Paige sat at her desk talking to her uncle on the phone. She had thought that she might be related to the Halliwell family but after what she had witnessed the night before she seriously hoped she was wrong. She was typing the name of the church she had been left in as a child into mapquest so she could talk to the nun who had found her and hopefully find some clues as to who she was and why she had been given up. What Paige didn't expect was a visit from a young, handsome brunette who claimed to be FBI. Sam had walked up to the cubicle and introduced himself with one of his many aliases. He could tell that Paige was a bit suspicious when she narrowed her eyes and gave him a look over.

"What exactly is it that you want from me," Paige asked him.

"The FBI is investigating the death of Dr. Griffiths at 1329 Prescott street. We've taken over the investigation from the SFPD and I was told from the detective that interviewed you about your attack last night that you knew the Halliwell sisters. The attacks seemed to have the same MO and you even look the last victim; one Prue Halliwell. How do you know the sisters?"

"I didn't," Paige said. "I never told the detective that I did. Shane, my date," Paige explained, "had the wrong idea."

"Oh," Sam said. "How exactly did he get the wrong idea," he questioned.

Letting out a sigh, she began to explain. "I, at one time, thought that I might be related to the Halliwell sisters because I was adopted but..."

"But something scared you, didn't it? If you know anything about what the Halliwells are into then you need to tell me so I can help you. Two people have already died, and you and your boyfriend have already been attacked. The killer might come back for you. Are you prepared for that?"

"He's not coming back for me," Paige told him. " I mean, he doesn't know who we are. It was random," she tried to cover up.

Sam got up and took a card out of his pocket. "If you need anything give this number a call. I'm handy with strange cases," he said and left. Paige looked at the card and threw it in her purse before she got up and left.

Sam turned his engine on and followed the green buggy as he talked to Dean on his cell phone. "Yeah, she just left. I don't know how much she knows about what's going on but I don't think she's as involved as the police believe. Hold on a second, she just pulled up to the church. Hey, what are the sisters doing here," he asked his brother who was supposed to be watching Piper and Phoebe back at the manor. Sam jumped at the tap on his window and rolled it down to see Dean.

"I followed them here and Bobby is doing a little B & E on the manor. He's going to try and get a look at their book and snoop around a little before they get back."

"What if the nun tells Paige that her private investigator has already been there?"

"Well, we're going to have to tell them the truth at some point if we want their help. Hey, whose that guy," Dean said pointing to a man with dark hair.

"That's Shane, the victim of the second attack," Sam told his brother. "Look at the gargoyles; I thought it was only myth that they cam alive to ward off evil," he muttered when the man fell to the floor.

The doors to the church were thrown open and Paige rushed to his side.

"Paige, no!" The two sisters were thrown back by an invisible force and the Winchester brothers dived into action, running into the church after the sisters.

"What the hell was that," Dean yelled at them.

"That's what I'd like to know," Sister Agnes said surprising everyone.

"Who are you exactly," Leo asked the two men his wife and sister-in law had brought home.

"Dean and Sam Winchester," Phoebe answered for them. "They're hunters."

"I've heard of your kind," Cole said. "Kind of stupid of you, going after things more powerful than you. You must be good if you managed to stay alive this long. Hunter's have a short life expectancy."

"Yeah, well we've had good teachers and lots of field experience."

"Was the guy we found in our crystal cage one of your teachers," Piper asked with a smirk on her face. When the sisters had returned to the manor they had hurried to the attic to find Bobby trapped, in the cage.

"Yeah," Sam said holding back a laugh. "He's like our own personal roadside scholar on all things supernatural."

"Well, clearly not all things if he didn't even recognize a crystal cage," Piper said grinning. "He'd still be cussing if I hadn't given him a home cooked meal."

"Piper's guide to men," Phoebe chuckled, "fill their mouths with food so they can't get a word in edgewise."

"Yeah, well it gave us time to fill Dean and Sam in about the Source," Piper replied.

"So the Source was there, at the church," Leo asked, still wary of the two strangers in their midst.

"Well, the gargoyles weren't exactly whistling Dixie," Dean piped up.

Piper gave their visitor a glare before speaking. "Plus, something pretty powerful knocked us on our asses."

"But if he was there, why didn't he try to kill Paige," Cole demanded.

"Maybe he didn't want to go up against the Charmed Ones," Phoebe told her boyfriend.

"No, that doesn't make sense. He knows that Paige is new to her powers. If ever there was a time to attack…"

"Wait a minute," Leo interrupted Cole. "What if he's not trying to kill her anymore? What if he's trying to lure her to his side?"

"Translation please," Sam spoke up. He shot his brother a look, knowing how hard Dean was restraining himself from wasting the demon that stood across from them, and even harder to stand in the midst of witches, especially since they hadn't told the Halliwells about how they had stumbled across them.

"The mythological window," Cole told them.

Leo explained further. "There's a window of opportunity, an opening."

"48 hours," Cole said.

"Right, 48 hours where a nascent witch who hasn't chosen to use her powers for good or evil yet can be swayed either way," Leo said, sitting down.

