==== ==== Harry Sullivan ==== ====

Back in the Surgeon Lieutenant's office, Harry was just filing away the latest report on the Doctor's health. It felt quite strange to mix into the failed analysis of blood samples and oddest of measurements one list of results that was so different by just being normal… Had the Doctor not recognized him and Sarah, the young medical officer might have been tempted to doubt the man's identity. But just how could a Time Lord turn into a human? Harry had already told Sarah that he had no clue. In fact, he could not even begin to imagine how anyone would survive a fundamental change in physical structure like that. And even if it was possible – somehow – it had to be both extremely dangerous and painful! Although he hoped for the sake of his friend that there was a way to revert the process, he was not very optimistic about it. Unless the Doctor remembered the scientific details himself to teach them to someone, the former Time Lord really might be bound to stay human for the rest of his now, comparatively short, life.

Harry hung his lab coat on a hook and sat down in his office chair to ponder about the matter a while longer. Just today, the Brigadier had left for Geneva and he found that he was rather glad not to have to explain the matter to his superior just yet. It might even be better if the knowledge remained with Harry, Sarah and the Brigadier only. The Doctor's enemies on Earth – especially the Master – would better not know of his vulnerable state. Sarah had not been so wrong after all; Now Harry found himself thinking about how useful it was for the Doctor to be a good bit tougher than your average human when it came to finding oneself in tight spots.

Suddenly – because it only ever happened suddenly – there was a knock on the door. When Harry called for the stranger to enter, the door was already opening. In came Benton, who as usual, was smiling as he greeted the medical officer.
"Hello, Mr Sullivan."

"Hello, Benton.", Harry replied friendly. "What can I do for you?"

The Warrant Officer walked up to the other side of Harry's desk. "I've heard through the grapevine that you've been out investigating with the Doctor and Miss Smith, is that right?"

"Yes, that's right, Benton. They're both well… considering.", Harry replied hesitantly, careful not too spill too much this time. Whatever Benton knew would spread twice as fast through the so-called grapevine.

The soldier looked at him confused. "Eh? Considering what?"

"Considering his loss of identity. He doesn't seem to remember his involvement with UNIT and... all that." It wasn't quite true, obviously, but Harry was far from the right mood to explain it all in detail at the moment. So he rather kept it vague and spared himself of too many questions.

"Oh." Benton's smile faded and he looked almost disappointed now. For him, it was probably a privilege that an extraordinary being such as the Doctor knew his name… had known his name. "How did that happen?", he naturally wanted to know.

"We don't know. Not yet, anyway.", replied Harry.

"Well, if there's anything I could help with, you know, I'd be glad to lend a hand." Judging by Benton's smile he would have been happy to do just about anything. Maybe he had too much time to spare at the moment...

"No offence, Benton, but if I need assistance I would rather ask the Brig first. He knows best what to do.", the medical officer excused himself. After all, the hierarchical structures at UNIT were there for a good reason. "But thank you, anyway."

"You're probably right about that." Benton nodded approvingly. "By the way, Sullivan… I've also heard that you were looking for a mirror?"

"In a sense, yes... we were attacked and the mirror was stolen." Harry looked at him a little surprised at how much information had already spread. "Why are you asking?"

"I just remembered and thought I should let you know; There was this huge mirror in the office of the weapon manufacturer who disappeared three weeks ago or so.", explained Benton and shrugged, uncertain of the facts he was presenting. "We packed a couple of things for further investigation and I believe that the mirror was among them. They have brought it into storage room A-12, if I'm not mistaken."

Harry frowned at him. Could it really be that mirrors had something to do with these cases? After all, there was nothing scientifically unexplained about mirrors: Glass, a shiny surface and a frame. The only thing which suggested that something was out of order was the fact that someone had knocked out the Doctor just to prevent the mirror's discovery. "...Was there something unusual about it?", he asked after a little while of pondering about the meaning of this information.

Benton's apologetic smile grew a bit wider. "Sorry, Mister. I wouldn't know. I was around for the moving, but I didn't decide why to move what and all that." Just before he continued, he pointed towards the office exit. "We could take a look at it, though."

