Might contain spoilers as I based this story on a picture I saw on Twitter of Morgan for what I think will be episode 14x01. Not 100% sure, though, so don't get mad at me when episode 14x01 turns out to be completely different from my story! ;)
This is part 1 of 2, the second part will be added soon, I promise! :)

Panic.

It hit him every time again the very second he thought about her. It would slowly enter his body, make his heart start to beat faster and cut off his breath. She wasn't in the car… Where could she be? His heart would beat even faster and it would feel like his throat was being clenched. She had to be okay… she had to be! It would continue until the panic took complete control of his body. And then… darkness…

"Greg… Greg!"

Slowly, he opened his eyes. The first thing he saw, was Nick looking worriedly at him. "Are you okay, man?"

He pushed himself up on his elbows, realizing he was on the sofa in the breakroom. Nick was standing next to him, Sara was sitting at the table, an equally worried look on her face.

"Yeah… I think so…" He needed a moment to remember what had happened. Oh, yeah, he had fainted after a panic attack. Another one…

"Greg, we'll find her," Sara softly said. "Everyone's out looking for her right now."

"That's not good enough."

"Then what do you suggest we should do?" Nick asked him, an angry undertone in his voice. "All you've been doing since we found out Morgan's gone, is shouting at everyone else that we need to find her! You keep freaking yourself out about her, but instead of helping us find her, you tell us what we're supposed to do… while we're already doing it! Why won't you help us?"

"I want to…" The words came out of his mouth so softly he wondered if Nick had actually heard them. The older CSI nodded, though. "I figured… Then come and look at what we've found!"

"I can't…" Again, his words were barely audible.

"You can't," Nick repeated. "And why not?"

Greg turned his head away from his friend and colleague, afraid to tell him the truth now he was this angry. "Because Russell told me I can't…"

Both of his colleagues fell silent after his confession. Neither of them had known Russell had forbidden him to work on Morgan's case.

"I know how you feel about her and normally I wouldn't care, but this time I do," he had told him. "If you get wrapped up in this case, you'll end up losing your temper, just like you did when Morgan was in that helicopter and you blew up at Samantha, the guy's daughter. We can't afford any mistakes on this case, so you're staying away from everything that's evidence, you understand?"

Of course he understood, he just didn't want to understand. Damn it, he loved Morgan, he wanted to find her! The thought of losing her… Again, the panic hit him. Before Nick or Sara were able to do something, he had fainted again. This time, when he came to, only Sara was with him.

"Where's Nick?" he asked. Sara hesitated answering him, so he repeated his question, more urgent this time. She didn't look at him when she finally told him: "Russell called him. They think they've found Morgan…"

He almost jumped off the sofa. "Where?"

"Somewhere out in the desert," she reluctantly told him.

"Where, Sara? Where?"

"Greg, you're not going…" she started, but he was already out of the room. He raced through the hallways to the traffic control room, grabbing the first guy he saw by his shirt. "Where did they go?"

This time, panic hit the other guy. Splashing wildly around with his arms as if he was drowning, he pointed to his desk. Without looking, Greg grabbed the papers and raced back outside again. He barely gave himself the time to set the navigation system before pushing down on the gas. He didn't even look at his speed as he drove out of the city, he assumed every police officer in town had been warned about him already. He didn't care, all he could think about was Morgan. She had to be okay! His heart already started to beat faster and his breathing was shortened, but he ignored it. No panic attack now, he had to find her! He pushed down on the gas a little more, driving more than twice the legal speed limit now. As he had left the real city, the chances of getting involved in a car accident were a lot smaller, he told himself. And actually, he didn't even care. He had to find her!

His speed took him to his destination in record time. In the distance he saw the lights of police cars as they lit up the night sky. They moved around in circles, though, as if they couldn't find what they were looking for. Angry, he hit the brakes. Damn it! Of course they couldn't find her, this was the freaking desert! He started driving again, slower this time. The front lights of his own car danced across the sand. Suddenly, they passed over something else. He immediately hit the brakes, causing his car to slightly slip in the sand. Before it had come to a complete stop, he was already out of the car.

"Morgan!" He fell down on his knees next to her in the sand, a new panic attack hitting him. She had bruises all over her, there was a huge blood puddle next to her and all her wounds were covered with dirt and sand. His own heart was beating so fast when he checked for a pulse that he feared he was having a heart attack. He managed to take a little breath when he felt a very weak pulse.

"Stay with me, Morgan!" he told her as he got his phone out of his pocket. As soon as he heard someone answering, he shouted: "I need medical help at my location… now! I found her!"

He threw his phone down in the sand, not bothering to tell the guy even more. He just looked at Morgan, at her beautiful face, which was now a mix of black, blue and red. Carefully, he moved a strand of her hair out of the way. "Stay with me, Morgan, help is coming!"

"Greg?" He could barely hear her, her voice was even weaker than her pulse. He tried smiling at her, even though she couldn't see it through her swollen eyes. "I'm here, Morgan, I'm right here with you!"

"I love you…"

The words made his heart jump up… until he realized why she said them. Firmly, he shook his head. "Oh, no, you don't! Don't you dare tell me now! You're gonna get out of here and you're gonna be fine again, you hear me?"

"Greg…"

"No, don't even think about it! Alright, listen to me! Are you listening? You know how I feel about you and what I want to say to you now, but I won't, you hear me? I won't say it until you're all better again, understood? So if you want to hear me say those words, you're going to have to fight! You're going to survive this, you get it? I won't say it until you're better!"

If she wouldn't make it, he would never forgive himself for saying this, but right now, it was all he could think of to get her to fight for her life until help arrived. A very weak movement near his hand told her she had understood and that she wasn't going to give up now. The weakness of her movement told her help had to arrive very soon, though, or nothing he'd say would be able to save her life anymore.
