Ingrid is the young pregnant girl bitten in the opening cutscene. Her husband plays a supporting role and may be referenced/included in some conversations, particularly later in the game. She is a fairly central character early on, so if we need a new head, she should be blond, with shoulder length hair, and aged around 19. She would be considered quite pretty, and has an open and expressive face to match her optimistic outlook on life.
Young and optimistic, but fearful of the future. She has an eager nature, and is easily excited. At first, she has the optimism of youth; 'this isn't really happening' mentality. As the module plays out and Ingrid gets nearer to term, she becomes more despondent and fatalistic.
