Chapter One- Sickness or Emotion

Scott Tracy sighed wearily as he entered the lounge room covered in mud. He had just come home from a mudslide that suffered lots of fatalities. Maybe that was why he was feeling sick to his stomach.

"Ah, Scott," said Jeff. He was seated behind his desk, and he was waiting for Virgil and Alan to come back from the rescue. "Have a seat. The others have just landed and are completing post flight checks, so as soon as they come to the lounge, we can start on the debriefing." Jeff's head immediately returned to a pile of paperwork that was situated on his desk.

Scott sank down onto a chair and leant back. A sharp pain shot through his abdomen. He muttered a curse under his breath and leant forward to relieve some of the pain.

Upon hearing the curse, Jeff looked up.

"Is anything wrong, Scott?" Jeff asked. Scott shook his head grimly, trying to mask the pained expression on his face, but failing. Jeff could see that there was something wrong with Scott, but he thought that the deaths in the rescue had upset him.

At that moment, Virgil and Alan Tracy entered the lounge. The flopped unceremoniously onto the sofa, on either side of Scott and the debrief began.

Two hours later, the Tracy brothers had showered and changed out of their uniform. They were relaxing until Kyrano called them for dinner. Vigil, Alan and Gordon all ran out off the room, eagerly anticipating the feast that lay on the table. Scott, however, trudged slowly towards the dining room table. He really didn't feel like eating. All he wanted to do was to lie down and go to sleep. But he couldn't. Scott hesitated, before he sat down on his chair, placed his hands on his abdomen, and leant slightly forward. Jeff noticed his eldest's son hesitate before he sat down and started to worry about him.

"Son, are you sure you're alright?" Jeff questioned, looking Scott straight in his crystal blue eyes.

"I'm fine, Dad, just tired." Scott stared straight back at Jeff. Jeff noted the pain, hurt and a hint of fear in Scott's eyes.

"Would you like to go to sleep?"

Scott nodded his head in response to the question as another jolt of pain shot through his abdomen.

"Off you go, Scott. I'll see you in the morning."

Scott stood up, and walked out of the room, his hands still on his abdomen.

AN: Reviews would be nice- constructive criticism is OK, but nothing nasty please. I will try and update this as soon as possible because I am being flooded with homework. This is my first fanfic so please be nice!
