Author's Note: And to the answer of the question of where this story fits on the Doctor Who time line, I was thinking it to be after Martha but before Donna. That way I don't have to worry about the planets in the sky, stuff.

"What the heck?" exclaimed Henry, staring at the computer screen.

"What is it?" said Kate, leaning in behind him.

Together they watched the illustration of the protection field grow steadily brighter and brighter.

"What's going on?" questioned Kate.

"No idea. I'm trying to stop it, but it's like something or someone is controlling it," answered Henry, typing on the keyboard, trying desperately to gain power again.

"What would do that?"

"Again, no idea."

Suddenly the electricity went out. The lights shut off and the computer screens went black. The only light now came from outside as it filtered into the Sanctuary through the windows.

"No. No! NO!" cried out Henry, slamming the keys before throwing his hands in the air in frustrated defeat.

"What? What happened?" quizzed Kate.

"The power's out," said Henry with a sigh. "The backup seems to be working, so the abnormal are safe."

"Yeah, guessed that since the lights went out. But why did the power go out?"

"The protection field blew out the system."

"But isn't there anything you could do to fix it?"

"Yeah, but it might take awhile," answered Henry, rubbing his eyes with the balls of his hands. "Even if I get it running back up again, we still have to find out what caused it. Whatever or whoever is doing this might try it again."

"Well, then let's get started," commanded Kate.

~***~

Will was shocked, to say the least. That couldn't be true, could it? Time travel couldn't possibly be possible, right? Yet, there was no other explanation. This man, this 'Doctor' had be everywhere in history it seemed, all though he didn't look hundreds of year old. That Police Box must be his time machine, thought Will. That was why it appeared out of nowhere. But despite the facts, Will had a hard time realizing that that was the reason this man was able to do all those things.

But before Will could say anything in response, the lights went out. Magnus and the Doctor immediately stood up and looked around, trying to figure out what happened.

"Power's out," muttered the Doctor.

"But how? Henry usually has things running smoothly. We haven't had a power outage in years," commented Magnus. "Will, try his cell."

Following his boss's orders, he took out his cell and started to dial Henry's number. His head was still swimming about the fact that the man standing next to him was a time traveler like something out of sci-fi books. It just didn't seem possible to him. But he put that out of his mind for time being, as he focused on what was happening now. After a few rings Henry picked up.

"Yep, what is it?" answered Henry.

"Power's out," replied Will, stating the obvious.

"Could you put it on speaker?" asked Magnus.

Will did so, taking the phone away from his ear, right at Henry was responding.

"Yah, working on that."

"Henry, what happened?" questioned Magnus.

"The protection field overloaded the system, causing the power outage."

"But how? At a normal rate, the field can't possibly do that."

"I know, but its power was increasing for some reason, and it finally got so large that the system couldn't handle it."

"But that doesn't make sense. How could the power be increasing?" interjected in Will.

"I don't know, but it might have to do with something the fluctuations that were happening before," responded Henry, the sound typing keys in the background.

"Hold on. My uh…blue box was doing that," piped up the Doctor. "But I fixed that. It can't be what caused the power surge."

You mean your time machine was doing that, thought Will. But then he shook his head. He couldn't be pondering the possibility of time travel at a time like this. He had other things to work on.

"Wait, who are you?" quizzed Henry.

"He's the Doctor. The Police Box outside is his. Now could we please get back on topic?" stated Magnus.

"Of course. But, Doctor, how can you be sure that your box is not the cause of the power overload?" asked Henry, his voice coming from the phone.

"Because I would know," answered the Doctor, scratching the back of his head. "It's complicated, so don't ask me to explain."

"Okay, then what could be the power surge? Magnus, is there any abnormal that could do that? Maybe one of them got lose," suggested Will.

"We would've been notified if one escaped, and it would be impossible for one to get on to the grounds," answered Magnus.

"But when…that blue box of his got on to the grounds the protection field was off. Could it have gotten into the Sanctuary at that time?"

