Chapter one

a/n: Here's the next chapter. Slight crossover with charmed, nothing really. Mention of Mpreg.


"What!?" Giles exploded, rising from his seat with a very ripperish look. "Who the hell do you people think you are?"

"Like we said." Sineya answered, sighing. "We're from the future. I know it's a little hard to believe, but..."

"A little hard? A little!" Giles snapped. "How did you think I'd react to you telling me someone I think of as a son is going to be 'the' ultimate evil!?"

"How do you think we feel!?" Sineya yelled back. "We grew up with him. We watched him kill all those people. He used us to..."

"Sin." Jesse sighed, cutting her off. "Dawn told us to tell you something that only you know."

"And that would be?" Giles asked, still skeptical.

"We can show you." Jesse answered, standing up and moving toward him. "If you let us."

"How?" Giles asked. "I don't understand."

"Just trust us a little, ok?" Sineya said, getting up and standing beside them.

Giles watched cautiously as Jesse place his hand over his heart and Sineya laid her hand on the side of his head, both closing their eyes.

"Close your eyes." Sineya instructed, voice echoing as she and Jesse opened their pure white eyes.

Giles closed his eyes. Seeing images of the final fight with Glory. Him killing Ben. Buffy sacrificing herself. Willow and Xander bringing her back.

//That was then.// Jesse's voice echoed through his mind. //Now. This is our future.//

Images of Xander on a throne made of bones. Long dark hair and black eyes. Younger versions of Jesse and Sineya dressed like slaves, chained to either side of Xander's throne. Demons everywhere. Then the sun being blotted out. Numerous people dying at Xander's hand.

"Enough." Giles said gruffly, pulling away from them. "I... uh..." He trailed off images flashing through his mind. "I believe you. What do you want me to do?"

"Do you know a Sam Winchester?" Sineya asked.

"Y-yes, I do. He and his brother showed up about two months ago." Giles answered. "Why?"

"We need to speak to him, to everyone." Sineya answered. "We need help, we can't do this alone."

"I'll call the others." Giles said, walking away.

"Do you think he'll be there?" Jesse asked Sineya nervously.

"I don't know." She answered, turning to him. "Even if he is, he's not the same person we know. You have to remember that."

"Alright." Giles said, walking back into the living room. "We're all to meet at Buffy's house in a half an hour."


"Giles, what is this about?" Buffy asked, sitting next to Dawn keeping an eye on the two newcomers.

Xander, Sam and Dean were sitting on the couch, Willow and Tara in the love seat and Spike standing off to the side.

Giles looked to the twins.

They looked around nervously, eyes finally landing on Sam and Xander. Thoughts of a future neither of them wanted to return to.

"We're from the future..."

"Really?" Xander asked excitedly, cutting Sineya off. "How far?"

Sineya eyed him, trying to reconcile the image of her father in her mind and this man sitting in front of her.

"Twenty five years." Jesse answered quietly, trying not to look at Xander. "My name is Jesse. This is my twin sister Sineya."

"We came back to save our dad." Sineya added. "And to stop our father from becoming the greatest evil and plunging the world into darkness."

"Ok." Xander said confused. "Who's you're father?"

Jesse made his way over to Sam. "You're my dad."

"And you're my father." Sineya said to Xander.

"Wait, didn't you say you were twins?" Xander asked and when she nodded continued. "Then that... wait... Sam.. who... how?"

Jesse laughed, feeling a little more comfortable around this man who was and wasn't his father.

"In the next year or so you'll find a way to have us." Jesse answered, chuckling. "Obviously it's a magical way."

"Which one of us is evil?" Sam asked nervously, aware that the Demon had plans for him.

The twins both silently turned to Xander.

"What? Me?" Xander yelled, standing up. "No way!"

The twins lowered their eyes and backed away.

Xander realized that they were afraid of him and trying to be submissive. It made him sick.

"Hey." He said softly. "I'm sorry I didn't mean to yell. I'm not going to hurt you." He tried to sound reassuring, holding his hands up as he sat back down. "It's a little hard to grasp, you know? Me. Being ultimate evil. I mean, how?"

"You made a deal with the first to save dad." Jesse answered softly, looking at Sam.

"Okay wait." Buffy said, cutting in. "Why don't you start at the beginning. And tell me why the hell you're setting of my spidey senses."

