Rebecca stared at the man – no, demon, she reminded herself – standing before her. He stood near her cage, arms clasped primly behind his back. His thick black hair, more salt and pepper in the light of the Underworld, was wavy and tousled, as if he had been running his hands through it. His eyes were so dark, they looked black from the distance. His eyes were almond shaped – like Rebecca's – with long, thick lashes no man should posses. His grin was easy and relaxed, like he knew he held all the power at the moment, and he relished in it.

And yet, his dark, fathomless eyes looked lonely, possibly sad.

They looked, Rebecca realized, startled, like hers.

"It's a shock, I know," Carsaeus said with a small shrug. "A demon for a father... Unthinkable, hm?"

Rebecca narrowed her eyes and shrugged. "I've seen it before."

"Ah, yes," Carsaeus said silkily. "Your cousin, Katelyn Halliwell." His eyes sparkled with mischief.

"Would you spare me the dumb lectures and stupid revelations?" Rebecca demanded.

Carsaeus chuckled. "You are so like your mother," he remarked, tilting his head, as if taking her in, like a curious cat trying to scout his prey.

Rebecca gritted her teeth and said nothing. He wanted to bait her, she knew that, and she refused to fall for it.

"Paige was always very... stubborn," he remarked. "She despised games, like you... Clearly." He sounded amused, and she hated him for it.

After a moment of hesitation, Rebecca moved to the back of the cage, crossing her arms before sitting.

Carsaeus quirked a brow at her.

"Well, if you're going to keep yapping, I'm going to sit back and relax," Rebecca said with a shrug. "If you like the sound of your voice as much as you seem to, then this could take awhile."

Carsaeus blinked in surprise before breaking out into roaring laughter. "Clever little girl. You do so sound much like your mother." His laughter fell off into a chuckle before he stopped altogether. "The most amusing thing about your mother?"

Rebecca looked away, feigning disinterest. Although, deep down, she was dying to hear what he had to say.

"She didn't realize," he continued, a devilish smirk on his face, "that she was getting in to bed with a demon."

...

"The good news is, Rebecca is still alive, and will likely remain that way for the time being," Karen said, looking from Corrine to Melinda, and finally to Katelyn.

"How do you know?" Melinda demanded.

Karen frowned, not wanting to break the news to them. "I just do."

"That's not good enough," Corrine snapped. "He's a demon. He was able to strip us of whatever makes us the Power of Four... How do you know he won't kill her to prevent us from regaining that power?"

"Because..." Karen hesitated. "That's my bad news... The demon is Carsaeus. He is... Well, he's Rebecca's father."

"What?" Corrine demanded.

"But that's not possible," Melinda argued. "Aunt Paige always told Rebecca her father was human."

"And that was the truth," Karen said with a nod. "Paige always believed he was human; he acted human, behaved human... He fooled her. Keep in mind, she didn't know that she was a witch when she met him. So she wouldn't have known to look for any demonic signs."

Katelyn's heart pounded at this new information. On the one hand, she felt excitement and joy at the idea that she wasn't alone; being half-demon had always plagued her, especially since Corrine and Melinda were witch and witch/Whitelighter. They didn't understand her struggles, or how hard it was, day-in and day-out, to fight her demonic nature.

But Rebecca would understand now.

Except, at the same time, her heart ached for Rebecca. Because she knew how hard it was to fight a demonic nature. And she knew that, for the rest of her life, Rebecca would face the same struggle. Being a Halliwell Witch didn't change that; if anything, being a powerful witch made the struggle harder. The more power, the higher the risk of going power hungry.

"So..." Corrine said, when the silence became unbearable. "He won't kill her... Because she's his daughter?"

"Well," Karen said, "He's still a demon. And it's in his nature to kill a witch. However, I do think he'll try first to convince her to become evil. Only when that fails will he try to kill her."

"Okay, good," Melinda nodded. When they all looked at her like she was crazy, she quickly added, "Well, it means we have time. We can work on potions and spells and figure out how to get Rebecca out of there before he hurts her."

"We can try," Corrine argued. "But he's powerful, Mel. He's strong and he's evil and he's been planning this since before any of us was born. He knew he was bedding a future Charmed One. He has knowledge that I'm pretty sure even the Source didn't have."

Melinda nodded. "Right. I know. But, even without the Power of Four, we're still Halliwell Witches. We're still the daughters of the Charmed Ones. We have magic coursing through our veins. That doesn't change just because our magical bond has been severed. We're still witches, and she's still family. We have to rescue her."

"What if we're too late already?" Katelyn asked softly; so softly, her cousins barely heard her. When they finally registered what she had said, they looked at her in confusion. "What if he's already turned her? Or... killed her?"

"Rebecca's stronger than that," Corrine said, shaking her head. "No way she gave in that easily."

"She's strong," Rebecca agreed. "But her demonic nature? It might be stronger..."

Neither Corrine nor Melinda knew what to say to that.

...

"Haven't you wondered why your Whitelighter powers don't often work the way you want them to?"

Rebecca glanced up sharply at Carsaeus. She had been resolutely starring at the ground, running her fingers through the dirt and ignoring everything he said – even the things she found intriguing, the things she truly wanted to know more about. So far, she had refused to fall prey to his smooth talking.

But this... After twenty minutes of ignoring him successfully, this caught her attention and she couldn't help herself.

He grinned. "I knew that would get a response."

She scowled, hating herself for satisfying him like that.

But then she frowned in thought; she had always wondered why her powers never seemed to work for her, why she could never get the hang of orbing or healing. She still wondered, especially, how she had brought Corrine back from the dead. It was possible her demonic nature had allowed her to do so, and she shuddered at the thought.

"Your demonic nature wars with your witch and Whitelighter natures," Carsaeus continued. "Until you fully embrace each of her magical inheritances, none will ever work properly for you."

Her eyes widened at his words, before she quickly forced her face back into a neutral expression, refusing to let him see her thoughts.

But it was too late, and he grinned at her. "You see where I'm going with this, correct, little witch? You have already embraced your witch and Whitelighter heritages. Now, you must fully and completely embrace your demonic nature."
