Grissom was sitting in his office when Catherine and Warrick stopped in the doorway midway through shift. He looked up at them over the rim of his glasses and motioned for them to come in and close the door.

Catherine was the first to speak. "What's going on, Gil?" Concern was evident on her face.

"I'm not really sure right now. Nick took Sara home and he's going to try and talk to her." Grissom removed his glasses and rubbed his temples. He felt a migraine coming on full force.

"She wanted to kill herself." Warrick spoke with disbelief in his voice. He and Sara hadn't really hit it off when she'd moved to Vegas since she'd been brought there specifically to investigate him, but over the last couple of years they'd formed a good friendship and he thought that he would have noticed if something was wrong.

Grissom nodded and when he spoke, his voice wavered a bit. "Yes, she did."

"How did we not notice something was wrong?" Catherine's question was as much to herself as to Grissom and Warrick. "Some CSIs we are."

Warrick furrowed his brow in frustration. "Catherine's right. How did we not notice?"

Grissom shook his head and put his glasses back on. "I don't know, but we didn't. We all missed it. If Nick hadn't followed her up to the roof, I'm not sure what would have happened."

"Did she say anything?" Catherine queried him.

"She just seemed to be very troubled; something about wanting it to stop hurting. She didn't mention anything specific." Grissom glanced at Warrick and then back at Catherine. "I should probably let you know what happened after shift yesterday."

Warrick looked immediately worried. "What do you mean? Nick and I were with her, what happened?"

Grissom's expression was unreadable as he looked at Warrick. "How much did she have to drink?"

Warrick furrowed his brow. "I don't know. Two or three beers, same as Nick and I."

Catherine had a measured quality to her voice. "What happened, Gil?"

"She got pulled over. They called me to pick her up." He confessed with a heavy sigh. He wished that he could have gone back in time and said something, anything to get her to talk. She had just looked so ashamed of herself that he didn't want to press.

"What did you say, Gil?" Catherine narrowed her eyes at him suspiciously.

Warrick remained silent wondering how he hadn't noticed that Sara was too impaired to drive.

"I just dropped her off at her apartment and told her to sleep it off. She didn't really seem like she was in the mood to talk." Grissom explained.

"They didn't cite her, did they?" Warrick concluded since Sara had come into work. If she had been, it would have been grounds for an immediate dismissal or at the very least a suspension.

Grissom shook his head. "No, they didn't." He looked from Warrick to Catherine with a slightly helpless expression on his face. "I thought she needed me to cut her some slack. I didn't really think there was more of a problem."

"You think she has a drinking problem?" Catherine queried.

Grissom shrugged his shoulders. "I don't know. Maybe Nick will be able get her to talk."

"What are you going to do, Gris? She can't just come back to work and pretend that she didn't try and jump off the building." There was an edge of anger in Warrick's voice; anger at Grissom for not being more intuitive when he'd picked Sara up at the police station and anger at himself for not recognizing the signs that something was amiss with her himself.

Grissom knew that Warrick was frustrated. He was frustrated himself. "We all need to do something. I think we all know Sara well enough to know that the worst thing for her would be to go on suspension."

"Agreed." Catherine interjected, glancing over at Warrick.

Warrick nodded. "Yeah. We all missed it. I could kick myself." He was clearly upset.

"Warrick, we can't beat ourselves up about this. We just need to help Sara." Catherine reached over and put her hand on his shoulder, giving it a squeeze.

He nodded. "I know."

"Catherine's right. All of us need to keep an eye on her and I think the best way to do that is if she's at work." Grissom let out another deep breath. "Nick said he would call me when he had a chance and let me know what's going on. I suggested to Sara that she talk to a counselor and she balked at the idea."

"Of course she would. She stubborn as hell." Warrick commented, rubbing his temples.

"I think that's probably what she needs though." Catherine had a studied expression as she tried to think back to anything that might have been a tip off that Sara was that close to the edge.

They were all quiet for a few moments and then Catherine spoke again. "How's Nick?"

Grissom furrowed his brow and shook his head. "I'm not sure. He looked pretty shaken up."

"I think we all are." Warrick quipped. Seeing Sara like that with Nick pulling her off that railing had shaken him to the core. He was thankful that Nick had used his gut and followed her. Of all of them it seemed that Nick was the only one who had noticed something was wrong and had taken action.

Grissom looked a bit haggard. "I think for the time being, this stays here. I don't want what happened with Sara to become gossip in the hallways."

Warrick nodded in agreement. "No argument here."

"What about the officer who brought her in?" Catherine queried him.

Grissom leaned back in his chair before he answered. "Officer Fromanski owed me one. Now we're even."