Sineya looked around the room, eyes finally landing on Buffy. "I'm a Slayer." She finished softly. "The last Slayer."

"And I'm a witch." Jesse added. "And we're both seers."

"And we're your parents?" Xander asked, dumbfounded by his powerful children. "How did that happen?"

"Well you are 'The One Who See's'." Sineya answered. "And dad has visions. It's no wonder we're seers."

Jesse's eyes started to turn white and his voice echoes through the room. "I don't know how much we should tell you. It started right before father lost his eye. When the first was here...


"Xan are you sure you should be doing this?" Sam asked worriedly. "I mean, come on, patrolling while you're pregnant."

"No I'm not sure, but I can't stay in that house any longer." Xander answered, frustrated. "I mean two months cooped up in that house with the girls. That's enough to drive the sanest person crazy. "

"I know." Sam sighed. "I just don't want anything to happen to you or our baby."

"I know." Xander replied. "Our baby. Isn't that crazy?" He asked with a goofy smile. He stopped and wrapped his arms around Sam. "Did I tell you how much I love you lately?"

"No." Sam pouted, with a wicked twinkle in his eyes. "Why don't you show me."

Xander grinned and captured his lips with his own.

"Still not feeling the love dude." Sam said, smirking when Xander pulled away.

Xander growled and attacked Sam's lips with a fervor, then trailing kisses across his face and neck.

"Well look what we've got here." A voice said, interrupting them.

Xander and Sam broke apart, looking around. There was nothing there.

"Who's out there?" Sam called out, scanning the shadows.

"Forget about me already, Sammy boy?" The Demon asked, stepping out of the darkness.

"You!" Sam snarled, pulling Xander behind him.

"Yes me." The Demon answered.

Waving his hand, sending Sam flying into a tree and pinning him there.

"Sam!" Xander yelled, running towards him.

"Uh-uh." The Demon tsked, pinning Xander to the side of a mausoleum. "Me and your boyfriend need to have a little chat."

"Let him go, you son of a bitch!" Sam yelled, trying to break free.

"Sammy, Sammy." The Demon taunted, approaching him. "I needed you strong. Honing your skills. And what do I find? You settling down on the Hellmouth and knocking someone up."

"Shut! Up!" Sam snarled.

"Whatever are we going to do?" The Demon asked teasingly, ignoring his outburst. "I could kill him." He said looking over his shoulder at Xander. "Like I did to your mom and Jess."

"No my..."

"Yes, your baby too." The Demon replied, cutting him off.

Oh God, no. Sam thought, looking over the Demons shoulder at Xander who was struggling to break free.

"Or you can come with me, be my soldier." The Demon added.

"What makes you think I won't kill you once I'm free?" Sam asked hotly.

"And what makes you think I won't just kill you and take your baby." The Demon snarled in his ear.

Xander watched as Sam started to scream, bloody gashes appearing all over his body.

"No!" He yelled. "Stop!"

"Oh just wait." The Demon said looking at him, smiling. "It gets better."

Sam gurgled as blood seeped from his mouth, trails running out of his eyes and nose.

Oh god please Xander thought, as he watched horrified. Stop this.

"Well, I'm not exactly God but," The First said, appearing in front of Xander as his long dead friend Jesse. "Close enough."

"What do you want?" Xander asked warily.

"Oh, it's not what I want." The First/Jesse answered, smirking. "It's what you want from me."

"Can you help him?" Xander asked desperately.

"I can." He answered. "For a price."

"Anything." Xander replied breathlessly. "I'll do anything. Just save him."

"I'll give you six months with him." The First answered. "Six months then you come to me willingly. Agreed."

"What?" Xander asked in disbelief. "Are you nuts."

"You better come to a decision soon." The First said, looking towards Sam and the Demon. "Wouldn't want to bring your boyfriend back as a zombie would you?"

"Alright!" Xander yelled. "I agree. Save him!"

Xander looked over when the Demon screamed, his body covered in flames. Sam standing there unharmed, watching in horror.

"What happened?" Sam asked, making his way to Xander.

"I don't know." Xander answered wearily. "i don't know."


6 months later

Xander was laying in his bed thinking about the past month.

They had defeated the First and his army of Turok-han. Sunnydale was now a crater. Slayers were activated all over the world. The others had gone off to rebuild the council and recruit the new slayers.

