Sam stared at the floor as he listened to the voicemail once again.
"Listen to me, you bloodsucking freak. Dad always said I'd either have to save you or kill you. Well, I'm giving you fair warning. I'm done trying to save you. You're a monster, Sam, a vampire. And there's no going back."
He pressed the button to play it again, and wondered why he was torturing himself like that. As he was about to repeat it, he heard the fluttering of wings, and looked on the bed beside him.
"Cas?"
"Hello, Sam," The angel said, "How are you?"
Sam shook his head.
"Dean will be here in a few minutes," He seemed to shudder at the mention of Dean, "What did you want?"
Castiel thought for a moment. What DID he want? To ask Sam out? To tell Sam he was in love? Does Sam even feel the same way?
"It's not that important," He concluded, "Why are you upset?"
Sam played the voicemail again, unable to look at the angel. Cas was confused.
"Why would Dean say something like that?" He wondered.
"Maybe he was upset," Sam defended.
Sam winced when the older brother entered the hotel door with a bag of groceries, "Hey, Sammy! Cas, what are you doing here?"
Castiel just glared at him.
"What?"
"Sam, please hand me your phone," Castiel didn't take his eyes off Dean.
The younger brother reluctantly handed Cas his phone, then typed in the voicemail password when the angel got confused. Dean grew horrified as that horrible message was played in his voice.
"Sam, I…"
"It's okay," Sam lied.
"No," Dean said, "I never said that. I would never say that, I'd never kill you."
Castiel squinted, thinking.
"Perhaps," The angel began, "Zachariah manipulated the recording."
"Or Ruby," Sam said.
"You really thought I'd…" Dean started, "Sam, no."
Sam deleted the messege from his voicemail.
"What did you really say?"
"I told you that was sorry. That Bobby spoke some sense into me, as usual."
Sam laughed and hugged his brother, who turned to the angel.
"So, why are you here, then?"
"I wanted to speak to Sam," Castiel answered, "Um…alone."
"What are you going to say that you can't say in front of me?" Dean challenged.
The angel nodded, "All right," He moved toward the younger brother, "Sam, I have had these feelings…for you."
Sam looked at Castiel in fear, Dean looked at the angel with a sudden rage.
"What kind of feelings?" Sam asked.
"You humans call it love," Castiel said.
"No," Dean interrupted, "Get the hell out, now!"
Castiel shrunk away from the older brother, while Sam gave Dean a hurt glance.
"Dean, just hear him out!" Sam said.
"No," Dean approached the angel, "You leave Sam out of this! He will not be manipulated again."
"Dean, I am not…"
The older brother grabbed the angel by his trenchcoat and nearly pulled him up off the floor.
"Get out," He said, "Or I will beat the ever-loving shit out of you, until you'll wish you were dead."
Castiel nodded in understanding, Dean set him down, and he disappeared.
"Dean!" Sam yelled.
"Forget it," Dean said, "I don't know why Cas is doing this or what he wants…"
"He wanted to talk to me!"
"Forget it, Sam!"
Sam growled in frustration.
That night, Sam was up late, as usual, when Castiel fluttered in quietly.
"Cas?" Sam whispered.
"Is Dean asleep?" Castiel whispered.
"Yeah. What did you want to tell me earlier?"
"I was saying that I love you, Sam," The angel stated, "Understandably, your brother thinks I am trying to manipulate you. I do not wish to hurt or trick you, Sam. I only wanted to know how you felt."
"How…how I felt?"
Sam had never thought about how he felt for Castiel. Of course, he was glad to meet an angel. The angels, however, turned out to be manipulative, similar to the demons. Then again, Castiel defied angel's orders to help the Winchesters. Sure, Castiel's vessel, Jimmy, was attractive, though Sam had to admit he felt a certain admiration for that specific angel.
He reached out his hand out to Castiel, grabbing the angel's and interlocking their fingers together. Sam hadn't felt this happy holding someone's hand since…well, since Jess.
They slept together, literally. Sam's arms were wrapped around the angel under the blankets, Castiel's trench coat folded neatly at the foot of the bed. He left before Dean woke up.
"You're not taking Sam Winchester," Castiel threatened, nearly stepping out of the circle of holy fire.
"What's wrong, Cas?" Lucifer taunted, "Afraid your boyfriend is gonna get hurt? It's okay, I won't ride him too hard."
"I'll kill him," Lucifer taunted Sam when he became the vessel, "No, I'll torture him, slowly."
"Leave Cas alone!" Sam demanded.
"And Dean…I'll fry him. Your brother's blood and guts will be all over you when I'm through with him."
"Leave my brother alone!"
Castiel exploded, Luci killed him. He tried to help, and this is what he gets. Sam whimpered from the inside, fighting to take control.
Sam killed Bobby, then nearly killed his brother. Technically, it was Luci, but that didn't ease the guilt. Sam jumped into the pit, it was the only way, and Adam tagged along.
Next thing Sam knew, he was in Hell, the damned cage. Luci turned on Sam almost immediately, and begun burning and roasting the man's skin. He screamed, only able to smell his own burning flesh. Dean was right; they peel and rip until there's nothing left, then it begins all over again.
Micheal tried to stop it, to protect Adam and Sam, "Brother, stop. This matter is between you and me. Leave the humans out of this."
"But the humans are the best part," Luci taunted.
Lucifer would knock Micheal out, allowing him to torture both Sam and Adam in new and "fun" ways.
His favorite person to torture was Sam, and his favorite way to torture him was disguise. The way Sam would scream and beg "Dean" or "Castiel" to stop.
At some point, Sam's body was separated from his soul, and tossed outside the cage like garbage. The newly soulless body was confused, and left with nowhere to go.
Enter Castiel, who decided he couldn't live without Sam. There were no commands from the other angels on what to do with Sam or Dean or their souls, due to the war breaking out in heaven. He decided, by himself, to trudge through Hell, find the cage and drag Sam out.
It took a while to find the cage, at least, a while in Hell time. When Castiel reached it, Michael handed Sam's body to the angel, forgetting about the soul.
"Hurry," Michael said, "I beg you, before Lucifer sees."
Castiel nodded and took the body, while Sam's soul tried to scream for him.
"Shh," Lucifer put his hand over the soul's mouth, "You're mine. Forever."
He petted Sam's hair.
