"Why won't you just die!?" He bellowed pulling the Colt from his jacket. He fired a single shot and Clark moved to stop the bullet. It passed right through his hand and sank into his heart.

"Clark!" Sam looked to his left spotting Chloe vacating her car and racing to his side. Clark looked at her with a shocked expression on his face and then his body flashed two times before he collapsed to the muddy ground; completely dead. Chloe rushed to his side and pulled him up and checked his pulse; nothing. "Clark! You can't die! It's not possible!"

"Why are you grieving over him? He tried to kill you, remember?" Sam asked her while placing The Colt back into his jacket pocket.

"Because, he's not the one that tried to kill me," Chloe said with tears in her eyes.

"What are you talking about?"

"He has a doppelganger; someone who looks exactly like him, but is completely different on the inside."

"There's no way that guy could have been a shape shifter. They're nowhere near that strong," Sam thought as he looked at Clark's dead body. But as he continued to think he remembered how Clark didn't make the first move during the fight. He didn't even seem to recognize Sam and you tend to remember someone that just beat the shit out of you as Dean would put it. That would mean he just killed an innocent person. The realization went through Sam like a knife had gone through his heart and he sank to his knees. He let his demon blood control him and now he made a mistake he couldn't undo. The blackness of his eyes faded back and he buried his face in his hands.

"No time to beat yourself up, 'agent'," Chloe said breaking out of his shock. "You and Clark can still stop that thing."

"Excuse me? He's kind of dead."

"Not for long," Chloe said pulling Clark closer to her and placing a hand on his forehead. "I hope this works," she prayed and then a bright and beautiful light encircled both of them. A yell escaped Chloe's lips as the light increased. When it died out Clark's eyes opened and he took in several breaths followed by a few coughs.

"Chloe? What happened?"

"You were dead, but I brought you back," she explained sounding a little out of breath.

"You used your powers? Chloe, don't you remember how dangerous they are to use?" He asked in concern observing how some of the color from her skinned had drained out.

"Relax Clark. I'm still breathing aren't I?" She said with a weak smile. Clark returned her smile and then looked to his left to see Sam looking at them both very surprised.

"Who are you?" He said in a defensive tone not forgetting the fight they just had.

"He's here to help. He saved my life from Bizarro earlier tonight."

"Bizarro? But that's impossible. He died."

"Says the man whose come back to life twice," Chloe then rested her head on Clark's shoulder.

"Chloe! Are you ok?" He asked getting worried.

"I just need to rest. I used enough of my power to bring you back, but had to stop before you were fully healed. So like it or not you're handicapped and are going to have to bring that guy with you to take on Bizarro," and then she passed out in Clark's arms. He super sped her into the house, laid her on the couch to rest, and super sped out to face Sam.

"So you want to tell me what you are?" He asked.

"You want to tell me what YOU are?" Sam replied with the same question.

"Fair enough."

"I'm Sam Winchester," he said extending his hand.

"Clark Kent," he replied shaking Sam's hand.

"Ok now that the introductions are out of the way, I know where we can find your little double. He hangs out at a place called Club Atlantis under the alias of Kal."

"Figures," Clark thought. "All right. Hang on."

"To what?" Sam asked confused as Clark put a hand on his shoulder. The next thing Sam knew he was in Metropolis. "How did you…" Sam's stopped mid sentence and threw up in the street.

"That usually doesn't happen," Clark said fighting back to repress a grin. Sam rolled his eyes and the two of them walked to the front of the line.

"Kal? I thought you were already in there?" A confused doorman said. "And when did you change your clothes, man?"

"Someone threw up on them and I had to exit the back way to go change," he said smirking at Sam. Sam ignored the comment as the doorman let Clark through. As he walked to the door the doorman held up his hand to stop him.

"Where do you think you're going?" He asked.

"Inside obviously."

"Kal gave me strict orders not to let someone who matches your description to let you inside and this time I can't be bought."

"Fine by me," Sam said and knocked the doorman out with a single punch. Sam stepped over his unconscious figure and was followed by everyone else in line.

"What took you so long?" Clark asked him as Sam took a seat at the bar.

"Doorman was being a dick. Any sign of your evil twin?"

"Working on it." Clark activated his super hearing and tried to zero in on Bizarro's voice.

"Naught aren't you?" He heard Bizarro laugh followed by the excited laughter of another girl. Clark left his seat and entered the dance floor; zeroing in on the sound of Bizarro's laughter. Sam was trailing behind him as the mob of dancers made it hard to keep up.

"Why don't we ditch this club and head back to my place?" Bizarro asked squeezing her ass.

