Sorry if this chapter doesn't really make sense but I thought i'd post it anyway. Hope you enjoy, and yes Lydia will get her cumuppance eventually. x

"I didn't do this, I can't explain it but it wasn't me." Sara tried, weariness showing in her voice.

"And what about the other times? I know you've done this before." Catherine challenged. Patient-doctor confidentiality aside, Nancy had done some digging on her behalf. Sara's face paled slightly at Catherine's revelation.

"Ok, I admit to that but this times different. I was desperate those times, I had no other option."

"Sara there is always other options, you can talk to someone. Talk to us." Sara didn't answer so Cath took a different approach. "Alright, we're scientists right? So, what's your theory? What happened?"

"Well, I didn't lock the door when I came home, maybe someone followed me in, hit me," she touched the cut on her head lightly as if to emphasize her point. "Made it look like I tried to kill myself."

"Ok, who? And why?" Sara shrugged. "Do you think Lydia could have done this?" Sara shook her head vehemently.

"No, never. Lyds wouldn't do this."

"Ok, so someone, but you don't know who, followed you into your apartment, knocked you out, carried you into the bathroom and slit your wrists." Catherine raised an eyebrow at her sceptically. "Honey, don't you think that's a little far-fetched? You were stressed, upset and you wanted the feeling to end. You hit your head when you collapsed." Catherine reached out and gently tucked a strand of hair behind Sara's ear, next to the shallow gash. Sara shook her head.

"I didn't do this Cath. I know I didn't. Its all wrong." She murmured to herself. Cath was saved from speaking when a clattering behind her caught their attention. They turned to the door, where Nick, Warrick and a sheepish Greg had literally stumbled through.

"Sorry, didn't mean to interrupt y'all." Nick grinned lazily, handing the flowers he was holding to Warrick and walking over to wrap Sara in a bear hug.

"Hey girl, what you done to yourself huh?" Warrick placed the flowers on the bedside table and took Sara into his arms once Nick had released his hold on her. She didn't speak but the young brunette looked at Catherine, hoping for her to help her answer that. Catherine didn't say anything, just offered a comforting smile and patted her leg softly. She noticed Lydia hovering in the doorway but as soon as she met her gaze the younger blonde left the room. Cath made an excuse and hurried after her, leaving Sara suffocating, now in Greg's strangling hug.

"Lydia, wait. I need to ask you…can you tell me exactly what happened when you found Sara?" Catherine chased after her, catching her up in the corridor.

"Look, I really…"

"Please," Cath cut her off, fixing her with the best pleading look she could muster. "It could help. Just tell me what you did, in as much detail as you can."

"I went to Sara's, unlocked the door – I have a key – the room was a mess, like Sara had thrown stuff around, magazines and things. I know what Sara's like, she can lash out at things when she gets upset, and can lash out at herself, and I thought that she might have done something stupid so I went to her room, then the bathroom and I found her unconscious, bleeding. She was holding the razor blade. I called an ambulance, then I held her, tried to stop the bleeding. That's all I can say." Catherine nodded as she spoke, listening intently.

"Ok, thank you. Erm, Sara mentioned something about speaking to a friend of hers, a school councillor?"

"Dan Fitzgerald." Lydia looked slightly puzzled when Catherine mentioned this, as if she wasn't aware of it.

"Do you know where I can find him?" Catherine probed further.

"No sorry, I don't know where he lives." Lydia smiled apologetically and Cath thanked her anyway before leaving. Lydia watched the blonde walk away, invisibly shaken by Catherine's questions.

Catherine sighed. Lydia wasn't kidding. She had gone back to the lab to get Sara's spare key that was stuck to the roof of her locker. For the whole ride over she had been replaying Lydia's words, not wanting to forget a thing in case it was important.

And was now stood amongst the mess of Sara's apartment. Apart form the books, magazines and CD cases strewn about the floor and the kicked over coffee table, the apartment looked exactly like Cath imagined. It was stylish, warm, welcoming. It personified the side of Sara that people did not see very often, but that Catherine had glimpsed in recent months. Swallowing hard, she made the difficult journey into the bathroom. She knew that Lydia hadn't been back here yet; Sara had told her that she had not left her alone for a second. There was a blood pool on the floor, and a little bit of blood on the counter, presumably where Sara had hit her head. The blade was still submerged in the deep crimson liquid and it made Cath sick to her stomach. She left the room and gulped in the air. So much blood. It must have been heartbreaking for Lydia to find her like that.

"I held her, tried to stop the bleeding" Cath thought back to when she first arrived at the hospital, first seen Lydia. She had looked awful, but there was barely a spot of blood on her clothes. Definitely not enough for if she'd held Sara close. Of course she could have gotten changed at the hospital. Still, it was interesting.

Putting the thought to the back of her mind for the time being she made her way to the bedroom. A part of her felt wrong invading Sara's personal space like this, but she needed to know if Sara or Lydia was telling the truth. Or both. If Sara was suicidal then she needed help and they would need to know why to help her. But if she wasn't then someone had done this to her.

Catherine was startled out of her thoughts by a noise behind her. She spun around, her hand instinctively going to her hip, even though she was not carrying her weapon, and was surprised to see…

"Greg?" she sighed relieved. "What are you doing here?"

"I figured you'd come here. Thought I could help." He offered.

"Well that's sweet, but I don't know what I'm looking for." She sat on the bed. Greg was quiet for a moment.

"You don't think she did it either." Catherine looked up at him and smiled weakly.

"I don't know. The more I think about this the more it doesn't feel right." Greg nodded silently and sat next to her. "I mean, she admitted to me that she had things to deal with but she said she was talking to someone."

"Like a councillor?" Greg scrunched up his nose.

"Yeah, a friend of hers. Dan Fitzgerald." Cath sighed.

"Oh, Lucas' brother." The blonde looked up sharply, making Greg jump.

"You know him?"

"Sara and I went for a drink once, we ran into a mate of hers, Lucas Fitzgerald. Said he had a brother, I'm sure she said his name was Dan." Catherine's mind was whirring as Greg spoke…Lucas.

"Lucas! Put me down!" That's the guy Sara had been with at Scarlett Bar. Catherine leapt up eagerly, a thought forming in her mind.

"Greg, you've always wanted to get out into the field right? Now is your chance. I want you to process this apartment."

"What? I don't know how?" The lab tech frowned.

"You'll be fine, just put anything you think might be important into a separate plastic bag and take it to the lab. Wear gloves, my case is in my car. I'm borrowing yours. She handed Greg her keys and took his, running out of the apartment and climbing into Greg's car, trying to ignore the smell of cheeseburgers. Greg could handle it; after all it wasn't an official investigation. Yet, she thought.

In the meantime, she needed a drink. And she knew just the place, a retro little bar away from the Strip.

Let me know what you think x
