Claudia is a character who is defined by her need to create order out of mess and chaos and to also live life as much as possible as she lived it before she took up residence in the museum. This means that in spite of Jamie's hopes that they will sleep somewhere exciting, they choose a bed to sleep on that some famous woman was murdered on. In the same way, after a few days, Claudia insists that they go to the laundromat and wash their clothes their so that they can keep clean and tidy.
Claudia's rigorous approach to life is therefore shown throughout her time at the museum as she shows careful planning and forethought in the way that she and Jamie stow their belongings around the museuem so that if one bag is found they will still have the rest of their belongings. Claudia shows her organised and disciplined nature. Interestingly of course, she also is forced to realise how important family is through the way in which she and Jamie work so well together. She comes to see that family is very important and matures in this area of her character.
