Set just after The Girl in the Fireplace episode, and in the middle of 6th year.
Rose was having the time of her life. Travelling with the Doctor, the only man she'd ever truly loved, going on adventures, meeting aliens, going to strange new planets and falling in love with the Universe. Sometimes it even seemed as if the Universe was falling in love with her, the way life was going for her- all the fun, just escaping, all the running (her figure had never been so good) and all the people she was meeting. Which probably meant something bad or unexpected was going to happen soon- Rose had The Feeling. Whatever The Feeling was or meant, Rose didn't like it one bit.
The Doctor loved his life. This new regeneration of his seemed to be more relaxed, less sassy (which was a downside) but was more able to love- he felt he had a whole new realm of emotions to explore- and just the companion to explore them with. Rose. The Doctor had loved Rose in his previous regeneration as well, but not in the same way as he is able to now.
The Doctor also loved the spontaneous-ness of life. He loved being able to chuck himself into the depths of the Universe and come out unscathed. The Doctor also had The Feeling. He had experienced The Feeling before, with former companion Sarah Jane Smith- but that was ages ago, 6 many regenerations ago from now.
"Allonz-y! We can't just hang around orbiting the very beautiful Crab Nebula forever, we have to go somewhere! Why don't we take all the restrictions of the TARDIS and set it to random? Be a laugh and we could literally end up anywhere!" Clearly, the Doctor was on a roll and had drunk one too many cans of Red Bull. As no alcohol was allowed on board, (the TARDIS was very particular about that, making angry noises every time they even parked outside a pub) Red Bull was the most exciting drink they could get.
"Why not!" replied Rose, revelling in the Doctors ability to be full on insane.
The TARDIS plunged into the time vortex, spinning and whirling while the inside stayed perfectly calm. "I've fixed the thingamajig which was hanging off the doodah" explained the Doctor "allowed the TARDIS to remain perfectly still on the inside even if there's a hurricane on the outside."
Rose wasn't complaining, she has thrown up one too many times as a result of the TARDIS, so she was glad to have the TARDIS 'sailing' through time and space without dislodging her entire abdomen.
"And…. We've landed!" exclaimed the Doctor, and turned to give Rose a joyful hug.
After the quick embrace, they spun around towards the door, ready to step out into the unknown planet that waited; when they turned to face three of the most panic stricken confused teenagers which had literally just appeared out of nowhere.
These teenagers were dressed in black robes, and were of course our favourite trio Harry, Ron and Hermione.
