If there were two people with an irregular sleep schedule inside the Astryd residence, that would be Sasha and Revna. As a workaholic and an overly curious researcher, Sasha spent her time in the lab poorly. Revna, for her part, was Desmond's ever-loyal and helpful shadow; she had to always be ready by his Master's side to be of help.
As part of her responsibilities, Revna also served as a liaison between Desmond and Garden; the amount of work on her shoulders was enormous. Even in her quietest moments, Revna stayed within Desmond's shadow, waiting to be needed.
It didn't take a genius to know that Revna's lifestyle was unhealthy for her state of mind, but it was hard to convince her to change her habits. The best Desmond had done so far was to need Revna's direct support so badly that she would have to spend more time out of the shadows.
