Chris' first memory of the Underworld was when he was about six years old and had been kidnapped by a band of angry demons.

He didn't remember much about the experience except for Piper being really pissed, blowing them all up and then letting him have some extra ice cream for dessert. Chris soaked up the sisters' sympathy for all of ten minutes until he accidentally turned Wyatt's hair purple.

Personally, Chris had always thought it looked better that colour.

Since that first experience Chris had spent a great deal of time down in the Underworld, either killing demons or being kidnapped by them. He much preferred the former.

And the former was the reason that Chris was stood in the middle of a cavernous room, blood red stalactites nearly reaching the floor as they wove around ornate pillars that did nothing except make the cave seem a little classier than a hole in the ground.

Of course any classiness was completely undone by the four steaming piles of black robes dotted around the room.

The remaining demon was cowering against a pillar, his horns shaking, as he watched Chris advance towards him. If Chris had left him his arms he would have been holding them up in surrender.

"I'm going to ask you again, slowly," Chris raised a hand and the demon felt a familiar burning pain begin in his foot. "Where is Pertinax?"

The demon stared up at him, not saying a word. Chris twisted his hand and the burning began to move up his leg. "Okay, okay!" Yelled the demon and Chris froze in surprise. The deep, Australian accent wasn't exactly what he'd been expecting. "Look, mate, I think I know the bloke you're looking for."

"Erm," Chris stared at him wide-eyed for a moment, forgetting his role as the terrifying interrogator, "So you know where he is, right?"

"Well, I might be able to think better if I still I had my rooting arms!"

"Oh," Chris looked sheepish and waved his hands slightly, causing one of the demon's arms to reappear. He looked slightly happy for a moment and then a shackle appeared from the air and looped around his arm, pinning it to the column.

"What, I don't even get 'em both back?"

Chris crossed his arms. "You're still a demon. And I still want answers."

The demon shook his head. "Look, you bloody idiot, Pertinax gets around," Chris gestured for him to continue and flicked his wrist so the demon felt the little finger of his newly restored hand fall off. "But," said the demon, sighing, "I'm thinking he might have gone a walkabout up round the northern lava pools. You know where I mean?"

"By that demon bar?"

"We prefer to be called 'evil beings', you know," Chris tapped his foot in impatience, "yeah, it's up there."

Chris smiled at the demon. "Thanks."

"You're welcome," the demon, trying to twist his grotesque face into a semblance of a smile, "and you're gonna give me me arms back, right?"

Chris shrugged, "Fine." He flicked his hand at the demon as he orbed away.

The demon smiled happily as his arms reappeared, to be replaced quickly with a frown as heavy metal chains bound him to the pillar. "Oh, you bloody whacka. Just rack off, then!"

When Chris had turned eighteen, Wyatt had deemed him old enough to drink. When Chris had looked at him disbelievingly, Wyatt had shrugged and said that short of orbing to England the best he could do was take his little brother to a local demon bar and get him plastered whilst blowing up some of the more uncouth customers.

Chris didn't remember much of the experience, twelve demon infused tequila slammers will do that to a guy, but he was fairly certain that the bar he was stood in front of was the bar that Wyatt had taken him. Was going to take him. Whatever. Chris hated tenses.

He glanced around, rubbing the back of his head. Wyatt sensing him was turning into a full blown yell that was sure to cause him a migraine if he wasn't careful. Of course, he could just talk to his big brother but Chris knew that all Wyatt would be full of was some sane, sensible advice. And Chris wasn't really in the mood for sane, sensible advice.

Because his mother's killer was stood right in front of him.

A cold, hard hate settled through Chris, a primitive side of his brain doing nothing but calling for revenge. He clenched and unclenched his fists at his side and he felt his jaw do the same as he angrily eyed the demon in front of him.

Apparently Pertinax had just been going for an afternoon drink when Chris had surprised him, evidenced by the buxom blonde who was clinging to his arm. The tall demon looked him up and down, his long leather jacket swirling in the heat from the lava behind him. He laughed, showing off three rows of pointed, yellow teeth.

"Hey, babe, why don't you go get us a table?" Pertinax whispered down the blonde, his hand tightening on her shoulder as he saw the way she was appreciatively eyeing Chris.

"Sure," she said, her breathy voice more suited to a Marilyn Monroe-esque model than a demonic blonde, whose slanted green eyes winked at Chris as she sashayed by, not missing the opportunity to run a hand down his chest. He tail swung tantalisingly round one of his legs before she purred in frustration and walked into the bar.

Chris didn't even notice her go, his entire attention was fixed on the demon in front of him, remembering the way that his clawed hands fastened around his mother's throat.

"Look, little boy," Pertinax said politely, dusting his hands down his coat, "You may have noticed that I'm a little busy," he gestured at the bar, "so can we just get this over with?"

Chris growled himself and when he spoke he was almost surprised at himself, his voice was that low and cold. "You have no idea how easily I could kill you."

Pertinax began to look slightly annoyed, "Look, little boy, I. Do. Not. Have time for this. And I don't like to play with those I don't need to kill."

"Did you need to kill my mother?" Chris yelled before he could stop himself.

Pertinax laughed then, a sound like nails running across a chalkboard. "Ah, so this is a revenge thing, then?" He clapped his hands together. "Let me guess, your mother was a witch who got in my way and now you're here to avenge her death, yadda, yadda, yadda." His eyes narrowed to slits. "Well, I don't have time for that." With an animalistic growl he leapt forward.

With barely a flick of wrist Chris sent him flying behind him. Pertinax sailed through the air, twisting so that he landed on his feet. He ran forward to Chris' now exposed back and Chris just smiled grimly picking him up in a telekinetic hold and spinning him so that he was facing Chris.

Tightening his grip around his throat so that Pertinax began to choke, his hands scrambling uselessly at his own neck. Chris focused and Pertinax's hands flew to the sides, impaled in the air by non-existent nails. Hanging there, choking to death, Pertinax began to kick his legs uselessly.

"You see," Chris said conversationally, "there was a problem with your little scenario. Because my mother wasn't just a normal witch. She was a Charmed One."

Pertinax's eyes widened from more than just being choked to death.

Chris laughed. "Oh, I know what you're thinking. None of the Charmed One's have adult children. But, you see, I'm from the future. And now you are never going to have the chance to kill her." All humour vanished from his voice. "Because I'm going to kill you first."

With a thud Pertinax dropped from the air. As he caught his breath he looked up and grinned evilly at Chris, flexing his talons as he began to stand. And then a new expression crossed his face.

Chris tilted his head and watched him, his eyes blank. "Want to know what you're feeling?" Pertinax's eyes began to bulge out of his head. "That's me. Crushing your heart." A strangled scream erupted from the demon's throat and Chris laughed. "That was my thumb. Being stuck into your heart."

Pertinax fell to the ground, his mouth open in a scream.

Kneeling Chris watched him, as though to ensure he was really dead. "And that was me killing you."
