Doctor Who: 10 Reasons Rose Tyler Is The Definitive NuWho Companion

4. She Dominated A Series She Wasn't Even In

You know you're a big deal when you're still being talked about after you've left. In fact, Rose was such a prominent figure in Series 3 that she was partly responsible for Martha Jones' decision to bid farewell to the Tenth Doctor at the end of it.

It didn't help matters that Martha had also fallen head over heels in love with him and he followed suit by constantly comparing her to his beloved and taking Martha to the same places he'd taken her. Seriously. Had he never heard the word "rebound"? It's no wonder Martha decided to call it a day and many wouldn't have blamed her for leaving much sooner than she eventually did. It was almost as if Rose was still aboard the TARDIS but it just affirmed how much she had meant to the Doctor and how difficult he was finding it to adjust to her sudden departure. What's more, there was already an underlying sense of rivalry between Rose and Martha which meant that viewers were hotly anticipating their long awaited physical encounter in the Series 4 finale. To say it was anticlimactic is an understatement but there was a lot going on so it was never going to take center stage. Martha was just as happy as the rest of us to learn that the Doctor had been reunited with his One True Love, though, and they were even seen hugging it out at one point in the episode so it looks like they'd managed to put their differences aside. Besides, Martha ended up marrying Mickey so she got something Rose didn't in the end. Not that Rose is particularly bothered. She had been trying to shake him off for a long time...
