A/N: Thanks to everyone who reviewed, I'm so glad you like the story! I have made a slight change to chapter two. The cousin Chris mentioned named 'Prue' is now called 'Mel'. There was a reason for this change, which you'll find out later in the story.

Chapter 4-

Zach and Chris' mouths dropped open.

"Wy?" Chris asked in confusion.

Wyatt just smirked. Piper smiled at her eldest son, and started walking over towards the ring of crystals, just as Chris suddenly came to his senses.

"Don't let him out!" Chris shouted.

"Why not?" Piper asked, confused.

"He's evil," Chris said.

Piper turned to him, her eyes flashing. "Don't you dare ever accuse my son of being evil again!" she said angrily. She turned to the ring of crystals and started pulling them away.

"Wyatt!" she said, opening her arms to hug her eldest son. He stepped away from her with a look of disgust.

"I'm afraid to say Christopher was right, Mother," he sneered. "For the first and last time in his life." He looked at Zach. "I'm very disappointed in you, Zachary. You turned away from me, your own brother. You'll go the same way as Christopher if you keep this up."

"Brother?" Leo repeated, but nobody seemed to hear him.

"Wyatt... you're not evil," Piper told him, more to convince herself than anyone else.

He laughed. "It's not about good and evil anymore, Mother. It's about power."

"And whoever has the most power wins," Chris muttered as though it was something he had heard many times before.

"Exactly," Wyatt replied triumphantly.

"That's ridiculous!" Phoebe replied. "It goes against everything the Halliwell name stands for."

"Yes, your daughter thought so too," Wyatt replied carelessly. "But she's not a problem anymore, is she?"

Phoebe paled considerably. "My... daughter?"

"Wyatt, you're my son," Leo pleaded. "This isn't you."

Wyatt's smile widened. "Isn't it?" He lifted a hand and watched in amusement as Piper, Paige, Phoebe, Leo, Chris and Zach were all thrown across the room. He laughed as they hit the wall.

"Well, I must be off," Wyatt said indifferently. "But before I go, here's a little something to remember me by." He threw a small glass vial at Chris. Before they could stop him, he was gone.

Chris groaned and his head fell back against the wall. Zach rushed to his side, and helped him to stand.

"Are you okay?" he asked.

Chris nodded.

Zach glared at them all. "Are you happy? Chris was telling the absolute truth and you slapped him across the face!"

Piper had a guilty look on her face. "I'm sorry, it was just so hard to believe..."

"I think I'm going to be sick," Chris said suddenly. He orbed downstairs with Zach. Leo glanced at the sisters, and then followed them.

Chris ran outside and threw up. He went back inside, wiping a hand across his mouth shakily.

"Was it the potion Wyatt threw at you?" Leo asked.

"What else would it be?" Chris replied angrily.

"Calm down," Zach replied. "We need to find out where Wyatt is. Well, little Wyatt and big Wyatt."

Leo looked at Zach and suddenly remembered what Wyatt had said in the attic. He gasped.

"What?" Zach asked, and then froze at the look in Leo's eyes. He could see pride, love... he had to know.

"You're my son, aren't you?" Leo whispered.

"Biologically speaking," Zach snapped. "And I'd appreciate it if you didn't tell anyone."

"You look just like Piper..." Leo said softly.

Chris sank into the couch, not having heard any of their conversation. Leo and Zach looked at him, concerned.

"I feel dizzy," Chris mumbled.

"This isn't good," Zach said, looking at Chris in worry.

Just then, Piper, Paige and Phoebe walked in. Piper looked pretty upset, but then again, she had just found out her son was evil.

"What's wrong with Chris?" Paige asked, seeing him slumped on the couch.

"Whatever Wyatt threw at him is making him sick," Zach replied. "Chris, are you awake?"

He didn't answer. A mirror shattered, making them all jump. Leo, Paige and Phoebe all looked at Piper.

"Hey, it wasn't me this time," she defended herself.

"Sorry, my bad," Zach muttered.

"You can blow things up?" Piper asked, seemingly excited.

Zach shrugged. "Looks that way, doesn't it?" he replied cryptically.

"So, um, if you can tell us... just exactly how bad is Wyatt in the future?" Phoebe asked.

"He's the evil overlord of the entire world," Zach replied.

Leo, Paige and Phoebe all gasped, which Zach thought only happened in movies and crappy novels. Piper looked like she was about to cry.

"You must be lying," Piper said feebly.

"Well, he's not," Leo snapped. "So let's all face it."

Phoebe and Paige eyed him suspiciously.

"Why are you on his side all of a sudden?" Paige asked.

"Why not?" he replied.

"Guys, I hate to break up this little meeting, but Chris is dying," Zach told them, bringing them all back to earth. "Once Wyatt decides to kill someone, they're as good as dead. Unless of course, we find an antidote for the potion."

"I'll check the book," Paige, Piper and Phoebe all said simultaneously.

"I'll stay here with Chris," Zach said, looking at his brother sadly.

Phoebe felt his pain, and a wave of pity washed over her. She put a hand on his shoulder.

"We won't let him die," she told him quietly.

He nodded, and watched them go upstairs.

"He'll be okay," Leo told him.

Zach said nothing.

"Why do you and Chris hate me so much?" Leo asked him.

Zach stiffened. "We don't exactly hate you."

"You seem to," Leo said, watching the boy closely.

"Okay, we hate you," Zach snapped. "Happy now?"

The pained look on Leo's face was almost enough to soften Zach. Then he thought of the way he had treated Chris his entire life, and his face hardened again.

"Why do you hate me?" Leo asked softly.

