Disclaimer. Don't own Doctor Who.

Quick note. I am having a hard time as to deciding who should prank who next. If you could let me know which you would prefer I can get started on chapter 9. Thanks again for the lovely reviews.

Chapter 7.

One of the many advantages of the TARDIS was that the Doctor could create any type of room he wished within its confines. If he fancied a swim, he would simply enter a few commands into the console and an Olympic sized pool would be waiting. The library he had 'installed' had the best qualities of every library in the universe. As a treat to Rose after one of their more dangerous adventures, he had created the spa room for her. Nothing too fancy, just a place for her to pamper herself and recuperate. She had gone to use the room today, leaving the perfect opportunity for the Doctor to implement his plan.

Chili powder in hand, the Doctor made his way to Rose's room. He didn't need to hurry knowing that Rose would be occupied for most of the day. The Doctor walked into the room and immediately found what he was looking for. There on her bed was the outfit she had laid out for the day.

Unbeknownst to him however, Rose had left her swimming costume in her room, and she was making her way back to get it. As she neared her room, she spotted the Doctor inside. What was he doing in there? She wondered. Slipping quickly out of sight before he noticed her, she watched him pick up the outfit she was going to wear that day and sprinkle some kind of powder on it. The Doctor then placed the clothing back onto the bed before leaving the room. When the Doctor was out of sight, Rose walked into her room to investigate further. There was no sign of powder on the clothes but then the fabric was so dark, she hadn't expected there to be. A faint smell of chili hit her nostrils suddenly and Rose was taken aback as dawning realization hit. The Doctor had put chili powder on her clothes to pay her back for the hair gel incident. Well, two can play at that game Doctor, she thought. Rose had built up quite an expansive collection of clothes over the years. Some she had bought herself, others given at Christmas and such. As a result of this, Rose often found that some of her clothes were duplicates of others. Smiling wickedly, Rose realized she had a duplicate of this outfit hanging in her wardrobe, and that by wearing the duplicate instead, she could trick the Doctor into thinking he had pranked her. Her smile growing wider, Rose closed the door and began to change.

The Doctor stood in the console room feeling quite proud of himself. He had planted the chili powder with no problems and now waited so that his prank could play out. He had landed the TARDIS on the planet Necros so that they could do some exploring. The Doctor took care to arrive in late autumn to ensure the temperature outside was a little cold. This would balance out the heat from the chili powder. Knowing that Rose would have felt them land, he waited for her to come to the console room. He didn't have to wait long as a few minutes later, she joined him in the console room. As they headed outside, the Doctor wondered how long he would have to wait before the powder kicked in.

As they walked around the city capital, Rose decided to get started on her act. Waiting until the Doctor had turned his back to talk to one of the planets inhabitants, she quickly stripped off her jacket and chucked it into a nearby bin. She had so many clothes anyway, Rose wouldn't miss the loss of one. Rose went back to looking in the shop windows as the Doctor turned back around.

The Doctor turned around to ask Rose where they should head too next only to feel his jaw drop. He had been sure she was wearing a jacket earlier, but he couldn't see any sign of it now. He couldn't tear his gaze away from her though as he took in the sight of the top she was wearing. The blood red of the tank top didn't look that special when it was on the bed but looking now, and oh was he looking, it looked utterly divine on her. Shaped to fit snugly around the curves of her upper body, his gaze was inadvertently drawn to her chest as she breathed. His breath hitched in his throat as he spotted what the cold weather was doing to that particular part of her, he was struck with a sudden primal urge to bundle her back to the TARDIS and make her his. Firmly resisting the temptation however, he fought to remember what he had been about to tell her.

This was turning out so great, she thought to herself as she observed his reaction. First he had looked a little confused, well that was to be expected as she had been wearing a jacket that was now nowhere to be seen. Then he had flicked a casual glance at her chest. A casual glance that had turned into a now obvious stare. Rose was aware of what the cool air had done to her body and she hadn't missed the way his breath had hitched in his throat when he noticed this fact. From the animalistic look he was giving her, she almost thought he wanted to devour her. Rose dismissed that notion as laughable, as he didn't feel that way about her. So as they walked together down towards the local restaurant where they would be getting some lunch, she thought about the next step of her plan.

The Doctor held Rose's chair out for her as she seated herself and was rewarded with one of her beautiful smiles. They made light conversation as they perused the menu before their waiter came to take their orders. The Doctor ordered his and asked Rose what she wanted. Her reply made his blood run cold and a sickening feeling to set about him. She had asked the waiter what they served that didn't have peppers or chili in it, for she was allergic to any foods that were hot or spicy. Oh god, oh god, oh god, panic wasstarting to set in now. He tried to keep himself calm, as he casually asked why he hadn't known she had allergies.

"I thought you did know" came her calm response, "when I was a kid mum made me chili con carne one night" she pretended to shudder and continued on. "I was ok for a couple of hours but then my temperature went through the roof, then I came up with this horrible burning rash that itched constantly. I was throwing up constantly for days."

"Oh really, that's awful" he replied whilst his mind was screaming Oh my god, what have you done you idiot. You've exposed her to a substance she is highly allergic to, and she's going to be in pain and she'll hate you and want to go home! His mind rambled on and on with each scenario getting worse and worse.

Rose meanwhile was enjoying this immensely. The Doctor seemed to be waging some kind of war with himself as to what to do now. He had broken out in a cold sweat when she had mentioned the burning rash and she could tell where that came from. The Doctor would never allow her to be in pain where he could possibly help it, and now as far as he knew that's exactly what he had done. Rose excused herself briefly so she could go to the bathroom. Once there she set to work at heating herself under the dryer. When her head was suitably hot enough, she headed back to their table trying to look as though she wasn't feeling well.

"Doctor, is it me or is it really hot in here?" She questioned him.

The Doctor glanced at her alarmed and quickly moved to feel her forehead. It was practically red hot. The Doctor knew he had to get her back to the TARDIS and fast, so abandoning their table he tugged at Rose to get her up from her seat. Luckily Rose offered no objection to his actions and walked with him back to where he could take care of her.
