I do not own either Doctor Who or Star Trek: The Next Generation.

Captain's Log, supplemental. After communications with the Crown and the Courage, we have been able to determine that there are 457 survivors of this catastrophe on Aetas IV. Dr. Crusher has informed me, though, that despite records and founding documents saying that the colony was only populated by humans who had moved to the planet from Earth along with a few of mixed parentage or grand-parentage, an unidentified humanoid alien was beamed aboard during the emergency evacuation attempt. The severity of his wounds may indicate that he was nearby the reaction core generator when it began to malfunction. However, it would seem that a complication in the healing process has arisen.

"Can you explain this to me once more, doctor?" Captain Picard said, sitting in a chair in Dr. Crusher's office in sickbay.

"When we first realized that he was…different, shall we say, we took readings so we'd have something to compare any fluctuations to," she began again, scrolling through the readings to show the captain. "Of course there was no way of telling if these were normal or not, but not long after I'd left Alexi to tend to his injuries, we thought we lost all life signs on him- his temperature plummeted, couldn't find his hearts beats, signs like that which you can see plummeted right about here in his charts. But when we adjusted the equipment we found that he was alive just in some sort of….comma. And since then his injuries have begun to heal at a remarkable rate."

"Could this be related to the Zalkonians in any way?" he asked, naming a race of aliens that the Enterprise had run into not too long ago. They had been experiencing changes that allowed them to heal themselves and others almost instantly- even bringing Worf back from the brink of death after his neck had been broken.

Standing from her seat to pace behind her desk, Dr. Crusher shook her head. "No, the biological make up is completely different. As far as I can tell he's fine- just in a very deep sleep. Now, you said that Deanna and Worf have been talking to the others who would have been near the ex- Whoa, whoa, whoa where do you think you're going?" she said, rushing over to the door of her office seeing the man- somehow well enough to walk and who had somehow apparently been able to get up without setting off any of the sensors- going past.

"I need to find my erhm…. My … Blimey, what the hell kind of anesthetic did you give me? Granted this turned out a lot better than the last time I got myself knocked unconscious in a hospital or medical facility of any kind but still," he said, running a through his spiked brown hair and squinting as he tried to think. "You'd think you'd think twice before giving the same medicine to someone who's clearly not human. Might look it but in all reality we were around for quite a while before you lot showed up.

"Right, ah…" Dr. Crusher said, still trying to process everything that the man had just said. Who knew that just-post-coma patients could be so talkative? Still, he was a different species, of that she had no doubts. "I'm positive that the effects will wear off once it's out of your system. But until then, you need to lie back down for your own safety," she said to him, gently guiding him back to the bed he'd been resting in.

With a huff, the man complied by getting hoisting himself up onto the bed in a sitting position. Rubbing at the back of his neck, he looked around the sickbay before focusing on something just behind Beverly. "You'd be the captain, I assume. If I'm remembering my facts correctly right now, that is."

"I am Captain Jean-Luc Picard and this is th-"

"The Enterprise," the man finished, eyes widening in something akin to shock or surprise, recognition of the names very clearly reflected on his face. "I mean I…. Blimey, the Enterprise."

"You've heard of this ship then?" he asked, moving to stand next to Dr. Crusher now.

"Of course I have. I mean I'd be surprised if you could run into anyone that doesn't know the name Enterprise- both from this ship and her namesake. Flagship of the Federation and all that. It's an honor to meet you, Captain," he continued, a large, genuine grin spreading across his features.

"I can't say I have the same pleasure of knowing who you are Mr.-?"

"Hm?" he said, quirking an eyebrow in momentary confusion. "Ah, right, yes. Sorry. I'm the Doctor."

"The Doctor? Doctor who?" Dr. Crusher repeated in a cross between concern and confusion.

"Just the Doctor," he insisted. "It's what I've gone by for…quite a long time at the very least."

"How long exactly is 'a long time'?" Captain Picard asked, wishing to figure out what this man's story was before he had to hear what the others who had been in the power station had to say. As Beverly had pointed out, Deanna and Worf were talking to them now so they could present their findings to him later, but he much preferred to hear both sides of the story first- even if this Doctor didn't actually have anything to do with what had occurred. But it was his responsibility to investigate that possibility.

"Oooh, nine centuries give or take a few years. Gets a little difficult to keep track of after a while," he said matter-of-factly with a small shrug.

The captain's next question was cut off by a voice over his comms badge, though he gave the Doctor a slightly unbelieving look.

"Worf to Captain Picard."

"Go ahead Mr. Worf," he replied.

"Captain, the two chief engineers from Aetas IV wish to speak with you. They are refusing to wait any longer."

"Understood. Have them meet me in my ready room. Please ask Counselor Troi to report to sickbay to talk to our guest. Dr. Crusher, Doctor," he said, nodding to each in turn before leaving for the bridge.

"Nine centuries?" Beverly asked once the captain had left, taking a few steps towards the Doctor. "You certainly don't look it."

"Ah, well, a slower aging process among a few other tricks," he chuckled. "This is actually the youngest I've looked in a while."

Dr. Crusher found herself smiling along with this strange man, something about his demeanor putting her at ease despite her confusion surrounding him. "Well, you certainly put the captain off guard with that statement. You did have myself and my medical team worried for a while there, though."

"Yeah, I ah… wouldn't have done that normally but the anesthetic sort of triggered that I suppose. It's just my body's way of devoting more energy to healing itself when the injuries aren't life threatening but still severe enough. Probably wasn't exactly bad enough for that to happen, but since I was asleep anyways…" the Doctor shrugged. "Guess it was triggered. Anyways, no harm done really. At least in this time my two hearts wouldn't be passed off as a double exposure and operated on because it sounded like I was fibrillating."

"Working on a starship exposes you to all sorts of biological differences. I'd be a very poor doctor if I didn't think these sorts of things possible," Beverly smiled warmly, though wondering what sort of doctor would make that assumption- especially in this day and age. "Now, Deanna- our ship's counselor- will be here soon to talk to you and I'm sure Captain Picard will have more questions for you so why don't you try to get some rest?"

"Chief Engineers Hartnell and Shatner," Captain Picard said with his customary polite smile, extending a hand to shake to each of the two men in turn before taking a seat at the conference room table. "I would have preferred our meeting to be one marked by a successful evacuation rather than the tragedy that transpired today."

"As would we, Captain," the man on the left- Hartnell- said. "We lost a lot of good men and women today- both on our engineering teams and those who were simply members of the colony."

"The investigation will take some time," the other- Shatner- said with a clear frown on his face. "But according to more than one of the members of the team that had been working on the reactor core, you have the very man that we believe to be responsible for this meltdown on board your ship."

"We do?"

"Indeed, Captain. A man who calls himself 'the Doctor.'"
