Hey guys, as mentioned over in Martian Colds (which I'm finally spelling right, thanks Kathryn :)), here is the sequel. There's a day or two gap between the two, just so you know. This first part is a very short, slightly bizarre one, but promise it'll get explained in Chapter 2 and get more fun from there ;) Enjoy!

The Doctor walked down the corridor to the kitchen, not feeling his usual bouncy self. He blamed the London food from the day before; not that he had anything against London food in general just the stuff Jack picked out and mixed together.

Traipsing into the kitchen, he gave Jack a small wave before going over and pouring himself a cup of tea.

Jack just snorted as he ate his cereal. "Isn't Halloween a few months away still?" he asked, raising an amused brow.

The Doctor just rolled his eyes at the wall. "Ha ha," he said softly, not appreciating being told he looked as ghastly as he felt, half noticing even his thoughts seemed sluggish, before making his way back out the room and towards the control room, not noticing Rose who entered the kitchen just after he left.

Jack openly laughed this time. "Seriously, what are you two up to?" he asked her.

"What are you on about?" she asked, feeling more fill of energy than she normally did at this time of morning as she bounded over to the cupboards and got her cereal before sitting across from him, giving him her usual charming smile.

Rather than return it like he normally did though, he frowned at her. "You're not playing around are you?"

"Playing wha'?" she asked around her mouthful of food.

He looked almost scared as he held up his hands in partial surrender before asking, "Rose?"

"Why is it always me that has to apologize? He said just as many nasty things as I did yesterday and I don't see you bugging him about apologizing to me!" she grumbled, stabbing out her next spoonful with more force than necessary.

"Oh boy," Jack sighed, running a hand through his hair.

Looking up, she frowned at him. "What?"

"You uh…you haven't looked in a mirror this morning have you?" he asked.

"Do I look that bad?" she asked, putting a hand to her hair. "My hair!" she screeched, feeling it with both hands now. "What the hell have you two done?" she asked, getting up and heading towards the bathroom, but Jack was up and holding her back before she left the room.

"Doctor! There's something you both need to see!" he called out, holding Rose at bay until the Doctor arrived at the doorway.

They stared at each other, both jaws dropping, both looking horrified and just a bit worried to the point of petrified.

Their outfits weren't out of the ordinary for either of them. The Doctor wore his usual brown-pinstripe suit while Rose wore jeans and a long, tight shirt.

Unfortunately there was one crucial difference in their usual appearance, which Rose had inadvertently discovered but had yet to see. It wasn't just her hair that was different, but her entire body for she now looked, and in fact body-wise was the Doctor, and the Doctor was Rose Tyler.

And now the name of it makes sense right? Decided since I always update on Saturdays, it's only fair that made it in, and calling it Freaky Friday just felt waaay to cliché :p Anyway, hope you liked this little intro. More to come next week :)
