Dean's Song Chapter 20 – Reversing the Spell

"You bastards…you will not win…he is mine do you hear me…mine!"

Dean watched in horror as the bed that Sam was attached to started to break apart. One of the wooden slats in the headboard broke free and sailed through the air towards Matthew. "Look out!" Dean yelled as he headed towards the man to push him out of the way.

"Dean NO!" yelled Missouri as she stepped in front of the young man. "Do not break his concentration…he must finish the spell…the Siren cannot reach us…watch!"

Dean stopped and watched in amazement as the wooden slat stopped at the edge of the salt circle and fell harmlessly to the floor. The crystals that they had placed were preventing the objects from passing through. "How?" Dean asked, looking at Missouri.

"These crystals absorb psychic energy…by the time the object reaches the boundary, the energy is lost. We will be safe as long as we stay outside the boundary." Missouri placed a calming hand on Dean's arm. She could sense his mounting concern…they may be safe…but what of Sam?

Sam's body continued to twist violently on the bed, even as another wooden slat came free and sailed harmlessly to the edge of the barrier. "He is already weakened by the poison within him…the poison given to him by his brother's own hand…I will possess this body and you cannot stop me!"

Missouri looked at Dean. "Poison…what is she talking about boy?"

Dean looked down at the floor, ashamed at the role he had played in harming his brother. "I guess while I was under her spell…she ah…well she convinced me that a potion was making Sam better…I didn't know…I would never…" Dean sank down next the wall, placing his head in his hands. He jumped when he felt a hand resting on his head.

"Boy, between you and your brother neither one of you have a lick of sense! This is not your fault…you did not fail your brother…but you should have told us about the poison."

"I didn't realize that it was still working on him…there was an antidote…I gave it to him and he seemed to get better…I guess it never occurred to me that it would take more than one dose!" Dean rose to his feet, looking at the figure of his brother; clenching his hands in frustration.

"Dean…listen to me closely, do you remember where you put the vials?" Missouri reached up and gently pulled on Dean's arm to get his attention. "Show me…I need to see if I can identify the poison and then copy the antidote so that we can give it to your brother once this is over…come with me Dean." Missouri watched as the emotions passed over Dean's face. She could see that he didn't want to leave his brother, but she needed him to help her. "That wasn't a request Dean Winchester…show me where the vials are now!"

Dean tore his eyes away from his brother and nodded as he followed Missouri from the room. He led her to the room where Sam had stayed and showed her where he had left the bottle of antidote. "I don't know where the vial is for the poison…I don't remember anything from when I was under her control…God this is so messed up!" Dean ran a shaky hand through his short hair, trying to remember.

Missouri reached over and touched his arm once more. "Dean, close your eyes and think of the vial…I may be able to break through the spell long enough to see where you left it."

Dean didn't like the idea of Missouri entering his head, but for Sam, he would march into hell…this at least would be less painful. Missouri closed her eyes for a brief moment and then snapping her fingers she looked at Dean. "Ok sugar…reach into your pocket for me and see if you don't find that vial!"

Dean reached into the pocket in his jeans and was surprised to find a small vial. Shaking his head, he looked gratefully at Missouri. "Do you think you can figure out the antidote?"

Missouri winked as she headed for the kitchen. "You get back to that brother of yours while I work on this problem…don't worry Dean, Sam will come through this just fine."

"How do you know…can you see into the future?" Dean asked, not quite sure how far her powers would extend.

"Boy…I told you once before, I'm not a magician…I just know that your brother has two things in his favor…first he's as pigheaded as that Daddy of yours and second…he's a Winchester through and through!" Missouri gave Dean a slap on the rump as she continued onto the kitchen

Dean hurried back to the room that contained his brother. Things were not looking much better. Matthew was still reciting the spell to release the binding curse and Sam was in the middle of what looked like a mini tornado of debris. Parts of the bed were flying around as Sam continued to struggle on the bed. Matthew finally reached the end of the spell. He calmly closed the book he had been reading from and looked at Dean.

"Ok, you need to be real careful here Dean…the spirit will do and say anything to save herself. Just remember, that no matter what your brother says or does, you have to stay outside the barrier…do you understand?" Matthew knew that the next step would be the hardest for both young men.

"I understand…Missouri explained it to me…just get on with it…we need to get to Sam before the poison in his system can finish its job!" Dean looked at Sam, who appeared to be resting quietly for the first time since this started. "Sammy…you fight it…Missouri is working on a cure for you and Matthew here is going to get rid of that bitch once and for all…you just fight it Sammy…I know you can do this." Dean looked away as his voice broke, he didn't want Sammy to see him upset. He had to stay strong for his younger brother.

Sam heard the words that Dean had spoken. He wanted to respond, to let Dean know that he would do his best…but he couldn't afford to use any energy…he needed everything he had to repel the angry spirit.

The Siren's appearance in Sam's mind had gotten dimmer for a period of time. But Sam knew that he still had a long way to go before this was over. Sam heard the murmur of Latin in a voice that was not familiar to him. Realizing that Matthew must have started the exorcism rite, Sam braced himself for what he knew would be coming.

"NO! I will not be defeated…I will use your powers against those you love…remember before Sam…I used your powers to hurt your brother. This time, I will use them to kill all those who are within my house!"

Sam could feel the pressure building in his mind and the pain once again also increased. "You are trapped here…neither one of us can break the barriers that have been place to contain us…you are finished, I will not allow you to take possession of me!"

"Why not let me in…I can give you what you seek…I can help you control your powers so that no one else will be harmed. How many more people must be hurt or killed before you give in? You are selfish Sam, only thinking of yourself."

"I won't listen to you…you are full of lies…soon you will be sent back to hell where you belong!" Sam watched as the Siren moved closer, her face a mask of anger and…yes, he could see it…there was fear in her eyes.

"Sam, you know that your brother would be better off without you…believe me, he will eventually tire of taking care of you, of trying to fend off your abilities when they decide to erupt…you saw the fear in his eyes…do you honestly believe that you will be able to stay with him?" The Siren continued to assault Sam, looking for the weakness that would allow her to surge in.

"My brother would never leave me…we have been through worse than this…Dean will always have my back. Besides, if I have to continue on alone, so be it…but it will be without you!" Sam groaned as the pain almost drove him mad…he wasn't sure how much longer he could continue to fight.

Sam felt the Siren gathering her strength, reaching into his mind to trigger his telemetric ability once more. He could feel her gaining a little more control as he turned to look at his brother.

Dean watched as Sam struggled to maintain control. He could tell by Sam's face, that this battle was taking a lot out of him. Suddenly, Sam opened his eyes and looked directly at Dean for the first time since they started.

"Dean…she's gone, Oh God…we did it! Please untie me…I need you Dean please!" Sam's eyes were filled with tears as he struggled weakly against the ropes that bound him.

Dean took a step towards his brother, unable to ignore the pleading tone in his brother's voice.
