It had been a day, and the Doctor wasn't better.

When the TARDIS gently guided Rose to the Doctor's room, she opened the door and discovered that the Doctor was already in a deep sleep. She must've passed out as soon as her head hit the pillow.

Rose immediately set to work taking care of the Doctor, climbing onto the bed to dab at her face and neck with a cold, damp flannel. After that it occurred to Rose that the Doctor would be uncomfortable in jeans and a leather jacket while she slept, so the only logical thing to do would be to change her into pyjamas.

The wardrobe was on the far side of the room from the bed. It was TARDIS blue and looked freshly painted; the TARDIS has either been preserving it or made it new for the Doctor recently. The room itself seemed freshly painted as well, a cream colour that Rose would have never associated with the Doctor. Rose had no way to know if the room had been this colour or this bare (there was nothing but a bed, a dresser, and a nightstand filling the room) before the Doctor changed or if it was for the new Doctor.

In the wardrobe, Rose found several options for pyjamas for her to choose from, and Rose sent a quiet 'thank you' to the TARDIS. She didn't quite know what the Doctor preferred when it came to sleepwear, she had never seen him in any pyjamas; when she went to sleep, he was still awake, and when she woke up, he was already prepped for their first destination of the day (or the only destination of the day when there is a lot to do) Now that he was a she, Rose knew even less of what the Doctor might like to wear.

Rose picked a long, light blue nightgown and brought it over to the Doctor. As she undressed her friend, Rose kept her eyes fully closed in respect to the Doctor's privacy. It made the job a bit harder, but Rose knew she would blush every time she met the Doctor's eyes for a week if she saw her naked body, even if it was for convenience.

After the Doctor was dressed and tucked under the blankets, Rose left the room to give her time to rest.

That was about 24 hours ago.

Rose had visited the Doctor at two hour intervals, checking her temperature with a thermometer from the med bay (and dabbing with a cold flannel if the Doctor was warm), giving the Doctor water to drink, and just keeping her company.

Between visits to the Doctor's bedroom, Rose spent her time in the library, trying to research what she can do to heal the Doctor faster. After finding nothing withing the first hour, Rose had collapsed onto the carpet, sobbing. She couldn't handle the fact that the Doctor was gone, actually gone. In the Doctor's place was just a body. A limp, lifeless body.

After she recovered from her emotional crash, Rose checked on the Doctor (her first of routine checks) and then searched more in the library, rejuvenated and intent on finding an answer.

After continuing to find absolutely nothing, about 4 hours later Rose came across a section of books with weird circular symbols decorating the spine, and recognized them from one time when she saw the Doctor write a note to himself. Well, not those symbols in particular, but it was obvious they were in the same language. These books were written by Time Lords, which means all the answers Rose needed would be right here if they were in the library at all.

Rose grabbed a book by random, not being able to read titles on the spines, and took it over the to nearest sofa to read it.

Unfortunately, she couldn't read the inside of the book any easier than the outside.

"Alright, TARDIS. You can start translatin' now," Rose called out, waiting for the writing to turn into English. There was no response.

"Nothin'?" Rose muttered, glaring at the ceiling.

Rose closed the book and returned it to the shelf, knowing that if the TARDIS was refusing to do something for Rose, it was because the Doctor forbid it. That meant even if the TARDIS wanted to, she couldn't. Not without breaking the Doctor's trust.

After that, Rose had given up the fight to continue searching, only half-heartedly looking through books that she could read, not really expecting to find anything useful.

And it was now a day.

Rose had been waiting for the Doctor to awaken for about 24 hours, and the Doctor was still in a deep sleep.

"Why didn't you tell me?"

Rose was perched at the end of the Doctor's bed, her eyes filled with tears and a cup of tea warming her hands. She was tired of playing nurse to the Doctor when this entire situation was the Doctor's fault.

"You had all that time travellin' with me. So many opportunities. So many near-death experiences, too. You could've 'ad to change at any moment and you didn't even think to warn me?" Rose's voice was shaky, so she took a few deep breaths and a sip of tea before continuing.

"The worst thing is that I can't even be angry at you. I'm so worried about you I can't be angry," she admitted, brushing a tear away. Rose leaned forward an lovingly stroked the Doctor's cheek. She gasped.

"Blimey, you're freezing. I mean, your natural body temperature is lower than mine, but you're like ice."

Rose placed her cup on the nightstand, slipping under the duvet to cuddle up next to the Doctor. Rose hoped that the Doctor would get warmer from her body heat, but was unsure of how effective that would be.

"Here, have some nice hot tea, that outta help you a bit," Rose reasoned, reaching over the Doctor for the cup of tea and then tilting the cup into the Doctor's lips.

The Doctor reflexively drank the tea, which was a good sign. Rose tilted the cup a few more times before setting it back down on the nightstand.

"There you go, Doctor."

Rose only planned on holding the Doctor in her arms long enough for her to gain some heat, but she soon fell asleep. She was exhausted from pulling an all nighter, especially after such a taxing adventure.

Rose had never slept so well in her life.
