Normally, Anna is a reserved person who doesn't say much unless needed or spoken to. This changes when she is alone with Roland, or when they are talking about science. She becomes very talkative and lively, almost as if she was another person.
Anna is straightforward to a fault. She doesn't like beating around the bush and goes straight to the heart of the matter in conversations.
Anna is a studious and genius person, who enjoys to learn new things; Karl noted that in his class she would always have more questions. As she learn more from Roland, her thirst for knowledge only increases. Roland also noticed that she almost always has a book on hand to read.
Anna is also a bit shy. This is shown when she says she isn't comfortable with showing acts of affection with Roland in public.
She fullheartedly accepts inventions Roland produces, always trusting good intentions are behind them. Anna even helps an apprehensive and embarrassed Nightingale understand the new "garment" Roland had made for the older witches was out of concern and not some kind of perverse idea.
It is hinted Anna shared almost the same amount of IQ as Tilly.
