Sam sat in the corner with his hands over his ears, humming to himself, trying not to hear the horrible sounds coming from the mirror on the wall. Lucifer wanted him to suffer for trying to get information from Charlie about their location. He left the bathroom door and his connection to Sam open so Sam would be forced to listen to every loud slap, every bruising punch, and every heartbreaking wail. Not to mention the grunts and groans coming from Lucifer when he forced himself on her again. He had even tried to flee to another room. But when he ran through the door, the mirror was there on the other side of the room. Room after room, the mirror followed him. He couldn't escape it. Eventually, he collapsed in a heap in the corner of the room, trying to drown out the noises. But it was getting harder and harder for him to pretend it wasn't happening. Until Sam couldn't take it anymore.

"CAS!", Sam screamed. "PLEASE! I'M GOING CRAZY! I NEED YOUR HELP! CAS!" He sobbed, curling into a tight ball on his side. "Please Cas." Sam's pleas had become quite whispers as he wept. "I can't do this anymore!"

Cas was walking back to the table with his arms loaded down with books when he suddenly doubled over, dropping books all over the floor. He groaned, holding his head in both hands. Dean jumped at the sound of hardback books hitting the concrete floor. He flew out of the chair when he saw Cas bent over, holding his head.

"CAS?", Dean bellowed. "YOU ALL RIGHT, MAN?" Cas was breathing hard with his eyes shut tight. "HEY! TALK TO ME CAS!" Cas stood up straight again and opened his eyes. He looked at Dean with deep concern written all over his face. "What is it, Cas?"

"It's Sam", Cas said softly. "He's praying!" Dean's eyes went wide and he grabbed Cas' shoulder.

"H-he's what?", Dean stammered. "Is Lucifer gone?" The look of hope on Dean's face broke Cas' heart. He knew he was about to shatter that hope into dust.

"No, Dean", Cas whispered. "Lucifer still has Sam. He's praying from wherever Lucifer has him imprisoned in his own mind."

"Can you get to him? Can you talk to him? Help him get out?" Dean was frantic. Cas grabbed Dean's arm, trying to calm him down.

"I will do what I can." Cas walked over to the table, sat in one of the chairs, and leaned back with his eyes closed. "I will need silence while I attempt to establish a connection." He relaxed and let his arms drop off the arms of the chair like he had fallen asleep. Dean paced back and forth in front of the table, chewing on his fingernails.

Sam stared at the wall, listening to Charlie being brutalized. Powerless to stop it. When he heard a flutter of wings from the other side of the room, Sam sat up with a start. He jumped to his feet, ran to Cas, and hugged him tightly.

"CAS? I CAN'T BELIEVE YOU HEARD ME!" Sam kept him in a tight embrace, reluctant to let him go for fear he'd disappear. But, he did finally release him and breathed a heavy sigh.

"It was hard NOT to hear you Sam," Cas panted, trying to catch his breath. "You were yelling pretty loud. And I...I could feel your pain when you prayed." He looked over at the mirror where lewd noises could be heard. Lucifer having his way with Charlie. Cas' face contorted in disgust and pain. "I'm sorry you and Charlie are going through this, Sam. If I could take it from you, I would." Sam flashed him a tired smile that disappeared quickly.

"I know Cas." Sam looked down at his feet ashamed that he let himself get into this situation. "Have you guys found a way to get Lucifer out of my body?"

"No", Cas responded, looking away. "We were looking through every book in the library when I heard your prayer. To be honest, I don't have high hopes of finding anything useful." Sam just nodded, looking over at the mirror again.

"Than you gotta find a way to get Charlie away from Lucifer", Sam said. "Even if it means killing me." He looked back up at Cas with a serious expression on his face. "I mean it, Cas." Cas' face scrunched up and he looked away. But he nodded while staring at the wall. "I just can't take seeing Charlie in pain anymore. He's hurting her to punish me, Cas!"

"What do you mean, Sam?", Cas asked with a puzzled look on his face. "Why would Lucifer hurt Charlie to punish you?"

"He let her talk to me through that." Sam nodded at the mirror hanging on the wall behind Cas. "I tried to get her to tell me where we were, and Lucifer caught her trying to tell me. He beat her and right now he's..." Sam clapped his hand over his mouth to keep himself from screaming or throwing up, he wasn't quite sure which. Maybe both. "He...he said he was doing it to hurt me." Cas placed a comforting hand on his shoulder.

"I have ways of tracing Charlie", Cas said.

"Good! Get to it, Cas!" Sam was in a hurry to get this over with.

"Sam, you may be able to expel Lucifer yourself", Cas whispered. "Have you tried looking for a way out?"

"Of course!", Sam yell whispered. "That's the first thing I did! But every door leads to this room!" He ran to the nearest door and opened it. The room was identical to the one they were standing in. Even the mirror was the same, along with the sounds coming out of it. Cas narrowed his eyes at the mirror and walked over to it with Sam following close behind. He studied the mirror for a moment and then lifted the bottom away from the wall slightly, to look behind it. "What's wrong, Cas?"

"I was just thinking." Cas scratched his chin and looked over at Sam. "If this is how Lucifer communicates with you, maybe this is how you get out of this prison he's built. You'll have to break the mirror, Sam."

"I did crack it yesterday. At least I think it was yesterday." Sam wasn't entirely sure what day it was or how long he'd been in here. "But the mirror fixed itself. Now, when I pound on it, it won't break."

"This prison is in your mind, Sam", Cas growled. "You have to use your mind to get out of it!" Sam looked at him, bewildered. He had no idea how he was going to use his mind to break that damn mirror. "This is like a dream Sam! How do you think I was able to come to you without knowing where you are? You have to take control of it. If you can get out of here, you can take your body back, Sam, and kick Lucifer out."

"I'll try, Cas", Sam whispered.

"You have to do more than try, Sam. We're only gonna get one shot at this. If we fail, Lucifer won't give us a second chance. He'll kill Charlie and bolt. Do you understand?" Sam nodded, staring at the mirror. "You can try using the Archangel exorcism to expel him. Cas reached up and pressed his palm to Sam's forehead, searing the words to the exorcism into Sam's brain. Sam jerked backwards, landing on his ass.

"DAMN IT, CAS!", Sam bellowed in irritation. "A LITTLE WARNING NEXT TIME, HUH?" Sam stood back up, rubbing his head. Just as Cas opened his mouth to apologize, they heard a loud bellow and breathy moans come out of the mirror. A moment later they heard creaking noises as Lucifer climbed off the bed.

"I have to go!", Cas whispered. "Don't do anything until I get back to you!" By the time Sam turned to look at Cas, he had already gone.

"I hope you know what I'm doing, Cas!", Sam muttered.
