Chapter 2-

"Why did you come back, Zach?" Chris asked, when they were safely on top of the Bridge.

"In our time, you've been gone almost a year," Zach replied, looking at Chris. "I wasn't sure what had happened to you. I just wanted to check you were okay... you're my brother."

"How did you escape from Wyatt, though?" Chris asked. "If it had been easy enough for you to escape, I would've taken you with me. Well, if it wasn't for Cia and Myra."

"Chris, Cia and Myra..." Zach choked out. "Wyatt killed them."

Chris could feel the blood drain from his face. "How?" he whispered.

Zach shook his head miserably. "When we found out about him killing Bianca, we were furious. We killed some of his guards, and I guess it was just the last straw. We've been killing his assassins for over a year now. He just tied them to stakes, and set them on fire in front of all the prisoners. I don't know why he didn't kill me. Maybe he couldn't because of our bond. I don't think so, though, because he tried to kill me as I was escaping through the time portal."

Chris wrapped his arms around his dismal younger brother. It wasn't fair that Zach had to see all this when he was so young. He was barely an adult, yet he had seen the dead piled up in the streets, the hungry people killing each other in squabbles for food scraps, the children being tortured in revenge over things their parents may not even have done. And he had seen his brother murder his own cousins in cold blood.

So, Wyatt had killed his youngest cousins, just like their other cousin Mel. But why had he not killed Zach?

"Ugh, they've been gone for hours!" Piper said in frustration. Her hands twitched, and Phoebe and Paige winced as a vase shattered. Leo had long since returned to the rest of the Elders, so they were forced to endure Piper's bad mood alone.

Phoebe and Paige were not as angry though, since they both trusted Zach, even if they didn't trust Chris. For Paige, this was because of the job she used to have as a social worker. Zach reminded her of the teenagers she would see on the street, with their despairing, haunted eyes. Phoebe trusted him, because she had felt his sadness, and his love for the sisters and Chris. She didn't know why he loved them, and wondered who they were to him in the future. She did know, however, that this love could only mean that he wasn't against them.

"Finally!" Piper muttered. Chris and Zach had orbed back into the house. Zach looked like he had been crying, but none of them commented on it, since Chris was glaring at them all.

"We want some answers," Paige announced.

Piper and Phoebe nodded in agreement.

"Okay, it might help if we knew the questions," Chris replied sarcastically.

"Um, why did you come back in time, Zach?" Phoebe asked.

"To help save Wyatt," he replied.

"Well, why didn't you come with Chris?" Piper asked.

"It was safer this way, in case I failed, Zach could come after me," Chris said expressionlessly.

The Charmed Ones all nodded. Suddenly, Leo orbed in.

"There's been a great shift of power," he told them breathlessly. "We don't know if it's good or bad. The Elders have told me to come down and ask you if you knew anything."

All eyes shifted to Zach.

"I don't have much power," he admitted. "It wouldn't have been me."

"It must have been," Leo said, looking at Zach suspiciously. "What powers do you have?"

Zach looked at Chris helplessly.

"Future consequences," Chris said sharply, looking at Leo. "I'll go and check the Book."

He walked off, pulling on Zach's arm. Zach followed Chris, after looking longingly at Piper. Chris knew Zach must have been finding it hard to be with her after seeing her dead, but he also knew that neither of them could get used too used to it, or they would be ripped apart if they went back to the future and had to lose her again.

"Who is he anyway?" Leo asked the Charmed Ones. It was obvious whom they were talking about.

"His name's Zach," Piper said. "Apparently he's a friend of Chris'. From the future."

"You should probably keep an eye on him then," Leo said frowning.

"No," Phoebe said sharply. "He trusts us. He loves Chris, and I know he cares about us too."

Piper raised an eyebrow. "I thought Chris and Bianca were-"

"Not like that," Phoebe said rolling her eyes. "But it seems they're pretty close friends."

"But if he's friends with Chris," Leo replied.

"Look, I know you don't trust Chris, Leo," Paige said. "But his friend seems okay. I agree with Phoebe."

"Wyatt's life is at risk here!" Piper exclaimed. "We can't leave his life in the hands of two people we know next to nothing about."

Phoebe and Paige remained silent. They knew that it was no use arguing with Piper when she was in this mood. And they knew that Leo would do anything to protect his son.

Meanwhile, Chris and Zach were looking at the Book upstairs.

"I missed it," Zach said softly, running his hands over the front of it.

"Do you have any idea how stupid that sounds?" Chris asked him, with a tiny smile on his face. "But I know what you mean. I hate the idea of it in Wyatt's hands."

"Chris, our bond with Wyatt..." Zach started. "Could you feel his anger?"

Chris nodded. "You too?"

"Yeah," Zach replied. "I'm not sure why we don't have the telepathic link anymore. I mean I know that he tried to break it, and succeeded only in weakening it, but why can we feel each other's emotions and no words?"

Chris shrugged. "Maybe emotions are stronger than words."

Chris flicked through a few pages in the Book, while Zach stared out the window.

"It's so different," Zach said finally, breaking his gaze from outside. "To see people walking around outside, happy. Nobody starving, or killing..."

"We won't go back to that, Zach," Chris said. "I promise."

Zach nodded. He found it hard to believe, but Chris never broke his promises. Not to him.

"Oh god," Chris muttered, staring down at the Book.

Zach walked over to him, and saw that the Book was open to the page on time travelling.

"What?" Zach asked.

"The shift in power," Chris muttered. "You said that Wyatt knew you were escaping and tried to kill you as you went through the portal."

"You think he sent assassins through it to try and kill me?" Zach asked, his sea-green eyes wide in terror.

Chris shook his head.

"I think Wyatt came through the portal to try and kill you," Chris said grimly.