"No. Those abnormal are very rare and can be extremely dangerous. The Sanctuary knows where every one of them is in the world. I would've been contacted if one was in the area."

"Maybe it was one that you didn't know about?" tried Will.

"I'm sorry Will but that's nearly impossible. Unless there's some other abnormal that I don't know about, which again is almost impossible," said Magnus.

"Nothing's impossible," muttered the Doctor, head turned away with eyes looking off in the distance, brain obviously in thought.

What does he mean by that? thought Will, looking at the strange man with a questioning eye. Suddenly the Doctor popped out of his trance and turned back to the phone that Will was holding in the middle.

"Uh…What's his name?" asked Doctor looking at Magnus.

"Henry," replied Will.

"Right…Henry, when exactly did the protection field start to increase in power?" quizzed the Doctor.

There was a muffling on the other end, but a few seconds later, Henry's voice was back on the line.

"About 20 minutes after your blue box appeared."

"'20 minutes'" quietly repeated the Doctor, looking up and staring at the wall across from him. "Was there anything else that was acting out of the norm?"

"No, it was only the protection field."

"And is the protection field online now that the power's out?"

There was a silence on the other end as Henry stopped working. Apparently Henry didn't think of that, thought Will. That can't be a good sign.

"Crap! No, it's not," exclaimed Henry, who now seemed to be typing and working faster.

"Henry, get the power on as soon as possible. Will, the Doctor and I will be trying to figure out what caused that power surge," stated Magnus.

"Right, boss."

And with those final sentences, the line on the other end went dead and the phone went silent. Will put his cell into his pocket and looked up at his boss and the Doctor.

"So if it wasn't an abnormal, what else could it be?" questioned Will.

"Well," began the Doctor, turning away and starting to pace. "It could be any number of things. Interference from a ship close to Earth, or an energy wave from something like…let's say a intergalactic ripper, or even something as simple as a concentrated blast of solar radiation. But I can't say for sure. I only got a reading of a portion of your protection field when I was trying to fix the fluctuations before. Do you know anyone that would want to knock out your protection field?"

"Yes, there's quite a lot. But none that I know of could've been able to do that to our field. It is very complicated technology, and Henry put so many precautions in the system that it's almost impossible to hack it," answered Magnus.

"Unless, it's something or someone that has the technology to do that. But why would they want to get into the Sanctuary?"

"And who or what could have that technology?" questioned Will.

"Well, creatures not really from here," answered the Doctor. He had stopped his pacing, and turned to look at Will and Magnus.

"What do you mean by that?" asked Will, totally confused.

"Well," began the Doctor pivoting on his heel and turning away from Will and his boss. "You would call them…aliens."

"'Aliens'?" repeated Will in disbelief.

First time machines and now aliens, this day was getting weirder and weirder and even more unbelievable by the moment.

"Yep," spoke the Doctor, spinning back to two hands in his pockets and looking at their reactions.

"Aliens? Okay you can't be serious," responded Will.

"It does sound a little mind-boggling…but for some reason it makes sense," interjected Magnus.

"Come on Magnus, isn't that a little far-fetched. I mean aliens taking down the Sanctuary's protection field? Doesn't that sound more like a science-fiction story than truth?" replied Will, wondering how his boss could possibly be pondering the existence of aliens.

However, the more Will thought about it, the more it seemed plausible. There was all the weird stuff that was happening in the UK. But that was all just mass-hallucinations and stuff like that, wasn't it?

"Well, I wouldn't say 'far-fetched' exactly. You've meet some. I think some are even here in this building," said the Doctor, talking quickly.

"Are you saying that some of my abnormals are aliens?" quizzed Magnus questioningly.

"I'm just saying that some creatures in this building aren't exactly made by Mother Nature, if you know what I mean."

"No. I don't know what you'd mean," replied Magnus firmly.

"That doesn't really matter right now," started the Doctor, sounding uncomfortable and turning way again. "What matters right now is what overpowered your protection field."
