Sam's screams could be heard for almost an hour, making Bobby, Dean, and especially Carly uncomfortable. Yes, she still was pissed at Sam and equally as angry about him drinking Ruby's blood, but hearing Sam beg to be let out broke her heart. She was tempted to run down there and unlock the door, but in the end she knew the better choice was to wait it out. When Sam was free from the demon blood, he'd be clear minded and better for it.

Castiel had disappeared shortly after the four went upstairs, going off to do whatever he did when he wasn't with them. Bobby provided Carly and Dean with alcohol to try and distract themselves from Sam's pleading, but Carly refused. After the last few days, she wasn't at 100% and she didn't feel like adding to it. Dean on the other hand took Bobby's offer with open arms drinking until he could barely think straight.

When it went silent, that was more nerve wracking than the screaming itself. Was he hurt or just too tired to use his voice? All of them felt the urge to go check, but doing so may cause them to break and let Sam out. Saving the world from the apocalypse was more important than Sam's discomfort, even if it made the others feel awful.

They kept their distance as best as they could, but nearly six hours later the yelling started up again with a crash. The three looked at one another knowing it could be a trap, but they had to make sure. So, they booked it down the basement steps. Bobby put in the code as he threw the door open. What they found was horrifying.

Sam was seizing on the floor with veins of black snaking their way up his throat and onto his face. The three ran to his side, Dean and Bobby holding down Sam's arms as Carly looked on with concern.

"What's happening?" Carly asked, looking from Bobby to Dean and back again.

"I...I don't know," Bobby said, shaking his head. "I've never had to deal with detoxing someone of demon blood. I don't know if this is normal."

"This cannot be normal. I mean his veins are black for hell's sake!" Dean yelled.

Sam's seizuring got worse as he knocked Bobby and Dean away with his hands. Then as Carly took a step forward he flew upward, his back hitting the wall with such a loud bang Carly screamed. He stayed there a few inches off the ground for several moments before he began barrel rolling across the wall, knocking stuff off the table with his feet.

He nearly made it all the way around the room before Dean and Bobby caught up to him. They each grabbed an arm and yanked him from the wall. He fought against them the entire way, but neither were going to let go, not this time. The two got him back onto the bed and held his squirming frame to the ratted mattress.

Dean turned toward Carly. "I need you to get the handcuffs from the trunk of the Impala."

"You're gonna handcuff him to the bed?" Carly asked with wide eyes.

"He needs to be restrained before he hurts himself. Now go!" Dean snapped, placing the keys in her hands.

Carly looked down at them before nodding. She ran from the room and up the stairs, almost tripping on the way up. Carly got to the front door, slamming it open as she made her way to the trunk.

She lifted the compartment hatch and searched through the contents of weapons, ammo, and general supplies. She found the handcuffs hidden in the back. She grabbed two sets and slammed the trunk shut before hightailing it back into the house. When she returned to the basement, Sam was struggling just as hard as he was before.

Carly gave the handcuffs to Dean who then handed one to Bobby. She held Sam down the best she could while Dean and Bobby attached the cuffs to Sam's wrists and then the bed posts. It would keep him restrained until they figured out something better.

Once chained up, the seizing stopped as his body relaxed against the mattress, his eyes closing. Bobby, Dean, and Carly made their way out of the room, looking at Sam as they did. When they were back upstairs, Carly couldn't stay quiet.

"What if this doesn't work?" Carly asked.

"We'll burn that bridge when we get to it," Dean sighed.

Bobby placed his hands on the desk and leaned forward. "I know you care about him, Dean. I mean he's your baby brother...but if this doesn't work and he strengthens up, he will start the apocalypse. We cannot let that happen."

"I know," Dean muttered.

"So, if it comes down to it you know what must be done. Right?" Bobby asked.

Carly spoke before Dean had the chance. "You cannot seriously be considering killing Sam!"

"It may be the only choice we have," Dean said.

