend:
"Thank you, thank you!"

When they separated after the long hug, Sam dried his eyes wet with tears, and taking dinner he had prepared for Dean. He said to the angel:
"Come, Cas! You come with me to the library. Dean should have dinner and go to bed. Tomorrow will be a good day to talk to him and explain that I do not mind that he is a teenager and that I'll, ... we will be delighted to care to him . But today I want to he can relax and have a good time. Today was a hard day for him ... "
