"Hey, Reid" Prentiss said and gave him a warm but tired smile as she walked into room the PD had set aside for the BAU investigation. "How's it going?" She asked as she looked up at the map.

"He's most likely driving an American made vehicle, something large that works with most terrains but specifically the deserts surrounding Las Vegas. So he'll most likely be driving some form of a small to medium SUV or a pickup truck" Reid relayed as he closed the first folder and opened the second, Megan White's.

"Don't burn yourself out, kid" Morgan said with a smile as he tossed a bit of Reid's hair into his face.

"Yeah, why don't we split the work and get it done quicker" Prentiss Said with a little smile. "Morgan can take the top two" She said as she grabbed Megan White's and Desiree Reid's folder and handed them over to Morgan. "I'll do this one and that one" Prentiss continued as she picked Abigail Moore's folder, which Reid had already looked through, and another folder of the pile in front of Reid.

"That leaves pretty boy with…" Morgan paused as he looked at the names on the folders. "Alice Wells and Cheryl Lawson" He finished and opened the first of his two files.

"Guys, these two were abducted in the 50's and 60's" Reid said unenthusiastically as he opened the two folders and stared down at them. "There's just the initial missing report and the parents' statements!" He exclaimed as he picked the two sheets up from each folder.

"You're complaining because you don't have a lot of paper work to do?" Morgan asked with a little laugh. "Here, I'll swap you" He said and offered him the two files of Megan and Desiree"

Reid smiled back at him and reached for the thicker files but Prentiss stopped him. "Hey, I paid for coffee on the way here. I get the easy work" She said and swapped her folders with Reid's, leaving Megan's and Desiree's in Morgan's hand.

"Ugh, fine" Morgan sighed and reopened the top file, Desiree's.

Reid gave another little smirk then looked down at the new folders as his eyes looked over the writing, quickly taking in the information. Morgan was a much slower than Reid and it took him almost a minute before he got to the parents' names. When he read Diana Reid he had to back track and reread it. His face screwed up the tiniest bit but he continued to read on until he read William Reid. His brain quickly started putting pieces together as he stared down at the two names until it clicked- Desiree was abducted in 1979, Reid wouldn't have even been born yet.

He stared up at Reid as the realisation of Reid having a sister sunk in before he dropped the files on the table, grabbed his phone from his pocket and hurriedly dialled Hotch's number once out of the room.

"Hotch, we've got a problem" Morgan blurted out. "One of the abducted girls is Reid's sister" he hissed down the line.

"We know" Hotch sighed and rubbed his forehead as if he had a headache while he drove down the busy streets of Las Vegas.

"We? Who else knows?" Morgan quickly asked back as he looked over his shoulder to make sure no one was listening.

"Just Rossi and Garcia" Hotch replied.

"We talked to Reid's dad and he didn't think Reid needed to know" Rossi added bitterly.

"Jesus… Well, how are we supposed to tell him?"

"His dad asked us not too" Hotch answered.

"And you're just gonna do what he says?" Morgan asked back angrily.

"No, I'm just telling you the facts" Hotch replied as he struggled to keep his emotions in check as Morgan questioned his loyalty to Reid. "We'll tell him when we get there which should be in ten or so minutes"

"I doubt it, the media's crawling all over the street outside" Morgan said quietly before hanging up, pushed the phone back into his pocket and walked into the room Prentiss and Reid were in.

"Who was that?" Prentiss asked and turned to Morgan who looked a little off balance and dazed.

"Hotch" He replied quietly, he knew they'd be able to tell something was wrong but they'd feel like this soon… especially Reid. Morgan quickly sat down, opened a file and pretended to read through it to avoid eye contact.

"What did he say?" Reid questioned as he looked over at his friend whose happiness had quickly faded.

Morgan's eyes flickered up at Reid for a moment and as their eyes made contact he quietly answered "He'll be here soon... He'll tell you himself"
