When Excalibur had been taken away from Wyatt, it was decided the best way of keeping it safe was to hide it in plain sight. The decision was made to put it on display at Magic School with a three-step security system to protect it.

The first was a key that Paige kept at all times, which operated a magical force field. The second was a spell that caused anyone who touched Excalibur to turn to stone. The counter spell had been locked away "up there" by the Elders.

The third was a more conventional type of security with a fifteen-digit code, which gave access to magical unbreakable glass that had been especially conjured to surround the Magical Sword.

Wyatt had obviously been able to steal the key from Paige, and according to the Elders had also managed to procure the counter spell. The numerical code was the final obstacle, and that was what he was using all his powers of concentration and limited psychic powers to work out as his family orbed in trying to prevent him doing just that. Wyatt didn't even turn to look at them. He was so close to achieving his goal, and so confident that his family would not attack him, he kept his concentration where it was needed.

Suddenly Wyatt opened his eyes and smiled as the final number of the code came to him.

"You're too late!" he said to his family as they started to walk toward him.

He punched the final number into the keypad as Piper shouted "Wyatt! No!"

Wyatt completely ignored his mother's plea, as he watched the glass casing around Excalibur drop. He quickly recited the spell to prevent him turning to stone, and then took a deep breath, relishing the fact that he, and he alone, had overcome the three security measures to hold Excalibur.

Wyatt could feel the power start to overtake him as he reached out his hand to finally take command of Excalibur and, in his mind, fulfil his destiny.

His moment of glory was thwarted however, as Chris, seeing what was about to happen, called out for Excalibur. Hearing the cry of its true Master, Excalibur immediately flew across the room into Chris's hand.

Wyatt had now reached breaking point, and not showing any concern for the safety of his brother or the rest of his family, immediately threw fireballs in their direction.

They all frantically ducked for cover, except Chris who skilfully used Excalibur to deflect the fireballs.

"Since when was Wyatt able to throw fireballs?" Piper asked Leo, aghast, as they both cowered behind a sofa.

"Since when did Chris learn to use Excalibur?" Leo asked back, surprised.

"What are we going to do, Leo, I can't attack my own son?" Piper asked, hoping he would have some logical response. She looked over at Phoebe and Paige who were taking cover behind an upturned table, also seemingly not knowing whether to attack him or not.

"We've got to stop him somehow," Leo replied to Piper or he'll kill Chris. As Leo finished that sentence they all saw Chris go flying across the room as Wyatt used his telekinetic powers to fling him there. Unfortunately, Chris lost his grip on Excalibur in the process. The magical sword fell to the floor in front of Chris who was lying very still after falling heavily.

"I don't need you!" Wyatt shouted to Chris, now so obsessed, that nothing else mattered. "And I will make sure you never have Excalibur again!"

He formed a fireball in his hand and was about to throw when both Piper and Leo screamed, "No!" at him. Piper running to protect Chris, Leo directing a lightening bolt towards the now air born fireball.

The two energy forces collided above Excalibur sending a concentrated explosion down towards the Magical Sword.

Wyatt watched in horror as his precious Sword exploded into hundreds of small pieces of deadly shrapnel, which catapulted around the room at lightening speed. Leo quickly orbed out as several pieces headed in his direction, hitting the table behind him that was still protecting Paige and Phoebe.

Chris had no time to react, as he was still recovering from his heavy fall and had no idea what was happening.

Piper had been standing in front of her son ready to blow up the fireball heading in his direction, when Leo had beaten her to it. The next thing she knew, the force of the explosion threw her back, falling on Chris, protecting him in the process from the lethal metallic fallout. She, however, was not so lucky.

Leo orbed back in and immediately saw Piper lying on Chris with blood seeping from wounds in her chest and stomach.

"Piper!" he shouted as he ran to her.

Chris, now recovered, moved out from under her, still oblivious as to what had just happened. Then he saw her wounds, "Mum!" was all he was able to say before Leo was next to him, trying desperately to heal her. He looked up and saw Paige and Phoebe were watching anxiously also. "What the hell happened?" Chris asked looking at all the debris around him.
"Excalibur was hit by a fireball, I think, and just exploded sending bits everywhere," Phoebe tried to explain to him.

"And Mum was hit," he said stating the obvious. "God, Dad, she looks bad, there's so much blood, you can heal her, can't you?"

"I'm trying, Chris" was all Leo would say.

Chris looked over at Wyatt, who was down on the floor trying to pick up the tiny pieces of Excalibur, devastated. He didn't even appear to have noticed his mother, seriously injured on the other side of the room. As Chris was watching him, Wyatt started to compose himself and then suddenly stood up and began reciting a spell, his hands outstretched. A few seconds later a book materialised in front of him and Chris recognised it immediately as a time travel book that had been kept hidden at Magic School. He didn't even know that Wyatt knew about the book, let alone a spell to summon it.

Suddenly he realised what Wyatt was going to do. Chris looked to Leo, who was still busy trying to heal the multiple wounds suffered by Piper. "Dad, I think Wyatt is going to try to go back in time," he said to him frantically as he looked from his Dad, to his Mum and then to his brother.

Leo, unfortunately, was using all his energy to keep up the healing process on Piper, and didn't even hear what Chris had said.

Chris looked back at Wyatt, who had found what he was looking for in the book and was reciting the spell. Suddenly a triquetra still drawn on the far wall, started to glow.

"Dad, look! Wyatt is going to go back in time to get Excalibur – we've got to stop him!" Chris said as he started to get up.

Everyone's attention was diverted to the glowing triquetra and Wyatt running toward it.

Before anyone else had time to even register what was happening, Chris was on his feet, running after him, tackling him to the floor just before Wyatt made it to the glowing time portal. Their relief at seeing Chris stop Wyatt before he was able to enter was short lived however, because a few seconds later, they watched helplessly as the two of them still fighting each other rolled through the portal just before it closed.

The last thing Chris heard was his father screaming his name before he was engulfed by the familiar eerie silence of time travel.
