Chapter 1

Three friends who had known each other for going on five years had decided to visit Las Vegas as a graduation trip. The three were having a hell of a good time dancing and drinking. An older man in is late twenties walked up to the brunette while her two friend were out dancing. The gentleman offered to buy her a drink.

Dawn went to the bar to rest for a bit as her two Slayer friends continued to dance and draw a crowd. When an older guy offered to buy her a drink, the young Summers thought nothing of it and accepted. After finishing her drink Dawn started to feel woozy, so the guy offered to call her a cab.

A drugged and spaced out Dawn was dragged down an ally by the man who bought her a drink. As her attacker started to strip her and himself, Rona and Vi had exited the club calling for their friend. Dawn started to become more aware as her attacker thrusted himself deep inside her. She screamed loud enough that both Rona and Vi heard her over the music of the club. The man pounded into her quickly before he got off. Pulling out roughly the rapist bolted away from his victim just as the two Slayers entered the alleyway.

Rona pulled out her cell and called 911 as she and her redheaded friend tried to calm Dawn. Vi had also pulled out her phone to call the Council's United States House to get a message to the Scooby gang overseas.

At the lab, Grissom got a call from Sofia about a rape case that happened to match one that Andrew was working on. The bug man called all his CSIs to the break room. He was glad to have his team back together after the fiasco of Andrew being buried alive. He looked over his team knowing they all thought he didn't know about some of the relationships that had started. Grissom first studied his two youngest CSIs, Greg and Andrew got off on the wrong foot because of Andrew's promotion happened so quickly but now the two got on great. He also noticed that Greg would periodically glance over at the Texan. Grissom then looked over at Nick himself and saw Warrick and Nicky joking around. He also noticed that Greg wasn't the only one taking glances in their partners direction, Warrick was glancing at his fince ever one in awhile to make sure he was still there. He then last but not least glanced at the two women on his team as they sat at the table drinking their coffee waiting for him to start.

Clearing his throat he spoke, "Alright assignments, Catherine, Andrew, I need you two to meet with Det. Lehane at the hospital to collect evidence and a statement from the victim. While Warrick, Greg and I will head to the scene where Sofia is, Sara and Nick you have a DB on Henderson Brass is waiting for you there."

Catherine and Andrew met with Faith outside the hospital where she was hanging up her cell. The three entered and found out where the victim's room was.

Catherine asked, "So Det. Lehane, What do you know?"

Faith gave a grimace saying, "Vic's early twenties, celebrating a graduation with a trip to Vegas. Drugged then raped in an off alley. Or at least that's what Sofia got from the vic's friends. Just got off the phone when you two got here."

Andrew asked, "Where were you earlier, Fay?"

"Sleeping, I was off but you know on call. Plus my apartment's closer to the hospital."

"Thought you hated hospitals Faith."

The brunette detective stuck her tongue out at her brother as they entered the elevator to get to the victim's room.

Catherine scolded, "Children don't make me separate you two."

Faith winked at Catherine, "You could separate me anytime."

The older blonde CSI smirked before replying, "Oh honey, I don't swing that way. And besides aren't you eyes on a certain blonde Detective"

The Dark Slayer shrugged saying, "That's alright you're a total MILF." She then groans saying, "Am I that obvious?"

Andrew chuckled, "Yes Faith you are."

The three entered the room as Faith introduced them all, "This is CSI Willow and…"

The girl on the bed interrupted her saying, "Faith? Andrew?"

Both former Sunnydalers gasp, "Dawn!"

Catherine watched the three as both Andrew and Faith started to move towards the young woman named Dawn. She called out, "Freeze. Andrew, Faith, both of you know procedure. You can't touch the victim until she's been processed. Andrew since you know her you can't handle the evidence if you want to catch this perp and make sure he stays in prison for good."

Both Faith and Andrew nodded before stepping out of the room. Faith got on her phone calling Brass, "Hey Jim. I can't work this case. "

Over the line, Brass asked, "Why?"

"I know the victim and from the description of the witnesses that Sofia told me. Well I think I know them too."

Brass hummed, "Okay come take over these case. And I'll work with Sofia on that one."

"Got it." She hung up and looks up just in time to see a group of people she didn't want to see ever again, "Shit!"

Andrew had called Grissom, "Griss, I can't work this case, I have a conflict of interest."

Grissom asked, "Would you like to work with Nick and Sara on their case?"

"Sure." Andrew's head snapped up when he heard Faith's exclaimed curse. He watched as the Scooby gang stalked up to Faith.

Buffy was three feet from Faith when she swung out at her Dark haired counterpart. Willow and Xander both glared at the two in their minds cowards.

Catherine had come out of the room just in time to see a petite blonde woman swing on Detective Lehane. Calling out, "You know you could get arrested for assaulting a law enforcement officer."

Faith chuckled as she had ducked the swing saying, "Not really Cath. I'd like you to meet Ambassador Summers. She's your vic's older sister."

Buffy snarled, "Don't call my sister a vic."

Faith sneered at the blonde, "That's what she is. And personally I don't know if she's one of the lucky ones or not. The bastard who did this is a serial rapist/killer, B. So most of his victims end up dead, but Ms. Muffet in there now has to live the knowledge that she was raped."

Giles decided to try and calm everyone down asking, "Faith what are you and Andrew doing here?"

Xander added, "Yeah last we saw you two, were running with your tails between your legs."

Catherine raised an eyebrow before answering for her co-workers, "Faith's a LVPD Detective and Andrew's the youngest CSI in our lab. Both are amazing at their jobs." The older CSI then turn disregarding the new arrivals to talk to her co-workers, "Faith, are you and Andrew working another case?" At their nods she continued, "Well you should get going."

Willow huffed, "If they're so good at their jobs then why are they leaving?"

A gruff voice from behind the Scoobies said, "It's a conflict in interest. If either Lehane or Wells worked this case and we catch the guy who did it the DA could use their connection to the vic as a way to overturn any convictions."

Faith spoke up saying, "Jim, you have anything for me on Sidle and Stokes' case?"

Brass gave a small smile, "Yeah, kid you need to head to the Strip to find the husband. Vega and some Uni's are covering the scene."

The Scoobies all asked if they could go in. As both Brass and Catherine studied their young co-workers, the older CSI asked, "So how the Mayor and Sheriff taking this case?"

Faith sighed, "Well it should end up as a high profile case. Vic is the sister of a foreign Diplomat and the adopted daughter of a Queen's knighted English gentleman."

Brass asked, "How do you know this Lehane?"

Andrew and Faith shared a look before the brunette answered, "Just because they didn't keep tabs on us didn't mean we didn't keep tabs on them."

Inside the room, Willow put up a spell that kept the nature of their conversation from being known by those outside the spell. Buffy was fuming the first time she sees her dark haired counterpart in five years and it's because her sister was raped.

Xander spoke up, "So who thinks that the LVPD is crazy to give Psycho Slayer a .9mm gun?"

Dawn whimpered from the bed, "I wasn't just imagining that. That really was Faith and Andrew?"

Giles walked to one side of Dawn's bed and offered the young woman in it his hand as he replied, "Yes my dear it was. And according to a couple of their superiors the two of them are quite good at their jobs."

Buffy scoffed, "if they're so good at their jobs why didn't they prevent this from happening?"

Giles sighed, "They are law enforcement. They are not clairvoyant."

For the rest of the visit, the Scoobies tried to take Dawn's mind off what had happened to her. All the while thinking why did everything bad that happens to Dawn happen on a Tuesday.
