Of course, it's not compulsory to watch from the beginning but when you get to series 4, I think it does helps to understand the long relationship between Birgitte and Katrine - from tough political interviewer to Birgitte's New Democrats campaign manager and then departmental head of news at TV 1 - and how she became involved with Lars Mikkelsen. It helps to understand why Birgitte's son Magnus hates Laugesen so much and how moderate Bent Sejrø, now in decine, was so influential in helping Birgitte shape her political beliefs and early career campaigns. She always sought his advice in troubled times.
