Rose having the whole "damn I just ran off with some man I know nothing about to SPACE" crisis is something so overlooked imo. She remains an extremely complex character and despite being the most popular NuWho companion, I believe she is underrated when it comes to her writing. Rewatching this show is like living a whole different experience, knowing what will happen and what happened. Nine's reactions to the mention of home and the war makes my heart break into a million pieces. On the other hand, just an awesomely written, iconic episode. Toxic by Britney you will always be famous.