"Why don't you leave this girl alone?" Clark asked. Bizarro shoved the girl away from him hearing Clark's voice and turned to face him and Sam. "Boy Scout; was wondering if we'd ever meet again. And look, you brought a little back-up," he said gesturing towards Sam.

"You're going back to the sunny side of Mars where you belong," Clark said.

"Why don't we continue this conversation somewhere a bit more private?" Bizarro asked and sped them all out of the Club; the partygoers too drunk or having too much fun to notice.

Bizarro reached the top of the Luthor Corporation building and tossed Sam and Clark near the edge.

"So would you like to know how I survived?" Bizarro asked as Sam and Clark pushed themselves off of the floor. Not bothering to wait for them to answer, Bizarro continued. "It was a freak chance of luck when Lana discarded my remains in a dumpster. She just happened to lay them near a chunk of Kryptonite. During a freak storm a bolt struck the Kryptonite, which charged my remains enough for me to reform my body."

"Sounds like something that would conveniently happen in a comic book," Sam commented. Bizarro glared at Sam and started walking towards him. Clark rushed in front of Bizarro to stop him, but received a punch in his chest sending him flying off the Luthor corp. building and crashing in some other part of the city.

"One down," Bizarro said. Sam's eyes turned black as Bizarro advanced at him and telekinetically threw him over the edge of the building. Bizarro flew back to the top and flew full blast at Sam carrying him off the building and into the sky. The city was quickly left in the background while they flew towards Crater Lake. Bizarro let go of Sam and let him crash land into the dirt. Sam felt the wind get knocked out of him as he pulled himself out from the massive pile of Earth he was now in.

"What the hell are you?" Bizarro asked speeding to his position. "No human could withstand that impact."

"Well I'm not your average human," Sam replied and delivered a blow to Bizarro's stomach. He stumbled back and Sam tackled him into a tree. Bizarro swung his fist missing Sam's head by inches and unearthing the tree he hit in the process. He seized Sam's jacket collar and hurled him into the lake. As Sam attempted to surface Bizarro dived in and pushed Sam further down to drown him. Sam struggled to drive Bizarro's hands from his neck. Putting all his power into one punch he uppercut Bizarro stunning them both when Bizarro went soaring out of the lake and crashing to the earth below. Sam resurfaced coughing out water; he looked and saw Bizarro charge him, but before he could attack Clark sped into the fight and knocked Bizarro backwards into a tree. He picked up the fallen tree and swung it at Clark like a bat; the tree shattered and splintered upon contact driving Clark back into a rock, which also broke on contact. Bizarro hurled the remainder of the tree at Clark, but it stopped in mid-air. Clark and Bizarro turned to see Sam stretching out his hands toward the tree. He used his powers and sent the tree crashing back into Bizarro.

He slid through the dirt and recovered breathing heavily slightly. Clark sped behind him and kicked him in the back sending him into Sam's fist to his face. As Bizarro fell towards Clark, he dodged his next attack and kicked his feet out from under him. He followed up upper cutting Clark into the sky and then flew upwards to punch Clark right in his neck. Clark felt the world fade in and out as he shot towards the Earth, but managed to regain his composure to dodge Bizarro's next attack. Tired of toying with Clark, Bizarro rushed him and launched them both into the air. Bizarro changed directions and shot back down to the ground at an incredible speed. Sam spotted the two getting closer and dove in the water to dodge the shockwaves of the crash. The result collision over turned every tree within a few mile radius and even affected the lake; Sam was thrown about as the water shook from the impact taking in a mouthful of water. He swam rapidly to the surface and spit out the water as he popped his head out of the water. He swam to shore and gazed in awe and terror at the humongous crater formed from where the two of them landed. One of them pushed the other off him and ascended the weakly. Sam stepped back as he reached the edge and rolled out; to hurt to move as he laid spread eagled on the ground.

"Wonder what the press is going to say when they discover this mess," Clark laughed lightly.

"What happened?" Sam asked shaking a little from the fight that just transpired.

"I took control of the descent at the final moment. He took the brunt of it."

"Do you think he's dead?"

"If I survived then he more than likely did as well."

"What are you going to do with him?"

"I have a friend that can take him some place where he'll never harm anyone ever again."

"I am not going back to Mars!" Bizarro thought hearing Clark's comment and sprung out of the crater. He shoved Sam away and stood over Clark. "Bye-bye Boy Scout!" He yelled and moved to finish Clark off. He suddenly froze mid attack and gripped his chest. He saw Sam walking towards him; teeth clenched and eyes jet black. Bizarro groaned in deep pain as he felt an invisible force clutching his heart. Sam closed his fist and Bizarro's heart was crushed killing him instantly. Sam felt himself turn back to normal and looked at his two shaking hands.