Zach ignored him, instead turning his gaze to his sleeping brother, wondering if he would ever wake up.

"Phoebe, Paige, I'm so scared... what if I don't get my son back?" Piper asked.

Phoebe shrugged. She had been in her own little world since the visit from Wyatt... she had a daughter! But the way Wyatt had spoken of her made it sound like he had done something... something bad.

"It'll be okay," Paige soothed. She shot Phoebe a look. "Right, Phoebe?"

"Oh, yeah, right," Phoebe replied vaguely.

Paige gave her a sympathetic look. "I'm sure your daughter will turn out fine."

"Daughter?" Piper repeated, her head snapping up.

Phoebe nodded. "Wyatt mentioned her."

"This is pointless!" Paige muttered, tapping her fingers impatiently on the book. "I can't seem to find anything we can grasp on to. There are lots of entries about potions, but they're all pretty much the same. How are we supposed to find an antidote to all these different poisons at once?"

"We'll figure it out," Phoebe said, though she wasn't feeling very sure. She knew it was selfish, but the main reason she wanted to have Chris well again was so that she could pummel information about her daughter from him and Zach.

"I told you trying to heal him wouldn't work, Leo," a very irritable Zach said.

"It didn't mean I couldn't try," Leo said. "And that's Dad to you."

"Whatever, Leo," Zach muttered. It was hard just sitting there watching his brother, the only person he had left in the world, just lie there, slowly dying.

Chris' eyes opened slightly.

"See! I told you it was worth a try!" Leo said triumphantly, but Zach ignored him.

"Are you okay, Chris?" Zach asked fervently.

"Oh yeah, I've got a deadly poison running through me and I'm just peachy," Chris replied sarcastically, his voice somewhat weak.

"Do you know what the poison was?" Zach asked.

Chris shrugged slightly, and then winced. "Wyatt uses a lot of poisons. I can't remember every single one of them."

"Can you sit up?" Zach asked. "How does the potion make you feel?"

"I'm fine," Chris replied, trying to sit up. Zach put an arm around him and he managed to pull himself up. Chris groaned.

"What's wrong?" Leo asked, worried.

Chris looked at him, seeming to notice he was there for the first time.

"Wow Leo," Chris replied cynically. "For a second there, it almost sounded like you cared about me."

"My son obviously cares about you, therefore so do I," Leo replied curtly.

Chris' eyes widened slightly. "You told him?" he asked Zach.

"Wyatt gave it away," Zach said.

Chris nodded slightly. "It's strange... I can't really remember what happened in the attic."

"This potion seems pretty dangerous..." Zach said uneasily.

"With these conditions, I think Chris only has about three days to live unless find an antidote," Leo said heavily. "I can't heal him, only drain his pain and lessen the illness slightly."

"You can't die..." Zach answered unhappily.

Chris gave a tiny smile. "If worst comes to worst, you're here now. You can save the future." His eyes closed, and they could see his eyes flicker shut. He was sleeping again.

"He's not going to die," Leo said vehemently. "I don't know what I did in the future to make you hate me so much, but I'm sure as hell going to make up for it now."

"I might actually believe that if you didn't always break your promises," Zach said sorrowfully.

"I'm not that person yet, Zach," Leo replied. "I won't let Chris die. We're going to save him, okay?"

And Zach almost believed him.

"We need Wyatt's blood," Leo announced.

They all blinked. "Huh?"

"What have you been doing for the last day?" Leo demanded. "I've been to seven demon lairs, the fairy gardens and a parallel universe and I've finally found out the antidote. Wyatt's blood and a spell should be enough to save Chris."

"Isn't going to a parallel universe a little... extreme, Leo?" Paige asked hesitantly.

"I found out the antidote, didn't I?" he replied patronizingly.

Phoebe blinked again. "He has a point."

Zach was staring at his father though. He couldn't believe that for once in his life, he had done something for Chris and he hadn't even been awake to see it. Then again, it was more precisely because of Zach that Leo had found out the antidote, and that was how it always was. Leo only ever did something for Chris if Wyatt, Piper or Zach really wanted him to. Never just for Chris.

"How are we supposed to get Wyatt's blood?" Paige asked. "Just exactly how powerful is he, anyway?"

Zach shrugged. "He's the most powerful person in the world. He can pretty much do anything."

"Well, that's just great," Paige muttered. "How the hell are we supposed to summon him if he'll instantly kill us afterwards?"

"He won't kill us," Piper said confidently. "We saw him before and he didn't."

"He would kill us," Zach told Piper seriously. "I'm not sure why he didn't kill us all before, but you have to trust me. Wyatt would not hesitate to kill us."

"How do you know?" Piper asked.

Zach looked at the ground.

"Oh my god," Phoebe gasped softly, looking at him. She could feel his grief. "He killed us in the future, didn't he?"

Zach didn't reply.

"We need to get to work," Leo said, looking at Zach with slight concern. "Otherwise Chris will die."

"It's almost midnight Leo," Piper told him. "We barely slept last night, and we need to have plenty of rest. What is demons attack and we're too tired to fight? Chris has been unconscious the entire time, but you said it yourself, he has two days left."

"No!" Zach said stubbornly. "We can't rest knowing he could be about to die!"

Leo sighed. "Zach, get some rest. I guess Piper's right. You didn't sleep at all last night. I'll watch Chris."

Zach nodded glumly and plonked himself in an armchair. In less than a minute, he was fast asleep.

"Why do you care about him so much now, anyway?" Paige asked Leo, who was watching Zach with a fond expression on his face.

Leo shrugged. "I just do," he said simply.

A/N: Yeah, I know it was a lame place to end it; I just wanted to get the chapter up. Please review!
