Dean came to a stop a couple yards away from the building Cas had found. He was right when he said it wasn't abandoned. The upstairs windows were lit up like a christmas tree and it made Dean frown. It was a good size building, modern windows and doors, more like someone's house especially with all the lights. But the outside looked dirty with brown grass and thick trees surrounding the entire building ans no pathway to be seen. If it wasn't for Cas noticing the angel sigils then he knew they wouldn't have even thought to check out a building like this. The son of a bitch did his homework, he thought as he climbed out of baby and made his way to the trunk. He hadn't noticed the demons posted outside but he trusted Cas when he said there were two of them. He reached in and grabbed a couple angel blades, throwing one to Sam. "Plan?"

Cas was staring at the building intensely, his brow furrowed. "I can hear her but it's still very weak. Almost like a whisper." He turned to looke at the boys. "She is definitely in that building. She is calling out Sam's name."

Sam glanced at Cas in surprise. "My name?" Cas nodded. "She has been in love with you for years so it is of no surprise she is calling out for you." He stared at Cas for a beat before he looked down then back up at them both. "We need to take care of the demons outside firat. But we don't want to shout out our arrival." He looked at Cas again, "Can you kill them both without drawing attention to us?" Cas nodded. "It would be a pleasure."

He turned to Dean was was watching the building. "Dean, we need to get inside that building as quickly as possible and as quietly as possible. Determine how many demons we are dealing with before we look for Ada." He frowned as he looked back at Sam. "We need to find her asap Sammy. You heard Cas, she's calling out for you dude. The longer it takes the more likely it is he will kill her."

"I know that. Believe me when I say I want to storm that building and get Ada to safety as soon as possible. But we don't need demons on our ass when we are trying to escape with her. We will kill them all as quickly as we can and pray she is still alive." He sighed and rubbed his face. "I love her Dean. And I want to get her out of there as much as you do. But we need to do this properly or it won't matter if we get to her quickly because then we will all be dead. Helping Ada while being surrounded by demons isn't an ideal plan."

"I know Sam. I know." He grabbed two cans of black spray paint then looked at Cas. "We will destroy as many sigils as we can. The minute you can get inside, go straight to Ada." He slammed the trunk and cracked his neck from side to side. "Lets do this."

The boys watched as Cas did his work, appearing behind both demons and smiting the life right out of them. He looked up towards them and nodded, indicating to them to start their plan. They both ran as steathily as they could to the double wooden doors at the front of the building. Standing either side, Dean nodding at Sam as he reached for the doorknob and slowly turned, opening the door as quietly as they could. They both stepped inside, angel blades at the ready, Sam closing the door behind him with a small click. The corridor was dimly lit as they crept along, shadows in every corner. There were doors on either side of the hallway and a grand staircase in the middle of the right wal wall leading to the rooms upstairs. They each took a side, trying each doorknob only to find that the rooms were empty, bar the sigils on the walls which they sprayed with a large black cross rendering them useless. They looked at each other when they heard footsteps walking down the stairs, at least two sets of them, before hiding in the shadows underneath.

"Why are we still here?" One of the demons whined. "It's been days! It's not like we are the ones having all the fun torturing that sweet piece of Winchester ass."

Sam stiffened, his jaw clenching with anger as he took a step forward ready to end the demon but Dean pulled him back. "Not yet," he whispered, looking back up at the stairs, watching as the two demons made their way down.

"You know she's not related to them, right? How one of those puffed up dicks haven't had their own bit of fun with her is beyond me. Anyway, we need to keep a look out for them. Boss doesn't want them to get in the way of his 'fun'."

The boys stepped out of the shadows smiling. "You got that right." Dean said as he plunged the angel blade into the first demons chest, Sam following by stabbing the other in the neck. They let the bodies drop to the floor as they rushed up the stairs, three more demons walking round the corridor. "Hey!" Dean shouted, getting their attention. "Which one of you dick less sons of bitches wants the first ticket back to hell?" They braced themselves as all three demons raced towards them. Dean managed to stab the first after dodging a punch, throwing the body at the second demon running towards him, making him fly backwards into a wall. Sam had taken a few punches and when Dean glanced back over at him, he watched as the third demons hand wrapped around his throat, lifting Sam off the ground a little. Dean raced over to help but Sam had it in control as he brought up the angel blade and rammed it into the demon's chin, dropping to the floor along with the flashing body. He looked up at Dean, breathing hard, as a scream echoed down the corridor. The other demon had pushed off the body and rushed towards Dean, catching him off guard with a punch to the side of his face. He raised his hand and rubbed his jaw. "Big mistake," he growled as he punched the demon in the face, pushing him backwards. He quickly glanced back at Sam. "Go. Find Ada. I can handle this dick."

Sam nodded and raced down the corridor. Dean got in a few more punches before the demon raised his hand and flung him back against the wall, his body hitting it with a loud thud before falling to the floor wincing. He looked up at the grinning demon, who had walked over to him, giving him a good hard kick to the stomach. Dean's breath flew out of him and he felt a little lightheaded as he tried to catch his breath. He gripped the angel blade tight, hiding it under his jacket as the demon bent down. "Not so much a smart ass now are you?"

Dean smile. "I guess not," he said before stabbing the angle blade through the demons chest. "But then again, I'm not the one with an angel blade through his chest. Dick." He pushed the body away while simultaneously pulling out the angel blade, orange flashing lighting up the corridor. He got to his feet and destroyed the rest of the angel sigils. Cas appeared instantly next to him, making him jump a little. "Little warning next time?" Dean griped.

"I apologise."