Phoebe looked horrified. "Wait, so all he has to do is cast a spell on her?"

Cole shook his head. "No, he can't. It has to be her choice, but he can tempt her, entice her. If he gets her to use her powers for evil…"

"She becomes evil forever," Leo finished.

"Who makes up these cockamamie rules," Dean demanded and watched as the two men look toward their respective domains. "Oh, never mind…"

"Okay, so we have less than 24 hours to get to Paige and no idea how to find her," Phoebe said chiming in. The past couple of hours had been interesting to say the least since they had met the Winchester brothers, and all Phoebe could hope was that they could save Paige. She had already lost one sister.

The two groups drove up to South Bay Social Services and moved into action when they saw Paige with her hand held out; a mysterious aura surrounding her. Dean went back with the sisters to try and save Paige, while Sam and Cole separated to search out the Source. Sam had gone one way, hoping that his demon blood would allow him to sense the Source's presence like Cole claimed he could.

Night had fallen when he got a call from Dean, asking if Cole was near him. "No, why? What's going on?"

"We're on our way back to Paige's building. The sisters just faced off with the Source and he said something about killing Cole. We'll be there soon."

"Alright, I'll try to find him," Sam said and hung up. He retraced his steps back to the building and headed in the direction that he last saw Cole. When he arrived there he found Cole lying off to the side, hidden next to the bushes.

"Hey," he called out. Sam checked Cole's pulse and was relieved to find it although it was weak. He began to perform CPR, pumping against Cole's chest until the gang arrived.

"Cole," Phoebe shouted and ran to him, kneeling next to him and leaning over Sam who was still doing chest compressions. "Oh no. No, no, no, no, no, no, no, no, no, no, no, no," she whimpered, pulling his head up into her lap.

"Heal him," Piper commanded Leo.

"You know that it's against the rules".

Phoebe turned to her brother-in law and looked at him through her tears. "Leo, screw the rules. The Elders owe us."

"Even if I could, I could only heal his human half and that… wouldn't be enough power to save him," Leo told her. Still, he kneeled down prepared to break the rules for a man who had become his friend despite their obvious differences.

Paige's face contorted as she had a thought. "Aren't I half whitelighter? I mean, couldn't I use my half to offset his half?"

"It's worth a try. Take my hand," Leo ordered. "Hold your other hand over his wound." All of a sudden a bright white glow emanated from their joined hands and Cole fought for breath as he came to.

"That was good, right," Paige asked as Piper took her hand and guided her up from the ground.

"That was very good. Let's just hope it wasn't all for nothing," Piper answered.

Leo clapped Cole on the back. "Welcome back. You got lucky that Sam was able to find you and keep your heart beating."

"Thanks," Cole told the younger man, and Sam nodded his head.

Sam and Dean grabbed their drinks from the bar and made their way back to the booth where Leo, Cole and the girls were seated.

"Nice bar," Dean said and took a swig of his beer.

"Thanks," Piper said.

"Can I ask you guys a question? Is their any particular reason why you took this case," Phoebe asked. "You had to know the cops would be investigating and nothing screamed 'supernatural', so why did you come here?"

"I knew Prue," Dean answered after a long silent moment. "A long time ago we passed through San Francisco on a hunt and I met Prue at school. We went out together one night and we were caught in the middle of a hunt. Your Grams was pissed off and basically told us not to come back to California," he said, conveniently leaving out the part where Grams had wipe both him and Prue of their memories as well as any other information he had about Patricia. "I just figured that we owed it to her to find whoever did this to her."

"Do you guys have any plans for getting back on the road," Piper asked. "We have an extra room now," she said sadly, "and we could use some help now that Prue is gone."

"I don't know," Dean said. "There are a lot of cases out there for us to work."

"San Francisco is a hot bed for demons," Leo said. "I know it gets tough living on the road. This is a good place to settle down if you want to keep hunting and want to have someplace to call home. Plus, we have friends in the police department that help keep us off the grid. Just in case you decide to stay," the whitelighter told them.

"That'd be nice," Sam said. "You know, until we find something else," he finished saying when Paige walked up and his mouth hung open a little at the slit in her pink dress. "Hi," he said unable to take his eyes off of her.

"Hi," she said with a half smile. Turning to Piper she asked, "Does this mean I get free drinks now? Oh, I didn't mean it like that. It's not that I really drink or… Okay. I'm just gonna go."

"No, don't go," Sam said, and Piper and Phoebe shared that all knowing sisterly look.

"I won't stay long. I just wanted to uh, come by and thank you. You know, for saving my life and all," Paige toyed with the hem of her dress.

"Come on," Piper told her. "There's something we have to show you."

"What?"

"What good magic can do," Phoebe told her.

The sisters went up to the attic after showing Sam and Dean to the spare room and made their way up to the attic. "There's someone we thought you should meet," Phoebe said to Patty after they summoned her, and Piper and Phoebe watched as their mother finally held her youngest daughter again.
