When Reality Bites

Chapter 15 – Final Battle

Dean rushed over to Sam, breathing a sigh of relief when he felt a pulse. He gathered Sam up and put him back onto the bed. Next, he helped Missouri get Theresa into the other bed. "What's going on?" Dean asked Missouri

"Well, the demon is now trapped in Sam's mind. But for some reason, Sam hasn't been able to finish the banishing spell…if he doesn't do it soon, I'm afraid both of them will be lost!"

ooooooooo

Sam shook his head as he saw another Theresa walk into the room. The demon/Theresa looked astonished and flinched as it heard the name "Cristo" come from the young girl's lips.

Sam smiled as he realized that the real Theresa had found a way to join him. "Hi Theresa, I'm glad you're here" Sam said sincerely. "Now I know where the demon is hiding and we can banish him!"

The demon/Theresa snarled and began to transform in front of both of them. The demon now had the form of a young boy with soft brown eyes and light brown hair. He appeared to be about 16 years old. He turned towards Theresa with pleading eyes.

"No…you are not real!" Theresa shouted as she started to back away.

"You could have stopped this…you could have stopped the pain of so many and yet, you refused, you waste your powers!"

Sam saw Theresa shudder as the demon hit close to home. "Theresa, fight it…he wants…" Sam felt himself shoved up against the wall, an invisible force was closing slowly around his throat. He couldn't breathe…the pressure continued to increase as Sam felt himself losing consciousness.

"Speaking of useless powers, you could have easily kept me from your mind, yet your fear has made you impotent! But now, I can feed on both of you…your powers combined will make me…Argh…No!…how can this be!" The boy/demon's face writhed in agony for a few moments only to turn to Sam and glare at him with pure hatred in his eyes.

"Sam…Missouri and your brother have banished his physical presence…we have to banish him before he can take hold…Sam!" Theresa dropped to her knees as she felt an excruciating pain in her middle. It felt as if she was being ripped apart from the inside out. Tears welled up in her eyes "Sam…please…you have to fight…you have to…" Theresa fell to the floor and wasn't moving.

The pressure on Sam's throat had lessened, but not enough for him to speak. He looked at Theresa feeling frustrated and useless. Once again he was suppose to have all this power and when he needed it most…nothing! The demon was right…he was useless!

The boy/demon grinned as he felt the torment from Sam. "I will give you a choice boy…if you will surrender to me, let me possess your body…then I will let the girl go!"

Theresa moaned as she slowly raised her head, meeting Sam's gaze with a fierce determination. "Don't listen to him Sam…I can leave any time I want to and he knows it! He can only control you Sam…you must fight him!" Once again Theresa groaned as the pain began again. She wasn't sure how much longer she would be able to maintain the connection.

Sam watched as Theresa struggled. He felt the anger building as he thought about the number of people that had suffered because of this demon. He would not give in…no matter what it cost him!

ooooooooo

Dean watched helplessly as his brother and Theresa both writhed on the bed. Missouri was silent as she watched their torment. "Can't you do something!" Dean pleaded

"Boy, I told you I can't work miracles…and I am doing something…I'm waiting for the right moment…so stop distracting me! We're only goin' to get one shot at this!"

Missouri took one of Theresa's hands and gently touched her forehead. "Hang in there Theresa…just a little longer!"

Dean watched as Theresa quieted under Missouri's touch. Sam on the other hand seemed to be gasping for air as his body continued to thrash on the bed. Dean sat on the bed and gathered his baby brother into his arms, trying to keep him from hurting himself. "Sammy…come on bro'…I know you can beat this bastard…you beat the other's who have tried…just fight Sam…I'll be here when you come back!"

ooooooooo

Sam felt a calmness come over him…it was almost as if he could feel a new strength entering him. Sam looked at the boy/demon, matching the hatred he saw in the demon's eyes with hatred of his own. Theresa was slowly getting to her feet, but remained silent…almost as if she was listening to someone.

Sam felt the demon's strength weakening as the pressure on his throat decreased. He pushed back using his mind against the force holding him against the wall. The effort was painful…Sam felt as though his head was going to explode, but he didn't give in…he wasn't sure why, but knew he had to keep the boy/demon concentrating on him.

"Too little too late! As soon as you lose consciousness, you will be mine boy!" The boy/demon approached Sam, grabbing him once again by the throat, choking the life from him.

"NO!" Sam croaked as the boy/demon was flung across the room. Sam stumbled as he fell to the floor. Ignoring the pain in his head, Sam stood on unsteady legs and approached the boy/demon. He tried to speak the banishing spell, but couldn't seem to get the words past his injured throat.

"Hah…you can't banish me if you can't speak! I knew of your pathetic plan to get rid of me. Granted, I didn't realize that you're brother and the witch were planning to get rid of my corporeal self…but it works out better this way. I can possess you and feed off you at the same time!"

Sam shook his head as he continued to concentrate on keeping the boy/demon away from him and Theresa. Suddenly out of the corner of his eye, he saw Theresa begin to move next to him, a glazed look in her eyes. "Sam…it's time, you have to hold him…whatever you do, don't let him go!"

Sam reached over and held onto the boy/demon with all of his strength. Wrapping his arms around the beast, he struggled to hold him down as Theresa began chanting the banishment spell.

The boy/demon screamed in rage…objects started flying around the room, hitting Sam, but being deflected from Theresa. The pain in Sam's head intensified to the point where he felt like he was going to be sick. But still he held on…he wasn't going to let this bastard get away. Sam could feel the cuts and bruises he had received from the flying objects…he could feel himself weakening. "Hurry" Sam croaked at Theresa as he reached into his final reserve of strength.

"You won't win…I won't let you…It's imposs…argh!" The boy/demon burst into flames right in front of Sam. Sam hurriedly backed away, fearing that he would be burned by the flames. He turned to Theresa and before he blacked out croaked "Thanks!"

ooooooooo

Theresa gasped as she became conscious of Missouri and Dean in the room around her. Her body ached in places that she never knew existed and she felt totally drained. She was grateful when Missouri gently held a bottle of water to her mouth, helping her to drink. "Now you just rest a moment child…you've done a great job!"

Dean kept stroking Sam's forehead, willing his brother to open his eyes. He looked over at Missouri, his anguish clearly written on his face. "Why hasn't Sam woken up?"

"I'm not sure honey, but if I know that brother of yours, he is just pig headed enough to find his way back…it may just take him a little time."

"Sammy…you have to wake up little brother…damn it, you promised you would come back!" Dean sighed as he got ready for an even longer night.

Raven524: So…the demon is gone…but Sammy, well I guess we will just have to see (evil chuckle). Hope you all like where this has gone so far…remember to R&R…otherwise you may never know Sam's true fate!
