Watched Robot when I got in from school, and just couldn't resist sneaking inside the head of a certain UNIT medical officer...

Don't own it. If I did, you would all know, believe me

Surgeon-Lieutenant Harry Sullivan, UNIT medical officer, had hardly any contact with the slightly bizarre man, known only as the Doctor, who was UNIT's Scientific Adviser, or the Liverpudlian journalist, Sarah Jane Smith, who was his assistant.

Until the day he got the phone call to come to the lab that the Doctor used.

By the sounds of things, the Doctor had regenerated again, something his colleagues had told him about that he could do - completely change his physiognomy, accent, and personality. And the new Doctor had a much more eccentric outlook on life than his predecessor. For one thing, to stop Harry making him go back to the sickbay, he had got into some sort of skipping game. For another, immediately after said skipping game, he had used the rope to tie Harry up and hang him upside down in the cupboard, to be discovered by Sarah Jane and rescued by the Brigadier.

Of course, he never intended to become a full time member of the TARDIS crew. But two things were responsible for that, his going undercover at Think Tank, and the Doctor telling him to step inside the battered old blue police box, just to prove it was an illusion.

The three of them travelled the universe, forming close friendships, both he and Sarah being the person stuck in the middle occasionally, utterly bewildered. Mostly it was him; Sarah was used to the Doctor's eccentricities. Both the Doctor and Harry kept a close watch over Sarah, although, feminist that she is, would have punched them unbelievably hard if they had said so.

Together they faced Daleks, Wirrn, Sontarans, Cybermen, and Zygons.

After the latter adventure, which involved him getting shot, the Doctor and Sarah getting trapped with out air, his Zygon double attacking Sarah, first by punching her and then by attempting to stab her with a pitchfork, her coming to rescue him from the body print chambers, the Doctor blowing things up (again), and an encounter with the Loch Ness monster, Harry decided enough was enough, and left the crew. The Doctor was more upset than he let on, and Sarah was more than saddened by his departure.

When she finally came back to earth, they shared stories of what had happened since their parting. She had changed. She still looked the same, and acted the same, and was essentially the same, but something had happened and it was a while before she had talked about it.

The Doctor had basically just dropped her off, without a proper goodbye. Harry had been a bit surprised to hear this; she had always been his blind spot.

She had told him this when they were up on the roof of her house one night in November, staring at the stars.

"Do you know where he is now, then?" Harry said, reaching over to give her a hug, as a chill wind blew over South Croydon.

Eyes glistening slightly, Sarah shook her head. But she turned to smile at Harry. "But I bet he's up there," she said indicating the sky.

As the two turned to go back down in search of tea, the star directly over Srah's house, twinkled in reply.
