Unforgettable.
That's what Rose Tyler was.
Is.
Unforgettable.
And knowing that he will never see Rose Tyler again, never hear her laugh and see her smile.
That hurt more than anything.
The Doctor and Rose.
The Bad Wolf and the Oncoming Storm.
They were the stuff of legends.
And when he asked how long she would stay, she just said one word.
Forever.
And she will.
Just not by his side, holding his hand, running for their lives.
Never again.
But she will remain and live on.
Just in his memories.
In his hearts.
Forever.
Because if Rose Tyler is anything,
She's Unforgettable.
