Grissom peeked over his upturned desk at the figures marauding through the lab. They were the same as his team, down to the beyond-their-pay-grade fashion choices. Except one detail: Their glowing red eyes. And the rampant evil.
"They're obviously being powered by the Negadouble-Crystal we found earlier, Nick. We need to find that crystal and nullify it," said Grissom, ducking his head back down. "We haven't got much time - they're going to reach the evidence locker soon, and if they destroy the contents, we've lost the case."
Cath groaned. "But Greg dropped the Negadouble-Crystal in that barrel of other crystals! And all of those crystals were black and glowed ominously too! We'll never figure out which one it is!"
"I said I was sorry, okay!" said Greg. His head was in his hands. His double had wreaked absolute havoc on the lab, but most of all on Greg's secret coffee stash. Beautiful, expensive, delicious Hawaiian coffee beans were scattered across the floor as if to illustrate Greg's own clumsy folly with the Negadouble-Crystal.
"But that's the thing," said Grissom. "All Negadouble-Crystals are unique. Like fingerprints. We can do this, guys."
"And that explains how the killer's hands could fit in that space!" said Catherine, excitedly. She hitched up her OshKosh overalls which were slipping over one shoulder. They were purple and had a monkey on the front.
"And I bet if I could get my hands on some clay to neutralize it, I could reverse the effects!" said Warrick in his new squeaky voice.
They exchanged tiny high fives.
Greg came into the lab and groaned when he saw Warrick and Catherine gathered around a smoking petri dish with Grissom Knows What in their hands.
"Guys! Guys, stop running off. You're supposed to be in Griss' office with the others. And you know you're not allowed to play with the equipment while you're uh… Rugratty," said Greg. "Also? Brass, who is still the most responsible adult around here, says it's naptime."
Greg was one of the few who hadn't been caught in the wake of the explosive package that had reduced the CSI department to toddlers. His face had spent the last two hours caught between manic laughter and horror.
"It ain't naptime! We have a killer to catch, Greg!" said Warrick.
"He says you get really cranky without one, Warrick," said Greg, tucking them under his arms. "I'm sure you can 'solve the crime' when you're big again."
"Brass has it out for me!" complained Warrick. He squirmed and wiggled. "Cath! Get him in the kidneys! We've got to save the mayor from a two-foot terror!"
"Ow! GUYS!" Greg doubled up as Catherine landed a solid kick.
"We'll make it up to you later!" yelled Warrick as he raced out the automatic doors, Catherine hot on his heels. Greg lay behind them, curled into a tight whimpering ball.
Sarah put on the helmet to the time machine and strapped herself in.
"Not if we stop him. We have his prints. We can find Frank Keaton and save the future."
"I call shotgun!"
"Not this time, Greg," she said. "I need you and Archie here in the present feeding me results about the evidence. This thirty year old crime is going to need to be solved - here and now, if it's going to be of any use to me in the past."
"Aw," said Greg.
Sara warped out of time and Greg went to Archie's lab where the image tech was working on the evidence of Frank Keaton's 30 year old murder yet-to-be. All they had, so far, was Keaton's fingerprints and a grainy image from a security camera captured in the 80s.
"Zoom and enhance," sad Greg glumly.
"Oh, I do say, Jimmy, we've gotten into quite a pickle!" said one of the Brasses, straightening his bowtie. The other Brass, the one behind the wheel, glared at him. The very American Brass' hand snapped out gripped the bowtie'd Brass's collar to emphasize the imminent threat.
"We wouldn't be in a 'pickle', Willoughby, if you'd just stayed in the car like I told you," snapped Jim Brass, shoving Willoughby roughly and peeling out of the parking lot while the Mafia members fired on the car. He might have been driving one-handed, but Jim Brass was an old hand at getting in and out of the traditional Las Vegas mafia shoot-outs, at least until ratings were low.
"They simply said they wanted to say hello to the good Mr. Brass and I'm afraid you're not the only one who can lay claim to that title, chum," said Willoughby Brass, of Sussex England. He disentangled Jim's deathgrip from his prim suit, dusting it with one hand like it had American germs.
"And another thing," said Brass, taking a corner at speed, "Where do they get off taking me for you.It's insulting. One, I don't dress like I'm off to play water polo on the back of a manservant, two, we look nothing alike!"
A bullet whizzed through the back window and past Jim's ear.
"Hm, that delightful blonde vixen at your station said there was a striking resemblance. I do hope it was a compliment. Oh, mind the vagrant, Jimmy!"
The car swerved. Both Brasses tilted to the side.
"Gah!" yelled Jim Brass as they went off the side of an embankment.
The car flipped. Willoughby and Jim Brass leapt out the car doors just in time. The vehicle exploded into flames behind them.
"My car!" Brass moaned as he gazed at the burning wreckage.
"You know what this means, don't you, old bean?" said Willoughby. He was dusting off his knees, none the worse for wear.
"That I have no car?" said Brass. "I gotta call this in…"
"That they think we're dead now! And two Brasses are better than one when it comes to solving a bit of the old Mafia stabbing, wouldn't you say?"
Breaktime in the lab was a calm affair. Montage music could be heard from the lab as test results were gathered about the stabbing of a Mafia bigwig.
"That was his cousin. From England. Let's not get involved," said Catherine. "If we do, Brass might transfer to another department. From shame."
"Family can bring out all sides of people. I'm sure Brass likes his cousin just fine," said Grissom, prepping a racing cockroach with tiny cockroach-friendly racing stripes.
Nick burst in.
"Did you hear? Brass went in after that Mafia don and they blew up his car and killed him!"
The racing cockroach gasped.
I'll always have you"
"I got you too, babe
Even if it makes me… blue."
As the music died down, Warrick and Catherine were still holding hands and gazing into each other's eyes. The jazzy duet had briefly let them forget that they were tied up above an artisanal death trap from yet another dissatisfied former suspect.
Then they heard it.
Their prime suspect, Meredith Rhodes danced out, her tap shoes clicking and clacking on the floor, sparks rising up from their metal tips.
"That's right, CSI wunderkinds," she said, "this whole place is doused in gasoline and dynamite. If I go down, I'm going down dancing! Show's over, boys and girls!"
"Oh no you don't," sang a clear voice from the shadows. Grissom stepped out, hat in hand.
"Oh no you won't," from the other side. Sarah stepped into sight. silver-tipped cane in hand.
Their voices rose together in a single note as they began their own duet.
"Enough singing!" yelled Brass from the doorway and shot Meredith Rhodes in the leg.
"Fuckers!" yelled Rhodes as she went down.
"Someone read her the rights while I untie Warrick and Cath," said Brass. He stomped up to the hostages.
Warrick and Catherine muttered thanks and let go of each other.
"Looks like she saved the last dance… for us," said Grissom wryly.