Sam, Dean and him had opted to stay in L.A. to try and have a normal life and to be a family.

Dean was in the living room watching TV and Sam was in the shower.

"Hey there Little One." Xander said, rubbing a hand over his pregnant belly. "One more month and you'll finally be here."

"Hello Alexander." The First/Jesse said, stepping out of the shadows.

"What are you doing here?" Xander asked, afraid. "We beat you."

The First laughed. "Did you really think you could defeat me?" It asked approaching Xander. "I'm the original evil. I was always here and I always will be."

"What do you want." Xander asked warily.

"Don't tell me you forgot about our deal." The First answered. "Sam's life in exchange for you."

"I remember." Xander replied. "What if I don't go with you?"

"Then your little boyfriend drops dead." The First answered.

"What do you want me to do?" Xander asked, defeated.

"I want to give you a piece of me." The First said in a low voice. "To give you power beyond your wildest dreams. For you to be strong. For you to be my tool on earth. Do you accept?"

Xander's eyes dart to the bathroom. "Can I say goodbye?" When the First shook it's head, he snapped out. "Just do it then!"

The First laughed maniacally, it's body changing into black smoke. The smoke whirled around Xander, seeping into his pores, suffocating him. Xander closed his eyes and tried to fight it. No, I can't do this. I won't. He thought as the smoke disappeared. He could feel it. A massive darkness within him. Running through his veins. Something ancient. He felt powerful. More alive than ever before. He opened his midnight black eyes, smirking.

//I need you to do something for me.// The Firsts voice echoed in his mind.

"Yes?" Xander asked, getting off the bed.

//Three witches and their children.// The First answered, as an athame appeared on the bed. "Kill them and you'll be stronger."

"How do I find them?" Xander asked, picking up the athame.

Images of a red house, a San Francisco sign, three woman and two children flashed through his mind.

"It will be done." Xander's voice echoed as his body erupted into flames.

"Xan?" Sam called out, walking into the room. "You in here?"


"Father went and killed these witches." Sineya added. "All except one. Their son Chris, he got away. He's the one who helped us to come back."

"I think that's how I got my powers." Jesse said as his eyes faded back to normal. "I can stop time and blow things up. One of the sisters had the same powers."

"Oh god." Xander said, getting up. Putting a hand over his mouth, his voice came out muffled. "I think I'm going to be sick." He ran to the bathroom.

"Jess." Sineya called out as he went to follow their father.

"It's alright." He reassured her as he left the room.

"There's more isn't there?" Sam asked sadly.

"Unfortunately, a lot more." She answered gravely.


"Hey." Jesse said as Xander walked out of the bathroom. "Are you alright?"

"You're asking if I'm alright after all the things you went through." Xander answered with haunted eyes. "I killed those people."

"No." Jesse replied. "You haven't. Not yet. We can stop any of this from ever happening."

Jesse managed not to flinch when Xander grabbed onto his arm.

"Did I..." Xander trailed off, taking a deep breath. "Did I ever hurt you guys?"

Jesse looked into his glassy eyes, seeing pain and turmoil.

"Not physically." He answered, thinking it wasn't much of an assurance. "We should get back."

When they got back Sineya twined her fingers with her brothers.

"You said you have the power to stop time?" Giles asked. "Can you show us how it works please?"

Jesse looked around the room, feeling slightly nervous. He never liked being the center of attention. He picked up a glass bowl off the coffee table an tossed it into the air. Raising his arms, he flexed his hands. The bowl shattered. He flexed his hands again, the shards stopping right above the table.

"Wow!" Dawn exclaimed. "That was so cool."

"Yeah, it's pretty cool." Jesse replied softly. "I just wish a witch didn't have to die for me to have it."

"It's getting late. Buffy you will patrol." Giles said, scowling at Buffy when she rolled her eyes. "Do you two have a place to stay" He asked the twins.

"No." They answered together.

"You can stay with us." Xander offered quietly.

The twins eyed him warily.

"Aw come on." Sam cut in when he saw their look. "He isn't evil yet. Not that he's ever going to be." He quickly added. "You can't just pop in from the future and tell us you're our children and think that we won't want to get to know you."

The twins looked between their parents then to each other, eyes having a silent conversation.

"Alright." Sineya answered, looking at her parents. "We'll go."
