The music that plays when we're first introduced to Belinda at the hospital is the same (or very very close to the same) as the music playing when we first met Rose in the shop she worked at, too. I thought Gatwa's first season was also very reminiscint of Eccleston's run, too, though! Lots of things about Ruby reminded me of Rose, with some annoying hints of Clara. Belinda gives Donna/Rose vibes in her attitude, and Martha vibes with her job and independence. So far I am liking this season better than last season, but I liked last season a lot, too. I'm just here for the ride!