They could hear scuffling and shouts from the room Sam had ran into, and they rushed down the corridor towards the fight. Cas stopped abruptly at the door, taking an unsteady step backwards. "Cas?" Dean grabbed his arm to steady him. "I cannot enter the room Dean. Angel sigils are covering the walls." He said as he leaned backwards against the wall. Dean sighed. "God damn it! Stay here for when we get Ada. We are going to need you." He ran inside to see Sam stab the demon in the chest, his body falling to the floor flashing with Sam still stabbing him, over and over again. Dean ran over to him and pulled him off. "Sam stop! Ada..."

Sam looked over at the table she was restrained too. "Oh god," he stood up and rushed over. She was covered in blood, cuts and deep wounds all over her body, skin hanging off her stomach and a large stab wound in her side. Dean automatically started to remove the restraints as fast as he could. "Ada? Hey, come on, wake up. Let me see those pretty eyes Ada," Sam stroked the side of her face gently as her eyes opened slowly. He swallowed back tears as he gave her a small smile, pain evident in her face. "There we go," he said softly.

"No...no...you're not real..." she croaked as she tried to move away from him. She let out a cry of pain at the movement. Dean managed to untie her and she slowly lowered her arms to her chest. She looked at both boys in fear as she tried to sit up on the table, her breathing laboured from the pain coursing through her body. She touched her side gingerly before raising her hand to look at the blood. "Sam..." He ripped off his short and pressed it onto the wound in an attempt to stop the blood flow. "Press here as hard as you can, Cas is just outside the room." S cried out as she did as instructed, but she was too weak and the shirt fell to the floor. Sam scooped her up into his arms and ran towards the door. Dean got there first, making sure they could get to Cas without any obstruction.

"Sam," Cas yelled, his eyes beginning to turn blue but fused out as he swayed on his feet and grabbed the wall to steady himself. "That is not Ada."

Sam looked down at her in his arms. "What? Come on, she needs help Cas." She was barely conscious, her body limp in his arms. Dean turned to look at her, "Cas are you sure?"

"I can see her demon face."

Reaching into his pocket for his holy water, he threw it over her. Sam dropped her to the floor when her skin sizzled and she hissed, her eyes flickering to black. She slowly stood up and dusted herself off as Sam backed away to stand next to Dean. "Winchester's," she said grinning. "Always a pleasure. And Castiel. The scoobie gangs all here."

"Get out of her," Sam growled, taking a step forward, Dean gripping his angel blade tightly. Ada crossed her arms and tapped her chin with her fingers. "Well, I could but I don't think your little sweetheart will be alive if I do. See I have thoroughly enjoyed my time with her," she said as she ran her finger down her neck and stopping at her chest, "we've shared some special moments together as I peeled off her skin." She looked down at the flapping skin, holding it between her fingers and she peeled it off completely and tossed it to the ground. "we're besties."

They felt helpless, unsure of what to do but they knew they couldn't do a thing while he was in her body. "Just let her go, you've had your fun," Dean said through gritted teeth. She laughed as she peeled another bit of skin from her stomach. "Oh, but there is still so much fun left to be had! I know all her little secrets. She turned to Sam. "She is so in love with you it makes me nauseous. Even after all the times you broke heart, all the times you disappeared for months or years at a time, she still loved you. It's disgusting. The thoughts she's had of the two of you together, let's just say PG13 wouldn't cut it. And you," she looked at Dean, "she admired you, looked up to you as her big brother, her protector. Even though you and jolly green standing next to you have forgotten her on countless occasions. She has so much self pity, so much hatred for herself that if I had a soul, I'd be shipping her off to a shrink."

"get out of her, or I will kill you," Sam said, guilt filling him up as he held his angel blade in front of him. Ada stepped forward until the blade was pressing into her chest and smirked. "Go ahead. You won't do it. Not while I'm inside her. Shall I give you an incentive?" They heard a loud crack followed by a cry as Ada twisted her head to the side, breaking her neck. "Did you hear that crack Sammy? You still going to kill me? I mean, without me, she'd be nothing but a bloody, rotting corpse on the ground."

Sam took a deep breath, the angel blade shaking in his trembling hand. She was right. He couldn't kill her. He stepped back, dropping his hand to his side and stood next to Dean. "If she's already dead then it doesn't matter if we kill you." Dean countered, even though he knew he did't want to have to kill her either.

"Hmmm, true. But she feels so good. I might keep her, it'd be good for business knowing I'm using the Winchester's pet as my meat suit...plus the bragging rights alone! She's begging for death. Screaming at me to kill her." She taunted. "Why don't you hear her for yourself." Her head lowered to her chest for a minute before she looked up. "Sam? Dean?" She took a step forward then stopped abruptly. "He's inside me isn't he? I shouldn't be able to stand, let alone walk. He burnt the soles of my feet so that I couldn't escape."

"Sweetheart I'm so sorry." Dean said softly. "I'm sorry for everything. I should have been there for you more. We will get him out of you," All Sam wanted to do was take her in his arms, get that demon out of her and never leave her side again. "Ada, I love you,"

Her eyes turned black and she laughed. "Aw, you're both so sweet. But it's time to go I'm afraid. Seen ad neither of you will be killing me anytime soon while in this body, I'm not going to be leaving her for aw..." Sam stepped forward and plunged the angel blade into her stomach, sobbing as he did so, her eyes flashing orange as she slumped into his arms. He fell to his knees cradling her body to his chest as he sobbed. Dean looked at Cas but the angel was on the floor, tears in his eyes as he couldn't do anything to help her. He fell to his knees next to Sam and placed a hand on his shoulder and let out of sob of his own.
