"Doctor!?" Sarah Jane gasped and knelt over the still form of the time lord. "Doctor? can you hear me? Doctor?" She tried to shake him, and gently slapped at his face, but he did not rouse. "Luke, what happened?"

"I-I don't know, mum! I was just walking home from school, and I saw this taxi blazing away so I thought something was wrong. I came up the walk, and found him here! Is he alright, mum? I mean...is he…"

"He's alive, it seems...I don't understand this! What's happened to him!? Why did he come here? Where's Rose?" She shrugged away the questions of panic and switched into a mode of concentration and action. "Alright now, help me get him inside. We can't exactly leave him here in the doorway! Come on Luke."

"Right mum." He tossed his backpack aside and gently took up the Doctor's feet, while Sarah Jane lifted his torso. They stumbled back into the house and made their way to the nearby living room, where the placed him, as gently as possible, on a couch.

Sarah Jane's watch kept beeping, reporting alien life nearby, but she knew what, or rather who, that alien was, so she turned it off. Suddenly, a quiet whirring noise could be heard as the faithful robotic companion to both Sarah Jane and the Doctor came around the corner.

"I know K-9! It's-" She began, but he interrupted, when he reached the couch.

"Yes, K-9? Can you tell me if he's alright? How is his physical status?" She knelt between the couch and her dog, and placed a hand on the Doctor's hand, and the other on K-9.

"PULSE READING: SLOW….ONE HEART FAILING…. RESPIRATION: SLOW...TRACES OF EXTRA ALIEN LIFE SIGNS INTERNALLY...PROCESSING...PROCESSING… IN-HABITATION OF EMOTIREL LIFE FORMS… AND…." K-9 paused as if confused by the data.

"K-9? And what? What else? What is it! Access the data!"

"AND….BODY SYSTEMS FAILING...MASTER IS….IS…" K-9 again paused and his ears began twitching as if he were nervous.

"What is it K-9? What's wrong with you? You act as if you couldn't say something because of emotions, but your system doesn't process emotions in the same way...your purpose is to provide information, and that is what you must do. Now, what is it K-9. Tell me. The Doctor is, what?" Sarah Jane scolded the metal dog.