"Let's do just that, then.", agreed Harry, got up and followed the Warrant Officer out of the room so he could take him to the storage where the mirror was kept.

Halfway across the grounds of the UNIT headquarters, they arrived in front of an open door and looked into the darkness of an unlit, windowless storage hall with a low ceiling. Benton reached around the door frame to flick the light switch. Exposed bulbs dangling above their heads lightened up and revealed several racks in the dusty, cold room. Inside of them laid plenty of small and medium sized boxes filled with items of lesser importance which UNIT had collected from various investigation sites. For an organization that had to deal with chaos on an almost regular basis, the storage was fairly orderly. Harry liked it this way and was just as pleased to find the mirror Benton had been talking of sitting right in front of them.
It was really a rather big mirror. Three foot high at least and it was held by a simple, yet beautiful wooden frame.

"I suppose this is the one?", Harry asked as he approached the object and while Benton voiced his agreement, he decided to pick up the piece of decoration and to place it on a nearby table. Although unhandy and heavy, he eventually managed to arrange the mirror at a comfortable level of height to inspect it from.

"It doesn't seem too unusual to me.", Benton commented, while at the same time, the medical officer examined the object closely.

But that was slightly more difficult than expected. Harry could not help it, his eyes were continuously drawn to look at the well-dressed, young man staring back at him. He had never considered himself as vain, but it was in the nature of a mirror to reveal every little imperfection to oneself and someone as self-critical as he was had to blink twice before he managed to turn his eyes away. Even so, Harry eventually discovered a strange, triangular shape in the mirror's reflection. It had a natural, ochre colour and did not fit with the rest of the picture. As he felt the smooth surface for any unevenness, he noticed that the shape always remained, even when the mirror should have reflected the palm of his hand.

A simple case for the medical officer. It was probably just a small damage underneath the glass, causing the backside of the mirror to shine through. "I say, this thing's just any old mirror.", he told the Warrant Officer with a shrug and moved back from the framed object. Maybe he had been right from the start, the business with the mirror had just lead them astray. Harry shoved his hands into the pockets of his buttoned jacket and looked at the man who had accompanied him here.

"Aw, well. I thought it was worth a shot.", apologized Benton.

They turned around to walk back out of the room. "That's all right.", Harry told him.

But what either of them failed to notice in this moment was that even after they had walked out of the mirror's reach, there was still the image of a man reflected in it. Dressed in a navy blue jacket on top of a white shirt and a neckerchief – a perfect copy of Harry Sullivan. But there was something twisted in the eyes of the reflection. It watched the two military men leave as though it had a mind of its own…

==== ==== End of EPISODE 2 ==== ====

I've struggled more than I should have trying to define how the relationship between the Doctor and Harry works. Sarah and the Doctor is easy, Sarah and Harry slightly more difficult, but still well-defined. But when it comes to having the Doctor interact with Harry or vice-versa, there is surprisingly little season 12 gave me to work with. Both 'Ark in Space' and 'Revenge of the Cyberman' left me with the impression that the Doctor would think of Harry as being slow on the uptake, whereas 'Genesis of the Daleks' and 'The Sontaran Experiment' prove that he trusts Harry with his and other people's lives... The other way around things get even more difficult. Was Harry ever fascinated by the worlds and wonders he encountered during his time as a companion? The fact that he signed off on the first chance he got implies that he was rather intimidated, yet Ian never portrayed him as frightened.

There is also the problem with lots of people either shipping Four/Sarah or Harry/Sarah, which puts the third of the trio in the position of the competitor. While I am mostly okay with either shipping in other fanfictions, I prefer to remove any traces of shipping to allow for the dynamic of them as a trio - something we had too little of in the series (they remained separated for the greater part of the stories).

By now, I'm about to write the ending of the story, but I'd like to have some input on Harry's character, anyway. So please point out to me if you find him doing something out-of-character despite my best efforts in getting him right!
