Had Rose actually seen that?
She walked to the crushed square of grass met the edge driveway where the TARDIS had been mere moments before. A very confused and intoxicated Brandon followed her. Rose sat in front of the square of grass in disbelief.
During the first two hours, Rose recounted her favorite adventures with the Doctor to Brandon.
When the third hour came, Rose began doubting everything she thought she knew about her relationship with the Doctor since their first encounter.
The fourth hour consisted of trying to help Brandon back inside, looking back every few minutes to be sure she didn't miss the TARDIS arriving, and finding and taking the Doctor's long coat back outside with her.
The fifth hour was spent wrapped up in the Doctor's coat, mentally willing the TARDIS to appear.
Rose spent the last thirty minutes trying to convince herself the night had never really happened before returning to the house to escape the cold.
