I agree that this series conclusion was pretty rough, although not quite as far-reaching as last series'. Interestingly, as tragic as Lavinia's sudden death was, it was not as effective on me. Maybe that's because I suspected all along something would happen to her. For my part, it was Matthew's crushing realization at what Lavinia had seen/overheard. The guilt he felt ... that's a burden almost incalculable in its power.
