Catherine and Sara were sitting in the Denali, heading back to the lab. "Tony's dead, who else could still hold a grudge?" Sara said, more than a little freaked out. "I'm not sure…he was in jail, maybe he had some friends who got out before him," Catherine added as she turned a corner. Sara shuddered at the thought. "Okay, Grissom said to go back to the lab since there are people there. They're less likely to try to find us there," Catherine said. Sara nodded.

They parked in front of the lab and waited a minute before unlocking the car doors. Sara got out first, followed by Catherine. They stepped out and closed their doors. They quickly turned around to see Warrick, Nick, and Greg behind them. Sara and Catherine both jumped. "Jesus!" Catherine said panting. "God, guys!" she said still trying to catch her breath. "Sorry," they all said at different times. "Why are you guys so tense?" Warrick asked. "Um…no reason," Sara said and they both headed into the lab. They went to the locker room.

"Okay, we can't let Warrick, Nick, or Greg know what's happening," Catherine told Sara. "I know, but what are we supposed to do if those guys find us?" Sara said opening her locker. "I don't know…" Catherine said opening up hers as well. Sara sighed as she put her bag inside and closed it. "Hopefully, Grissom will be back soon," she said. Catherine didn't reply. "Uh…Sara…" she said pointing to something inside her locker. It was on the door. It was another note.

"Think you're safe inside the lab? Think again. We'll strike any time, anywhere. So be on your toes."

"Dammit," Sara said resting her head against a locker. "We're not safe anywhere." "Just stay calm…" Catherine told her. "Maybe…maybe Grissom will have another plan." Sara and Catherine headed to the break room and sat down, each shaking at the thought that they weren't safe anywhere. Catherine had fallen asleep and she later woke up to see that Sara wasn't in the room any longer. "Sara?" she looked up to see no one. She walked around the lab and she didn't see her. Then, she worked up the courage to go outside, and she saw Sara sitting on the sidewalk.

"Sara, what are you doing outside?" Catherine asked her. "I need to get some fresh air. I felt like I was suffocating in that lab…" she said looking at the ground. Catherine knelt down beside her. "Sara…you know what I'm going to say…" she said sighing. "I know…I'll come in soon," Sara said. Catherine sat next to her. "So, are you still afraid?" she asked her. "…Of course," Sara said looking at her. Catherine smiled. "Me too," she admitted. "I've never been this scared since Eddie's car went off the side of the road and Linds was still in it," she said looking down. Sara looked at her and then turned away. At least she knew she wasn't the only one frightened.

Sara began to say something, but she suddenly felt really tired and the whole world turned black. The same with Catherine happened.

Grissom came back later, stepping out of his Denali. He walked inside the lab carrying numerous evidence bags and set them down in his office. He then went to look for Sara and Catherine. "Sara? Catherine?" he said looking around for them. There was no trace of them in the break room or the locker room. He went into Ballistics to see Warrick, Greg, and Nick inside, comparing bullet fragments. "Have you guys seen Sara and Catherine?" he asked them, more urgency in his voice. "Um…not for about three hours, why?" Nick said looking up from a microscope. Grissom disappeared.

"Damn, damn, damn, damn…" he thought to himself. "I should've come with them. Now they're gone and we have no idea where they are…" he thought as he walked into his office. He noticed something on his computer screen as he sat down. There was flashing text that kept getting bigger and bigger every time it flashed again.

WE HAVE THEM.

WE HAVE THEM.

WE HAVE THEM.

Grissom was now in a state of panic. Nick, Warrick, and Greg walked into his office. "Hey Griss, can you phone Brass and see if he can get us a warrant to search this guy's house?" Nick asked him. Grissom didn't say anything. They walked over to him. "Um…Grissom?" Greg asked moving closer to him. They looked at his computer screen. "Grissom…what's this about?" Warrick asked, looking at him.