"He's your brother!" Carly yelled.

"I know, okay! I know…" Dean snapped, running a hand through his hair. "You think I want to kill my baby brother? He is all I truly have and losing him would break my heart into so many pieces that I would never be able to truly fix it, but if it comes down to him and saving the entire world...I have to choose the world."
"This is utterly insane!" Carly sighed.

"Yeah, but if you think demons are bad...Lucifer is even worse. If he is released, the world ends as you all know it," A gruff voice said as the three turned around to find Castiel leaning up against the wall behind them.

"Are you here to judge, Cas?" Dean asked, turning toward him with crossed arms.

"No, I've come because I'd like to have a personal chat with you...somewhere private," Castiel said.

Carly and Bobby looked toward one another with raised brows. It honestly sounded like he was inviting Dean to a date of some kind. They both knew that wasn't the case, but it made them smile just a little bit at the thought. Dean was thinking the same thing and gave the two deadly glares before looking back at Castiel.

"What do you want to discuss?" Dean asked, ignoring Bobby and Carly's smiles.

"That will be something we can talk about once we get there," Castiel said.

"Get there? Get...where…"

Before Dean could finish, Castiel and him were gone. Once they disappeared, Bobby and Carly went back to passing the time. Hours went past and Dean was still gone.

Later that night, Carly took the couch as Bobby went up to his bedroom to get some rest. Carly tossed and turned, but she couldn't get herself to fall asleep, knowing Sam was handcuffed to the bed downstairs. Her resolve broke and she got up from the couch, opening the door to the basement and sneaking into the depths below.

Carly tiptoed down the stairs and made her way over to the door. She placed her ear against the cool metal, hearing the sound of crying through the material. The sound of this caused Carly to fully crack. She had watched Bobby put in the code earlier that day when they came down to secure Sam, so she quickly typed in the code as the door clicked.

She placed her hand on the handle and with a sigh, pulled the door open. Sam was crying beneath his breath. She moved around the bed, kneeling beside him. The second she placed her hand on his arm, Sam's eyes shot open.

"What are you doing in here?" he whispered.

"I heard you crying and I wanted to make sure you were okay," Carly said.

"I won't be okay until I get out of this horrid room," Sam muttered.

"You know you can't leave until the blood is gone," Carly sighed. "It's better this way."

"And why is that? None of you have told me why you are doing this. I understand not wanting me to drink demon blood, but this seems cruel," Sam pointed out.

"I know it may seem that way, but when your mind is clear of the blood's control you will understand why we did this," Carly said.

"My mind is clear and I know what must be done, even if none of you can see it," Sam said.

"What you think is right is far from it. You have to understand that."

"Oh, I see everything clearly and I understand fully well, which is why I am sorry."

"Sorry for what?" Carly asked with a scrunched brow.

"This."

Sam lifted his hands up as the cuffs came loose from his wrists. They clinked against the bed frame as Carly's eyes went wide. She shot back onto her back as Sam held a bobby pin between his fingertips, flinging it across the room.

"You really need to be more careful with what you leave in your pockets, Carly," Sam said, rising to his feet. "You dropped this earlier when you, Dean, and Bobby restrained me to the bed. It didn't take me long to undo the locks, but I wanted to wait for you to come check on me because I knew you'd be the first to break."

Carly crab walked backward away from Sam as he caught up to her. He grabbed her by the throat and lifted her with ease, slamming her back into the wall so hard something from the table fell onto the floor. Carly's hand rose to Sam's as she tried to pry it away, but that just made him squeeze harder.

"Sam...stop this…please," Carly gasped.

"I can't until I kill her," Sam said, leaning down and grabbing a shard of glass that had hit the floor when he punched the mirror earlier that day. "And I need the strength to get out of here."

"Sam, please...this isn't you," Carly gasped.

"Oh, it is me...the real me and soon you will understand what I mean, but for now try not to struggle...it'll just make this hurt more than it has to," Sam said.
