From the moment they landed, it was all go. Rose was astonished at how quickly The Doctor was sped away from her and whisked off into the building, to be transported to a medical suite. Clearly Torchwood had been well prepared for their arrival. Jackie kept her arms wrapped tightly around Rose, but when Pete rushed over to greet them, the both fell into his arms and the family embraced. The wind was choppy though, so they didn't stay there long, before moving under shelter.

"I've got Tony with a babysitter", he says as they walk inside.

"I should hope so", responds Jackie "The last thing that boy needs is to be hanging around Torchwood where he can get up to lord knows what."
Rose remained silent, with her head down. Wanting to comfort his adopted daughter, Pete Tyler found a blanket to wrap around her, while she waits on a cold couch in the corridor outside The Doctor's room, for any news.

"He's getting the best care possible, love", he tells her.

"I know", she says.

Time passes ever so slowly and yet the whole world seems to be rushing around her and she is caught up in the middle of it. She knows her mother had said something about tea, before bustling off. Her mind desperately tries to sort out the events for the past few days. Never did she expect she would have to be struggling on this long.

"You should get some rest", Pete tells her, placing a hand, over both of hers, where they rest in her lap.

"Not until I've seen him", she insists.

Pete wants to argue. He can see the layers of exhaustion threatening to overwhelm the girl, but he knows very well, that Rose will fight until she gets what she wants.

"I'll see what I can do", he says, leaving her.

Sometime later, Dr Owen Harper, one of Torchwood's medical operatives exits The Doctor's room, clipboard in hand. In a flash Rose was on her feet and craning her neck to catch a glimpse of the part-Time Lord, but Owen has shut the door, before Rose can see anything behind him.

"We've got him stabilized Rose", he stated at seeing her apprehensiveness. "But we don't know what's wrong with him. I need to ask you some questions about The Doctor, okay? Just sit down for now" Rose wants so badly to just ignore Owen and burst into that room, but she refrains and sits down. "Good. Now, tell me exactly what happened, from the beginning."

"There was this, well The Doctor called it a 'meta-crisis' or something. He's only got one heart", she spluttered.

Owen had made to jot down her words, but cuts in "Hang on, slow down. Explain yourself. How many hearts is he supposed to have?"

"Two"

"Blimey. Okay, what happened to the other one then?"

"Nothing, this Doctor's always had one heart. It was the other one, the Time Lord one-"

"Rose, you're going to need to backtrack, just a bit more for me on this one. You're not making sense."

Taking a deep breath, Rose tried again. "Yes, alright, The Doctor was dying, right?" Owen has his pen at the ready, tongue between his teeth, nodding to coax her along. "Well, he does this thing when he is about to die, called regeneration. Basically, he changes, his face, his whole body, everything." She begins to explain. "Except he's the same man", she chooses to emphasize.
Owen continues to nod and Rose knows he is doing his best to understand. It is vital he understands everything if they're going to help him. He's the man with the medical knowledge after all.
"Only this time, it went a bit different. You see, when he had last regenerated, it went a bit wrong, and he was passed out. Tea helped him though –got him awake again. Afterward though, he lost his hand in a fight. It got cut off, but he was still regenerating at the time and was able to grow another one. The next time he regenerated, he had this hand spare right, so he didn't have to regenerate all the way. He sort of used the hand to channel his energy and still look the same. Then he was alright."

Owen frowned, when Rose paused and said, "That's amazing and all, but he's clearly not alright just now, so I'm guessing there's more to it."

"The Doctor had this friend called Donna", spoke Rose. "She's human. The spare hand still had all this Time Lord energy in it and Donna, she touched it, got her own DNA all mixed up and it triggered something. The hand grew into a clone of The Doctor -except he wasn't exactly the same. This Doctor only has the one heart. He's part human, with one life. He can die. He seemed fine though, healthy in fact, until a little while after we got dropped back into this universe and that's when he collapsed." Rose's shoulders dropped. It felt good to let out some of the events she had just been through.

"That's great, Rose. You've done really well", Owen wasn't being patronizing. He understood Rose had been through hell and back the past while and any Doctor could clearly tell she was in no fit state to be pushed just now.
He did wish she would at least sleep, but knew better than to ask it of her. It was unlikely she would rest until she got some peace of mind, involving The Doctor. She would have to see him with her own eyes and know that things were being done to make him better.
"His heartbeat is still extremely elevated, so we're watching him closely. This could have to do with the fact that his body is used to functioning with a binary-vascular system and it's trying to compensate. We can fix that, alright.
I'm worried about his temperature too. We have to be careful that his brain doesn't cook.
What I plan to do next is run some standard tests. We are not about to do anything invasive, without getting a thorough understanding of his physiology, what parts are where and what drugs are safe to use on him.
As far as I can see, we're working from scratch. We don't know how much of him is human or how much is Time Lord, so we have to work that out. At the moment though, it looks like his brain isn't too sure on this matter either. It may be a simple matter of giving him time to adjust."
Rose took this all under consideration, but was perched on the edge of her seat. She wasn't going to stay there much longer.
"Come with me", said Owen, presenting an arm to pull her to her feet and lead her through to The Doctor.
