Reaching the scene of Grissom and Warrick's case, Catherine hesitated before getting out of the car. Sighing, she got out and looked around. She spied Warrick crouched by some bushes. "Hey, War," she called as she approached.

Warrick turned and gave her a surprised look. "Hey, Cath. What are you doing here?"

"Is Grissom inside?" she asked, ignoring his question.

"Yeah. You okay?" he asked, noticing that her eyes were watering.

"I'm fine," she lied. Seeing Warrick's look of disbelief she continued, "Look, I'll explain later. Right now I've got to take Grissom with me to another case. You alright to finish this up by yourself?"

"Yeah," he replied, nodding. "We're almost finished here anyway. You sure you don't want to tell me what's going on?" Once again Catherine ignored the question. She turned and made her way into the house.

"Grissom? You in here?" she called.

"Catherine?" Grissom said entering the front room. He noticed that Catherine had her head down and was trying to avoid his gaze. "What's the matter? Did something happen to Lindsey?"

"No, Lindsey's fine," Catherine replied, still not looking him in the eye. She knew she had to tell him, but she didn't know how. "Look, Grissom, Warrick's going to finish up here. I need you to come with me."

"Catherine, what is this all about?" Grissom asked, starting to get a bit impatient. He was really starting to get worried.

"Gil, please, just come with me," Catherine said, practically begging. She didn't use Grissom's first name often. She usually saved it for important moments. Her use of it this time didn't help with his unease about the situation, but he agreed to go with her without further question.

Grissom said good-bye to Warrick and got into Catherine's car. They drove in silence until Grissom couldn't stand it any longer. "Are you going to tell me where we're going?" Catherine nodded, but didn't reply. Grissom sighed and went back to staring out the window. He knew he wouldn't get an answer out of her until she was good and ready.

Catherine glanced over at the man sitting next to her. A lot of people though he didn't have emotions because he was able to shut them off when working on a case. Catherine, however, knew better. Grissom cared a lot; he just wasn't always good about showing it. Only those closest to him got to see that side of him. Now, one of the people he was closest to was dead. Sighing, Catherine pulled into a parking space and stopped the car.

"Care to tell me why we are at a park when we're supposed to be working?" Grissom asked dryly, turning to look at her.

"Gil, I don't really know how to tell you this…" Catherine began.

Grissom saw that whatever she had to tell him was tearing her apart. He took her hand and said gently, "Just tell me, Cath."

Catherine nodded. "Brass got a call about a double homicide. It's um… oh God, Gil, it's Judy. It's Judy and Phil."

Grissom stared at her in disbelief. "No," he whispered. "It can't be." Grissom was a man that rarely cried, but he could feel the tears starting to form in his eyes.

"I'm so sorry, Gil," Catherine said, pulling him as close to her as possible in the car. They sat there for a long time, just holding each other.

Finally Grissom pulled back and wiped his eyes. "Who's working the case?"

"Nick and Sara are processing the scene," she replied. "I told Brass that I'd be heading the case as soon as I told you." Grissom opened his mouth, but Catherine beat him to the punch. "And no you can't work this case. Brass already put his foot down." When he looked like was going to object she continued, "Gil, you know you can't work the case, so please just let me handle it. I'll keep you informed of everything." Staring him down, Grissom finally nodded, knowing it was for the best.

"Has anyone told Lacey?" he asked quietly as Catherine started the car.

Catherine shook her head. "I thought you should be the one to tell her."

Grissom nodded. "Is she at school?"

"Yeah, we'll stop there after we swing by the crime scene. You going to be okay there?" she asked, glancing at him. He took a deep breath and nodded. The rest of the ride was spent in silence. They pulled up in front of the house and got out.

Brass was standing in front, waiting for them. "I'm sorry, Gil." Grissom nodded, but didn't reply.

"So, what happened?" Catherine asked.

Brass glanced at Grissom, but sighed after seeing Catherine's glare. "Neighbor was taking her morning walk when she noticed Philip sitting in his car. She went to say good morning when she noticed that his throat was slit. She ran home as fast as she could and called the cops. They showed up, went inside, and found Judith in the kitchen."

"Was her throat slit, too?" Grissom asked hoarsely. Brass didn't answer right away. "Jim!"

Brass sighed. "Yes. I'm sorry, Gil." Looking at his friend, Brass noticed that Grissom was starting to look a little green around the gills. This surprised him a little. In the entire time that he had known Grissom, never once had the man come close to being sick, and they had seen some nasty stuff. 'Of course, it's never been someone he's been so close to,' he thought.

"Tell Nick and Sara that Greg is waiting at the lab for them, when they've finished here," Catherine said. "Grissom and I are going to pick up Lacey from school."

"What do you want me to tell them?" Brass asked. They were smart kids and they were bound to figure out something was up.

"You might as well tell them," Grissom replied. "They'll figure it out sooner or later." Not waiting for a reply, he headed back to the car. He wasn't looking forward to telling Lacey that her parents were dead.

"He going to be okay?" Brass asked, watching Grissom walk away.

"He will be," Catherine replied before following him.

Brass watched the two of them drive off before turning around. He was surprised to see Nick and Sara standing there. "What?" he snapped.

The two CSIs exchanged looks before Nick replied, "We just wanted to let you know that we were finished here and were heading back to the lab."

"All right. Greg's waiting for you. This case is top priority."

"How come?" Sara asked.

"Because the dead woman is Grissom's sister," Brass replied as he headed to his car, leaving the two shocked CSI's in his wake.
