Warning: MAJOR spoilers ahead for The Diplomat season 2.After being introduced in The Diplomat season 1, Celia Imrie’s Margaret Roylin plays an even bigger part in the latest run of the Netflix political drama, and her arc is very different from the previous run. Imrie is a major part of The Diplomat season 2 cast, as most of the story can’t progress without Roylin’s involvement. However, she lacks the freedom she had in The Diplomat season 1. Regardless, that doesn’t stop her being a huge part of the plot.
