In personality, she is more butler-like than your typical robot – concise, staid, yet surprisingly possessed of a subtly wry sense of humour, she is an indispensable member of the crew since she can exercise control over all the ship's systems.  And she isn't shy about reminding everyone of the fact.  An outsider among the ship's human passengers, she is almost child-like in her earnest desire to fit in.  Her character will grow and evolve through her interactions with her human charges as she’ll inevitably gain acceptance as a member of the crew.
