Summary: When Mulder and Scully are called to Vegas, Scully develops a connection with a certain CSI night shift supervisor, which leads to them both re-evaluating and changing their own lives.

Author's Note: This is the long awaited CSI/XF crossover. I plan to write two versions of this story, one from a CSI perspective, the other from an XF perspective. Both will be posted in their respective show categories. Please read and review and tell me what you think. This is the X-files version. (Truth of the Matter is the CSI version)

The sound of high heels clicking on the floor alerted Mulder to the approach of his partner. As she entered the basement office, he smiled at her.

"Hey Scully"

"You're here awfully early Mulder, what's the occasion?"

He smiled again at her, and she knew that look.

"We have a new case, don't we? And judging by the way your grinning like a Cheshire cat, I think your excited."

"Ever been to Vegas Scully?"

"Yes" she answered flatly.

"Oh right! You and the gunmen" he laughed, remembering what had happened.

She gave him her own signature look, complete with raised eyebrow, signalling that she was not impressed. He immediately stopped laughing.

"That was a trip I would like to forget."

"Well how about making some new Vegas memories, cause that's where we're headed."

"When and for what reason?"

"There have been three reported disappearances out of the same park there, and only one body has been returned, complete with markings in the middle of the desert. We leave in a few hours, I'll pick you up from your place" Mulder replied, getting up and gathering his things.

"And we need to go and investigate this why?" Scully asked, again raising her eyebrow.

"You can read the case file on the plane. Go home and pack, cause we're going to Vegas baby!" Mulder answered, brushing her shoulder on his way out.

Scully just stood shocked in the office, wondering why she even put up with her partner sometimes.

"I cannot believe this Mulder! Your dragging me all the way to Vegas for a case that hasn't even been confirmed as an X-file yet!"

"It technically is. They have no evidence to point to a logical explanation for the disappearances yet"

Scully glared at Mulder. They were on the plane, half way there already.

"Any information that even remotely connects this case to us is based on pure hearsay! The witnesses are not credible, the papers have obviously taken their own spin on this. No wonder you didn't let me read the case file till we got on the plane! How did you even get Skinner to approve this?" Scully demanded, her voice raising slightly.

A few people sitting around them turned to look at the agents.

"You're making a scene Scully" Mulder said calmly.

Scully stared angrily at her partner.

"A scene? You'll get a scene when we arrive there and everyone thinks your insane!"

"What about you? You're going to be with me."

"Shut up Mulder!"

She turned away as best she could from him, and didn't talk to him for the rest of the trip.

Mulder guided the rental car through traffic trying to locate the building they were going too. Scully had only spoken to him when necessary, still mad at him. He glanced over at her in the passenger seat, and attempted to talk to her.

"You know, if we have some time when this is over, we could hit the slots, have some fun, say we were finishing up the case."

"How professional."

"Come on Scully. Tell me you don't want to have a bit of fun here."

"I want to be at home, not investigating this case with you."

"Ouch Scully. Was your trip with the gunmen that bad?"

"Just stop now Mulder. We're here, let's just get this over with."

He parked the car and they entered the building. They found the front desk and asked where they could find a certain Gil Grissom. They were directed to an office down the hall. As they came to the doorway, Mulder knocked and said,

"Hi, I'm Agent Mulder with the FBI, this is my partner Agent Scully. Are you Gil Grissom?"
