Rose Tyler was extraordinary. She had come with him for the adventure. He knew that, could see it in her eyes, wide with excitement when they left in the TARDIS. She was never shy about saying what she thought or how she felt either. And she felt...
He often wondered why he kept choosing companions. He needed no one. He was the last of his kind, wandering through time, fixing things and searching.
That was it. This Rose Tyler was what he wasn’t. She had what he lacked sometimes.
She gave him strength, more strength that he knew he had.
