The medbay was once Sophia's constant companion. Especially in her previous life. Yet she never felt aversion to it in the current one. Whenever she felt too tired, she would slip into medbay to occupy vacant cocoon. It might be the hi tech support, soothing lighting or the tranquil background music, on the days she could not sleep, she came to medbay in the sly. The department people got selective blindness whenever she came in such way.
Today, Sophia felt tired. Tired to the level of soul. No need to go through backgates. She was tired enough to warrant a nap in the cocoon.
The last thing she did before slipping into deep sleep was to call Kara to co-ordinate with the security. The world painted her as a cleaner. Let's indulge their fantasy.
