"I don't sleep." Was her simple response as she slowly sunk further and further into her chair. Too many people... 

She did mean it though. A small perk, or curse depending how you look at it, of being possessed by some god was the inability to sleep. The tradeoff was being in a constant state of exhaustion, fueling her anxiety and hindering her ability to fight off the voice in her head. 

Why did so many people take an interest in her? So many people within the past five minutes wishing to travel with her, but why? The thought of it reminded her of the last time she was with someone. They eventually tried to break her skull open to try and do some strange foreign ritual to remove the voice in her head. That was the one time Rose truly murdered someone by her own will. Wariness to travel with others partially stemmed from this experience.
