Warrick remembered the least out of everyone. He remembered that Grissom had told him to go to the security booth and look at some of the footage. Just as he had started to head over there, he felt a light touch on his arm which was a touch that was distinctly Catherine's. He and Catherine began exchanging subtle flirts over what could be on the security footage. Warrick couldn't remember how they connected flirting and security tapes, but they did. He and Catherine had danced a sort of flirting tango for years. Between her divorce to Eddie and Warrick's many pitiful relationships, they found comfort in flirting with each other. Warrick was just going to give Catherine yet another compliment when he heard Grissom's haggard voice yell something and then Warrick's world went black.
Earlier that Day
Grissom stood alone in the center of the casino. He surveyed all of the police officers and CSI's in action. He thought about how small and miniscule he was in all of this. Yes, he was supervisor of the night shift, but it would take his team, the other shifts at the lab, the lab techs, the detectives, the police officers, and the witnesses to solve this case. As Grissom continued to survey his surroundings, he noticed that Catherine was not at her post with Nick and Greg. He looked around a little more and spotted her with Warrick near the security booth. Grissom chuckled to himself at the sight of them. He and everyone else in the lab knew that they both liked each other. They also knew that Catherine and Warrick tried to hide to it, but it was no use. They would try to keep their glances secret, but someone would always see. They would also try to keep their flirting hushed, but someone would always hear. As Grissom was thinking that he should go over there and tell them to get back to work, a realization dawned on him. Did everyone know about how he liked Sara and how she liked him? Grissom's heart started to pound at the thought of this, but it was disrupted for a second when Grissom saw a bunch of men enter the casino.
"Who are they?" Grissom said aloud to no one in particular and that's when he saw them. He saw black, shiny, metal rifles under the men's trench coats. In an instant Grissom's heart started to pound again, but this time in terror.
"Everyone down!" Grissom screamed.
For a moment, Grissom just got wary looks from everyone since they didn't know what he was talking about, but then the first shot rang out. That first shot reached the ears of everyone in that casino. The next moment the casino was filled with more gun fire and screams as everyone hit the ground.
What everyone didn't know, was that Warrick Brown was the first to hit the floor because that first shot had just missed hitting his chest. Catherine Willows was the second to go down because after Warrick dodged the bullet, he hit his head on a nearby table and fell forward right on top of her.
The third and forth bodies to hit the ground were also members of the CSI team: Greg Sanders and Nick Stokes. Greg Sanders was the first one to be hit with a bullet, but he was only hit in the arm. At the sight of blood coming from Greg on the floor, Nick realized the true danger that they were in and hit the deck.
After Nick, everyone began to fall except for two people: Sara Sidle and Gil Grissom who were both looking for each other. Sara spotted Grissom first and tried to call out to him, but it was loud for him to hear her. All of a sudden a bullet whipped right by her head and her ears began ringing. She immediately collapsed from the pain of her ringing ears. Grissom was still looking around him and for a moment she didn't know why, but then it hit her that he was looking at her.
Grissom felt like his heart was going to explode from hearing all of the screams, and seeing all the blood, but mostly from not being able to see or hear Sara. Finally his eyes locked with hers. He forgot that he had asked her to print the poker table that was only a few feet away from him. Amongst all of the noise he managed to breath a sigh of relief, but that sigh was cut short by a scream, a scream coming from his own mouth as he felt the pain and saw the blood coming the bullet wound in his leg. He hit the floor with a thud, but amazingly never lost eye contact with her, and he saw how her expression changed from scared to worried as she took in his injury. He could tell from the look in her eyes that she wanted to be holding him at that moment, but she couldn't in fear that they would both would be killed. As he stared at her, Grissom began to only think about Sara, in order to combat his feelings of physical pain. He thought about how much he loved her hair, her smell, her laugh, her jokes, her clothes, but most of all her. He thought about how stupid he had been towards her by leading her on so many times and then cutting contact completely. Grissom thought that if they managed to survive this, he would tell her everything he had been thinking about during the reign of bullets. Grissom's thoughts of Sara were halted sometime later when silence filled the air of the bloody casino, but just as the silence came, it left, and a sound just as horrible as gun shots filled the air.
