Disclaimer: I totally wish I owned CSI but I don't. :(

Set in season 10 or 11... No real time line but a fair amount of time after Riley left.

Familiar Faces.

Back Up.

Greg was driving to his next case when his radio crackled. He was expecting a simple police alert but was surprised by what he heard on the other end.

"This is CSI Catherine Willows requesting back up at 368 Eden street. Repeat, I need back up, police units and CSIs."

Greg looked down in shock. He knew she would be pissed if he didn't go to his case but he was gonna go help whether she liked it or not. He wasn't having a repeat of the Ray and Riley incident. The thought of Riley's name made his heart skip a beat. When she left it had hurt. A lot. She didn't even say goodbye.

Greg turned at the next intersection and flicked on his police lights. He sped towards the scene,all the while hoping that nothing was wrong.

Riley groggily opened her eyes to darkness. She tried to move but was stopped when she realized she was tied up firmly. Her arms were behind her back and she could barely feel them, let alone move them.

She was lying on a wooden floor, that much she could tell. She felt something wet on her leg and instantly regretted it, when she tried to flex it. A searing pain shot through her calf and she finally realized that there was a large wound on it.

Most of all, she was confused. Last thing she remembered she had been in a warehouse on the outskirts of Illinois with her police team. There was a flash of light and then nothing. She had no idea where she was now.

She felt like she had been unconscious for a long time. Riley wasn't one to worry, but in this particular situation she felt her heart rate increase. Nobody knew where she was. Including her. She hadn't been this worried since... well, since she and her former co-worker Ray, had been held hostage. She didn't want to think back to those times, but she couldn't help it. She had just up and left. And boy, did she feel bad. She knew it probably hurt the team. Especially Greg. Riley felt a pain in her heart as she thought of him. He had been an amazing friend to her and she knew she had hurt him more than she had hurt anyone else. She couldn't even bring herself to call him.

Riley sighed and tried to loosen the duct tape on her wrists. Of course it didn't come off. She tried her feet, ignoring the excruciating pain in her calf, but that didn't work either.

She was in a closet and she was beginning to feel helpless. What if her abductor had left her here? She had seen too many dead hostages and kidnapping victims in her line of work. She just needed help. She thought about calling out, but realized that if her abductor was still here, he would probably get angry. And the one thing you don't want to do when being kidnapped, is make your assailant angry.

Riley felt dizzy when she tried to move her head. She had obviously been drugged and even though it had partially worn off, she could still feel the effects.

But just then she heard a voice in the distance and she held her breath, listening as hard as she could.

Uh oh, whats gonna happen? Review pleaseeeee
