It was the sudden blaring of his alarm clock that jolted Greg from his deep slumber. He slowly realized that after the extended and exhausting shift he had slept the entire day, he was now glad that he always kept his alarm set. Kicking off the sheet, that he must have wrapped around himself sometime during his sleep, Greg got up and headed drowsily into the bathroom.

Ignoring the sudden cold of the tiles beneath his feet, Greg went straight into the shower, tossing the previous day's clothes in a pile on the floor. He turned on the pulsing water allowing it to help wake him up, and wash out the flaking hair gel that had hardened while he slept. He mentally reminded himself not to go to bed without washing it out of his hair ever again.

Within half an hour, Greg was dressed and made his way into the kitchen. His growling stomach informed him that he had missed at least two meals that day. However since he lived opposite most of the world, he was not really sure which two.

Scrounging up some dinner-breakfast that could be cooked in the microwave Greg popped it in for the required time. Before sitting down at the small kitchen table he cleared off an old paper to make some room for him to eat.

He really needed to clean his place up, he decided absently. He was always so organized at the lab, and he used to be more organized at home too, but now that he was practically living at work, things had gotten a little out of place. Not that Greg was a perfectionist, but the mess in his apartment was really starting to bother him.

After downing the food, Greg tidied up slightly before he headed out for what was undoubtedly going to be another long shift. The night lights of Vegas were on full as Greg Sanders arrived at the crime lab's parking lot.

Before starting his shift, Greg stopped by the locker room. There, he found one of his former team members, Nick Stokes, getting ready to head after his just ending shift.

"Hey, Greg." Nick said greeting the younger man with his mild Texan drawl.

"Hey," Greg replied back. "You getting used to the new hours yet?" He asked, although he doubted very much that the Texan had, he was not even used to them not working together anymore. Not that he minded Sophia, but he really did hate not seeing his three friends who were now working the swing-shift.

"Nope." Nick muttered darkly. He seemed rather alert now, but then his body was convinced that his shift should be just starting. Greg was willing to bet that Nick had been dead tired at the beginning of shift.

Closing his locker, Nick looked over at his younger friend, "I heard you're working a bombing." He said, carefully watching as Greg paled slightly. "You managing all right?" he added quietly. The entire graveyard shift had been close, and even though Greg had been the latest addition to the team, Nick could still guess how the spunky young man would be reminded off the lab explosion.

Greg simply nodded, it always surprised him how easily Nick could read him. Nick rested his hand momentarily on the shoulder of his favourite ex-lab rat, "You know, I'm around if you need me." He said as he headed out of the locker room.

Realizing his shift was starting, Greg quickly finished in his locker and dashed out into the hall where he narrowly missed hitting Hodges. Up ahead he saw Grissom and muttering a brief apology to Hodges, he hurried to catch up with his supervisor.

"So were do we start tonight?"Greg asked in his usual over-perky manner.

"You get to start to try to re-assemble the bomb." Grissom replied, "Sophia is on a case but Sara will help you," he added seeing the stunned look on the younger CSI's face. "I'll be in the morgue. Although, in cases like this, the bodies don't have much to offer the case. Usually identifying the components of the bomb is what helps the most." With that said, Grissom turned and headed off leaving Greg standing alone in the hallway.

He had never even seen a bomb, how was he supposed to put one back together? With a sigh Greg spun on his heels and headed off to the evidence room.

He found Sara already in the process of spreading the many collected pieces, and their corresponding pictures, across the large luminous table. He came up beside her and stared at all the evidence bags, each containing a small object, which when all placed together had made a lethal weapon that had tragically cut short the life of four teenaged boys.

"Hi Greg." Sara said, not looking up from the table. "You here to help?"

"Yeah." Greg replied, slowly walking around to the far side of the table where more pieces were. He stared blankly at the disassembled pieces before looking up at the brunette across the table. "Hey Sara?"

"Yeah?"

"I have no idea what I'm doing." The young CSI admitted.

Sara grinned and moved aside to let Greg see what she had done so far. She had just started to explain how certain parts of the bomb worked when Brass interrupted from the doorway.

"So your working this now too?" He asked Sara who nodded in response. "Well I haven't got much for you yet, but I've only talked to a few teachers so far."

"Well Griss is checking out the bodies now," Sara said filling Brass in on their end. "Greg and I are starting to sort out the debris here." She added gesturing to the spread of pieces on the table before them.

"I've got a few more teachers to talk to in the morning," Brass said glancing at his watch, "Hopefully I can turn out a suspect for you to try and match that bomb to."

"You know where to find us." Sara called as Brass turned to exit, leaving the two CSI's to figure out the evidence part of the investigation.

"So do these go together?" Her young spike-haired colleague asked holding up two similarly shaped pieces.

"Probably," Sara replied as Greg handed her the parts, "They look like they could be part of a timer."

"So if the bomb was on a time-delay, how long before it went off could it have been planted?"

"Well, different timers have different limits," She explained, "If we can figure out what kind of clock this one came from, we might be able to figure out about how long the bomb was there."

Greg nodded as he went back around the table. The two CSI's worked in an intermittent silence, broken whenever Greg had another question. Sara did not mind explaining things to the eager to learn CSI level one. She admired how enthusiastic Greg was about learning to work in the field.

After some time, they had figured out most of the bomb's structure, and Sara could guess at most of the components. However, she still did not have the actual triggering piece. She remembered glancing at a picture that could have been a possible trigger she went back to the pile of pictures that now rested at one edge of the table.

Finding the picture she had been looking for she held it out toward Greg, "Greg?" She asked. "Do you see this piece over there?"

Carefully Greg examined the pieces around him, but found none that seemed to match the picture, "No, why?"

"I think it might be the triggering-part," the tall brunette explained slowly, "And I can't find it anywhere."
