honestly the power and influence of billie piper playing rose tyler. she had both chris eccleston and david tennant wrapped around her finger. her chemistry with both of them is to this day insane. the other actors in doctor who long after her bring her up in conversation and she continues to be brought up in the show. on a zoom reunion, she was snatched up as ‘companion you’d want to travel with’ instantly. she’s an ordinary girl but there’s no one like her. her arc is so good that they regularly try to recreate or deconstruct it. some of the episodes she’s in are terrible but it doesn’t matter. the doctor loves her so much it both saved him and killed him. multiple times. she lives rent free in every doctor who fan’s mind. love her, hate her, or indifferent to her, she’s the basis for comparison. she’s at the tip of the tongue of people who gush about the show and people who complain. billie piper still affirms her unpopular (correct) opinions about rose and the doctor. she was the consistency, the heart, and she redefined the entire fandom.
