Rose burned.
Before her, she saw the awed, terrified eyes of her Doctor...but she also saw so much more than that.
She saw everything; all that was, is, and ever could be.
She saw a year of happiness and adventure ahead with her Doctor...but what she saw after that, she did not like at all.
A white wall, pain, tears, and above all, despair.
Sadness ripped through Rose, the vessel of the Bad Wolf...she could not leave her Doctor, not like that.
But even as the Bad Wolf, she would not change it. It was fixed. Rose mentally cried out at this, but the Bad Wolf, the power of Time, soothed her; there was nothing fixed about her return. A million possibilities, all swimming in front of them...
The Bad Wolf smiled, and with a flick of her hand she fixed the future of her host and her Time Lord.
Rose burned...and thousands of years and miles away, another girl burned with her.