"What's happening to me?"

One week later

After Bizarro had been killed, salted, and burned, Sam remained in Smallville to help Clark repair some of the damage to the barn. The two of them became pretty good friends as the days went by. Sam even helped Clark out with a few meteor freaks. There was still the pressing matter of the unfixable damage done to Crater Lake, which literally had its own crater now. That fact did not escape the ever watchful eye of a certain intrepid reporter.

"I am telling you Clark. There's no way in hell that crater was from a meteor. Did you see the way it was formed? That meteor would've had to have shot straight down to Earth at a 180 degree angle and let's not forget how there wasn't even a meteor on radar according to NASA. I' m going to get to the bottom of this if it kills me Smallville," Lois finished.

"Knowing her it very well might get her killed," Clark said to Sam and Chloe, who both laughed.

"What was that, Clark?" Lois asked putting her hands on her hips.

"Nothing! Nothing," He said putting up his hands in surrender. Lois rolled her eyes then walked over to Clark to give him a hug. "I'll see you around Smallville. Nice meeting you, Sam. Chloe." she said hugging her cousin and exiting the Kent household.

"Nice girl," Sam said as she left.

"And a handful," Clark laughed.

"Where are you headed now Sam?" Chloe asked as he headed over to the Impala.

"My brother's a few cities down. I'm going to pick him up from the hospital and then we will be on our way. Maybe I'll see you guys again someday." He then switched on the ignition and drove off into the sunset.

Met. Gen.

"Has he talked to anybody since being admitted?"

"Not a soul. That is to be expected when living through a traumatic experience. He was rambling on about the strangest things when he was being piled into the ambulance," the doctor replied.

"Is it alright if I speak to him?"

"Be my guest." The woman smiled and entered the hospital room of Agent Henrickson.

"Hello Henrickson. Do you know who I am?" He looked in her direction and shook his head no. "My name is Tess. Tess Mercer."

"Lex's right hand woman? What would you want with someone like me?" He asked speaking for the first time since he arrived here.

"I want to know what really happened at the police station."

"I've already told people what went on down there and they didn't believe me. How do I know you are going to be any different?"

Tess smiled and said, "Try me."

On the Road

"So how was the hunt Sammy?" Dean inquired.

"I met this guy named Clark Kent. He was some sort of super human. I made the mistake of killing him when it was some sort of duplicate that had committed the murders in Smallville. He was brought back to life by his friend Chloe but her power took a lot out of her."

Dean was shocked to find out that Chloe possessed powers of her own, but he couldn't act like he had previously known her. As Sam fell asleep in the Impala Dean began to think about everything that had happened to him in Smallville.

"Sammy," Dean thought. "I wish I could tell you about everything that happened back then. How I did things I'm not proud of. But the less you know the better."

Meanwhile in another city in the United States a young girl was running for her life. She ran into an alley way and hid behind a trash can.

"I think she went this way," one of her pursuers said. They walked past her hiding spot and she breathed a sigh of relief. She crawled away from her hiding place, but knocked over the garbage can as she got up.

"There she is!" One of them spotted her.

"Oh shit!" She cursed and made a break for a nearby warehouse. The two men following after her. She ran down the hallway not turning around. She could hear their loud footsteps as they chased her. She tripped and fell to the floor. The two men walked over to her with rather sadistic smiles on their faces.

"How's the dead man's blood bitch?" One asked pulling out a machete from his jacket. The vampire tried to crawl away, but the other hunter rammed his foot into her ribs stopping her.

"No. Please don't," she begged as the hunter grabbed her jacket and pushed the blade into her neck. He raised his blade, but someone appeared from behind him. The mysterious arrival grabbed the hunter's blade and shoved it into his heart. He deflected the other hunter's attack and broke his neck.

"It's ok, Kate," The man said helping her to her feet.

"Wait a minute," Kate said. "I know you. You're Spike," She recognized. "But aren't you… didn't you… die?" She asked confused.

"You shouldn't believe everything you hear Kate," He said leading her out of the warehouse.

"Where are you taking me?"

"You will find out momentarily." Kate was puzzled. She was almost certain that Spike died. They exited the city and continued on into the outskirts. Kate's eyes widened at what she saw next. "As you can see Kate, Vampires aren't as close to extinction as you might have thought," he told her as she looked on at the large number of Vampires.
