Maid and Cook for the Hotel Dusk, Rosa has her work cut out for her. Between Louis' shenanigans and Dunning's hockey games, she usually ends up doing a lot of what needs to be done. She also has a husband and son, though she has seen neither recently.
With an assertive and independent attitude, she does fairly well for herself. She also has a good sense about what people are about, relying on her intuitive skills. When she gets a few moments to herself, she likes reading her favorite Martin Summer novel.
