"Careful," Prentiss hissed.

Morgan paused long enough to shoot his partner in crime a look. She was not helping by hovering over him like this.

"I am!"

"Shh!" she told him with a frantic motion.

He gave her an outraged look; she was the one who was doing all of the talking! She just returned with a pointed look. Grumbling, he continued on with his task. It was a very delicate one, he had to be very careful. One wrong move and this whole thing wouldn't happen.

"And what are you doing?" he demanded in a harsh whisper.

"Keeping an eye out!"

"He's right here, I can see him," he told her. "It's him we need to keep an eye on."

Both of the agents looked down at the person in question between them. Reid was completely immersed in his work and didn't appear to be aware of what was going on. Well, he probably wasn't. The work he was doing was the type he loved best and he would have stopped them by now if he knew what they were up to.

"I'm looking out for JJ, actually," Prentiss told him with a sniff. "You don't want her spoiling it."

That made Morgan stop for a moment. She had a point. Their resident Media Liaison would definitely not approve of what they were doing and would certainly put a stop to it. And that wouldn't be any fun.

"She's on a conference call," he dismissed. He'd heard her tell Hotch that she'd be unavailable until four.

This was literally the perfect window for what they wanted to do. If people would do what they needed to do and not try and micromanage everything.

Reid made a squawking noise between them. They froze and held their breath but he didn't look up or give them any indication that he knew they were there. They didn't do anything for a minute just to make sure. Nope, his head was back into the paperwork. Phew.

"Go fix the clock on the wall," Morgan whispered, giving her a 'helpful' shove.

She glared at him but he looked pointedly down at their vic-, at Reid. With another huff, Prentiss spun around and made her way over to the wall. Morgan had no clue how she was going to get the clock off the wall and he didn't care.

He had his own problems to worry about.

"This doesn't make any sense!" wailed Reid, miserably staring out the window of the BAU.

"It's true though," Prentiss said with a smirk.

"But it's scientifically impossible," he reiterated, rubbing childishly at his eyes.

"Obviously not," Morgan said, winking at Prentiss over the top of their resident genius' head.

"It's only three oh seven! It should be happening at eight oh nine!"

The partners in mischief blinked at him. They didn't know whether to be stunned that he knew the exact time it was or that he knew the time of the sunset tonight. They really shouldn't be surprised.

Before they could question this newest freakishness, JJ questioned, "What should be happening at eight oh nine?" having been torn from her office at Reid's wail.

It was never a good thing when she could hear that. It meant that someone had wound him up too much, something that JJ would never, ever tolerate. She thought that they all knew that. Especially the two daft Agents in front of her.

"The sunset! It's too early!" Reid said loudly, sounding increasingly distressed with each syllable and waving his hands at the windows.

Other agents were giving him a wider than usual berth. A distressed Reid was something they couldn't compute. Of course, the fact that he looked somewhat crazier than usual didn't help.

Reid had spent the whole day following an extremely long and convoluted paper trail with glee. He had gotten so absorbed in it that he'd only had one cup of coffee. Unfortunately, his appearance reflected that. His hair was standing on end, more so than usual, from running his hands through it and there was a slight glazed look in his red-rimmed eyes. He had only felt the lack of caffeine in his system when a door had slammed causing him to jerk up from his desk. It was then that Reid had noticed that the sun had set.

"Spence, it is eight oh nine," JJ said patiently, patting his arm and giving Morgan and Prentiss a suspicious look.

What on earth had they done now? They both grinned innocently at her. Yeah, that didn't make her feel any less suspicious.

Reid raised his right hand, holding his pocket watch aloft, and pointed at the office clock with his left. "No! It's three oh seven."

JJ glared at Prentiss and Morgan, realising instantly what had happened, and turned to smile sympathetically at her best friend.

"Check your phone, Spence."

Reid scrambled or his cell phone to check the time and frowned at the screen. JJ showed him hers as well.

"Eight oh nine," she said gently. The digits on the screen changed from a zero and nine to a ten. "Or, close enough."

"Darn it, I knew we forgot something," Prentiss muttered to Morgan.

"We should have involved Garcia," agreed Morgan.

Neither of them sounded remotely apologetic. Both JJ and Reid noticed this. Reid spun around to glare at them. It looked more like a pout. He just couldn't be intimidating to them.

"This was a prank?"

They grinned at him.

"A pretty basic one, too!" Morgan crowed.

[xxxxxxx]

Reid's eyes narrowed at both of them. He supposed it was partly his fault. He usually had great time awareness but the lack of caffeine was getting to him or such an obvious prank wouldn't have worked. He hoped.

Prentiss and Morgan started to shuffle nervously. Was Reid going to be angry or -?

He suddenly smiled at them, hoping it came across as sinister.

"I need a coffee," he announced and swept off towards the break room. He would come up with a much better retaliation when he was properly hydrated. Or caffeinated.

Remembering his one cup of coffee, he nodded resolutely. Caffeinated it was.
