It was a cold day in San Francisco. The streets were calm and peaceful but it wasn't quite the same in the Halliwell manor.

"Wyatt! Stop it!" said Piper.

Baby Chris ran out of the room, crying, followed by Wyatt who definitely didn't obey Piper. At the same moment, Paige was passing by and grabbed Chris in her arms, slowly swaying him to make him stop crying. Piper followed closely, exhausted.

"Thanks Paige! Without Leo, I can't be everywhere and watch out for the guys at the same time." She turned around to face Wyatt. "Mommy told you not to bother Chris, sweetie. He is only 1 and a half years old. He's younger than you are. Take it easy with him, okay?"

Without waiting for an answer, she looked back at Paige holding Chris and smiled, amused. "You know, I would see you with kids…"

"Me? Are you kidding?" she answered.

"Absolutely not! I'm sure you would be a great mother!"

"Yeah, but who would be the father?" Paige asked as she rubbed Chris' cheek to rip off the tears.

Piper shrugged and said "Oh, I don't know. Henry maybe." Paige made an exhausted face. "What?" continued her sister. "Don't you like him?"

"Yeah, I mean... no… I… I don't know" Paige said with a sigh. "It just seems so complicated."

Piper smiled and nodded slowly. "Story of my life" she commented with a playful wink. "Come on" she said and went downstairs, followed by her sister and Chris.

Meanwhile, Billie was in the basement with Phoebe, practicing her martial arts' skills. Phoebe was in a defensive position waiting for Billie to attack.

"Come on, don't be shy!" she told her with a hint of mockery.

Billie ran on her and started punching and kicking. Phoebe stopped her attacks and levitated briefly and went over her opponent's head to land right behind her. She lightly kicked her in the back and Billie fell on the floor, face first. She managed to stop the shock with her arms and pushed herself back up into a sitting position. She turned around, facing Phoebe and narrowed her eyes at her.

"That's not fair! You used your powers!"

"Oh, because you think demons won't use their powers against you?" She paused and smiled thoughtfully. "It's funny, you're just like me when I used to practice with Cole…"

Billie laughed briefly and stood up, preparing to attack again. Before she could do anything, a big noise came from the kitchen. They both looked at each other quickly and ran upstairs.

Arrived in the kitchen, they saw Paige and Piper unconscious on the floor.

"What the hell happened?" Phoebe exclaimed. She approached her sisters and bent down beside them, taking their pulse and making sure they were still alive. At the same moment, another loud sound came from upstairs. Billie and Phoebe ran to see what it was, climbing the stairs as fast as they could. When they arrived, there wasn't any sound anymore. They looked in each room, ready to come face to face with a demon but found nothing.

"I'll go check the attic" said Billie.

"Alright, I'll look here again. If you find anything, tell me" Phoebe said before walking off into her own room.

Billie reached the attic door, surprised to see it closed. She gently opened it and looked by the slit. A tall skin man was talking to Wyatt, who haven't put his shield up. The demon had curly dark-blond hair and he was wearing a black long coat with brown ornaments and had obviously black pants as well.

"Do you think you could give me this big book Wyatt?" he asked in a soft voice, designating the Book of Shadows. Billie noticed the man was also holding Chris' hand.

She quickly went to take Phoebe and they both got back to the attic door and looked at the scene in awe.

"We should stop him before Wyatt takes the Book" Phoebe whispered. At Billie's nod, they both entered the room, pushing the door fiercely.

"What do you think you're doing?" asked Billie.

The man smiled and looked at them. "Look at this, the Charmed Ones needed a back up" he mocked, seeing Billie.

Phoebe made a step forward but he pointed at Wyatt, who was now holding the Book of Shadows. She stopped her motion and asked angrily: "What do you want from us?"

The man looked amused. "I don't need to answer that, I already have what I need! Thanks to Wyatt over here." He paused and Phoebe's sighed stopped on both the boys starring back at them with a confused facial expression. She resisted the urge to run and kick the demon's ass but she didn't have time t do anything before he spoke again. "See you in… the future." Then, he disappeared in flames with Wyatt and Chris.
