Sam sat in the corner of her quarters staring blankly at the opposite corner. Her hands were shaking and she glanced at the thin shivering hands. She hadn't eaten in over a week but somehow she didn't feel hungry. She knew she had to eat but her stomach rejected everything she swallowed. Her skin was pale and she looked like she hadn't left the dark in months. She had though. She had been off world to the place where this must have started. She could remember crossing a small river through the water with the rest of sg1. She had felt something sting her lower back, it was very soft and hardly noticeable but she noticed. She had felt a wave of nausea the instant she was stung and felt uneasy about it. She told Janet about it but Janet checked her out and she was fine, nothing was different and there was no mark on her back and no symptoms aside from the loss of appetite. The symptoms she felt now had only arisen early this morning. She was typing away at her laptop when she had felt a sudden throbbing in her head like an intense migraine. She had tried to ignore it but the throbbing wouldn't leave and so she got up to go to the infirmary when her legs went numb and her feet rolled over themselves as she tried to walk. She had collapsed. She lay on the floor and stared up at the roof. The light had brightened all of a sudden and she had found herself squinting to keep from going blind. She had dragged her limp legs over to the light switch and had reached up to switch it off. Then she had crawled into the corner and sat staring blankly at the opposite corner. She had been sitting in the corner ever since. In the darkness her vision was perfect. She felt as though her eyes now had a night vision mode, only she didn't see in green or red. Everything she saw had a heightened colour tone. Her blue air force issue uniform pants were now a much more vibrant colour like the rich blue of primary blue paint. The silver in her watched gleamed out brightly as though it were glow-in-the-dark. She heard a harsh bang on the door. It was really a light knock but her senses were unnervingly heightened. She panicked she wasn't sure what to do. After a while she just called for the knocker to enter but to her surprise nothing came out. Her voice was gone, she tried screaming but no noise was heard. All that could be heard was the faint gargling of her struggling throat. A moment later the door eased open and she shielded her eyes from the blinding light.

"Carter?" Jack asked flicking the light on "we kinda missed you in the briefing" he said as he saw her in the corner "are you alright?" he asked as he noticed her cringing at the light and holding her throbbing head in her hands. He could see the pale white of her skin and how she was shivering. He walked over to her side and knelt down to her level. He turned her face to see her. Her lips were blue and the once innocent blue of her eyes was now a deep blood red.

'Shit' she heard him but she watched his lips and they hadn't moved. He had cursed and she had heard it but Jack hadn't spoken. Jack had thought it and she had heard it.
