Watching Downton Abbey, I understand that it's a bit more practical to have all the drama happen with the senior staff, but I've always thought it might be neat if we saw some of the junior staff partaking in the drama. Like what if there was a housemaid who decided to make an ally of Thomas, and ended up outfoxing him every so often? Or maybe a pair of hall boys who try to charm treats from Daisy? Whatever the case, I'm sure it'd make an interesting arc.
I kind of want to see what the junior servants think, because I feel it would bring in characters who are growing up in the time of the Great War, maybe having lost a brother or father at a young age because of it, or growing up in a shifting political landscape. It would also have the potential to bring out different aspects of the main downstairs characters that we might not see otherwise.
Just a thought.
