“I only take the best. I’ve got Rose.”
There might be someone new on board, but this episode belongs to Rose and the Doctor from the minute they open the TARDIS door. A few weeks ago, Rose asked the Doctor to hang back so she could take the first step into history; now the two of them step out together while their guest waits inside. This is their game. Brought together by their mutual frustration with literally everyone, Rose and Nine lean on each other, hold hands, tease mercilessly, and charge into danger. The costume designers could not have picked a better week to dress Billie Piper like a late 90s pop star. Her updo sings the song of how done she is with you. Rose asks the right questions. She won’t put up with people who aren’t interested in lending a hand. And when she doesn’t do what the Doctor says, he likes it, because nobody tells Rose Tyler not to stand up against oppression.
