It turned out they didn't have to move to L.A. Ecklie hadn't been that mad about them, he hadn't even asked one of them to change shift. He just stipulated that at work they behave like mature adults and not like high school kids in love.

The problem was, Sara Sidle felt like a High School kid. She couldn't speak for Catherine, but she really hoped that this meant she felt the same. Ecklie clearly assumed they were in a relationship, and it just felt so right to Sara. She wanted this. She wanted Cath.

Once they were out of there, Sara's head was throbbing. All of these possibilities that previously had been dismissed as pipe dreams reasserted themselves firmly in her head, and the room was spinning. She could feel herself burning up. Ever since she was a child she hadn't been able to handle big changes. They made her ill. For a week before she came to Vegas she'd had a high fever.

Something's off here. This is different.

She slammed the heel of her hand into her temple. She didn't want to think about that now. She didn't want to remember.

Her memory was right, though. The nausea, the dizziness. That wasn't right. That didn't fit. Every time something changed, all of her symptoms were exactly the same.

That was when the palpitations kicked in. Her over analytical, clinical brain said that this was textbook. She knew what this was.

Sara Sidle grimaced. It wasn't just the tachycardia, it was memories trying to surface. She put all her energy into pushing them back down. She'd deal with this later, she decided.

Her body had other ideas, though. As she realised Cat was still right next to her, talking to her, she felt her mouth begin to water.

No.

She felt her throat constrict.

Not happening.

Her stomach churn.

Anywhere but here.

Her head was spinning, and although she could see Cat talk, her words were out of sync and her face was blurred.

She opened her mouth to ask Cat to help, but before she could, she doubled over, threw up the Quorn she'd eaten only hours before, and proceeded to fall onto her side and lose consciousness.

"Lindsay was talking about this Ballet thing last night- Sara? Oh Christ, Sara! HELP! Call a fucking ambulance Greg!"

Catherine knelt down, stroking her hand through the damp brown hair.

"Sara, sweetheart, hold on." She could hear sirens. She picked up the limp body in front of her, ignoring the vomit on her cheek, and held her close.

Lowering her voice, she whispered in Sara's ear.

"I need you Sar, I really, really like you. I don't know why, but I do."

EMT Paramedics were surrounding her.

They'd taken Sara from her.

She turned, stood and ran. She reached the Ambulance just as they loaded Sara on board.

"Wait! Can I come? I'm, I'm a CSI. We work together."

The tech was about to say no, but she flashed her badge and got in anyway. As they drove away, Catherine whispered in her ear again.

"I won't leave you. I won't hurt you. I swear. I'm here, Sar."
