I loved the idea of having CSIs with superpowers, so here's my take.

A little Cath and Gil romance, maybe some Greg and Riley too, but that's definitely not the main focus here.

"One to go" ended after Catherine's wink to Gil. At least for me. Forget about Costa Rica, Grissom is a teacher at UNLV.

Langston is not in this history because I don't really get him.

Nothing is mine, obviously. If CSI was mine Warrick would be alive, Grissom would be at UNLV teaching and living with Catherine, Ray would still be a professor. Sara would be right where she is though.

"I don't get it."

"Do you ever get something, Greg?" Riley smiled in his direction. Greg just glared at her.

"Well Mis I Get Everything, enlighten me then. Why would somebody break into a lab where people are messing with Plutonium?" He smirked at her.

"Maybe they needed to go back to the future." Catherine cut the banter smiling. "Now get back to work, kids. You two continue processing here, Nick you get started in the doctor's office, maybe you can find a reason for somebody to break into here in there. I'll go process the other lab."

Everybody agreed and started doing their jobs.

Nick was going through loads of files until he found one that caught his attention. "Genetic Mutation Caused By Exposure to Plutonium" and as he read the file he found out why somebody would break into this lab.

"Where's Catherine?" He asked Greg and Riley as he ran into the lab they were processing.

"Processing the Plutonium lab, apparently whoever broke into here wanted to get there." Greg answered.

"Ok, you guys have to grab the most important evidence and leave here. Now. I'll go get Cath."

"What's going on Nick?" Riley asked.

"If these documents are right, people were messing with mutation here, human mutation and there are controlled Plutonium explosions programmed in that lab, but now that it doesn't have neither a door nor a scientist, I don't believe it's safe here. Now get these files and go". He said tossing the files into Greg's hands. Greg and Riley assented with their heads, and started collecting anything they could as fast as they could.

"Cath!" Nick called as he entered the lab. "We need to get out of here now!"

"Why?" She asked and Nick explained the same thing he had told his other colleagues. "And there's an explosion scheduled in ten minutes" he added.

"Oh my God" Catherine was pale.

"What's the problem, Cath?" Nick was even more worried now.

"The machine is broken already, I was processing it just now. There was a clock and it stopped five minutes ago. Nick run NOW!" Cath screamed.

"I'll go see if Greg and Riley left already, you get your evidence and go." Nick said and started running.

But it was too late, the machine exploded, and it wasn't a controlled explosion. Catherine was still in the lab with the machine, Nick was on his way to the other lab, Greg and Riley were still trying to collect all the evidence they could before running. All the four CSIs were hit by the big explosion.

As Catherine laid in what was left of the lab all she could think about was her daughter Lindsey and her friend Gil Grissom, and she could swear she saw them with very shocked faces and asking her what was going on before another explosion hit the lab, and she thanked God that her daughter was at school and Gil was teaching at UNLV. And she smiled before passing out.

Lindsey was in the bathroom gossiping with her friends when she had a vision. Her mother was in a lab that had apparently been completely destroyed, she and her mother's friend Grissom were completely shocked and asking her mother what was happening but before she could answer there was another explosion and she was back at the bathroom screaming. Her friends were so focused on gossiping that they only noticed Lindsey's black out when she screamed and then passed out.

Grissom had the same vision Lindsey had, but he was in his office at UNLV, he also screamed and a janitor came into his office to see if everything was all right, he found Grissom passed out.
