If I am following a person and they are starring or guest starring in an episode, it would be helpful to make the episode show up in my calendar even if I'm not following the show itself. I know that guest stars are usually not added until after an episode airs but it would still be helpful for those cases when guest stars are added in advance. Or I happened to look back in my calendar and see an episode of something that I may want to see after it airs. If the person is part of the starring cast, perhaps show all episodes in the first season and only episodes where that cast member is active in successive seasons.
